ur AGM on the 21st March marked the halfway point of my Presidency.... time flies! During this time we can see what a tremendous year of accomplishments it has been for the Federation and its members.
Our Annual Luncheon, which followed the AGM, now incorporates our NFDC Demolition Awards. These awards recognise our members best assets – their employees. As NFDC President it is heartening to see the quality of members employees and the passion and commitment these employees have for our industry. Each and every award entrant that was shortlisted should be as proud as the eventual winners for a fantastic achievement. I would personally like to congratulate Adrian McLean , our recipient of the Man of the Year Award. Adrian’s contribution to making our Demolition Expo 2013 such a success was greatly appreciated by NFDC and IDE members alike, and his award was both well supported and deserved. NFDC Members have also featured strongly in various external awards events, testament to the quality service our members provide.
Not to be left out the Federations very own DRIDS (Demolition & Recycling Information Data Sheets) won the prestigious Bond Dickinson Sustainable Construction & Demolition Award at the Chartered Institute of Waste Management Awards.
Following on from this the NFDC are proud to announce that they are sponsoring the prestigious CIWM UK Sustainability & Resource Industry Awards this year.
Perhaps the biggest single change over the past 12 months to the operation of the Federation has been the appointment of Sophie Cox as our Group Manager. Sophie has overseen the transition and handover from Regional Secretaries to Group Manager, and I am delighted to report this transition has been well received by all five regions. Furthermore we are now beginning to see real efficiencies in the Federations operations that bode extremely well for the future.
Our Chief Executive Officer and Group Manager have steadily built a team at Resurgam House to better serve both NFDC and NDTG members. At the back of this edition take the opportunity to put a face to the name of staff members that are here to
assist with all your membership related enquiries.
If the AGM was the venue to celebrate the success and achievements of the past 12 months, I would now like to look forward to future NFDC events.
In particular, with thanks to the generous support of our sponsors, Liebherr, we will be heading to the Interalpen Hotel in Austria this August. Places are selling fast, so please contact Laura at Resurgam House on: laura@demolition-nfdc.com to make your booking. I look forward to seeing you there.

SYD BISHOP HENLEY’S JETTY
AND SONS K
ent-based demolition contractor
Syd Bishop and Sons has recently completed the demolition of a concrete jetty located on the Thames Estuary. The challenging 12 week project involved the deploying demolition machinery and personnel on a barge in order to access and demolish the structure. The jetty was originally part of W T Henleys cable manufacturing facility located at Northfleet, Kent.
The factory relocated to the site from Woolwich in 1906, a moved that allowed W T Henley’s to manufacture lengths of submarine cable and wind them directly from the factory onto the company’s own cable laying ships moored at the jetty. Although the business led the way in marine cable manufacturing it was taken over by the AEI conglomerate in 1959 which itself
was swallowed up by TT Electronics in 1997.
Despite multiple changes of ownership, production of cables and compound cable coverings continued at the site until 2009 when these undertakings were relocated to Sandwich in Kent. With the cessation of manufacturing on the site, Henley’s jetty, which extended 47 metres from the bank in to the Thames Estuary fell into a state of disrepair. The structure was subsequently earmarked for demolition as part of Northfleet’s Embankment Regeneration Scheme, with the project awarded Syd Bishop and Sons who commenced work in the winter of 2013.
Initial undertakings centred on removing a flood defence gate in order to access the structure and then build a crash barrier
immediately beneath the jetty in order to prevent any debris falling into the estuary during demolition work. Following this, one of the company’s 35 tonne hydraulic excavators was loaded onto a deck barge. The barge was then secured adjacent to the condemned jetty allowing the excavator, complete with pulverising attachment to munch its way through the structure’s reinforced concrete framework one section at a time. A crawler crane was also deployed in order to lift clear those sections of the jetty that could be isolated and removed in sections as well as load and offload skip bins onto a second bulker barge.
Although Syd Bishop and Sons had every confidence it could complete the project within the time allocated by the client, the unpredictable nature of the tide on
DEMOLITION & DISMANTLING - APRIL 2014 7
Appropriate notifications were made to other estuary users via the Port of London Harbourmaster.
Despite the jetty’s location, Syd Bishop and Sons managed an impressive recycling rate of 100%, with the structure’s concrete and steel arisings transported first by barge and then by road to the company’s own state of the art recycling facility in nearby Dartford.
the Thames Estuary meant work was carried out during unusual hours as Tom Bishop, Syd Bishop and Sons’ commercial manager explains, Inconsistent tides meant we were really restricted on how many hours we could work per day, and this varied from week to week as the tidal system changed. For example, with one week we might work from only eleven in the morning until two in the afternoon and others it might be from five in the morning until eleven.
We really had to see how much time the tide gave us work as expeditiously as possible during that window.
Throughout the project, special consideration had to be given to the nature of the demolition, specifically being that it was being undertaken on a busy waterway. Demolition workers were equipped with buoyancy jackets and a emergency rescue boat was kept on alert nearby.
8 DEMOLITION & DISMANTLING - APRIL 2014
Following completion of the project, the company’s machine’s and ancillary equipment were safely returned to dry land and the flood defence gate replaced by a reinforced concrete wall which tied in to the existing flood defence barrier already established along the waterfront. Whilst the jetty’s demise marks the end of cable manufacturing on the Thames Estuary, its safe and expeditious removal heralds a new start for the area which is the focus of sizeable redevelopment and regeneration plans.
WORSLEY PLANT WORKING WITH SLOYAN DOYLE
D
emolition specialists
Sloyan Doyle Demolition have completed a 17 week project in Blackburn in just 14 weeks thanks to the purchase of a Rotar RDP42 pulveriser to use on their Volvo EC700. Liverpool based Sloyan Doyle Demolition, have been at the forefront of demolition, industrial dismantling and recycling in the UK for over 50 years. They undertake general demolition, industrial dismantling, asbestos removal, commercial strip out, temporary works, structural alteration, recycling and site remediation works.
With a wealth of experience, won on major projects throughout the UK, Sloyan Doyle pride themselves that their projects are delivered safely, efficiently, on time, on budget and with consideration for their clients, local people and the environment.
Their most recently completed project was the demolition of a 24,000m2 concrete multi storey structure, formerly the Blackburn Central Markets. This was a high profile project, located in the town centre. There were a number of complications throughout the project, a very tight timescale, with the first phase of the project being handed over just 8 weeks into the overall programme to allow construction of a new bus station.
The need to plan demolition so as to protect an 8m wide culvert running down the centre of the site, carrying the River Blakewater underground. Also, the presence of a very unusual, 32m span concrete shell roof covering the main
10 DEMOLITION & DISMANTLING - APRIL 2014
market hall, comprising precast, prestressed hyperbolic paraboloid units were all concerns during the job.The project was set to take 17 weeks in total to complete but was completed in just 14 weeks thanks to the purchase of a new piece of equipment from Worsley Plant which helped make the job easier and allowing their team to move on to the next job earlier than previously planned.
Sloyan Doyle’s latest investment is a brand new Rotar RDP42 pulveriser from leading demolition attachment specialist Rotar. With its striking red livery, the Rotar range, has an excellent reputation for power, durability and reliability across Europe. It includes scrap shears, sorting/demolition grabs and steel shears amongst other products. The Rotar attachments are sold in the UK exclusively by Worsley Plant, a leading supplier of materials processing equipment to the construction, demolition, landscaping, waste management and recycling industries.
With over 28,000 tonnes of concrete to process, recycling was key to the success of this project. By pre-processing and crushing/screening on site, Sloyan Doyle were able to produce high quality
sub-base material suitable for re-use in follow-on construction works, eliminating over 3000 lorry movements through the town centre.
As with all their projects, Sloyan Doyle looked to re-use or recycle as much as possible of the materials arising from the works, reducing the amount of waste going to landfill and maximising the reclamation of materials. By careful strip out, processing and segregation, over 95% of demolition material on this project was recycled.
Sloyan Doyle contacted Worsley Plant to enquire about the Rotar Pulveriser after seeing it at the Bauma Exhibition in Germany in April. They were impressed by this powerful piece of kit, ideal for a 45-65 tonne excavator, to use on their Volvo EC700 excavator, and are very glad they did.
Sloyan Doyle recognised that the Rotar range is the best on the market and extremely well made. They have already seen results on their first project with the new kit. We continue to work with them to ensure the equipment is working to its optimum level. Sean Heron, MD of Worsley Plant

CONSIDERATE CONSTRUCTORS SCHEME
L.A. MOORE
L
A Moore Ltd was
formed on the 16 August 1952 and in 1969 the Company was granted membership to the National Federation of Demolition Contractors. They undertake all types of demolition and deconstruction work, soft strip, non licensed asbestos removal, site clearance, crushing and recycling of materials.
In 2009 L A Moore Ltd became active members of the Considerate Constructors Scheme and following a recent audit reported that they provide demolition services on a wide range of projects and have developed a substantial reputation for professionalism given their size, scope, and location. All of their activities require and receive “meticulous planning” and clearly achieve the overall criteria of “very limited impact” on the neighbours and general public. The CCS stated that the Directors have placed a very high priority on all aspects of community
12 DEMOLITION & DISMANTLING - APRIL 2014
engagement both for the adjacent affected neighbours and the local communities where works are undertaken.
They reported that their processes are strong and the systems that are in place allow the L A Moore Ltd site teams to use innovative thinking especially with regards to the difficult subject demolition activities within a very busy urban environment produce.
In line with general L A Moore Ltd policy the range of innovative environmental and safety activities brings such benefit to the company employees and sub-contractor organisation alike. Care of the workforce and the range of incentives and training programmes clearly make a major contribution to an enthusiastic and committed overall workforce that is also keen to continue on a programme of process improvement.
Although the various sites/properties are situated in a range of locations from semi-isolated to town centre they were pleased to note that the relationships that the L A Moore Ltd teams appear to cement with such a wide range of affected neighbours, Clients, Main Contractors and the general public across the whole of their Region will be a true legacy activity and hold us in good stead for the future, and in particular our 4th year of registration with the CCS Company Registration Scheme. L A Moore Ltd are honoured to be presented with a Bronze award at the Considerate Award Ceremony held in London in November and are proud to be members of the Scheme.
GROUND BREAKING INNOVATIONS The return of the Rammer brand was never meant to be a final destination; it was merely the first step on a path to further innovation. The latest step on that journey is the new Rammer 5011 hydraulic hammer, an important new model that benefits from a new operating principle to deliver class-leading levels of performance, productivity and power while plugging a gap in the Rammer range. Suitable for carriers from 43 to 80 tons, the Rammer 5011 can be purpose-matched to individual applications and materials. Rammer is not just back. It is back and hitting harder than ever.

BALICRE TOUCHES DOWN AT HEATHROW
EST B
uckinghamshire-based
Balicrest Ltd has recently completed the demolition of a 5 storey office block located next to one of busiest airports in the world. Cardinal House consisted of 3 interconnecting wings and was positioned just 200m from the London’s Heathrow’s northerly runway. With nearly 500,000 aircraft movements a year, the runway is used for approximately 650 take offs and landings every day. The 14 week project commenced in the latter stages of 2013, with undertaking initially consisting of securing the site and soft-stripping the internal fixtures and fixings of the disused building.
During the strip-out many of the block’sinternals had to be damped-down prior to removal in order to prevent lightweight material being blown towards the runway when being ejected from pre-determined drop-zones throughout the building.
The internal work also included removing asbestos material found in the block’s lift cars and pump room.
Prior to the Christmas holiday, conventional demolition of the most southerly wing, and the one closest to the runway, was executed with the assistance of Balicrest Ltd’s Hitachi Zaxis 450 high-reach.
Boasting a pin height of 26m and equipped with a multiprocessor attachment, the machine was easily able to access and dispatch the structure’s higher levels. Working in conduction with the high-reach, a conventional Zaxis 350 excavator, also equipped with multi processor attachment, methodically demolished the building’s lower levels.
With one third of the office block felled, work ceased for the Christmas period. Because of the runway’s close proximity, the gapping cavity left in the side of the building as a result of the first wing’s demise had to be securely sealed-over with scaffolding and tarpaulin for the duration of the festive holiday.
DEMOLITION & DISMANTLING - APRIL 2014 15
Being immediately adjacent to Heathrow Airport and more specifically, one of its runways meant we were constantly monitored by the appropriate airport authorities.
We were responsible for ensuring that little if any dust and absolutely no detritus left the site. Also, because of the extended pause in operations over Christmas we elected to seal and secure the building in a near air-tight manner. David McGee, Balicrest Ltd’s managing director The resumption of operations at the beginning of 2014 saw the second block, at the western end of the site dispatched, again using the duo of Hitachis. Like every stage of the operation, dust control was paramount and a combination of water-based dust suppression techniques were deployed, “Along side using a dedicated Dust Boss water cannon, we also used the high reach’s on board dust suppression system which delivers water to the exact area where its attachment is working.
On top of these techniques we deployed hand-held water cannons to soak down any escaping dust”, explains David.
Although the building’s structure consisted of a conventional RC frame with block and brickwork surround, the process of recovering and recycling these materials was far from straight-forward thanks to the block work being stuck to polystyrene sheeting. In order to separate these respective materials, the building’s exterior had to be stripped away by the HItachis, bulldozed clear of the structure and then separating by hand. In order to fell the final wing of the office block the airport’s taxi rank abutting the site was subject to a 15m exclusion zone enforced with secure fencing. The office block’s on-site sub station which remained live throughout he work was also protected with a steel sheeting during this stage due to its close proximity to the last remaining portion of the building.
16 DEMOLITION & DISMANTLING - APRIL 2014
Throughout the project two smaller Hitachi excavators were used to undertake secondary demolition duties including sorting, stockpiling and loading the resultant demolition arisings.
These machines’ relentless picking and sorting of materials, coupled with manual serration of the building’s exterior walls, helped boost the recycling rate of the demolition to a very respectable 97%. With the building dispatched in a fast and safe manner which also adhered to the airport authorities stringent requirements, Balicrest Ltd was able to return the site to its client in preparation for its future redevelopment.
777 DEMOL CELEBRATE THEIR HALF CENTURY
LITION L
ong-standing NFDC member,
777 Group is celebrating its 50 year anniversary this year. From humble beginnings in the early 1960s, the company has become one of the largest and most well-known names in the industry. Whilst demolition and dismantling still remains a core part of 777 Group’s business, diversification into waste management and asbestos removal have added to its ever-growing turnover, which is expected to exceed in £20m during 2014.
777 Group was originally founded by Mr John Pearce who, having spent several years driving lorries for the military and as well as working for other demolition firms, was well-placed to start his own business in the sector. Within a few years of the company’s inception, John’s son, Michael joined the start-up, assisting his father in
demolishing buildings and selling reclaimed materials. In 1981 Michael purchased the business from his father and started expanding,“When I bought the business it consisted of just two machines and one lorry. Turnover was less than a quarter of a million pounds a year. Soon after I set about expanding it, bringing new people in to work for me and building up a fleet of machinery.
During the sixties and seventies the demolition sector was a fun and enjoyable sector to work in and we really focussed on making sure the company always delivered on its promises by keeping our word and completing jobs to the highest of standards.
Although we now have over forty machines and employ ninety staff I think the ethos of those early years is still retained within the company today”, says Michael.
777 Group’s reputation for being able to deliver on large, often complex projects has led to it fulfilling some unusual and challenging contracts over the years.
These have included the demolition of Gun Wharf Quays in Portsmouth during the mid 1990s; a project that encompassed demolishing the original naval base and excavating 10 metres below ground level. Portsmouth’s original harbour walls were discovered as was a significant amount of discarded ordinance from the last 500 years. In 2007, 777 Group was tasked with dispatching 4 wings at Lewisham Hospital, as part of redeveloping the hospital’s new treatment wing, ‘Riverside’. The project was fulfilled whist the remainder of the hospital continued to care for the sick.
DEMOLITION & DISMANTLING - APRIL 2014 19
The last fifty years has witnessed some marked technological improvements within the industry with machines growing larger and, some would argue safer. This evolution is something 777 Group has been at the forefront of having witnessed the days of manual demolition give way to the ubiquitous ball and chain followed by the advent of tracked excavators which in turn gave way to the giant ultra high reach demolition rigs seen today. “We originally started with two Cat tracked loading shovels and subsequently went on to run a Ruston-Bucyrus RB22 crane fitted with a ball and chain. The mid nineties saw us using some of the first generation high reach machines but the equipment that really reflects our drive to embrace new technology has been put our pair of Hitachi ultra high reach demolition rigs. The first one was delivered in 2003 and at the time it’s purchase was a bit of a jump in to the unknown being unproven and quite a large investment. It proved a success and we bought a second machine in 2007. Although ours are not the only ultra high reach machines
being used today we were one of the first to offer that type of capability and remain synonymous with it”, says Michael. A project in 2011 saw both these giant machines working side-by-side on the banks of the River Thames dispatching a trio of concrete sugar silos on behalf of Tate and Lyle. Investment in other equipment has seen the firm regularly deploy one of the world’s most powerful hydraulic breakers, Atlas Copco’s HB10000. Weighing 10 tonnes, the massive hammer has been used to good effect on several challenging projects since its purchase in 2011.
These have included breaking-out some 50,000m3 of concrete as part of the redevelopment of Woolwich’s Peggy Middleton House and also assisting with the demolition of the former Snodland Cement works facility in Kent. However, not all of the company’s key investments have been on large scale equipment with mini-sized remote controlled Brokk demolition robots also featuring in the company’s equipment line-up.
20 DEMOLITION & DISMANTLING - APRIL 2014
Of course having the right equipment is only one half of the success story, with not only those behind the controls but also involved in every other aspect of the business including safety, finance, training and human resources all essential to the Group’s success.
Whilst demolition remains at the core of 777 Group’s activities, supportive disciplines that include waste management and asbestos removal have also been nurtured and developed under Michael’s tenure. Both have grown significantly in the last 15 years with asbestos removal and disposal carried-out exclusively in-house under a dedicated sub division of the Group with its own license. Likewise, the waste recycling facility immediately adjacent to the company’s headquarters in Croydon, Surrey, has evolved from a simple storage yard to a state-ofthe-art recycling centre. Michael explains further about the growth of this facility, “We originally started processing our own demolition waste at the site but soon developed a market taking other contractors’ waste. The rising
cost of landfill and environmental regulations have meant demand for this service continues to grow. Such is the success of the facility that six years ago we invested several million pounds in a Vecoplan sourced processing plant which gives us the capability to turn incoming material in to refuse derived fuel”.
777 Group’s ability to invest in its employees and equipment, whilst being able to diversify and thrive in supportive complimentary sectors means the company is in an excellent position to enjoy another half century of success in the demolition sector, “The demolition sector has experienced its fair share of ups and downs and that in turn has taught us to remain flexible and not forge profit simply for the sake of revenue. With so much competition in the sector, remaining successful is still about keeping your word by doing what you say you are going to do to the best of your abilities”, surmises Michael.
We have a very progressive attitude to ensuring our staff are suitably qualified, for example all our labourers, operatives and supervisors are all enrolled in the NDTG qualification scheme. Part of our ability to ensure contracts are fulfilled to the highest standards is based on giving our staff the best training available. Failure to do so would mean upset clients, no repeat business and ultimately a contraction of the business. Michael Pearce Managing Director

R COLLARD NEW WASTE RECYCLING UNIT T
he need to recycle our country’s waste materials has never been more important as landfill prices are steadily increasing along with the demise of many landfill facilities. While there is a cost involved in the recycling of materials for both men and machinery, for any company willing to invest significantly in the recycling processes there can also be a long term financial benefit. One such company taking this route and investing heavily in the very latest technology is Hampshire based NFDC members R Collard. Working from their premises in Eversley, Collard
22 DEMOLITION & DISMANTLING - APRIL 2014
operate a multi-disciplined operation including demolition, earthworks and waste management.
Already experienced in the recycling of construction and demolition waste, the decision was made to invest in a high specification system to update their previous trommel and picking station set up. An increase in both their self generated material and material from third parties led the company to look at a massive upgrade to their facility. While the existing plant contained a small hand picking station, all the materials entering the site were tipped on a concrete hard standing
and whilst providing a suitable set up for most companies, this was not how Collards envisaged their set up to look like.
The initial step for the company was to look at potential manufacturers to work with for the construction of the recycling equipment. One of the UK’s premier suppliers of recycling equipment and ISP member, The Blue Group, have recently formed a new alliance with Dmac Engineering resulting in the new venture BlueMAC. The new venture has over 20 years experience in the design, manufacture and installation of waste handling systems and it was
the companies expertise that attracted the management team at Collards. Once the initial design had been agreed and approved, a large shed was constructed at the Eversley site to house the new installation. While the site construction was progressing, the off site manufacturing of the conveyors, picking station and trommel was being undertaken at BlueMac’s headquarters in Northern Ireland. Unlike many manufacturers who buy the various items in and brand as their own, BlueMac will custom design and build a full recycling system to suit their clients requirements. We take in high quality steel, cut weld and paint everything that we produce. explains Daniel McCusker, General Manager for BlueMAC.
The installation at Collards is capable of handling up to C&D waste with the majority being kept dry and undercover. The new installation will increase the throughput for the company significantly. While a drier material entering the recycling station is not absolutely necessary, the increased output and speed of processing makes it more beneficial. The initial process for the waste material once tipped onto the floor is to be loaded into the hopper which feeds it directly into the 2510 trommel screen by another new addition to the Collard fleet, a Liebherr LH24 material handler. Material of 50mm and under pass through the trommel screen and are then conveyed over 50m to the far side of the plant to a flip flop screen via an over-band magnet. The material is transferred into the
fines processing system by a conveyor fitted with a magnetic head roller for smaller ferrous metal extraction which is collected via a chute into a skip. The overhand magnet, one of three on the system, ensures that any valuable scrap metals, no matter how small, are recovered. Looking to recycle between 98 and 99% of all the materials passing through their site, Collards specified the recycling plant to ensure that they can obtain a usable product from even the smallest of waste.
Where conventional screens become inefficient and less economical, the use of a flip flop screen ensures difficult products, such as damp, stalk and leafy materials or matted substances are processed in the most efficient manner. BlueMAC provides a simple solution to these challenging demands: a driving mechanism producing resonance provides two vibratory movements in which the flexible polyurethane panels are expanded and compressed in turns, and the hard-to-screen product is separated at high speed. The 0-10mm material passes through the flip-flow screen while the 10-50mm material passes through a GK air classifier for heavy and lights separation, the light fraction being ideally suited to the production of SRF (solid recovered fuel).
After the trommel the 50mm plus material passes an air separator before entering the picking station, which has been purpose-designed in a six-bay, double-sided configuration with 6 additional drop boxes for high value material such as non-ferrous metals or cabling. The station is comprised of an extra wide cabin for operatives’ safety and has been supplied
complete with industrial specification on wiring, heating and lighting for a comfortable and safe working environment. The picking station’s 1500mm wide conveyor belt, with variable speed, provides optimum material spread allowing maximum recovery. The picking station is separated into eight units all fitted out in the factory and capable of being stripped down into separate parts and transported to another location should the need arise. Unlike many of their competitor’s units, the BlueMAC picking station allows the operatives to stand closer to the conveyor by incorporating a recess for their boots. All the stations have been fitted with anti-fatigue flooring, electric heaters and wide open chutes to deposit the waste through to the skips below.
Collards have also invested heavily in a new Doppstadt DW3060 slow speed shredder enabling the company to take in and process efficiently more green and timber waste. Supplied by the Blue Group, the DW3060 is powered by a 428hp Mercedes Benz diesel engine and is fitted with a 3m long roller containing 21 roller and 22 comb teeth to effectively shred any incoming materials.
Both the installation of the BlueMAC system and the Liebherr and Doppstadt combination represent a massive investment on behalf of R Collard. Although a large investment, the increase in capacity and resulting throughput means that with a massive increase in efficiency the company will see an increase in the profits available for recycled materials.

LYNCH PLA AWARD WINNING SAFETY VIDEO L
ynch's innovative video on Excavator Exclusion Zones has seen them win this year’s prestigious Skanska Supply Chain Health & Safety award. The Excavator Exclusion Zones video is now considered an important tool in contributing to reducing the number of reportable incidents and now plays an integral role in safety presentations at many customers’ demolition or civil sites. Sales Director Rob Lynch commented 'We are delighted to win this prestigious award, Our practical approach to making people safer when walking near plant has influenced thousands of people on site.’
Mobile Plant operations and the interface with workers in the construction industry is one of the highest risk areas for causing injuries, sometimes fatal. Good control measures with plant and pedestrian interface as highlighted in the 'Risk Assessments' (specific to plant operation activities) have identified the measures needed to ensure the safe movement of plant machinery as well as the safety of workers carrying out the task. Therefore Lynch have been proactive to meet the health and safety demands in:
•Operator training •Quick hitch training •Environmental awareness •Strict drugs and alcohol screening •Health & Safety awareness
Lynch Plant created a project team to build awareness in the industry and share best practice. This team led by Senior Operations Manager Mark Kennedy were driven by what they considered to be a lack of clear initiatives with regards to working close to excavators on site.
The project team included Company Training Manager Liam Moore with over 10 years’ experience in operating heavy demolition plant and Company
26 DEMOLITION & DISMANTLING - APRIL 2014
Director Robert Lynch. At first the project team worked utilised the resources supplied by Skanska on 'excavator exclusion zones' and the 'toolbox talk' that supported the exclusion zone poster. They then set about creating a demonstration video that enhanced this training for construction site employees.
The filming took several weeks to produce and when the project team was satisfied the final draft was presented at the 'Skanska' and the Lynch Safety Team for comment and approval.Senior management from Lynch have personally been involved with the role out of the excavator safety exclusion zone training on site across many demolition sites.
Many site operatives and construction office staff are not aware of the dangers working in and around heavy plant on demolition sites, too often site personal walk within the designated working areas of the machines and increase the chance of being injured or crushed to death said Liam Moore, Company Training Manager. ‘’This is a fantastic opportunity to raise greater awareness. Our roadshow gives the chance for all operatives to get up close to heavy plant in a safe controlled environment’’ he added.
Lynch have developed their Lynch Elite Operator Programme which is designed to educate their operators through a number of training programmes such as: Excavator safety exclusion zones, excavator attachment awareness, first Aid training, safety awareness applicable to type of plant operated and constructing better health.
Since the introduction of the exclusion zone training and Elite Operator program, there has been a significant reduction in reportable incidents from near misses to traffic incidents. The decline has been quite dramatic falling from an Average 12.37 per month to 3.25 per month, Lynch has now focused this learning and have introduced similar training for their haulage and transport drivers with a lorry exclusion video to follow this year.
Lynch Plant hire will continue to roll out the road show across other sites during 2014, If you would like to view our ‘excavator safety exclusion zone’ video visit our safety pages on our website or if you would like to order a copy of the video please contact the main office today.

WESSEX DEM NEW DOOSAN T
he ever-increasing number of reduced-tail swing excavators being used by demolition contractors demonstrates a sea-change in attitudes to such machines, with end-users finding such machines more sure-footed, spacious and easy to maintain than expected.
As a result many NFDC members are embracing reduced tail swing excavators. One such company is Wessex Demolition which recently took delivery of a latest generation Doosan DC140LCR reduced tail swing excavator. Demolition & Dismantling took a closer look at its latest acquisition and how it was faring whilst carrying out a challenging demolition project in Hampshire.
MOLITION The latest dash 3 DX140LCR was launched in the Summer of 2013 and hosts a Stage IIIB complaint Cummings turbo charged engine facilitating an increase in power and torque of around 10 % compared to the previous model.
Lifting capability as well as arm and bucket forces have also been increased by 7%. An all-new cab comes equipped with creature comforts such as adjustable air conditioning and heated air suspension seat as standard. With an overhang of just 5” when working across the undercarriage, the DX140LR’s upper structure in one third the length of Doosan’s conventional 16 tonne excavator, the DX140LC, thereby making it ideally suited for confined demolition operations.
Unsurprisingly, Wessex Demolition’s machine sports full demolition specification configuration which includes ram guards, belly plates and FOPS cab guard. Additionally, the Doosan sports a 3 metre dipper arm, a length some 50cm longer than standard specced machines. This choice was made in order to ensure maximum productivity and safety according to Wessex Demolition’s contracts manager, Ashley Grant, “By investing in a machine that is compact but extremely capable with excellent reach, we can dispatch structures located in confined and restricted spaces that would have previously required manual demolition. This not only improves safety by reducing labourers’ exposure to font-line demolition work but also boosts efficiency by minimising the number of personnel required on site”.
Wessex Demolition used its new Doosan DX140LR to good effect when demolishing a block of 6 flats, owned by a housing association in the heart of Petersfield, Hampshire. The dwellings had been left empty for some time and
as a result squatters and drug dealers had taken-up residence until just prior to demolition. The flats themselves were located in a quiet cul-de-sac surrounded by assisted living properties. “Although the condemned building’s structure presented no problems in itself, its position, on top of a raised embankment, and the close proximity of other flats nearby meant our new reduced tail swing excavator was the ideal tool for the job”, explains Ashley.
Initial work included securing the site and creating a flat, clear entry point to the site by excavating a portion of the embankment. With a welfare unit safely installed on the level terrain, work could begin clearing the detritus left inside the flats; this included carrying-out a needle sweep of the flats in order to remove any needles discarded by the squatters. A soft strip was then undertaken before the removal of a small amount of notifiable asbestos. With the flats now primed for demolition, the DX140LR was brought to bare on the structure. At the controls of the new machine was Paul Beaumont who, having previously operated a 5 tonne Doosan for Wessex Demolition was familiar with the manufacturer’s
equipment and suitably impressed with the new excavator, The Doosan is comfortable, quiet and very stable, even with the extended dipper arm and reduced tail swing, says Paul.
With a maximum forward reach of 8.7m and a pin height of 8.4m, the Doosan proved more than capable in dispatching the two storey structure, a task which involved working in confined positions immediately adjacent to neighbouring buildings and perimeter fencing. The DX140R utilised a Mantovanibenne GR 850 rotating grab attachment which proved an ideal tool to not only demolish the structure but also separate and stockpile the resulting arisings in a timely manner.
With Wessex Demolition’s Doosan having clocked up 300 hours, this small but perfectly formed machine looks sets to continue making demolition projects of a confined and restrictive nature safer and more profitable for the Hampshire-based company.

GNAT UK
YORK CITY CENTRE OFFICE BLOCK C
onversion of a major York City centre office block into luxury flats has been completed 20 weeks early, thanks to an eleventh hour switch from conventional percussive demolition to more environmentally friendly concrete sawing and stitch drilling cutting techniques. Concrete Cutting specialist Gnat UK completed the removal of three crucial concrete walkways using relatively noiseless 'cut and carve' sawing in a fraction of the time allocated to the original demolition contractor.
They proved a competent professional alternative and came up with an innovative solution to our last minute problem, saving us all time and money, says Jason Gill, construction manager for main contractor Wood Mitchell Contracting.
30 DEMOLITION & DISMANTLING - APRIL 2014
"It was a good safe job and we would definitely look to employ Gnat again given a similar challenge."
Rougier Street provides not only important access to underground parking for insurance company Aviva offices, which line both sides of this narrow back road, but - even more crucially - is the vital service route to a prestigious five star hotel. Above the road, and spanning between the office blocks on either side, sat three 6m long enclosed reinforced concrete walkways, each directly above the other at different heights and offering no longer needed pedestrian access between the offices. The challenge was to remove these 2.4m wide walkways leaving the road beneath with continuous vehicular access and by causing minimum disturbance to the 740 office workers at their desks, some
just 1.5m from the demolition work.
Removal by the originally appointed demolition contractor, using percussive jack hammers, lasted only a few hours before complaints from the office workers about excessive vibration and noise halted all work. Gnat UK was asked to come up with an alternative solution by the demolition contractor and, working alongside scaffolding contractor SAY Scaffolding, plus structural engineer Bland and Swift, proposed a cutting plan to operate within an engineered three-tier scaffold. Access for road traffic was to be maintained by incorporating a portal frame arch into the scaffolding. Each of the three walkways, housed within its own independently supported scaffold and crash deck, was cut up into five sections and lowered by a crane sitting in the road beneath.
After each walkway was removed, the scaffold section supporting it was dismantled from the top down providing access to the walkway beneath and enabling the 50t crane to easily lower average 4.3m cut sections to street-based skips. "Working from the crash platform immediately beneath each walkway we used a Hilti TS 20 Electric track saw, fitted with inverted blades, to saw upwards into the concrete forming raking cuts," explains Gnat UK project director Mike Hill.
"Cuts were finished with inverted stitch drilling by a Hilti DD550 rig, and 150mm diameter holes cored for lifting frame chains using a Hilti DD350 rig."
Vibration and noise levels were minimal compared to the proposed conventional demolition techniques and Gnat UK completed the contract four days inside the programmed four weeks.

CONNELL BR TRANSFORMING ROCHDALE R
ochdale town centre is set to transform beyond recognition in the coming months now that NFDC members Connell Brothers have been appointed to start the demolition of the old Municipal Offices and Bus Station. The demolition will clear the way for Genr8’s proposed new mixed use retail and leisure development in the heart of the town centre close to the new Transport Interchange which opened in November 2013, and town centre Metrolink stop, which is on track to open in spring.
The task of demolishing the structures that have dominated Rochdale’s skyline since the 1970s will fall to Connell Brothers Ltd, of Salford, who expect the project to take around nine months to complete. Preparatory works have been taking place over the last few weeks, and Connell Brothers are now getting the site ready for the main demolition works. Work to remove the two ramps to the car park above the old bus station will start in late February ahead of the main demolition works starting in early March. When the main
32 DEMOLITION & DISMANTLING - APRIL 2014
demolition gets under way the Multi Storey Car Park and old Bus Station will be the first area to be demolished followed by the old Municipal Offices.
The demolition of the old black box will be a delicate task for Connell’s who will have to first internally strip out the building before covering it with scaffolding and dismantling it from the top down because of its proximity to Metrolink and other buildings in the town centre, as well as pavements and roads. Hoardings
ROTHERS are being placed around the demolition site and will be decorated with colourful designs promoting the town centre and giving people directions to key locations.
The webcam which was previously stationed on top of the old municipal offices has now been moved to the Number One Riverside to give people a unique insight into the next stage of work in the town centre. The webcam images can be viewed at: www.rochdaletowncentre.com Councillor Peter Williams, Cabinet Member for Economic Development at Rochdale Borough Council, said:
“This is a big step forward in the regeneration of Rochdale town centre. It’s the end of an era for many wellknown buildings but is also a much needed move into the 21st century which I’m sure will be welcomed by many.”
I’d like to thank our businesses and shoppers for their patience during the inevitable disruption and am pleased to say that the end result will be a significantly better town centre for all of us. We have a wealth of experience working in restrictive city centre environments throughout the UK. Steve Balyski, Operations manager of Connell Brothers Ltd
The team who will be working on the Rochdale project has been responsible for the virtual re-modelling of large parts of the city centre of Manchester including Mosley Street where we successfully
demolished Elisabeth House, the former Royal Bank of Scotland and Eagle Star House. “This experience means we’re in a really good position to make the huge changes required in Rochdale while minimising disruption for the public and keeping them safe.”
WOOLDRIDGE FELL PHARMACEUTICALS FACILITY S
urrey-based Wooldridge Demolition is currently demolishing the final portion of a former chemical research and development facility near Bromley, Kent. The site was originally part of a large country estate known as Langley Court and was used to house officer prisoners during the First World War. After the war Langley Court began to house research and development activities with the establishment of the Wellcome Physiological Research Laboratories in 1921. In the following years the facility grew in size with Wellcome Chemical Research Laboratories relocating there from Euston Road in 1946. The facility continued to be used until the mid 1990’s for penicillin production and research into biological products including vaccines for Polio.
From 1995, pharmaceutical-related operations were gradually wounddown at the site and portions sold off for redevelopment. The last remaining section of the site which housed 9 industrial buildings including offices and laboratories was approved for redevelopment in 2012. Under the redevelopment plan, which includes building 179 houses,
DEMOLITION a medical surgery, a sports academy and community hall, the now defunct pharmaceutical buildings have all been earmarked for demolition, a 6 month-long undertaking which Wooldridge Demolition began at the beginning of 2014.
The site was split in to two sections with phase one consisting of the demolition of a handful of research laboratories and a storage/distribution building. Although further buildings have also been earmarked for demolition in the first phase they are currently home to roosting bats and will therefore be left intact until the bats are rehoused.
Soft-stripping of the laboratories had already been completed by Wooldridge Demolition previously, during the period between when activity at the facility had ceased and approval was granted for the new housing development so mechanical demolition of the buildings commenced without delay. In order to fell the three storey laboratories, Wooldridge Demolition deployed its Volvo EC480D high reach demolition rig, complete with
multiprocessor attachment. With a pin height of 26 metres, the Volvo was capable of demolishing the buildings section, by section in a safe and controlled fashion. Having been built specifically for use as laboratories, their form was nothing short of robust as Nick Anderson, Wooldridge Demolition’s director explains, “Because the buildings housed a great deal of heavy pharmaceutical machinery and equipment as well as an extensive latticework of air condition, ventilation and plumbing pipework and ducting, they were extremely well engineered with walls and floors made of extra-thick reinforced concrete. Thankfully we were able to utilise a modern, powerful demolition rig to bring the structures down quickly and safely without incurring delays”.
Working in conjunction with the high reach was a 65 tonne Hitachi excavator. This heavyweight machine was used to good effect to expose the structures’ basements and fill them in with rubble ensuring the high reach Volvo could work on stable ground at all times. A fleet of smaller
equipment including skid steers and 20 tonne excavators were also deployed to support the demolition operation and sort the resultant arisings so they could be recycled.
Because much of the surrounding area had already been redeveloped, principally in to housing, extra care was taken to reduce and mitigate the effects of the demolition work. This included dispatching the buildings in a specific order, keeping those on the perimeter standing until last thereby providing a barrier for any erroneous noise or dust generated whilst the bulk of the works are being completed.
With phase one of the demolition approaching completion, the second phase is expected to be similar in nature with a number of laboratories to be demolished along with the office block located at the front of the facility. Completion of this second phase will mark the end of the site’s association with pharmaceutical development and production with only the on-site cricket pitch and pavilion built for employees being retained for use by the new community.
DEMOLITION & DISMANTLING - APRIL 2014 35
CENTRAL DE SCOTLAND'S STEEL WORK SPECIALISTS
C
entral Demolition are close to completing a large contract in East Kilbride which has been underway for a substantial amount of time. After several visits to their new offices I was able to persuade their Contracts Manager, Mr. Allan Bell, to give me the details of the project.
The contract relates to premises located on the former Freescale site on Colvilles Road, and is one of Central Demolition's largest and most challenging undertakings in recent years. Senior site manager Mr Jock Shaw was chosen to be on-site manager for this contract. One of Scotland's foremost steel burners, Jock has over thirty years' experience in the safe removal of large steel structures. His most notorious past claims to fame being John Brown Shipyard in Clydebank which had over 30,000 tons of steel and British Alcan in Burntisland which reached over 24,000 tons. This reputation can only be consolidated by his success in managing this contract.
Even prior to the actual demolition work commencing, a large number of different specialist facilities in the buildings had to be decommissioned. These includes three D-I (deionisation) plants used in the production of ultra-pure water, which was in turn used for the manufacture of silicon. The pipe work running through the site contained hydrogen, nitrogen and other chemical and acid types specific for electronic manufacture all of which had to be purged. While Freescale had carried out a systems purge of the pipes prior to handover of the site, Jock still had to be mindful of the residual risk presented by these systems.
Every single pipe, regardless of dimension, was examined individually and assessed for contamination and physical contact risks. Where any such risk was identified, the on-site team used water to further flush the pipes through to remove the residue. This was essential in areas where there was the risk of pooling. Jock ensured the safety
of his team by making sure that everything was flushed through prior to removal: his care is shown by the fact that there has not been a single instance of an individual coming into contact with any of the aforementioned substances.
During the three-month handover period, Freescale removed the equipment they wished to retain from the site.
That which remained fell to Central Demolition, who were subsequently able to sell it to interested parties via an auction house. They continued to make good use of this three-month period, using it as an opportunity to familiarise themselves with the site layout. By the time the demolition operatives arrived, the layout of the buildings and any potential problems were clearly understood. The scale of the site was such that the opportunity for staff and employees to get to know it was invaluable, and provided for far greater work efficiency upon arrival.
EMOLITION However, the minor location awareness issues that remained were somewhat exacerbated by the absence of light and power: these services had been cut off prior to demolition. This admirable - if somewhat uncharacteristic - efficiency on the part of the utility companies also caused some issues during the removals and cataloguing: this all had to be carried out in artificial lighting, the limitations of which carries inherent problems.
This was a uniquely challenging contract. During their occupation of the site, Freescale had extended their buildings on several occasions, constructing sheds on an ad hoc basis as their facility needs shifted. While this provided a quick solution to their immediate accommodation problems, the lack of consistency in construction methods caused challenges during demolition: load paths and steel dimensions differed across the sheds, necessitating different approaches to each. The single constant factor was the significant amount of steel in these buildings; they contained not only steel supports, but internal steel work and other components as well.
The contract involved huge amounts of steel work, all of which has to be taken down safely and processed; this was of particular importance where structures were located adjacent to roads or facilities that house sensitive equipment. Freescale themselves retained the former office section of the building which was attached to one of the buildings in the works area. At present it houses highly sensitive electronic equipment used to test chips and other items.
This equipment is so sensitive to vibrations that Central Demolition are required to not only maintain a set distance from the buildings in which they are housed, but also to monitor the vibrations generated by their work to ensure that they are kept below the potentially problematic levels. These are not standard vibration levels according to demolition criteria, but a far lower level that safeguards the electronic testing equipment. Due to Central Demolition's careful control measures and monitoring, acceptable vibration levels have not been exceeded and the integrity of the testing equipment has not been compromised.
The site contained a lot of non-ferrous metals due to the nature of the buildings it contained and their materials: stainless steel is only one such example. There were also a lot of plastics, all of which had to be segregated and cleaned before being sent for recycling. The generators, plant, electrical systems, transformers and other items were all sold on to third parties; this means that the vast majority of items were recycled, the exception being insulation which had to go to landfill: this has resulted in a recycling rate of approximately ninety percent by weight volume to date.
On a demolition contract of this scale and complexity, particularly when considered in conjunction with the lack of incidents, to achieve such a high percentage is evidence of the considerable skills of site-manager Jock and colleagues.
73 RD ANNUAL GENERAL MEETING & DEMOLITION AWARDS 2014 A return to the Dorchester in London’s Park Lane for the NFDC’s 73rd Annual General Meeting and Awards ceremony saw a record attendance from both Members and Associates. With the AGM officially opened the stage was taken by Mike Swain to update the attendees on the Federations accounts. Overall income increased significantly thanks to the Gleneagles Convention being organised internally and subscriptions from both Members and ISPs increasing too though restructuring regional secretariat caused the overall figures to show a one off loss. The once loss making Demolition and Dismantling magazine has been brought in-house and is now returning a small profit. NFDC President William Sinclair opened the days proceedings to a packed room, enthusing on the steady upturn in the industry over the previous 12 months.
Speaking on his first 12 months in office, Mr Sinclair commented that his election to office coincided with the Federations most significant appointment to date, that of appointing Sophie Cox as Group Manager. Reporting to the audience that the appointment was well received by both Executives and Members alike and that the ease of transition was down to the hard work undertaken by all parties. Mr Sinclair then went on to congratulate the partnership formed with the IDE to establish the inaugural DemoExpo held at the Arden Brickworks. Special thanks were offered to Adrian McLean for the hard work and effort his company, Armac, put into staging the event.
Recognising the role that ISP’s play in the Federation, Mr Sinclair announced that Second Vice President, Andrew Forshaw was appointed ISP Member Liaison with a role to represent Members at National Council. Mr Forshaw’s first meeting was held in September of 2013 with future meetings to be announced. At the initial ISP meeting it was agreed that the second Demo Expo will be staged in 2015. Mr Sinclair then explained that under PR and Marketing Executive Louise Calam, the Federation has now brought the D&D magazine, the Yearbook and the Federation website in-house. Commenting on the success of the Gleneagles Convention Mr Sinclair thanked the main sponsor, Liebherr for their continued,
generous support. Mr Sinclair then thanked and recognised the contribution by Patrick Williamson for his help with the organisation of the previous years conventions. Moving on to the recent regional AGM’s held in January Mr Sinclair then commented on the common bond and goal from the Members to maintain the highest standards possible within this industry. This is born out by NFDC Members regularly being nominated and winning awards across the UK and Europe. Mr Sinclair also commented on how impressed he was at the sound financial footing which the NFDC has before rounding off by thanking his past President and current Vice Presidents and the staff at Resurgam House.
Next to speak was NFDC CEO Howard Button. Reporting on the previous 12 months activities at Resurgam House, Mr Button offered members clarification on the first year of the DRIDS and it’s award from the Chartered Institute of Waste Management in November last year. Mr Button also commented on the forthcoming launch of the website and the responsive attributes that will allow it to be view across many platforms .
Announcing DRIDS training days, Mr Button said that the uptake is very promising with many members taking up the offer of training sessions. Non-Federation Members are also showing a healthy interest in the system and Mr Button explained that many large construction companies have provided feedback. Moving on to the Federation produced guidance notes, it was noted that there are three sets of guidance notes including exclusion zones, specification for scaffolding and the long awaited disconnection of services in the pipe-line. Mr Button commented on the upgrade of the website to include DRIDS and the regularly updated news section. Commenting on the partnering with ARCA and ACAD to form ARMI the Asbestos Removal and Management Institute to ensure the Federation are represented to the full. The world’s first demolition plant simulator has been in operation almost 12 months and Mr Button commented on how well received and successful the simulator has been so far.
Group Manager Sophie Cox took to the stage to comment on her first 12 months in the role. Mrs Cox was pleased to see the regions adopting national processes yet still retaining their individuality. Commenting on increased applications Mrs Cox stated that the applicants are now much better informed throughout the various application stages with help and support on auditing processes being offered. Twenty new ISP’s and seven Corporate Members joined the federation within the previous 12 months. Bringing the regions in-house has led to much better communications with all regional meeting dates and events sent out through the database and with ISP’s now able to attend has not only boosted attendance but has increased the networking opportunities for all involved. With all meetings now held within a two week period, Mrs Cox explained that the Members are better informed with information and any training courses available. Mrs Cox explained that the previous 12 months has brought the NFDC and NDTG closer together with the Group striving to ensure NVQ qualifications are delivered to the highest of standards through a network of demolition assessors and centre staff.
Over two hundred NVQs have been issued over the past 12 months and with four intakes of apprentices being taken for the 24 month specialist apprenticeship program, with another four groups to come, the future for the demolition industry is looking very healthy. Training figures have increased by 20% from 2012 with over 7000 training certificates being issued for industry training. The NDTG has also offered over 45 fully funded training courses according to Mrs Cox. The most notable achievement for the past year according to Mrs Cox was the launch of the demolition plant simulator. The current software that has been developed in conjunction with Volvo assists novice operators and avoids the limitations found on site in real time situations. While the time honoured method of training operatives is still preferred, constraints laid down by principal contractors and site restrictions often prohibit this practice thus the simulator has been designed to train candidates in foundation core skills in plant operation in a safe environment. “While on site training is still required we are hoping this foundation course will lift some of the restrictions on this practice.” explained Mrs Cox. Mrs Cox also went on to add that the NDTG were invited to showcase the simulator and training courses at the National Skills Show in Birmingham recently and that the simulator has been attracting positive comments throughout the demolition and wider industries. Mrs Cox also commented on the past two years service at the helm of the NDTG Training Group by Richard Dolman and thanked him for his stirling service. Mrs Cox also thanked both the NFDC and NDTG Executive Committees, the Regional Chairmen, Officers and Members for their support offer the last 12 months restructuring.
PR and Marketing Executive Louise Calam reported on the re-launch of the now profitable Demolition & Dismantling magazine and the increase in communications from Resurgam House to the members. Miss Calam also reported on the increase in traffic to the Federation websites’ using social media such as Facebook and Twitter, and marketing techniques through SEO’s and analytics. Using the analytics Miss Calam reported that the website received just over of 200,000 page views last year and has set herself a target to increase this number by 58% for this year. According to Miss Calam there will also be a video produced to explain the Federation’s marketing on topics such as the Demolition & Dismantling magazine, websites, social media, meetings, events and communications.
Ending the official proceedings was the IDE Vice President, Duncan Rudall. Mr Rudall spoke about the turbulent time in the past year and the significant changes made to correct these measures. Mr Rudall enthused about the steadily rising membership of the IDE explaining that a further 12 full members have qualified since last November with a further 20 making the grade by the time you read this. This includes three full European Members. Mr Rudall then went on to talk about the two seminars and seven regional meetings held last year which will be repeated this year. Mr Rudall reviewed in brief the previous Seminar in Leeds and the emotive speakers including teenage cancer sufferer Stephen Sutton. As is the norm with the industry, over £1000 was raised at the event for Stephen’s charity. Teenage Cancer Trust. Mr Rudall then finished off stating it is his intention, under his forthcoming Presidency, to bring the IDE and NFDC closer together to promote to clients that it is the best way to progress with demolition projects.

NFDC President William Sinclair then retook to lectern to congratulate two long serving and highly respected ISP members: Ron Callan from Kocurek and Alan Matchett from Rammer. Presenting them each with a cut glass decanter, Mr Sinclair thanked them for all their help and assistance to many members over the preceding years.
After lunch to the exceptionally high standards befitting to the surroundings, saw the start of the Demolition Awards 2014 hosted by one time UK number one tennis player, Andrew Castle. After regaling the audience with his life in the shadows of such tennis greats as Borg, Sampras and Agassi, his spell on early morning breakfast TV and his phone calls from politicians wanting to play tennis,attention turned to the forthcoming awards.
The awards started of with the Demolition Operative of the Year sponsored by Brown and Mason with a highly commended award going to James McFarlane of Central Demolition and the winner’s award being presented to Bogdan Landowski of P P O’Connor. Bogdan’s nomination submitted from his manager, expressed: ‘Bogdan Landowski has shown outstanding ability with his enthusiasm and professionalism carrying out demolition activities. Bogdan strives to become a senior member within the demolition project team.’
The Demolition Plant Operative of the Year award sponsored by Rammer went to Neil Herbert of DSM with a highly commended going to Andrew Hinton of Lawson Demolition. Neil’s 27 page nomination papers throughly detailed his reasons for nomination, curriculum vitae, certificates, written submission from Neil and a written submission from the employer. ‘It is with great pleasure that we nominate Neil Herbert for the Demolition Plant Operative of the Year Award. From the day he walked into the yard asking to drive one of the machines, he had a positive ‘can do’ attitude along with a drive to better himself and set his own career path.’
IDE President Steve Jack then presented Michael Kelly of Keltbray with the Erith sponsored Demolition Manager of the Year award with Paul Sharkey of Dem-Master gaining a highly commended award. Michael Kelly’s enormous 95 page nomination provided informative detail to the reasons why he should win the award. Operations Director Jim O’Sullivan commented: ‘Mick Kelly has a fantastic attitude to work and id passionate about demolition. He has progressed through the ranks proving himself at every stage and is now a top demolition project manager responsible for the delivery of many of Keltbray’s most prestigious projects. Recently elected NDTG Chairman Gary Bishop presented the Demolition Training Award – sponsored by NDTG to Central Demolition. Central Demolition submitted over 33 employees with CCDO, CPCS and training certificates from NDTG Scotland. Highly Commended from this category went to A R Demolition.
The NFDC’s 2nd Vice President & ISP Liaison Representative, Andrew Forshaw, presented the Demolition Innovation Award-ISP, to Liebherr GB with a collaboration between Armac Group, Kocurek and ECY Haulmark obtaining a highly commended award. Liebherr GB submitted several nominations, however the overall ISP Innovation that stood out was the Liebherr Demolition Control (LDC) System. The system guarantees safe working conditions at all times, in a working area of 360 degrees around the machine.This is accomplished through permanent, fully automatic monitoring of tool movements and tilt of the machine so that the stability of the excavator can be warranted as well as safe working conditions.
The Demolition Innovation Award - Corporate was presented by Howard Button NFDC CEO. To McGee Group with Lawson Demolition receiving a highly commended award. The McGee Group submitted an outstanding innovation entitled: ‘360 degrees Mobile Visual Noise Indicator’ with benefits including instant response time, reduction in neighbourhood complaints, 360 degree visual indicator, waterproof, weatherproof and easy to set up.
One of our new awards - Investing in Skills for a New Generation sponsored by CITB was presented by Paul Gaze - CSkills Specialist Federations Manager to Coleman & Company with Thompsons of Prudhoe being highly recommended. Coleman & Company submitted how they have invested in skills for a new generation by outlining apprenticeship programs, taking on college students and university graduates and work experience placements.
Finally the John Bergin Man or the Year Award went to Adrian McLean of Armac Group for all his hard work and dedication throughout Demolition Expo 2013. The date of the next AGM will be on the 13th March 2015 at the Dorchester, Park Lane.

GILPIN DEMO ABBEY ROAD BRIDGE I
n recent years, Gilpin Demolition have slowly established themselves as one of the front runners in the UK for bridge demolition and have continued to expand in this field, winning key contracts throughout Southern England. It was therefore no surprise when Gilpin Demolition were awarded the contract to demolish the existing bridge and viaduct at Abbey Road in Evesham, explains Gilpin engineer Jason Vincent. With a strong background in bridge demolition and an established working relationship with main contractor Hochtief UK, it was inevitable that the two companies would need to work close together to deliver this challenging and intricate project.
The existing structure is comprised of a 28 span reinforced concrete viaduct over a flood plain and a 30m reinforced concrete arch bridge over the River Avon, providing the vital link into the town centre of Evesham. The existing structure has been slowly deteriorating for more than 60 years, causing a reduction in the load capacity and has now reached a state where it needs to be replaced.
“Hochtief were under considerable pressure from the local council from the outset to get the bridge replaced in the shortest time possible” explains Jason.
“The closure of this bridge caused a lot of concern from local residents and businesses as it is the main route into Evesham and every person in the town would be affected from this. Hochtief developed a challenging programme to complete all aspect of the works, which outlined plans to demolish the existing structure at the same time as the construction of its replacement.”
With the road closure booked for September 2013, pre-enabling works started on site in April to remove the existing pilasters, pilaster retaining walls and approach staircases, working within lane closures.
OLITION “At this point it was clear to see just how congested Evesham became with only one lane open to all traffic. It certainly outlined to us the pressure that we would be working under during the road closure to complete our part of the works within the allocated programme” says Jason. With a relatively short time frame to work within, Hochtief looked to Gilpin to develop a methodology that was both practicable and deliverable to allow construction works to occur alongside the demolition works. The first stage of the project would see the 28 span viaduct removed first, systematically removing the surfacing material and demolishing each span from the river back towards the North abutment, using a combination of 35t and 20t machines munching the concrete deck and piers.
Due to the temporary stability of the viaduct, we had to ensure our 20 tonne machine was positioned 2 spans behind the one it was working on at all times and positioned on 150mm depth timber mats to ensure the load of the machine was spread evenly between the piers.
The machine moved the mats behind itself and works continued down the length of the viaduct like this, with the 35t machines working at ground level following it towards the abutment” says Jason.
At this stage, Hochtief had set out and constructed the new concrete piers beneath the existing viaduct and each one had to be wrapped with conveyor belt rubber material to prevent damage from falling concrete debris. The new footpaths had also been constructed for the entire length of the viaduct meaning Gilpin had to continually reach over these to aid the demolition. All material was moved from the flood plain area and processed by the 35t machines into designated areas on site.
“The viaduct demolition was the easy bit!” jokes Jason. “Once we had the first span out it was very systematic and all spans were removed in line with the programme. Hochtief began constructing the new deck in between the footpaths as soon as we had removed the first two spans and they were chasing us all of the way towards the abutment. We had to leave the first viaduct span adjacent
to the bridge left standing, so to give us much needed working room when removing the river span”. The tricky part of the job and the major challenge was the main concrete arch span over the river. The span comprised of a 250mm thick reinforced concrete deck slab supported by 8 concrete cross beams each weighing 12 tonnes, with a lower stringcourse beam on each side and the main concrete arch beams on each side with hangers connecting to the deck.
Working above the River Avon bought with it its own challenges as well, as no material was allowed to enter the watercourse at any stage. Safety barges were a mandatory requirement for the job and if the water level reached a certain level, all works had to be stopped adding to the pressure of delivering the job.
At this stage Hochtief used the curvature of the existing concrete arches as shuttering to pour the new arches above and connected these to the new steel cross girders beneath the existing deck via 18 vertical steel bars on each side of the bridge. These bars were not allowed to be damaged
DEMOLITION & DISMANTLING - APRIL 2014 47
in any way and demolition methods had to be derived from the restraints placed by these.
A methodology was developed where two 35t machines sat opposite each other in the centre of the span and firstly lifted the deck slabs out, which were saw cut into manageable pieces. These could then track back, one side over the abutment onto land and on the other side onto the remaining viaduct span via an engineered steel deck spanning the 3m gap between the bridge and the viaduct and lifted down for processing.
This then exposed the concrete cross beams beneath which again were cut into 2 equal sections and lifted out. When completed the trapped machine could track onto the remaining viaduct span and track off of the newly constructed bridge adjacent to it, then use this as access to demolish the last span.
“The weights for all of the sections had been calculated using existing drawings and measurements on site and the 35t machines with chains lifted the concrete deck between the cross beams in equal sections. We removed the first cross beam in one go in order to save time but this proved difficult to manoeuvre and close to the machines capacity, so we had to adapt the method to remove the rest in two pieces. This involved propping one half whilst lifting the other and ate into valuable time”.
“We also had to lay a temporary 150mm thick timer mat deck on top of the new cross beams as we worked backwards, so that we could access at a later stage with smaller plant. The new cross beams beneath had a 5 tonne load limit, so all machines had to weigh less than this” says Jason.
With all slab sections and beams removed and the temporary deck fully laid, Gilpin were able to access the remaining stringcourse and hangers with small plant, which were preventing the construction of the new deck elements.
These were removed by a combination of saw cutting the concrete and using mini diggers, ensuring no vibrations were transferred to the vertical steel bars. All works were undertaken above a barge so no material could enter the watercourse, with bad weather an ever presence in preventing the barge gaining access and further delaying the job.
Both Gilpin and Hochtief have been tested to the limit with this job and it’s one where we have all learned and gained experience from, due to a methodology which had to continually change to reflect on site conditions. If construction was delayed then this would ultimately affect our demolition programme. We had to continuously work around construction work and adapt the demolition method to account for ever changing scenarios. It is an exciting project to have been involved with and we look forward to seeing the new structure completed and in use for the people of Evesham.
At this stage, with the existing deck components gone, the temporary timber deck was removed and Hochtief were able to complete the construction of the new deck and footpath elements. With bad weather and high river levels constantly threatening the delivery of the project, Gilpin are due to return to Evesham to remove the final concrete arches at the start of February to signify the completion of the demolition works. It’s a job that all at Gilpin are looking forward to seeing over the finishing line says Jason.

CAWARDEN DEMOLITION THREE TOWERS C
awarden Co Ltd, Midlands and Welsh NFDC members, have recently undertaken the demolition of three 30 metre plus high towers, all of dissimilar structures and each requiring a different technique to ensure they were removed safely, on time and as per the clients instructions. The first of these towers was undertaken in January 2013 and was situated within the live Tarmac Plant near Swadlincote, Derbyshire. The contract was for Tarmac PLC and their specification consisted of removing the top 15metres of the mixing tower,cutting out internal plant and services, and leaving the steelwork cut to an angle that would allow the remaining structure to be over clad, each tower removed by Cawarden was at a separate location and in completely different surroundings.
Parameters of this building included having other buildings all around the tower, with a second twin tower at a distance of only 30metres. Railway lines lay some 50metres away and machinery was still in use inside the first 20metres of the tower to be taken down. After meeting with Tarmac engineers, Cawardens method of works were agreed by both parties and they were advised it was a nesting site for peregrine falcons
so the whole project, including the re-roof, had to be completed by the end of February! The site manager Mick Whitehead commented that the biggest problem they had was the extreme cold and high winds, which did delay the final lift by one week, otherwise all went to plan accordingly. The second tower was undertaken by Cawarden in July 2013 and was situated in a rural location near Cresswell in Staffordshire. This water header tank stood in the middle of fields accessed only down a long narrow private drive, which led to a house situated 60metres from the 30metre high platform with a 20m x 15m Braithwaite water tank sat on top.
Staffordshire Water had no access into the farmer’s field and one boundary fence was situated at the base of the tower. On no account could Cawardens allow any steel, rust etc. to drop into the farmer’s field and they were asked to take it down ASAP.
Cawarden could only get a telehandler and a lift up to the tower and the steel had to be removed in swing skip bins. The method in this case was: • Cut away all external fittings, water pipes, ladders and cables • Access the tank using cherry pickers and oxy propane cut the tank
lowering the steel via a high reach teleporter • Place the steel into 10 yard skips and continue until completion
The site manager and top burner Malcolm Lowes only comment was that the summer heat meant that operatives rotated the cutting times due to fatigue and heat exhaustion with having to wear all the heavy PPE.
The third tower situated in the redundant concrete panel plant at Kirkby in Ashfield, Nottinghamshire was demolished in September 2013. The 30metre tower this time was more straight forward, standing in the redundant 12 acre site the whole of which was to be demolished and the 1000 tons of scrap processed.
The method was standard and simple, Using a Komatsu 450 high reach the tower would be sheared to the ground. However, after eventually accessing the tower it became apparent that due to extensive vandalism parts of the structure would need to be done by remote demolition as they could fall in an uncontrolled manner. These parts were removed and the high reach could then do its work. Darren Sheldon, the Cawarden high reach driver, said it was ‘all in a day’s work’, ‘I love these challenging structures!’
DEMOLITION & DISMANTLING - APRIL 2014 51
HUGHES AND SCHOOL’S OUT! Demolition and Dismantling specialist Hughes and Salvidge has recently completed the demolition of a school in Southampton. Originally opened in 1982, Oaklands Community School was a mixed comprehensive school catering for 11 to 16 year olds.
Despite its excellent academic performance Oaklands was closed in 2008 and the building temporarily taken over by Oasis Academy Lord’s Hill, a school specialising in Arts with Business and Enterprise. In 2012 the Academy relocated to a purpose built facility with the original school building left vacant. The site was then sold for redevelopment subject to the demolition of the redundant school buildings with the exception of the disused community swimming pool
immediately adjacent to the structure.Hughes and Salvidge commenced the 14 week project by securing the site and soft-stripping the school’s internal fixtures and fittings.
Shortly after, work commenced on demolishing the southern portion of the school utilising a 25 tonne Hitachi excavator. Equipped with a pulveriser attachment, the Zaxis 250 made steady progress munching through the building section by section. Another Zaxis 250 was utilised on site for secondary demolition duties including segregating the various waste streams, stock piling material and loading separate hook bins with scrap and wood. Given the site’s location, this phase of the project presented several challenges as Martyn Burnett,
director of Hughes and Salvidge explains, The school was surrounded by residential dwellings and immediately adjacent to an Infant School and Nursery. Thanks to our ongoing investment in new plant and equipment we were able to deploy modern, low-emission excavators on the project including a new dash five Hitachi excavator which is very quiet and clean-burning. This machine is one of 5 new dash fives we have purchased and prove invaluable on sensitive projects like this one. “In addition to the modern plant, we were particularly rigorous in ensuring dust suppression was used throughout the demolition phase and also made use of access points furthest away from the school and nursery”.
D SALVIDGE Whilst conventional demolition techniques were deployed to dispatch a majority of the structure, a more delicate approach had to be taken by Hughes and Salvidge when demolishing the section of the condemned building which was directly connected to the swimming pool. “Although the school’s swimming pool was closed to the community in 2008, there are plans to re-open it as a community-run pool with the assistance of the local council. Because the swimming pool’s roof was supported in part by a wall that had to be demolished we had to install temporary support columns to prop the pools’ building whilst this could be carried out”. Because we are involved in processing demolition waste, namely scrap metal through our H and S Metals facility in Portsmouth
and concrete crushing at our K and B Crushing facility on Southampton Docks, we can ensure material is collected, transported and processed in a timely and environmentally sound manner. Martyn Burnett - Director of Hughes and Salvidge A minimum of 95% of all the material generated by the school’s demolition is expected to be recycled with a majority of the disposal carried out specialist sub-divisions of the Hughes and Salvidge business including H and S Metals and K and B crushing.
With the swimming pool secure and intact, and the rest of the site safely levelled, the local council is now in a position to re-develop the land and assist with providing the local community a much-needed recreational facility in the guise of a new reconditioned swimming pool.

TOTAL RECLAIMS T
WORKING WITH LIEBHERR he demise of the high-rise tower block has recently taken a step further in Nottingham with the demolition of one of a series of blocks by Total Reclaims Demolition.
The family owned company has been successful in winning the contract to demolish the four blocks of 1960’s towers situated in the Radford area of the city.
Constructed from a pre-cast panel design the towers are very weak in their construction having only a small amount of brackets holding the panels together. While many towers of this age are usually built around a solid lift shaft/stair core the Radford towers have a very weak central core. While making the demolition process somewhat easier in respects of the processing of the material, the initial demolition is made more complicated as the inherent weakness of the structure means that extra care and attention is needed during the project.
DEMOLITION Company Director and regular Liebherr operator, Gary Cross, explains that the panels need to be removed with great care as the poor construction technique means that as the building is demolished, any debris left on the floor panels and increasing the load upon them, has the potential to cause a collapse. “We have to be very careful to remove any materials lying on the slab as we are stepping the building back.” explains Mr Cross. Initially the company proceeded with the asbestos removal and soft strip of the seventeen story blocks whilst a temporary scaffold was being constructed to give access for the top down removal of the top five stories. Undertaken with Brokk demolition machines and a small skid steer loader the top stories were removed and work completed just prior to the Christmas break in 2013. Returning after Christmas to remove the scaffolding the company set about the remaining twelve stories with their latest purchase.
While the previous block of flats had been demolished using the company’s Komatsu PC450 high reach, a recent investment with ISP member Liebherr has seen the company take the third 34m reach R954VH-HDW to enter service in the UK.
We looked at other manufacturers before placing the order with Liebherr but the specification from them was ideal. Other manufacturers wanted to put this reach on a 70-80 tonne base machine which would make both operation and transport between jobs harder and more costlier than we could accept. Gary Cross Company Director
Voiced by many as “The Rolls Royce” of high reach machines, the new Liebherr is claimed by Total Reclaims as the perfect tool for the job. “Where many manufacturers list items as options, Liebherr supply them as standard.” states Mr Cross “Although this is reflected in the purchase price, it also means the
954 is designed as a high reach rather than just a conversion of a standard excavator.”
The machine is supplied with a heavy duty, variable width undercarriage enabling both easy transport and the ability to spread its weight over a significant area and increasing both the machines stability and working envelope.
While many manufacturers need to reduce the working radius of their equipment when working across the tracks, Liebherr’s LDC LIDAT system enables almost the full working range to be carried out at any radius and provides real time information on the machines inclination and tool positioning. Should the critical positioning be exceeded the LDC automatically activates the electronic reach limitation system. When this point is reached, the system ensures that no further movements of the equipment can be made so as to reduce the stability of the machine.
While the weight of the R954 has been increased form its standard 55 tonnes to a more portly 78 tonnes, the majority of the weight increase has been kept as low down as possible in the undercarriage and in the increased bulk of the counterweight. Weighing 14.5t the Liebherr is equipped with a removable 10.8t piece to allow for a reduction in transport weight should it be necessary. Spinning on a heavy duty slew ring from the material handling range of machinery, the R954 is powered by a very fuel efficient Liebherr D936 diesel engine. Delivering 326hp the engine is very rarely expected to reach its maximum 1800rpm as oil flow is the main requirement of
a machine of this type. The twin pump system installed on the Liebherr is capable of pumping hydraulic oil at a rate of 350 litres per minute to the tool, more than enough for the 2.5 tonne Indeco ILP850 that is being used on the end of the 11m dipper stick. Water suppression pipework has been fitted as standard to the machine enabling a mains connected hose to be coupled allowing a constant flow of water to keep airborne dust to a minimum. As the Liebherr will be used solely with the Indeco attachment when in high reach configuration, the attachment has been pinned directly to the dipper stick unlike the additional 5.5m digging
equipment that has also been supplied which has been fitted with a Miller quick hitch. This shorter equipment is variable in geometry enabling the company to operate the machine either as a 13m straight boom machine or as a 10m standard gooseneck. Both boom set-ups mean the machine is capable of carrying much heavier tools of up to 7 tonnes at 12m working height. The additional height afforded by the new machine also means that the company can make a cost saving on the top-down method by removing more floors with the excavator. Seen as a quicker, safer and more cost effective method, the team estimate that the remaining twelve stories will be down to the ground within seven to eight days.
As with most modern excavators, the Liebherr cab does not disappoint with Mr Cross being very complimentary about his new mount. “The cab is very comfortable and very quiet. The controls are very well laid out and the tilting function makes it much easier to see the tool.� While the Liebherr ticks all the boxes for Total Reclaims, there is one slight bugbear for Gary Cross.
The new machine is equipped with quick-couplings to all demolition boom hydraulic hoses enabling the boom to be theoretically changed in under an hour. Whilst this is true, the supports specified are stand alone items and require manhandling and fixing to the boom prior to it being removed. This is not the ideal solution for the Total Reclaims team and there is a thought that a purpose made cradle may be required to not only transport the booms between jobs but to decrease the time taken between attachment changeovers. The tower blocks are estimated to contain nine thousand tonnes of concrete that,once on the ground, will be processed on site and the resulting materials either reused for the future development of the site or sold on to other users. Once the towers are dropped and the arisings cleared, the site will be handed over to developers to construct a new development of low rise accommodation.

MCGEE GROUP BROADGATE CIRCLE W
orking in the City of London can be stressful at the best of times but one company, McGee, have built up an enviable reputation for successfully carrying out work in this demanding environment. While some jobs entail the complete demolition of a building, one of McGee’s recent contracts involved the partial demolition and alteration of a concrete framed structure with very limited access and surrounded by high profile neighbours.
The landmark Broadgate development in the heart of the City of London comprises world-class buildings, public art and vibrant landscaped open spaces. Since opening in 1991, the estate has been progressively evolving and now includes 16 separate buildings occupied by some of the world’s largest corporations. The office buildings are set around four landscaped squares each providing an attractive working environment surrounded by restaurants, pubs, shops and health clubs.
The surrounding buildings are occupied by prestigious companies including UBS, RBS, Deutsche Bank and EBRD and while these buildings remain in operation, the Landlord has employed Mace to undertake the construction of a new 111,500m2, multi-storey office development at number 5 which includes the re-development of the former skating rink that was situated in the centre of Broadgate Circle.
McGee won the contract to undertake the partial demolition and enabling works of the former skating rink in readiness for the on going construction works. Project Manager, Roy Pitchford, explained the project was demanding due to the logistical demands put upon the company by both the location and the neighbours and because of the care required in working in close proximity with live services.
The existing structure of the ice rink and arena was constructed from a reinforced concrete frame and housed retail units, restaurants and bars, in
its semi circular design. The five storey amphitheatre design contained three floors of retail units with the Basement containing plant rooms and a fifth tier situated above with planters housing a little bit of greenery in the city centre.
The original layout of the amphitheatre meant that there was a single storey level with the surrounding ground level, with a first floor level The raised arena floor was positioned between Lower Ground and Ground floor levels. Running below the lower retail area at Basement Level and providing service access to the whole of the Broadgate development sits a Gyratory roadway system, which carries all the services for the Broadgate Estate. Used for heavy goods vehicles making deliveries and housing all of the mechanical and electrical services to the buildings the Broadgate Gyratory gave McGee access to their portion of the works.
Even though the access was designed with goods vehicles in mind, 32t, eight wheelers were not at the forefront of the architects mind when it came to designing the access! As tight as it was the Gyratory still proved invaluable for the majority of plant and transport that needed to be sent onto the site. Working in such a busy area meant that McGee had to programme deliveries in sufficient time but constant communication and a sympathetic client meant that the overall movement of vehicles went relatively smoothly.
The initial task for the McGee team was the identification and isolation of services to the arena area. With banks of pipes and cables snaking their way around the walls of the Gyratory and being almost unmarked, the task of Isolating & cutting off the relative properties was made significantly harder. Allied to the fact that, the electricity supply to some of the large financial institutions in the area had to be kept intact at all times, most of the isolation tasks were carried out on evenings and weekends. With the relevant services identified and terminated, the soft strip and internal demolition work could be commenced.
The scope of McGee’s works involved not only the removal of the raised ice rink come arena floor and upper tiers of the amphitheatre but the removal of one and a half stories from the Rotunda building that overlooks the public plaza. The initial phase of the project involved the demolition of the raised arena floor. To undertake this task, McGee brought in a 20 tonne excavator equipped with a variety of hydraulic attachments. To ensure their neighbours were disrupted as little as possible, the majority of the heavy demolition works were carried out by a night shift with a day shift used to clean and clear the site. The arena floor was reduced to a suitable sized material to allow it to be formed into a ramp to allow the 20t excavator to track up and attack some of the higher elements that required removal. This was deemed to be a quicker and easier alternative to the use of handheld tools and micro excavators.
The concrete skeleton of the amphitheatre and stair tower has been clad with a Travertine decorative stone facade and the client had instructed that, during the partial demolition of the structure,
the stone facade panels were to be removed safely and stored for future use. With regard to the rotunda this in itself made the task of demolition slightly harder as the majority of the panels weighed in excess of 300kg and removing them facilitated the use of a mobile crane. With the arena floor removed and a the concrete floor cleaned and cleared of debris, a 30t all terrain crane was brought in to assist in the removal of the Upper elements and panels. Once the panels had been removed the rest of the demolition works could be commenced. For the Rotunda the use of a specialist spider crane was needed as some surrounding areas of the concourse were built on a suspended slab and whilst structural calculations had been supplied, the loadings available meant that McGee had to look at an alternative method of removing some of the panels. As the 30t all terrain crane could not be used, a smaller, 14t capacity spider crane was sourced. Ideally suited for the tight access and offering a reach and capacity within McGee’s needs, the spider crane proved to be a great help on the project.
With decorative panels removed and the main demolition works undertaken, attention was then turned to the removal of sections of the reinforced concrete slab to allow for future service and access routes through the new building. Several areas required temporary works Propping schemes of the slabs at 1st floor right through to the basement level were introduced to allow McGee to undertake the removal of various parts of the structure and cutting of slots of varying sizes. While the props were needed to stabilise the slab during the demolition phase, careful consideration had to be taken as to their positioning so as not to interfere with any of the future construction works. Once the slots had been cut and broken through onto full crash
decks, the ends of any rebar showing through were treated to stop corrosion taking place.
In some areas the existing rebar has been retained to allow for the tying in of new concrete structures to be installed by the main contractor. Unlike some of the service slots that could be cut as deep as possible, the areas that are getting adjoined to the new building needed great care when cutting through the concrete so as not to damage the rebar.
McGee removed a total of 5279.26 tonnes of material from site in skips and tippers with the height of demolition works seeing up to six 20 or 40m3 skips leaving the site on any one night. All materials moved off site have been logged using McGee’s innovative PodFather electronic data tagging system. Using a dedicated barcode sticker for the type of waste being moved, the company was able to keep tracks on exactly the amount of material moved from site at the touch of a button.
Once completed, Broadgate Circle will reopen as a much improved shopping and entertainment area for the many workers and visitors to this busy area of central London.
DEMOLITION & DISMANTLING - APRIL 2014 61
FORSHAW DE KOMATSU PC800-8 W
esthaughton based demolition contractors Forshaw Demolition have recently purchased the tallest and heaviest high reach excavator, a Komatsu PC800-8, to enter their fleet and have set it to work completing one of the largest demolition projects undertaken in Manchester for a number of years.
The Chatsworth estate in Gorton, East Manchester is undergoing a massive regeneration programme including the demolition of a large quantity of council owned properties and what was once the set of Channel 4 popular TV series, Shameless. The majority of properties found on the estate were of traditional brick and block with a pitched, concrete tiled roof
construction. Comprising of two, three and four storey buildings the estate had been earmarked for demolition but as of yet, no firm plans had been put in place to redevelop the site once demolition has been completed.
Forshaw’s won the contract to demolish the properties from main contractor Balfour Beatty (previously Mansell) and commenced working on site in February 2013 on Phase 1, a £1.5m contract for the clearance of the 2,3 and 4 storey maisonettes. While the staff employed by the main contractor had some experience in demolition, Forshaw were asked to use their vast knowledge to ensure the contract was undertaken and completed professionally and safely.
Once the residents had been moved to new locations and the services to the buildings had been disconnected Forshaw quickly moved in to remove asbestos and remove any materials that could be recycled. With the buildings cleaned and cleared out, the quickest and most economical way of demolition was the use of a number of selector grab equipped Doosan excavators, and the 4 storey flats utilising an Hitachi Zaxis 470 LCH demolition specification high reach excavator supplied new in April 2013 by HM Plant and Kocurek.
Carefully removing timber floor trusses, doors and floors, the materials were all segregated for further recycling off site. Masonry arising from the demolition, including all of the slabs and footings, were removed with a number of 35 tonne Doosan DX340’s and with the material being transported off site to be crushed, screened and sold on for reuse as a site engineering aggregate. With the smaller properties demolished, Forshaw were then required to fence the areas off, top soil and seed as part of their contract.
While the company’s demolition specification Doosan excavators have successfully demolished the smaller buildings, Phase 2 of the contract is a £1.2m project invoicing the demolition of a pair of 16 storey tower blocks; this is where the company’s new purchase came into play. Constructed around a central reinforced concrete core, the tower blocks were situated adjacent to each other on the same piece of land.
The initial phase of the tower block demolition, as with the smaller properties, involved the soft strip of all materials. Using the lift shafts as a rubble chute the arisings were then removed with a small Bobcat skid steer loader before being loaded into bulk skips by one of Forshaw’s Doosan DX140 excavators. Based on an 80 tonne standard machine, the Komatsu was sent to Ipswich specialists Kocurek to undergo their expert attention by the original purchaser. The Komatsu underwent the typical Kocurek conversion into a telescopic high reach machine taking its weight to over 100 tonnes. Not only did it benefit from the addition of a telescopic boom capable of carrying a 2.5 tonne tool
EMOLITION to a height of 44m with Kocurek’s modular joint but, as with the majority of demolition conversions undertaken by Kocurek, included the lengthening of the original track frames and the addition of a hydraulically controlled, variable width undercarriage to keep the machine stable and firmly planted to the ground when operating at full reach.
Additionally, Kocurek increased the mass of the counterweight to aid in the machine’s stability. While the Komatsu was purchased specifically with this project in mind, it was also an opportunity for the company to increase their presence in the high reach market and ensure more projects are undertaken totally in-house. The added height afforded by the new Komatsu also meant that a raised working platform was not required to be constructed to undertake the demolition of the flats. Forshaw also engaged Kocurek to manufacture a longer dipper arm for the machine to give it a reach of 47m when fully extended.
Capable of operating at a maximum of 47m, with its additional boom extension and longer dipper, the Komatsu has come to Forshaw with an additional short boom option enabling the machine to be used on a variety of contracts. The additional “standard’ digging equipment means that the machine can be utilised for a wider variety of contracts and also means that heavier tools may be used further increasing the new purchases flexibilty. The boom is manufactured from high quality, lightweight steel and incorporates three telescoping sections. Similar to crane technology, the three boom sections extend simultaneously and lock into predetermined positions to give the Komatsu its maximum working height. The Komatsu is fitted with pipework to facilitate the use of the on-board dust suppression system and while the system will be used in Gorton, separateturbine systems have also been utilised from European Attachments Group.
While the 47m reach of the fleets new addition may be impressive, it would mean nothing with out an effective tool on the end of the dipper. The Komatsu has been fitted with a new Rotar RDC20 processor supplied by another ISP member, Worsley Plant.
Weighing in at 1.8t, the RDC20 is well within the PC800’s lift capabilities yet is more than a match for the precast concrete panels on the flats. With a cutting force of 78t on the tip the RDC20 offers a very quick closing speed of 1.2 seconds enabling the operator, John Sharples to quickly and effectively reduce the building to rubble.
Following the completion of the Manchester contract in April 2014, the machine moves to the Gascoigne Estate, London Borough of Barking and Dagenham for a 13 storey block demolition and then back up to Salford for the demolition of 3, 17 storey blocks for the City of Salford and Salix Homes.
DEMOLITION & DISMANTLING - APRIL 2014 63
ERITH GROUP INNER CITY LIMITS P
rinciple Contractor Erith have started works on their project Oriana 2. This is a complex project that involves the demolition of 26 – 48 Oxford Street and 55 Hanway Street with the façade retention of a number of buildings. Oriana 2 is located to the east end of Oxford Street adjacent to Tottenham Court Road and is an extension of the original Oriana 1 which was developed around two years ago and where Primark have their flagship store.
The works at Oriana 2 commenced on the 30th September 2013 for a contract period of 40 weeks with the works due to be completed in July 2014 and is split into Phase 1 and 2 based on the staggered Vacant Possession dates of the various buildings. Oriana 2 is a complex project which involves the demolition of 26 – 48 Oxford Street and 55 Hanway Street with the façade retention of a number of buildings.
The existing buildings are a mixture of architectural styles varying in age from a 19th Century bay window four-storey building with an original butterfly roof to the ‘newest’ building built in the 1960’s. 26-32 Oxford Street, although redeveloped in 1955 with a green panelled curtain walled building was previously the famous Frascati restaurant and before that an 18th century brewery site, many of the original Frascati features are still visible as the soft stripping removes the more recent refurbishments. This building is to be demolished adjacent to and over the live Primark building; therefore temporary works will be installed to ensure Primark is not disturbed. The works comprise of investigation works to formulate a detailed temporary works scheme, asbestos Surveys plus removal, removal of redundant building services, protection of basement sub-stations and the construction of a UKPN diversion beneath the level of the building basements.
Over the years the buildings, due to their age, have received a multitude of alterations and extensions, much of which is not fully known until full investigations and soft stripping is carried out, versatile and quick variations, often requiring a design change are having to made on a regular basis, often we are surprised to find old fireplaces that have been hidden for years behind refurbishment.
All materials arising from the works are recycled except for asbestos, any asbestos identified on site are removed prior to demolition and removed from site by fully licenced contractors. All of the temporary works are contractor designed with Erith utilising their internal design company, Swanton Consulting, for all design matters.
Logistically, this site was always going to be challenging, with its location between the ever-busy Oxford Street, probably the busiest shopping street in the world and Hanway Street, which seems to the narrowest. With these close quarters, Erith have maintained a close co-ordination with the noise team and licencing Team at Westminster City Council. They have maintained an openness and honesty with the neighbourhood with residents being kept informed by the publication and distribution of regular newsletters. With this, Residents are encouraged to provide feedback and to date, Erith have not yet received a single complaint. Weekly monitoring is carried out on noise, dust and vibration in addition to tower crane base and façade monitoring.
Back-propping to the floors is placed throughout the buildings prior to the Demolition being carried out with a combination of 3 tonne mini excavators and hand tools, at the lower levels work have been carried out with a 13 Tonne excavator with all materials separated and sorted into streams for recycling and re-use.

KDC REMOVING D K
DC contractors based in Manchester are currently one of the few NFDC members to operate abroad on a regular basis. The company are undertaking a project for Dow Chemicals in Tessenderlo, to the North East of Belgium, involving the decommissioning and demolition of a former chemical production plant.Situated on the banks of the Albert canal the plant had been used to manufacture HDPE, but due to increased power and manufacturing costs manufacturing of this type is commonly now undertaken in the Middle East and USA.
The demolition of the redundant plant was put out to competitive tender with both European and UK based contractors submitting their tenders.
As a regular contractor for Dow, KDC won the competitive bid on cost and their outstanding knowledge and health and safety record which had been demonstrated on similar projects. While the project was to remove the DOW HDPE plant in its entirety, work was also undertaken to the adjacent Styron operated Styrene plant which was still live and in production 24/7.
These services were removed thanks to the careful and considered organisation from the KDC team.
DOW HDPE PLANT “With disruption to the live Styron plant kept to an absolute minimum.” explained Contracts Manager Paul Williams.
With the services disconnected and the site now isolated the company then set about the removal and disposal of the nominal amount of asbestos encountered on site. As with most industrial production plants, KDC are encountering a wide variety of structures and materials on the 80,000m2 site during the 18 week contract. Large storage tanks, production plant, administration buildings, extruder and catalyst plants, many 35m high silos and 50m column & flare stack that dominated the site along with masses of pipe runs.
With the asbestos now removed from the site, the company have commenced on the demolition of the buildings & structures. The majority of the equipment involved in the demolition process was taken from the extensive UK based fleet. Employing the services of their Hitachi Zaxis 670 fitted with both standard and high reach equipment, KDC are able to tackle all but the 50m column and flare which will be collapsed using a cut and pull technique.
A pair of Komatsu PC450 excavators in standard guise, along with a pair of Caterpillar M322 wheeled excavators were also dispatched from the UK. “It was more cost effective for us to send our own equipment over to complete the project” explains Mr Williams “Our Site Manager on the project, Darrell Coleman, was then able to supplement the fleet with smaller locally sourced plant and access equipment as and when necessary”
to facilitate the health and safety remit on the project. Even though the language barrier in the Benelux region is not as prevalent as in some parts of Europe, the local Health and Safety representative also acts as a translator should the need arise. The majority of structures are being dismantled using shear attachments on the fleet of excavators with the arising metals sorted for recycling. The company are however encountering some particularly heavy gauge stainless steel in the plant’s driers and reactors which are up to 200mm thick.
The team have approached the cutting of these driers and reactors differently to that of the rest of the plant. These materials are too dense for the shears to cope with so the company utilised a powder burning method to slice the items into manageable pieces.
The Caterpillar M322 excavators are used to sort the materials and load into road going vehicles for their transportation to recycling facilities in Holland and Germany. The carbon steel is recycled in Holland, Aluminium in Germany
and Copper and Stainless Steel materials are shipped back to the UK as the company are able to realise a better financial return for them even with the associated shipping costs.
We looked at the possibility of utilising the Albert Canal to transport the materials from the site, but the lack of a suitable quayside to facilitate the loading prohibited us from taking up this method.Paul Williams - Contracts Manager
With approximately six thousand tonnes of metals to be recovered and recycled from the demolition process, KDC will leave the site graded level in readiness for any future development of the land.
Looking to future contracts, the KDC management team have not ruled out looking at further foreign projects should the opportunities arise. “We have undertaken previous projects in mainland Europe and the Channel & Shetland Islands.” commented Mr Williams.
KDC are employing 12 of their own staff & personnel on the project and with the safe and sustainable delivery of operations being the core principle at KDC, the services of a local consultant are being used DEMOLITION & DISMANTLING - APRIL 2014 69
INSTITUTE OF DEMOLITION ENGINEERS Another well organised Spring
Seminar for the Institute of Demolition Engineers saw a large turn out of members and exhibitors. An informative mix of seminars and speeches captivated audiences throughout the day.
On Friday 28th February the Institute of Demolition Engineers held their Spring Seminar at The Royal Armouries, Leeds. As always the event was very well supported with nearly 200 delegates, there were 15 exhibitors’ stands in the main hall where coffee and lunch were provided and once again they said that they benefitted from attending.
The first morning session started with Simon Davies, the General Manager of Violia Environmental Services, who gave a presentation about the removal of oil and gas platforms and structures in the North Sea. He was followed by Stuart Vincent, a Specialist Solicitor with S V Armstrong, who defends individuals and companies in civil appeals and other regulatory proceedings. His presentation about legal challenges to the HSE encouraged some very
interesting debate on the subject. The second morning session was lead off by Ian Wharton from RVA speaking about the problems of carrying out demolition projects abroad. Wayne Bagnall, who is an independent consultant and gives specialist safety advice and training in asbestos and demolition, then spoke about two projects, the main one being the dismantling of two travelling dockside cranes at Salford Docks.
The session was concluded by a young man, Stephen Sutton, who had been diagnosed with terminal cancer at the age of fifteen. He spoke about his positive lifestyle living for today when you never know when it might end and how he had put together a bucket list that he was trying to work through, he was a true inspiration to us all.
The afternoon session commenced with a presentation from Peter Baldwin who is a Senior Hygienist with the Health and Safety Laboratory, speaking about surveys that have been carried out about asbestos and silica related diseases.
70 DEMOLITION & DISMANTLING - APRIL 2014
Then Philip Baker, Managing Director of BPS Solutions, gave an update on the proposed revisions to the CDM Regulations which produced some lengthy discussions. The final presentation was given by Steve Jack from Magnox Ltd, outlining the process they adopt for managing the decommissioning of Nuclear Power Stations using Framework Contractors. The Institute of Demolition Engineers will be holding a number of regional meetings in all areas in the next three months, and have their Autumn Seminar at One Great George Street in London on 26th September followed by the AGM at the Tower of London on 14th November.

THE BIG INTE SIMULATOR PROGRESS D
emolition & Dismantling Magazine talks to NFDC CEO Howard Button and Group Manager Sophie Cox about the world’s first demolition plant simulator and its future in the industry.
D&D: The big news for the last year in terms of operator training is the release of the world’s first demolition plant simulator. Can you enlighten us on this? SC: The simulator has been with us since its launch at the Demolition Expo in June last year and we have now offered the Two Day Foundation Demolition Plant Course to over 20 candidates with a 50% match grant available to employers on completion. The simulator is aimed primarily at new operators, or those progressing from a standard excavator 360 into the demolition discipline.
try and get them to agree that the simulator provides a foundation in the operation of demolition plant equipment and that will enable the operator to go on site and train in a real life situation. We are the most progressive industry out there for training and we can hopefully get the CPCS to agree that he simulator provides a trainee with the core skills necessary. If the CPCS are able to endorse a certificate it will be a step in the right direction. D&D: Would offering it as a training aid to the wider industry be a thought? SC: We are also looking at marketing opportunities to place the simulator into general
D&D: Will a course on the simulator get an operative a card entitling them to go onto site as a machine operator? SC: We have been asked that but it is solely designed for novices with no machine experience or operators coming from a construction background. It will give employers the opportunity to see if a trainee is capable of stepping up to the real machine. The Foundation Training Course developed around the simulator is a two day programme with a full day of Demolition Plant Awareness, followed by a day on the simulator. On completion of the course, candidates are prepared with the basic knowledge and understanding of skills required to operate the machine in a real life environment and are issued an NDTG certificate. HB: CPCS have been in and looked at the simulator. Our next step is to 72 DEMOLITION & DISMANTLING - APRIL 2014
construction situations as the software comes pre-loaded with general applications. We would like to keep it special and solely for the demolition industry but by sending it out to the construction sector it also raises the profile and speciality of the demolition industry.
D&D: Will you be attending trade shows and conferences to show case the kit? HB: We recently attended the DA Conference in Berlin and the Demolition Convention in Las Vegas, both at the invitation of the relevant trade associations. They fully funded the whole trip as they can see the benefits for their workforce by adopting a similar approach and as the NFDC we will
ERVIEW always support the growth of the whole industry, both in the UK and Worldwide. Furthermore, the NDTG was invited to showcase the simulator at Skills Show towards the end of last year to support CITB. The simulator was inundated with keen and enthusiastic children and school leavers and it gave the NDTG a great opportunity to promote the industry as a positive and skilled career path. We will continue to attend events of this nature.
D&D: What other opportunities are there for members and trainees to make use of this innovative piece of kit? SC: We have received enquiries from companies looking to hire it from us to undertake in-house training and we can offer this at competitive prices. We will always hire it out with one of our qualified trainers for their bespoke training requirements. It can even be hired out for team building days within
firms or to as a promotional tool at trade shows.
D&D: You purchased two simulators last year. Where are they positioned? HB: We have one unit positioned at the NDTG Training Centre in Hemel Hempstead, and the other one positioned in Glasgow at the NDTG (Scotland) facility. Our members, North of the Border are now able to train operators and utilise its capabilities. SC: The simulators are mobile though. We have just purchased a trailer for its road trips and we are looking at new ways of getting it out to the wider market without having to constantly bring trainees down to Hemel. D&D: What are the next steps for the Simulator? SC: We are already looking into Phase 2 of the project, with the possibility to develop software to up-skill existing standards
demolition plant operators to high reach operators. For now though, we are satisfied that this huge leap into new technology has a wealth of benefits for the sector and although we are only in the first 12 months of its release, we are confident that we have taken the best approach to foundation training. At this point, we encourage all companies to consider how the simulator can help them progress their workforce.

HIGH STABILITY DEMOLITION ROBOT
T
he new Husqvarna DXR 300 is a powerful addition to Husqvarna’s range of remote demolition robots. With 22 kW, the robust DXR 300 offers efficient demolition in tough environments. Not least because of the new outriggers that deliver superior stability and has the ability to carry more than 400 kg of workload.
By launching DXR 300, Husqvarna has taken a big step towards offering their customers a complete series of remote demolition robots. “We can now offer customers robots in the 1,000–2,000 kg range,” says Lars Gustafsson, Global Product Manager, Husqvarna Construction.
Husqvarna DXR 300 is equipped with the new out-riggers, which will be a standard feature on DXR 270, DXR 300 and DXR 310 from 2013. The new out-riggers are 160 mm wider than the existing setup, which means they will provide increased robot stability and have the ability to carry more than 400 kg of workload. Nevertheless, DXR 300 weighs only 1,960 kg, which makes it the lightest remote demolition robot in its segment.
The user’s perspective DXR 300 is equipped with a fixed arm that delivers precise positioning of the tool and requires only a minimum of service. With a full reach of 5.2 metres, it is ideal for demolition of concrete and brick constructions, staircases, roofs and balconies as well as sensitive locations such as courtyards.
Adopting the customer’s perspective in the product development means considering all aspects of the user’s prerequisites. DXR 300 is designed with this in mind.
“DXR 300 is only 78 cm wide. That means it will fit through most doorways and construction lifts, making it suitable for diverse applications within the construction area,” says Lars Gustafsson. The remote control with a 3½ inch colour display and Bluetooth technology is made to facilitate one-handed operations and to make the daily work easier for the user. The control system is adapted to handle conventional demolition environments with high vibrations, concrete dust and water.
74 DEMOLITION & DISMANTLING - APRIL 2014
It also provides an element of safety as the operator can stand at a comfortable distance from the machine while working.
TECHNICAL SPECIFICATIONS • Power: 22 kW
• Weight: 1,960 kg
• Reach: 5,2 metres
• Control system is modular, digital CAN-based PLC
• Automatic breaker lubrication is included in standard version
ECY HAULMARK FLEET WITH OILQUICK E
CY Haulmark have recently completed a deal with Irlam based Federation member Northbank Demolition to supply the final machines in their fleet with the OilQuick system. The company have been using the OilQuick system on their fleet of Caterpillar, Doosan and Hitachi excavators for a couple of years with great success and now boast a full fleet of OilQuick equipped excavators.
With excavators ranging from 7.5 tonne through to 60 tonne the use of the OilQuick system has increased the versatility of the fleet making operations simpler, quicker and safer. “There is no need for the driver to get out of the cab and try and change hoses now.” explains Northbank MD Paul Richards. “There is no loss of hydraulic oil and the attachments are changed within seconds making our productivity better.”
The latest order placed with Warrington based ECY Haulmark is to be fitted to the newest excavator to join the fleet, a 26m high reach Doosan DX420. Purchased to service the increasing workload for Northbank the new Doosan has been put to work in Edmonton, North London to service a contract for a Blue Chip client.
With their latest purchase completing the fleets conversion, Northbank now operate one of the largest OilQuick equipped demolition fleets in the UK. “Since we put the first units into operation we have experienced less downtime due to hose bursts and are pleased with the simplicity and quality of the coupler” commented Mr Richards “The sales and service back up we have from ECY is first class too.”
Northbank also operate a full range of hydraulic demolition attachments from ECY Haulmark and are particularly happy with the power, quality and reliability from the VTN range of attachments.
The OilQuick system is available exclusively from ECY Haulmark and is suitable for excavators ranging from 2.5 tonne through to 120 tonne.
