Temporary bridge suitable for public use was positioned within just 15 minutes of track possession
HAKI Bridge System and Public Access Stairs erected in a short total of 15 hours, despite scaffolders never building the system before
The HAKI Public Access Stair allowed for a comfortable walk up the bridge, whilst the sturdy handrails provided strong support and the 2m wide bridge delivered ample room for the busy walkway Along the bridge there were 1.5m high sections to allow for the cladding, keeping the public safe and sheltered from bad weather
Due to significant upgrades and the modernization of South West and South Wales railways, a temporary bridge was required at Gypsy Lane Swindon.
Scaffolding contractor J.F.E. Attridge was contracted to provide a temporary solution, which needed to be a fast and efficient to avoid causing disruption to the busy stretch of track.
The temporary bridge had to span 23.5m across the track and provide a safe, comfortable non-slip walkway during the winter months.
It required a minimum loading of 5kN/m² and internal cladding across the bridge to protect the public from high winds. Two 4.7m tall stairs, suitable for long term public use, were to be provided each side of the track.
The HAKI Bridge System was built off site and out of possession time. The simple systemised components allowed Attridge’s scaffolders to build the 23.5m bridge in 7 hours despite having never built a HAKI Bridge previously. The HAKI Public Access Stairs were also erected by 4 men in a total of 8 hours.
As the HAKI erection method is to build ahead and always behind a guard frame, building the stair in a potentially dangerous area was much safer and easier minimising risk to the scaffolders on site.
Once the stairs were built, the final step was to connect them with the bridge. During one-night, the bridge was swiftly craned and positioned into place within 15 minutes.
Assisted onsite by a HAKI technician, the scaffolders found the HAKI systems quick and intuitive to build.
