Dear Readers Welcome to our September edition. This is the last edition in the current form. From now on we will be issuing IBB BUILDER weekly blog posts and newsletters. Our readers can subscribe to newsletters via their online account at www.ibb.uk. Thank you for choosing IBB Builder as your source of industry news and technology insights. Follow us on social media to stay up to date with monthly deals and exclusive offers. We hope you will stay with us. Coming back to this edition, I would like to introduce you to the technology section. Most of you just came back from holidays, and with autumn around the corner, all outside work will be in full speed now to be finished before raining season commence. The cover story of this issue relates to the roofing works. Check out the guidance on the pitched roof construction. From proper materials selection to tips on building a structure, with all these, you can be sure to finish your roof project on time and to the highest standard. September is also a great time for house extensions. Check out our article “Conversion that is like an extension” for the advice on building regs and planning permission, types of conversions and its step by step building. The conversion is cheaper to build than extension but still offers immaculate design features and adds value to a house. Moreover, our technology section this month features the guidance to plumbing. Materials comparison and tips on use. Our September monthly deals include products designated for all these plumbing works. On next pages, you will get a little remainder of two “must-attend” events for the construction sector. Register now to get your free entry to UK Construction Week 2018 in NEC Birmingham and London Build 2018 in Olympia London. Both events are happening in October. Do not miss great networking opportunities and visit IBB Builders Merchants stand. The digitalisation of the industry is progressing and revolutionising the method of construction. Inside this edition, you will find the interesting article on bricklaying robots. Some view new technology as the reason for job losses in building trades. However, recent figures show that employers have troubles in finding bricklayers and plasterers due to skills shortages and the fact that young people still prefer studies at universities over career in the construction.
Both bricklaying and plastering are vital in delivering new homes as per Government housing strategy and here come construction robots. When it comes to builders’ education, The Department for Education has recently announced that the teaching of T Levels for construction will commence in September 2020. The alternative to A Levels is designed to encourage new entrants into the industry. The construction sector is one of the most profitable, but stereotypes keep young people on distance. T Levels should work as an incentive for new entrants to the industry. Check inside for more about this topic and other great courses for construction workers including scaffolders trailblazer. With Brexit around the corner, we are checking how is our industry reacting to the possible no deal exit from the EU. In the article about the construction sector in London, you will get the latest facts on builders’ situation in the capital. Both EU workers and British builders hope for the best outcome from negotiations. We wish the best to the UK and our industry. With regards to our sponsorship activities, we are continuing our partnership with IBB Polonia London VC. Check out their plans for this season. IBB Polonia London FC is recruiting new members.

CONSTRUCTION NEWS
Robots will build our future homes. The construction industry is suffering from a small number of new entrants wishing to pursue their careers in this sector. The population is growing and so the demand for new houses. The construction worldwide employs only 8% of the population. Currently, the skills shortages are influencing the supply of new homes.
There is an urgent need to find the solution that will secure the sector growth. With the development of new technologies, there is the chance that the shortage of skilled bricklayers will be replaced by robots like Hadrian X or Sam 100 and others. Top construction companies will use robots to meet the demand. Amongst the recent innovation in this field, Australia’s Fastbrick Robotics introduced to the industry Bob, the Builder. This new bricklaying machine can build a house four times faster than human workers. It is not only extremely efficient but also accurate. Bricklaying robot Hadrian 105 automates the job of laying bricks and is capable of finishing brickwork on the house in few days at a lower cost and a higher quality than in the standard way.
6
Currently, there is the new prototype in the making called Hadrian X which will be bigger and faster. Hadrian X will be able to lay 1000 bricks per hour as compared to the previous model doing 225 blocks per hour. Moreover, it can handle various types of blocks and can cut, grind, mill and route them to fit the structure before laying down. Instead of mortar, this machine uses adhesives and interlocking system. The robot can be mounted on the track for easy transport between building sites. After installation on the site, the bricks are lifted off a pack and placed onto a shuttle that gets them ready for cutting, drilling or laying. Laser tracker and sensors guide the brick laying process. The bricklaying machine can be programmed to make room for doors, windows, pipes etc. Hadrian X is the first globally patented bricklaying robot. The Australian company has developed the world’s most advanced construction robot. Fastbrick’s Hadrian X will commence working in Q3 this year in Mexico as a part of testing. It is the first time that the construction robot is being deployed in the different country. Mexico suffers from a housing crisis and environmental catastrophes. Its low-rise construction consists of mainly brick and block construction. There is also a lack of skilled construction workers. All these factors are an advantage for Hadrian X robots that might in the future replace bricklaying labour in Mexico.
CONSTRUCTION NEWS
100, is currently deployed on some building sites. It lays bricks every 8.5 seconds and beat human bricklayers who manage to put 300-600 blocks in 8 hours. Sam works collaboratively with the mason, who has to set up the robotic builder, supervise health and safety and assist with the bricklaying process. However, introducing SAM 100 allows cutting workers cost by at least 50%. Construction Robotics that developed SAM 100 is planning to introduce bricklaying robots to Britains construction sector. Some are worried that the automation of the
bricklaying industry will result in mass layoffs. Bricklayers have been laying bricks and blocks in the same manner for years now, and it is the highest time to innovate this building process. The recent involvement of robots in the bricklaying jobs shows that it is more difficult for a machine to build the smaller structure so probably residential houses will be manufactured in the factories while low rise and high rise buildings could benefit from construction robots. Hopefully, the digitalisation and advanced technology will help to bring the new generation of workers into the industry. Source: www.fbr.com.au www.construction-robotics.com

The CEO of Fastbrick, Mike Pivac commented: “The Hadrian X presents a solution to Mexico’s acute shortage of well-constructed affordable homes, with access to the necessary services like schools, parks and commercial areas.” He added that “GP Vivienda is an ideal partner for FBR in Mexico, as they have shown they are adaptable and willing to embrace disruptive technology and have sufficient scale to offer an excellent proving ground for the Hadrian X and future DST applications in North America.” In the US, the semi-automated mason SAM

Forecast
for London construction
The construction industry has suffered from the uncertainty due to Brexit negotiations what is influencing investors’ planning ahead. Moreover, the liquidation of the construction giant Carillion at the beginning of this year impacted workers, building businesses and the whole market. The productivity is the primary challenge for the industry, but the weaker pound is also putting the impact on the cost of materials as approximately 65% of construction materials are imported. Building costs are set to rise by 4 per cent annually to 2021. 8
CONSTRUCTION NEWS
Predictions are that when the Brexit deal is made, investors will release funds and go ahead with postponed projects. In London projects connected with new builds are set to perform better than residential refurbishments. In current economic and political circumstances, the constant re-assessments of the condition of the industry is required to inform businesses about levels of demand, project feasibility, any possible cost pressure, etc. However, according to the recent surveys, there are no signs of problems for the construction industry in the London as indicators show the London builders performed very well in the second quarter of 2018. The Federation of Master Builders’s (FMB) survey called the “State of Trade Survey” that assess the UK’s SME construction sector gave the positive results like for instance, the recorded rise in optimism among London’s builders: • increase in the workloads, enquiries and expected projects rose by 2 per cent • 89% reported increasing material prices • 65% is struggling to hire bricklayers, and 60% are struggling to hire carpenters Barry Mortimer, Director of FMB London, said: “London’s builders enjoyed rising workloads in the second quarter of this year and are also optimistic about the coming months. While sustained growth and this slight increase in activity are very
welcome signs, any optimism should be tempered by the sharp rises seen in the number of firms reporting that they are struggling to hire bricklayers, carpenters and plasterers. London’s SME builders, as well as protecting themselves from sunburn, are scrambling to protect themselves from rising skills shortages. Having to turn away work due to a lack of staff is heart-breaking for small business owners, but this is the situation for many of the capital’s construction SMEs.” Mortimer continued: “On top of the significant constraints that lack of skilled workers imposes, Brexit worries and concerns are reaching a crescendo. The FMB’s recent call for clarity on postBrexit visa rules is critical. London’s construction industry has leant heavily on skilled EU workers for some years now. Indeed, one in three of the capital’s construction workers is from the EU. An exodus of these workers, or any cliff-edge in terms of access to European workers, could hit the capital’s housing and infrastructure projects very hard indeed.” Mortimer concluded: “As well as providing the certainty and stability which London businesses are craving for, the Government needs to take into account the needs of key industries like ours in deciding their post-Brexit approach to migration. It is vital to the London economy that its construction sector remains on the sunny uplands
and retaining access to skilled migrant labour will be crucial to achieving this.” According to the Construction Industry Training Board (CITB), over 150,00 construction jobs are predicted to be created over the next five years despite Brexit uncertainty. Approximately over 15,000 carpenters and almost 10,000 labourers will be needed as homebuilding ramps up. CITB Policy Director Steve Radley said: “Despite all the gloom around Carillion and uncertainty from Brexit, our report’s message is that construction will continue to grow and create more jobs. “Though growth is slightly down on 2017, it’s looking more balanced with housing and infrastructure both expanding significantly. And the range of job opportunities is growing. While we need to bring in lots of people in the trades, the fastest growth will be for professionals at 7.8% and for managers and supervisors at 5.6%. “By 2022, employment will be in touching distance of the heady 2008 peak, so we face a massive recruitment and training challenge, which is likely to get harder after Brexit. So while we can take some comfort from weathering the recent storms, it’s vital that we make the investment in skills today that will shape our own destiny for tomorrow.” (Source: FMB, CITB)

T-Levels for Construction The Department for Education has recently announced that teaching of T Levels for construction will commence in September 2020. T Levels will be an alternative to A Levels but for practically minded students.
T Levels is the technical programme that will last 2 years. It is designed with employers to ensure new entrants into the industry will be equipped with the excellent skills. Students aged 16 to 18 will have a technical alternative to A Levels. T Levels will provide a mixture of: • technical knowledge and practical skills specific to their chosen industry or occupation • an industry placement of at least 45 days in their chosen industry or occupation • relevant maths, English and digital skills • common workplace skills The programme of T Levels will be developed by industry professionals and employers, including for instance experts from companies like EDF, Lloyds, Skanska, Morphy Richards and many more. Students who achieve a T Level will get a certificate recognised nationally by employers which will set out what they have achieved as part of the programme. Apart of construction industry T Levels will be available for instance in the following industries: digital, education, engineering, health and science, legal, creative and design, etc.
On the completion of the T Levels students will be able to move into: • a skilled occupation • higher or degree level apprenticeships • higher level technical study, including higher education T Levels might address the construction industry skills gap and ensures its competitiveness. Together with the reform of the apprenticeship levy it will offer the better incentive for young people to choose the career in construction. In May, the Education Secretary, Damian Hinds has named 52 colleges and post-16 providers to teach the new T Levels. Mr Hinds said: “T Levels provide a highquality, technical alternative to A levels ensuring thousands of people across the country have the skills we need to compete globally – a vital part of our modern industrial strategy,” However, the Federation of Master Builders has warned to government to be more realistic about the T Levels in construction industry. Brian Berry, Chief Executive of the FMB, said: “The idea that a student who has completed a T Level in bricklaying is able to call themselves a qualified bricklayer is not credible. The Government must be realistic about how much can be achieved in two years of largely college-based learning. Although T Levels include a three-month work placement, when the rest of the individual’s knowledge and skills are acquired in the classroom, in construction they will need more time onsite, post-T Level, before they can and should describe themselves as being qualified in that trade. Small and medium-sized construction firms, which do the bulk of training in our industry, would rather
view T Levels as a rich pool of talent through which to find apprentices.” Berry continued: “More positively, the Government has listened to the concerns of the construction industry and stated its intention to make work placements as flexible as possible. In construction, work placements are not popular or common so persuading sufficient numbers of employers to offer these opportunities will be challenging. The Government being open to the three-month placement being achieved through more than one employer is therefore vital. However, to ensure work placements are as attractive as possible, the Construction Industry Training Board (CITB) should consider offering financial incentives to employers through CITB Grant. We know, for example, that a typical construction SME is likely to shell out an additional £500 for their Employers’ Liability insurance because of having a young person onsite for three months. This is on top of the resource needed to closely supervise that young person. If employers can be financially incentivised somehow, it would be helpful.” Berry concluded: “If implemented properly, T Levels have the potential to provide parity of esteem between vocational and academic education. Although there are challenges regarding the implementation of T Levels, we are committed to working with the Government constructively to overcome those challenges. If the UK is to increase its productivity, we need more young people, and their parents and teachers, to recognise the value of a career in construction. With Brexit just around the corner, this has never been so important.”

Scaffolding
Trailblazer
Scaffolding Trailblazer programme will start on 1st October to train the next generation of scaffolding apprentices. This course is launched by the Institute for apprenticeships, and it will replace the current framework. All applicants registered on the current system before the introduction of the Trailblazer will have two years to complete their training. The Government established the Trailblazer initiative as part of a significant reform of apprenticeship training in England. The Scaffolding Trailblazer standard was developed by a committee comprising representatives from around 15 scaffolding contractors and supplemented by Institute of apprenticeship staff, CISRS, CITB and two approved training providers. Dave Francis, Scaffolding Trailblazer Committee Chair, said: “The Trailblazer initiative has
16
allowed us to complete a full review of the apprenticeship programme. Industry experts have worked together to set the standards for all interested to develop their careers in the construction sector through a Trailblazer apprenticeship. “Employers have the ability to directly control their employee's training, with the knowledge that they are participating in a standardised apprenticeship programme with full quality assessment, delivering the workforce that industry requires.”
On the course completion, the scaffolder will have the relevant knowledge on scaffolds errection, structure, methods of attachment, protection, safety and more. The scaffolder will be able to make adequate safety procedures, assemble and install scaffold materials, inspect scaffolding, etc. More details on the course you will find at www.instituteforapprenticeships.org/apprenticeship-standards/scaffolder Source: NASC

Waste Management Plan
18
BUILDERS EDUCATION
Reducing and recycling the construction waste can generate an additional income, reduce the costs of purchasing more materials, increase skip space, comply with legislation, reduce CO2 emissions, etc. All businesses have to ensure the waste they produce is handled safely and legally. It is the responsibility of the contractor to check if the company removing debris from the building site is a registered waste carrier. Use the Waste Directory Website (www.wastedirectory.org.uk) to find the registered carrier. A Waste Transfer Note must accompany every load of waste that leaves your site. This provides an accurate description of the waste to enable it to be treated safely. You must keep copies of all waste transfer notes for at least two years. Follow this steps for the efficient site waste management: • arrange deliveries at various work stages to avoid storage on site • avoid over-ordering • reduce the amount of defective work • never accept poor quality materials • buy sand and sharp in bulk bags to reduce wastage • encourage workers to join the waste management on site by offering them bonuses • return or donate unused materials or left overs • use recycled materials • sort waste for recycling • repair pallets for reuse • use the insulation cut offs • sort plastic packaging • sort timber, cardboard and rubble • invest in a mini crusher-screener to process old bricks, blocks or concrete into recycle aggregate for new projects
A Site Waste Management Plan (SWMP) is a legal requirement in England for projects over £300,000. It requires the contractor to forecast and record waste and how it is managed. SWMP may still be required for BREEAM assessments or by the local planning authority. Local planning authority might request a SWMP as the part of planning process. Using the SWMP will help the to: • increase profit margins • reduce waste costs • stay compliant with the legal obligations • decrease amount of waste What is a SWMP? It sets out how waste resources can be managed at all stages of a building project. This document states who is responsible for waste management, what types of waste will be generated, how the waste will be managed, which contractors will be legally responsible for waste disposal, how the waste quantity will be measured, etc. The Department for Environment, Food and Rural Affairs (DEFRA) specifies the non-statutory requirements for the Site Waste Management Plan (SWMP) and provides the template. The SWMP applies to all aspects of construction work including preparatory work such as demolition and excavation. The plan must be implemented and then updated as construction proceeds, with a greater level of detail for projects that cost more than £500,000. All waste transactions must be recorded or referenced in the plan to prevent the likelihood of fly-tipping. At the end of the project the completed SWMP with records of all waste management actions needs to be reconciled against what was planned before work began. Regular updating during the construction phase should make this a relatively straightforward process. SWMP should be kept in accessible place for a regulatory compliance check. The template of the site waste management plan can be downloaded from Appendix A at http://webarchive.nationalarchives.gov.uk/20130403020108/ http://archive.defra.gov.uk/environment/waste/topics/ construction/pdf/swmp-guidance.pdf Considerate Constructors Scheme published the template for the waste management plans aimed at smaller construction businesses to help them comply with waste management legislation. The template is an Excel spreadsheet with common construction works Waste Codes. It is very straightforward and can be obtained here: https://ccsbestpractice.org.uk/wp-content/ uploads/2015/07/Introductory-WMP-Template1.xls (Source: DEFRA, CCS)
THE SWMP SHOULD CONTAIN THE FOLLOWING
RESPONSIBILITIES • • •
The client The principal contractor The person who drafted the plan
DESCRIPTION OF THE CONSTRUCTION WORKS • •
The location of the construction site The estimated cost of the project
MATERIALS RESOURCE EFFICIENCY •
Any decision taken before the SWMP was drafted to minimise the quantity of waste produced on site.
WASTE MANAGEMENT • •
Describe each waste type expected to be produced during the project For each waste type estimate the quantity of waste that will be produced 9. For each waste type identify the waste management action proposed (including re-use, recycling, other types of recovery and disposal)
WASTE CONTROLS AND HANDLING • •
A declaration that all waste produced on the site is dealt with in accordance with the waste duty of care.4 A declaration that materials will be handled efficiently and waste managed appropriately.

The construction industry produces the enormous amounts of waste due to million tonnes of material used. The building works are connected with the production of over 100 million tonnes of waste, but only 25 million tonnes is disposed of.

BUILDERS EDUCATION
Construction Plant Competence Scheme Construction Plant Competence Scheme (CPCS) is the most popular and best-regarded competence scheme that provides skills cards for the plant sector of the building industry. It was introduced in 2003 and issues cards for over 60 plant and related occupations. The scheme assesses the applicants’ competencies, qualifications and raises standards in the plant sector. It aims to provide the identification for operators, increase health and safety standards through testing, improve employment prospects for operators. CPCS ensures that worker has the accepted standards of skills to work as an operator of the plant within the field of construction. The scheme is directed to plant operators, slinger/signallers, individuals securing plant and equipment to vehicles/trailers for transportation, in-
20
dividuals planning and controlling lifting operations. How to get the operator card? Red Trained Operator Card- it confirms the level of core skills and knowledge, it lasts two years and can be issued for experienced and in training operators who are being measured against national standards through an SVQ and NVQ. To get the card, the applicant has to: • pass CITB health and safety test • pass CPCS technical test • within two years achieve CPCS theory test • pass CPCS practical test Blue Competent Operator Card- it confirms the level of health, safety and environment test through CPCS theory test, operating ability through a CPCS practical test and the competence evidenced by SVQ or NVQ. It lasts five years and is renewable. To get the card, the applicant has to: • prove the achievement of SVQ or NVQ for CPCS • pass CITB health, safety and environment test • achieve CPCS theory test and practical test

100% Smoke Free Policy for Building Sites The recent fire on the construction site in Essex lead to the discussion on smoking on building sites. On the 18th August at approximately 11.20 am the three storey council building in Debden was set on fire. The reason for the blaze is not yet confirmed. In 2007 the smoke-free legislation was launched in the UK to ban smoking in all enclosed workplaces and public spaces. On construction sites, main contractor is responsible to display warning notices. Local authorities are enforcing the legislation and can issue fines for not adhering to it. Health and Safety Executive (HSE) requires from employers to reduce the risk to health and safety including from second-hand smoking. • Employers should have a specific policy on smoking in the workplace. • Smoking policy should give priority to the needs of non-smokers who do not wish to breathe tobacco smoke. • Employers should consult their employees and their representatives on the appropriate smoking policy to suit their particular workplace. The principal contractor should set the rules, but usually smoking is banned on most of building sites due to various flammable materials stored. In such circumstances, there might be the separated area for smoking during the break or workers have to leave the site and smoke outside. Moreover, smoking is prohibited in the cabs of heavy construction equipment, both owned or rented. There should be a designated person who will ensure workers compliance with the site smoke free policy. Contractor have to display a no smoking sign
in the building site and make sure workers do not smoke in enclosed areas. No smoking signs should be placed at every entrance to a public site and the structure under construction. On a private residential project, signs must be posted once the structure under construction becomes enclosed. The building is considered enclosed as long as it has ceiling or roof and walls, whether on a permanent or temporary basis. Businesses can be fined up to £2,500 if they do not stop workers from smoking and up to £1,000 for lack of information on a site. Workers can be fined up to £200. Smoking might be allowed on a private construction sites in the open area or outside the structure on the private area if the owner has not declared it smoke-free. Smoking in the enclosed structure will be prohibited. Banning smoking on the construction sites
is the common industry practice. It often includes also vaping, so called e-cigarette smoking. E-cigarettes are battery operated devices without the smoke but the vapour acts like it. Often contractors are implementing the smoke and vapour free policies on their sites. Careless smoking could cause fire as construction site is packed with paint, chemicals and flammable products. Moreover, smoking might lead to the productivity losses. Workers who smokes before and after work plus during breaks only tend to be more efficient. Productivity losses due to smoking 5-7 cigarettes a day are larger than due to sick leaves. It is worth to educate labourers about the risk of careless smoking on site and financial fines.

Fire Door Safety Week 2018
The campaign programme include, amongst others, the launch of an online Fire Door Inspection tool and numerous Fire Door Awareness Events across the UK. One of the most important messages promoted during the Fire Door Safety Week is the 5 Step Fire Door Check. Follow this guidance and report any findings to the building owner or manager or local authority: 1. Check doors certification- certified fire doors will be labelled or with a plug on the top 2. Check gaps- the gaps around the top and sides of the door should be less than 4mm when closed. If the gaps are too big smoke and fire could travel through the cracks. 3. Check seals- seals are ensuring the fire doors performance. Most fire doors have a smoke seal around the perimeter and the intumescent seal. This brush or fin seal should fill the gap when the door is closed. 4. Check hinges- there should be minimum 3 hinges and all hinges should be firmly fixed with no missing or broken screws.

Check if the doors closes properly- fire door only works when it is closed. Fire doors should close firmly onto the latch without sticking on the floor or the frame. Fire doors should never be propped open. According to the Atomic research 2017, since the Grenfell Tower fire tragedy, over 67% of surveyed apartment renters admitted that their landlords have not been discussing the fire safety measures in their accommodation. Fire protection systems in buildings consists of built in fire protection, sprinklers and fire alarms. Fire doors are one of the most critical elements of passive fire protection. Fire doors keep fire and smoke away for a period of time to allow people to be safely evacuated. Hannah Mansell, spokesperson for FDSW, as well as British Woodworking Federation (BWF) Head of Technical Research and Insight, chair of the Passive Fire Protection Forum and a trustee of the Children’s Burns Trust, says: “Through Fire Door Safety Week, we will once more renew our efforts to ensure that residents, landlords and building owners across the UK are armed with the information they need to make informed decisions that will improve safety. There is no doubt that fire doors, fully fitted with their correct and compatible components, that
are properly installed and maintained play a crucial role in saving lives in the event of a fire. The legacy of neglect means more lives could be lost as a result of substandard fire protection measures. We know that the necessary corrective actions will cost and that is why we are asking the Government set up a Building Safety Fund for Housing Associations and Local Authorities to carry out replacement and repair works. Finance should not be used as an excuse. The stakes are too high.” Mensell added: “Over the last year, there has been significant discussion about the responsibility of landlords, councils and Housing Associations to ensure the safety of their tenants but there is still a massive learning curve in terms of awareness about how fire doors that are correctly specified, installed, maintained and of course closed can limit the effect of fire and smoke, and what to do in the event of a fire. Because of this uncertainty, our focus for fire door safety week this year is “shutting the door on fire and smoke” and we want to educate everyone on how effective fire doors can be in stopping the spread of fire and smoke.” For more information visit www.firedoorsafetyweek.co.uk

Roof Pitched
In this brief guide, we will explain what kind of the physical processes occurs inside the construction of the pitched roof and what is essential to building it sound and stable. With regards to the maintenance and the use of the building, the thermal insulation plays the vital role. It is estimated that in pitched roofs approximately 30% of the heat energy generated by heating systems escapes easily. This significant amount comes from thermal bridging mainly due to the massive beams running through the roof structure via which the heat moves faster. Moreover, the moisture condensation in case of the poor ventilation might lead to the accumulation of moisture inside the roof and thus to the lowering of the thermal efficiency of the building.
Evaluation of the existing roof condition Often roofs’ construction of the existing UK houses are already heavily worn-out with air or wa-
24
ter leaks, smaller or larger damages due to age and exploitation. It is necessary to either completely replace the roof structure or roof covering or refurbish the damaged part. It is recommended to employ the surveyor to assess the condition of the roof. The specialist will check the roof covering, guttering, airtightness, ventilation and insulation efficiency. Moreover, he will be able to assess the condition of the ridge, battens and rafters. Pitched roof components include: • RIDGE - the top of the roof constructed by the inclined surfaces at the top of the slope. • VALLEY - place where two sloping surfaces intersects and the exterior angle is less than 180 • VERGE - the edge of the roof which run between ridges and eaves • COMMON RAFTERS - run from ridge to the eaves at spacing of 30 to 45 cm • TRUSS - it is the frame constructed of the triangles to support the roof top • EAVES BOARD - ends of lower roof covering materials are rest on eaves boards, which is made of wood and placed at the bottom of rafters
•
POST PLATES - are laid parallel to the face of the wall and support rafters • BATTENS - made of wood and nailed to the rafters to give support for the roof covering • PURLINES - wooden or steel parts by truss or wall, used to support rafters • STRUTS - give support to purlins to prevent detection and transmit roof loading to loadbearing structure below. • COLLAR - ties the roof at the purlin level • CEILING BINDERS/HANGERS - support long span ceiling joists We can distinguish between single roofs, double roofs, trussed roofs or trussed rafter roof. The position of the rafters make a huge difference in the roof construction. The standard fink roof truss is common for 35 percent degrees pitch or less, but does not allow for loft accommodation. In the case of attic truss roof the beam and struts make a wide opening easy to convert to living space. Generally the spacing of rafters and ceiling joists should be not more than 600mm. The size and spacing of tile battens should be in accordance with the roof covering manufacturer’s recommen-
(Illustration source: NHBC, Part 7 Roofs, Chapter 7.2, p.9)
CONSTRUCTION TECHNOLOGIES
The optimal thickness of insulation for the attic purposes is approx 25-30 cm of panel stone wool laid in two layers. Reduce the negative impact of thermal bridges by fully covering the roof slope with the insulation layer, limit the size and number of fasteners and other elements passing through the thermal insulation layers, but also to ensure the proper air circulation that will allow any moisture to vapour. The underlay should not be exposed at eaves where the proprietary eaves guards can be used to protect it. We can distinguish between two types of the insulation of the pitched roof- warm deck and cold deck. Warm deck is where the insulation is placed on top of the rafters/joists, and the roof covering, for instance, felt or tiles are then placed over the insulation. The battening and tiling is then fixed down over. The thickness of insulation will vary depending on the manufacturer’s specification. A cold deck is where the insulation is placed between the joists/ rafters or in between the ceiling joists in the case of a pitched roof. Ventilation is required for these roofs. The thickness of insulation in both cases will vary depending on the material you use and the manu-
dations. Battens and counter battens should be as specified in the engineer design. Nails for fixing battens should be 3.35mm (10 gauge) x 65mm long. For trussed rafter roofs not subject to uplift, the minimum fixing should be two 4.5mm x 100mm long galvanized round wire nails, skew nailed, one from each side of the trussed rafter. Alternatively, truss clips can be used. Metal straps might be required in some cases. Lateral restraint straps should have a minimum cross section of 30mm x 5mm and a minimum anchorage downturn of 100mm.
Insulation How to insulate the pitched roof to allow for ventilation and prevent the moisture condensation? It is the complex task as it is necessary to apply insulation that features the low thermal conductivity, allowing to maintain the U values max heat transfer coefficient ≤ 0.18 (W / m2K), but also one that will effectively secure roof truss elements. In this respect rigid insulation with low density and disturbed fibres structure is perfect. Such insulation not only fits easily between the elements of the structure and fills the voids, but additionally increases the level of protection of the wooden truss against fire. Still a lot depends on the thickness of the insulating material.
25
facturer’s specification. The roof should have vents installed along the eaves to both front and rear or from side to side. In the case where the insulation is placed between the rafters then vents should also be placed along the ridge. In case of the roof refurbishments, it is necessary to assess the risk of the damp or mild forming on the surface of building partitions. It can be done by measuring the temperature coefficient fRsi defining the difference between the surface temperature and the outside air temperature, divided by the temperature difference between indoor and outdoor air. The temperature coefficient fRsi should not exceed the value of the critical factor fRsi, max. The air condition in rooms vary but the commonly accepted minimum value of fRsi = 0.72 for rooms with an average monthly air temperature of 20 ° C and an average relative humidity of 50%. In practice, such parameters can only be achieved in air-conditioned rooms. In residential buildings, with gravitational ventilation, the relative humidity of the air can be very different and usually significantly exceeds that 50%. It should not exceed 80%. In the general case of a roof insulated with rigid insulation panels, the amount of condensed dew should not exceed 0.5 kg / m2. Rigid insulation to be effective requires the proper joining and sealing of the gaps.
Ventilation BS 5250 sets out the minimum requirements for roof space ventilation. The design of the roof dictates the choice of the ventilation system or products. The ventilation requirements depend on the type of roof membrane used under the tiles or slates and battens. If the roof membrane (underlay) features a high moisture resistance, then the building regulations require a 50mm wide ventilation gap beneath the roof covering and tiles. In the case of the ventilation of the pitched roof is ensured by leaving the void left between the insulation layers. This allows removing the excess moisture from the structure thanks to the air stream. We can distinguish between primary and secondary roof ventilators called voids. The central roof vent is below the rafter, while the secondary roof vent is higher, usually between the beams and roof plate. The position and type of the ventilation also depend on the degree of the roof slope. In all kinds of roof, ventilators have to run along the eaves and along the opposite sides of the roof to form the cross-flow ventilation. The primary roof ventilators In the standard pitched roof where the slope is of 15 degrees or greater, the airflow void should be
26
Paroc
BUILDERS EDUCATION
of 10mm. In the case when the slope is of less than 15 degrees, the opening of at least 25mm should be left to allow the airflow. In the pitched roof with the accommodation on the attic, the airflow gap of 25mm is required. Such airflow void allows the air to heat up, absorb the moisture, and direct it upwards until it leaves the building through the bridge holes. The secondary roof ventilators In the case of the standard pitched roof, the ventilation has to run between the roof covering and the roof insulation. The ventilation has to be provided in a continuous way on both sides of the roof. The airflow void should be of at least 25mm in the case of both more than 15 degrees slopes or below 15 degrees roof slopes. However, when there is an accommodation in the attic the airflow opening of 50mm is required.
Air tightness In most cases, there is overpressure in the upper parts of the building caused by large temperature differences between the outer and the inner side of the roof, which in part explains higher thermal losses than in case of external walls. In order to avoid condensation of water vapour, and consequently damages caused by moisture, the vapour barrier should be considered on the inside of the roof, and all connections, ducts and elements
connecting the roof trusses with ceilings and walls should be appropriately sealed. The tightness of the building envelope is measured with the standard pressure test. However, it is necessary to note that most of slates and tiles are sufficiently ‘air open’ to allow the adequate air movement through the void between the slate/tiles and the underlay. If the air flow is not known, it is necessary to allow for roof space ventilation or batten space ventilation for instance in the form of 25mm gap at eaves and 5 mm gap at ridge, with 25mm deep counter batten. Some underlays or insulating breather membranes allow to upgrade insulation and manage condensation without raising the roofline. This option is particularly interesting in case of the roof retrofitting projects, as it can be done without any disturbance to the building occupants. The renovation works might reveal that the insulation may be limited based on the rafter depth and it may not be practical to put additional insulation under. Moreover, in case of the plaster ceiling or a lath applying the layer of the insulation into the rafter space may damage the ceiling below. New builds are fitted with the vapour control layer but in the case of the existing buildings the structure has to be checked to assess the need for a ventilated air void. In case where 50% of the roof is being refurbished, the insulation has to be upgraded too.
BUILDERS EDUCATION
The pitch roof has to support loads coming from different sources, including: • materials- tiles, battens, felt, insulation • weather- wind, snow, rain • additional weight- maintenance worker etc. The strong wind need to be offset by the stable roof structure. This is achieved by using approx. 1.2m long straps with a cracked end which is fixed to the wall plate (to which the roof timbers are fixed) and then the inner skin of the wall at every 2.0 centres. Timbers in a pitch roof spread away if ceiling joists won’t stop them. Ceiling joists should be fixed to the bottom end of the rafters. In case of opening in the roof the other system should be used to tie rafters to wall and stop from spreading. Holding down straps might be required in some cases and the roof covering manufacturer provide guidance on their installation.
Fire resistance Roofs should adequately resist fire spread, so all components should be fire resistant or special treated including roof coverings, chimneys and flue pipes. Roof timber and felt should be kept away from heat sources. Junctions between roofs and walls shall resist fire spread.
Fascias and soffits Timber used to construct fascias, bargeboards, soffits should be pre-treated with preservative

Loads
against decay. All joints should be cut and fixed. Fascias should have two fixings into each rafter and should be fitted to accommodate the correct pitch.
Roof drainage Roof drainage with rainwater gutters and downpipes of sufficient size should adequately carry rainwater away from the roof. Dormer and porch roofs might be fitted with a drainage system as well. Flashings and soakers should be of the same materials. The pitched roof, from the structural and thermal point of view, is a highly sensitive place, which directly affects the energy standard of the finished
building. It is worth to take into consideration the proper functioning of the ventilation voids at the design stage, by choosing the right type of insulation and ensuring adequate airflow inside the structure.

Autumn is already around the corner, but the modern conservatory will allow you to enjoy the garden for longer. Greenhouse helps to open up space, bring in more light but also make the garden the permanent element of the interior. This additional space for dining or relaxing with family in the sunshine, surrounded by garden will add value to your home. 30
Conservatory allows to enlarge the lounge or living room and make all year enclosed glass space that can be used as the accommodation. When designing the conservatory, we should define its purpose of determining the technology and final project. The location is also important, but in the UK often it is dictated by the properties features. The amount of sunlight entering the interior will give the optimal conditions for relaxation with a temperature of just over 20C. On the other hand, locating conservatory from the south side should result in more sunlight and higher temperatures what will create perfect microclimate for exotic flowers and plants. However, in such a scenario, some shading
elements are recommended. The least favourable location for the conservatory is from the norththere will be little sunlight here so that the room will be shady and slightly cool throughout the year. However, locating from the north is recommended to artists - painters or photographers - due to the even and almost unchanging distribution of light in the interior, allowing work throughout the day. The construction of the conservatory should be stable and durable - profiles forming its skeleton can not deform under the influence of strong wind or snow. The systems available on the market differ not only in the construction details but, above all, in the material used for their production - wood,

Nowadays, on the market, there are available lightweight, durable and corrosion-resistant aluminium profiles which are narrow and result in a larger glazing surface. The eaves structure can be reinforced with aluminium or steel profiles, which allow for sliding or folding doors to be mounted in the walls. Depending on customer preferences, there are rafters or external masking strips in the soft (flat) version or with a clearly outlined, rectangular shape. Profiles can be finished in any colour: RAL palette, structural or wood-like tones, anode or bicolour, which means a different shade of the profile on the
outside and inside. In this way, we can quickly adjust the shape and structure of the conservatory to suit the design and style of the existing building. The slope of the roof at which the sun’s rays will fall at the right angle should be between 5% or 45%. It will result in the best exposure to sunlightthe sun rays will penetrate through it effectively heating the interior. It is recommended to consider solar roofing that reduces UV rays. The conservatory is made of the safety glass that after breakage will not spill. In case of the south position, it is recommended to select glass covered with a reflective coating that reflects the sun’s rays. Conservatory improves the thermal balance of the

The conservatory is also an excellent thermal buffer for the building during the cold autumn-winter period. In both cases, however, it must be perfectly designed and carefully made.
Building Regulations and Planning Permission Adding conservatory to the existing house is permitted development. Planning permission is not required to build the conservatory unless it is the listed building, or it is on green belt land. The permitted development rights allow to make improvements and alternations to the building like a conservatory within the specific criteria: • A conservatory cannot exceed the area of half of the land around the building.

A conservatory must not exceed from the rear wall of the existing house further than 3 meters in an attached house or 4 meters in a detached house A conservatory must not exceed 4 metres in height (or 3 metres if it is placed within 2 meters of the building) Maximum eaves height should be no higher than the eaves of the existing house. The highest part of the conservatory should be no higher than the roof ridge line of the existing home. A Conservatory must not be at the front of the building and facing a road. A Side conservatory must not have a width greater than half the width of the original house. If the building was extended, the planning
permission might be required to extend it with the conservatory further Refer to the Governments Planning Portal for full criteria concerning building conservatory. Always check with your Local Planning Authority whether permitted development rights apply. Building Regs for conservatories are same as for other build structure unless: • the total area of conservatory does not exceed 30m2 • 50% or more of walls are of glass • 75% or more of the roof is transparent glass • all glazing is of toughened safety glass • it is single storey on the ground level • conservatory is separated from the existing building by quality doors, walls, windows • there must not be any drainage installed • there is independent heating system- radiators must have their own switch on/off controls • glazing and electrical installation comply with building regs Any new structural opening between the conservatory and the existing house will require building regulations approval, even if the conservatory itself is an exempt structure. If the planned conservatory does not comply with the above criteria there is need to contact local planning authority for advice and approval.

The Guide to Plumbing Plumbing refers to either drainage or sanitary pipework, which are built in accordance with the architect drawings. Design plans should include a location of sanitary fittings, drainage runs, hot and cold water pipes, a gas supply pipe, water storage cylinder, electrical units, harvesting system, UFH, etc. Please note that the following guidance is the introduction into the subject. Refer to Building Regulations, Approved Document H, which covers drainage and waste disposal and British Standard BS EN 12056:2. 34
Sanitary system consists of horizontal branches, vertical stacks, drains, sewer. It should be done in such a way to allow for the unobstructed flow of waste from an appliance to the underground drainage. To do this, it is necessary to choose the proper size and type of pipes and gutters. In order to do so, we have to know the expected rate of discharge and the slope (minimum gradient 18) of the pipes. By determining the occupant’s load base on the proposed area, we can establish the required number of plumbing fixtures. On the market, there is a wide range of residential plumbing pipes like for instance: • Copper pipes which are durable and not prone to leaks. These pipes are heat resistant, do not pollute drinking water and can be recycled. Usually comes in various sizes depending on the type of use • Galvanised steel is not used in residential projects anymore, but was widely used before and houses built 1930-1980s

might have this type of pipes. Galvanised pipes are heavy and coated with zinc what might cause rusting. Might cause discolouration of water and reduced water pressure. Corrosion of pipes might occur over the time. PVC pipes are light and easy to work with. Do not rust or corrode, are durable. Perfect for high water pressure. Used in sink, toilet, bath, vent stacks etc. Can carry only cold water. CPVC pipes contains chlorine but are more flexible then PVC pipes and can be used for both hot and cold water supply. CPVC should be insulated to avoid freezing PEX pipes are very heat resistant so can be used for both cold and hot water. PEX pipes can be used in various connections Stainless steel pipes are strong and corrosion-resistant but more expensive than copper piping.
CONSTRUCTION TECHNOLOGIES
Other popular materials for pipes are polyethylene PE HPDE, ABS, PP acoustic soil etc. Each type of the fitting is jointed in a different way. For instance, pipes can have a ring seal for push-fit joints or can be solvent-weld jointed. Water test or smoke test can be done to check the air tightness. All points of discharge should be fitted with a water seal trap. Trap prevents foul air from the system to enter the building. There are minimum trap sizes and seal depths for the various appliances. Traps should be fitted directly after appliance, below the outlet and should be fully accessible and removable. Traps are available in various options like low-level bath, shower trap, anti-siphon bottle trap, S o P tubular traps. Branch discharge pipes discharge to stack or other branch pipe. Often appliance can discharge to a gully. If the appliance is on the ground level, pipe might discharge directly to a drain or a gully. The crossflow into other branch pipe and any bends should be avoided. Pipes serving a single appliance should have at least the same diameter as the appliance trap. Junctions on branch pipes should be done with a proper sweep. It is necessary to avoid cross-flow which occurs when two branches are installed opposite each other. The no connection zone and a parallel junction underneath is required. There are also branch ventilating pipes formed by combining two or more vent pipes. If a branch pipe exceeds these limits, it should be connected via a branch ventilated pipe to external air or a ven-

eter or bigger than the appliance trap. Branch is any piping fixture other than main, riser or stack. Discharge stacks are the vertical connecting pipes that leads to the central stack. All stack discharge
to a drain. Stacks should have the adequate diameter to allow for the positive pressure. The internal diameter of the stack should be not less than that of the largest trap or branch discharge pipe. To prevent water seals in the traps from being lost by pressures which can develop in the system, discharge stacks should be ventilated. In the connection of the ground floor appliances stub stacks can be used. The vertical drop to the drain must not exceed 1.5m from a WC and 2.5m from a waste appliance. Drains receive the discharge from soil, waste and sanitary system and it conveys it to the sewer. Vent stack is a vertical piping to which connections are made from the discharge side of traps and through which gases, odour is removed. Branch vent is connecting one or more individual vents with a vent stack. Pipes sizes should not exceed the dimensions for diameter against pipe length. At the head of

•
Single stack system: air admittance valves underground drains, ventilation is to be provided, either by a soil pipe or a separate ventilation pipe. Air admittance valves provide ventilation of the drainage system to prevent the loss of water seals in traps. Valves should be positioned in such a way to comply with Building Regs and to avoid freezing. The drainage system should also be ventilated adequately. If the connecting drain is fitted with intercepting traps, air admittance valves should not be used. There should be access to allow for repairs. This can be done by providing rodding points in discharge stacks. Rodding points in stacks should be above the spillover level of appliances. Over tightening connections of tubes, pipes and fixtures might lead to cracks and water leaks. Never apply too much force on a pipe as the excessive pressure might destroy the fitting and cause leakage. Same applies to over tightening of the plastic fittings on toilet or faucet supply tubes. • Wrapping around threads should be done three times and clockwise, what ensures that the tape will not unwind and properly tighten the fitting. • Cross-flow should be prevented. The
branch pipe should not lead to the stack in a way that will cause a cross-flow into any other pipe.
Positive pressure has to be eliminated by the correct slopes, pipes size. If the system will have a positive pressure water will leak into the building. Drain-wastevent systems with adequately sloped pipes will ensure the neutral air pressure. If slope can not be achieved, a pump might be required. • Shut off the main water pipe before commencing any plumbing works to avoid flooding. In the next step , attach the new valve or faucet. The stop valve is where the water supply can be shut. Usually, there is an external and internal stop. • Have knowledge of various types fittings and their application. Never mix up parts like wyes, tees, elbows. Avoid misconnections. • Ensure copper pipes are dry before sweating to avoid leaking from the joint. • Insulate pipes in the outside areas to avoid freezing, which will lead to splits and leaks. Plumbing does not seem to be difficult, but getting it done requires the adequate knowledge on fixtures and basic rules. Always use qualified plumber or heating engineer. The Chartered Institute of Plumbing and Heating Engineering (CIPHE) set standards for plumbing and heating engineering industry and has a list of professional plumbing and heating engineers here www.ciphe.org.uk/ find-a-plumber.
