Crossgate Bridge, South Shields Client: South Tyneside Council
A69 Carlisle - Newcastle Trunk Road, Hexham Client: Roadlink (A69) Ltd
Concrete repairs were completed to the existing bridge abutments and piers as well as carrying out the replacement of the existing waterproofing on the bridge deck. The crash barriers were also removed and replaced and new kerbing laid on the road deck. The works were completed to improve and extend the lifespan of the existing structure to mitigate the cost of future maintenance works. The works were completed in two halves to allow the bridge to remain operational throughout the duration of the works as it was a primary access point to the town centre.
The new single span bridge was constructed to replace the four span pedestrian bridge which collapsed in 2009 due to heavy floods. The new bridge is a single span tubular steel Warren truss structure, with a span of 52m and a width of 2m. The substructures comprise concrete abutments formed from circular 3.6m internal diameter pre-cast concrete caisson units in-filled with lightweight concrete. The upper half of the caisson was reinforced with a steel cage. Due to the close proximity to the River Derwent the caissons were installed and the concrete plug cast under water. The abutments support a concrete wing wall which form a ramp for the walkway.

Skipton on Swale Bridge, North Yorkshire Client: North Yorkshire County Council
The scheme comprised the completion of structural repairs to three existing steel and masonry Metro Bridges together with shot blasting and repainting. We completed the works in three separate phases and comprised local strengthening of the trough girder bottom flange to increase the capacity of the structure. Collision protection measures were installed to protect the elevations. Necessary shot blasting works were undertaken to strip, clean and repaint the existing structure. Upon the finalisation of the works necessary crack repairs were undertaken to the damaged areas of the structures.
Skipton on Swale Bridge is a Grade II listed 8 span, masonry arch structure constructed of coursed and dressed sandstone ashlar blocks constructed in 1781. The overall length of the structure is approximately 110m. The works comprised the removal of coping stones and parapets over the river spans and rebuilding where possible using the existing. The existing river cutwaters were dismantled to river level and rebuilt using new stone. Spandrel walls were partially taken down and rebuilt and other areas let in with new facings. Repointing of the abutments, spandrel walls and wing walls completed the scheme.

Hungate Footbridge, York Client: Hungate (York) Regeneration Ltd
We were responsible for the completion of a major earthworks operation to re-profile the site. The large amounts of ash previously deposited on site was used to reshape the railway embankments. Demolition of an existing steel plate girder bridge deck was required along with the demolition of existing abutments. We were responsible for the design and construction of the 60m span tied arch bridge for the C2C network. A major grouting exercise was carried out to minimise the risk of settlement to the new bridge.
A new pedestrian/cycle bridge was installed. Piling was carried out on either side of the river as part of the foundation work, along with the construction of in-situ concrete bank ‘seats’ for the mast and cable stays. The construction of the bridge was completed off site at SH Structures of Sherburn in Elmet. The steel-framed bridge structure measures 26m in length and 5m wide. At 29 tonnes, it was decided night time transportation was the best option and would avoid unnecessary traffic congestion. Once on site, the bridge was fitted with stainless steel balustrade railings and timber decking.

A195 Lambton Interchange, Sunderland Client: Sunderland City Council The A195 Lambton Interchange required maintenance works to strengthen the bridge. The works involved the removal of the existing surfacing, concrete repairs to the deck structure, joint repairs and new sealant installation and the placement of new surfacing to the footbridge. The road bridge required new concrete parapets to replace the existing eroding ones. As the structure was
temporarily weakened by the eroding parapets, a special technique for the removal of these parapets was required in order to reduce the strain put on the bridge. In place of the traditional drilling device, we used hydro-demolition to break down the parapets using high pressure water jets.

Polam Lane, Victoria Embankment Client: Darlington Borough Council The existing Victorian Bridge on Polam Lane was restored and repaired. Works involved the fabrication of a new frame adding the old components. The 20m bridge is a listed structure meaning the original scrolling handrail features were to be maintained. We removed the bridge and transported it to an off site location and dismantled.
We removed the handrails and the old deck was disposed off. We supplied a new steel deck with timber planks with a non-slip coating applied to the timber. The cast iron scrolling handrails were removed and refurbished by sandblasting all layers of old paint to restore old features and repainted according to the original Victorian colour scheme.

Butterfly Bridge, Gateshead Client: Gateshead Council Works involved the replacement of a footbridge over the River Derwent to replace the previous bridge which had been washed away during floods. The new footbridge features a number of additional improvements, such as better access paths and a wider bridge deck. The new bridge is single span which negates the need for a supporting pier which had been a contributing factor
to the original bridges demise. The bridge was built off site and transported in three pieces to site where they were fixed together and lifted into place by a 500 tonne crane. To accommodate the crane, access improvements and a working platform were completed prior to the arrival date.

Ramp to Multi Storey Car Park, Rotherham
ÂŁ963,000 Client: South Yorkshire Passenger Transport Executive (SYPTE)
The car park, ramp and bridge were built in the late 1960s and are situated above the main bus station next to the River Don. The bus station currently has19 stands and is a major transport hub for the local community and the surrounding areas. The aim of the scheme was to carry out refurbishment and major repairs to the elevated access ramps, internal car park together with the replacement of the access bridge structure. Bridge - The project was awarded on a ‘Design and Build’ basis and the brief was to provide access that met current design standards with an extended lifespan of 60 years. Through initial assessments, we elected to rebuild rather than repair the access bridge. During this process, it was essential to consider future maintenance and minimise the requirements to close the bridge in the future for the client. The works involved the demolition of the existing bridge and the fabrication and fitting of a new bridge with limited access from one side of the river whilst maintaining the travel operations in the SYPTE Bus Interchange below. Ramp Bridges / Abutments - The supporting pier foundations were assessed as being suitable to meet current requirements and were retained but required concrete repairs and strengthening works to bring them up to standard. New parapets were also provided
to bring them upto the required safety standards. Protection - To ensure the new bridge achieved a 60 year life span and in order to reduce the risk of corrosion to the existing reinforced concrete pier strengthening, a Cathodic protection system was installed. Due to the steep access profile, the client had previously instigated a salting regime that had contributed to accelerated corrosion. We installed a trace heating system underneath the new road surface and within the concrete deck structure to prevent frost build up and remove the need for salting and the resulting corrosion and wear. Car Park - Additional works for the car park were awarded and involved concrete repairs and waterproofing. Damaged concrete was broken out, refilled and waterproofed. These activities were critical to the re-opening of the car park and so prior to removal of the existing bridge, sufficient quantities of materials were delivered so that repairs to the car park and the bridge could be completed simultaneously to minimise delay to the car park opening. Health and Safety and Risk Mitigation - This was of critical importance given the location of the works high above the River Don. We designed an independent scaffold crash deck which spanned the entire width of the river. This scaffold provided safe access and prevented debris falling into the river. Prior to erecting the scaffold, analysis of bus movement

Contract Duration: 20 weeks Form of Contract: JCT Design and Build Contract 2011
paths was carried out within the bus interchange and a safe working zone was installed using fencing and water filled barriers which directed the buses safely past the scaffold and created designated transport and pedestrian routes. Public/Stakeholder Liaison - Regular meetings were held with the bus companies to address any concerns they had about the project and the closure of the interchange lanes. The client was heavily involved throughout the project with weekly meetings held to discuss progress and address any questions that arose. Challenges Overcome - Although the bridge itself was in very poor condition, the bridge deck removal proved one of the major issues to manage. The assessment of load capacity indicated that large machinery could not be supported during demolition and so the removal of the bridge was carried out by diamond-cutting through the reinforced concrete overlay, breaking free the shear stud locations so that the deck could be lifted out in panels rather than the usual technique of in site demolition. Supply Chain - We have developed a diverse network of specialist supply chain partners over a trading period in excess of 40 years. These contacts enable us to resource the works with contractors who have been successful with us on previous projects. Our designers URS have assisted us with several Design and Construct
bridge contracts which allowed us to continue existing successful relationships. Added Value - The existing concrete piers which supported the ramp and the bridge were initially earmarked as being demolished and rebuilt. This would have been costly in both time and the closure of the car park to local residents. We worked with our designers to offer a system which involved concrete repairs, an additional reinforced concrete skin and Cathodic Protection which shortened the construction period considerably.
Kip Hill Bridge, Stanley
ÂŁ1,760,000 Client: Dunelm Homes/Bowey Homes
Appointed as Principal Contractor, we undertook this Design and Build project, which was part of a development to turn derelict land into a private housing site comprising 164 new homes. The project required a high level of collaboration between Bowey Homes (Client), the Highways Authority and our Designer, Durham County Council. Early consultations with the Client and Designer produced a design that incorporated value engineering from the outset. The project comprised the removal of the existing steel plate girder bridge deck, demolition of existing abutments, earthworks, grouting and piling for new abutments, road and footpath re-alignment, construction of a new junction and alterations to existing highways and footpaths. The bridge construction was a tied arch of 60m span over an existing heavily trafficked highway. Roadworks / Enabling Works - We completed improvement to the road, carried out realignment works and created a traffic signal controlled junction to form the new road access onto the development. This was carried out in conjunction with Durham Count Council and formed part of a Section 278 Agreement. We also diverted the main service to accommodate the new road alignment and the provision of new services connections onto the site.
Bridge Works - Demolition of an existing steel plate girder bridge deck was required along with the demolition of existing abutments and reshaping of the existing embankments. We were responsible for the design and construction of the 60m span tied arch bridge for the C2C network. A major grouting exercise was carried out to minimise the risk of settlement to the new bridge. On Site Works - We were responsible for the completion of a major earthworks operation to re-profile the site. A major grouting exercise was also completed to minimise the risk of settlement to the new housing from the former mine workings. We also had to deal with the large amounts of ash which were the result of reshaping of the railway embankments and also waste materials which has been previously deposited on the former industrial site. Where possible these were used for re-profiling the site and the remainder was removed and disposed of at a specialist facility. On-site and off-site drainage connections for surface water and foul water were constructed and the existing drainage diverted where it crossed the site. All new roads infrastructure was completed ahead of the building works commencing. Street Lighting and Street Furniture - Installation of 40 standard columns along with signage for the new road layout.

Public Realm - The landscaping scheme was designed and installed including tree installations, shrub planting and grassed areas. Where possible native species have been used to provide habitat for wildlife. Value Engineering - Early consultations with the client and the designer produced a design that incorporated value engineering from the outset. Risk Mitigation - We created dedicated pedestrian routes and diverted the cycle route to ensure minimal impact was experienced during our works.
Skipton on Swale Bridge, North Yorkshire

£937,000 Client: North Yorkshire County Council
Skipton-on-Swale Bridge is a Grade II listed 8-span, masonry arch structure constructed of coursed and dressed sandstone ashlar blocks constructed in 1781. The overall length of the structure is approximately 110m. There are three arches across the main river channel and five flood relief arches.
• Removal of mud banks from the western abutment and downstream side of the eastern river • Reduction of ground levels to the downstream sides of the flood arches to allow flood waters to scape.
The works for this project comprised:
Health and Safety and Risk Mitigation
• Removal of coping stones throughout the length of both parapets to the river spans and set aside for reuse. • Removal of both parapets over the river spans, down to and including the string courses and set aside for partial re use. • Installation of contractor designed temporary works to retain structural core fill comprising Cintec ground anchors and geotextile mattress to retain fill and reduce pressures on reinstated stonework. • Existing river cutwaters dismantled to river level and rebuilt using new stone. • Spandrel walls partially taken down and rebuilt and other areas let in with new facings. • Rebuild parapets reusing existing stones (where possble) • Reposition existing coping stones using new stone where necessary. • Re-pointing of abutments, spandrel walls and wing walls.
One of the main challenges of this scheme was timescale. The allowed closure was only 8 weeks to carry out the whole of the masonry works, including installing the temporary works to provide access and subsequent removal. Although the road was closed to vehicles, the route had to be maintained to pedestrian traffic throughout the works. Due to the extremely tight timescales, temporary works were developed and designed such that they could be installed as the parapets were being removed, maintaining leading edge protection. The system adopted used steel beams spanning over the deck and cantilevering out approximately 1.5m beyond the bridge. From this the support scaffold was slung. Kentledge was provided by steel road plates over the beams which additionally, provided a running surface for plant access and the required footway. During the day, works were halted and pedestrians

carriageway which was originally identified as coming out, offering a substantial saving to the client.
Sustainability
Public and Stakeholder Liaison
Wherever possible, existing stone was identified for re use, even if it needed cutting to a smaller size to be used at a different location.
Early meetings were held with representatives from the client, local traffic department and locals via letter drops and one to one meetings.
Agreements were made with local residents in order to set up a school run, where the children were escorted over the bridge in the morning and afternoon to meet their buses to get to/from school.
Challenges Overcome

The use of the temporary works system, sling the scaffold, rather than building a ‘birdcage’ up and over the side of the bridge saved about 3 weeks on the installation and removal. Because the scaffold allowed machines to run across the deck, savings were made in transportation time and costs, getting the stone from the compound to the work areas and stone could be placed faster and more safely than traditional methods of gin wheels and trolley beams. Because the beams spanned over the deck with an even loading, in conjunction with the Cintec anchors to retain the structural core fill, we were able to leave in the majority of the footway width and all of the
Timescales were extremely tight but through planning and implementation of well planned temporary works these were overcome. The weather encountered was harsh but additional protection measures, together with a site based stone masons workshop, assisted in delivery of a huge amount of stone within the very short timeframe.
