Notice Abstract

Amey are seeking a suitably experienced contractor to undertake the replacement of the main gantry runway beams on the suspended span of the Forth Road Bridge (FRB). The beams have come to the end of their service life and are to be replaced with an asymmetric beam section. The current runway beams run the full length of the suspended span of the FRB (1823m) on the east and the west sides, allowing the existing underdeck gantries to move along the length of the bridge. The beams are fixed to a supporting structure which is connected to the bottom chord of the main stiffening truss. Amey are currently undertaking a trial replacement of the beams on the North Side Span between panel points 0-5 (approx length of 45m. The trial will pilot proposed installation methods and testing processes. The new runway beams will be supplied free issue to the successful contractor after contract award. The works associated with this project will comprise, but shall not be limited to the following activities; - Fabrication and commissioning of temporary gantries used to facilitate removal of the existing runway beam section and installation of new section. - Fabrication of testing rig to allow for on-site load testing of new sections - Collection of new beam sections from KA 11 and transportation to the contractor’s fabrication facility. - Cutting of sections to size after site survey, execute holing and any other necessary fabrication works. - Blast and galvanise all new runway beam sections - Undertake the removal of all current runway beams on the North Side Span (408m span length, 816m of runway beam) and the Main Span (1006m span length, 2012m of runway beam) of the Forth Road Bridge suspended structure. At this point, the South Side Span runway beams will be replaced by others. The scope of these works may increase to include the works at the South Side Span. - Replace all fixings on runway beam support structure - Undertake the installation of new runway beam sections on the North Side Span and Main Span - Load test new sections on site, record deflections and report to the Engineer. - Fully commission system and hand back to Amey. Any contractor wishing to bid for the works must have the relevant National Highway Sector Scheme (NHSS) approvals and must be certified to undertake steelwork execution to EXC3 quality requirements. The contractor must have experience of undertaking works on long span bridges and completing projects that involved managing risks such as working at height, working above water and lifting activities.
