Erskine Bridge Cable Inspections 2024

Tender description

The scope of the works is outlined in detail within the brief. To summarise: the Contractor will facilitate the intrusive inspection of the Erskine Bridge cable stays. Each fore and back stay of the two cable stays will be intrusively inspected at eight distinct locations, amounting to a total of 32 locations. The Contractor is responsible for positioning the provided Cable Access Cradle (CAC) in position on the cable stays and driving the cradle carrying inspectors from Amey & COWI to the designated inspection sites. Inspections will involve removing the cable bands, manually driving a wedge between the strands of the cable bundle, and inspecting visually with the aid of a endoscope. The wedge will then be removed, cable band reinstalled, and cables applied with Metalcoat® (to be provided by Amey) where the coating has eroded or has been affected by the inspection work, including beneath the cable bands. The Contractor will then move the access cradle to the next location until the inspections are complete, removing the CAC to store upon completion. We estimate a start date of 1st June 2024 and an 8 week programme Please contact robbie.gallagher1@amey.co.uk with technical queries and to be sent the full Technical pack as they are over the 100mb limit the portal will allow.
