ISS were instructed on this project to supply the access scaffold to the seven-span bridge carrying the motorway between Swindon and Gloucester.

The works comprised of ISS erecting a slung scaffold to the bridge underdeck for grit blast and painting works. This posed several problems to overcome, not least because the bridge is completely inaccessible, being in the river flood plain.

ISS had the solution though, with our own unique runway system, which allowed us to transfer our scaffold material safely from the compound to the bridge, some 250m away.

The runway was then left in place for the client to utilise for their own works.

“ISS have been the most professional scaffolding contractor I have utilised in the past few years”

ISS were the preferred scaffolding contractor to build a new education campus in Hexham.

Comprising an extensive new-build project and the retention of the Grade II listed Hydro building, the scheme involved designing many complex scaffolds including supporting the existing building.

The Grade II listed Hydro building was to be retained and the new buildings developed to its rear – with the middle school to the south and high school to the north, adjoining the existing Hydro building.

ISS worked hand-in hand with our client, often working outside normal working hours, and designed many complex scaffolds, including support scaffolds and truss-outs that enabled works to progress below, therefore cutting any lost time or programme overrun.

“ISS have provided a range of services at Hexham Schools, but for me what makes them stand out is their technical knowledge temporary works design which is amongst the best I’ve seen. and professionalism”

ISS were instructed to design and build a temporary works structure to support British Telecom cables once the existing Bailey bridge carrying them was dismantled.

The project needed close collaboration with the client to ensure sequence of works are carried out on time, to programme to minimise any disruption.

The first stage was to erect the support towers either side of the carriageway. The tower bases were encased in concrete and back-filled.

The bridging beam section was then made up on ground and craned into position. The cable conduit and cables were then moved from the existing bridge to the new support bridge.

Both towers were then back-filled up to the bottom chord of the bridging beam, then cables were removed and re-positioned to new ground height. 

The bridging beam section was then dismantled and all surplus scaffold above new ground level was cut away.

“Working on our most recent projects, ISS have delivered a competitive, professional service across all aspects within the project. Incorporating a full design and build process from basic to complex scaffolding”

ISS designed and built a bespoke slung access scaffold and containment to the underside of the three-span railway underbridge spanning the river Derwent in Derbyshire, next to Derby County football ground.

Access was needed to the bridge parapets and full encapsulation for steelwork repairs and grit blast to restore the bridge to its former glory.

“It has been a pleasure to have ISS on site and I look forward to working with them on future projects”
