Amey has finalised the design solution to fix a crack on one of the Forth Bridge’s truss end links.
It involves a plate welded repair to the damaged truss end link and jacking the link into position. An access platform is currently being constructed and teams of welders are expected to work day and night, depending on weather conditions. In addition to Amey, two different engineering firms have checked and signed off the plans.
Preventative work will also be carried out on another seven similar parts of the bridge, with structural monitoring systems installed.
The decision to close the bridge last week followed the discovery of defective steelwork, and was made after a meeting of the Scottish Government Resilience Committee.
Amey’s account director responsible for the bridge, chartered engineer Mark Arndt said: “Our teams have been working 24/7 since the defect was identified a little over a week ago. Our design teams have finalised the detailed solution plan, the access platform is under construction and we’ve mobilised all the resources we need to begin the repair works.
“Progress of the repair work is vulnerable to weather conditions. Wind speeds at times make it unsafe for our people to continue but by having our personnel on standby at the bridge and by monitoring live wind-speed data in our control room we’re able to get straight back out to work on the repairs in every available window and our programme remains on schedule for completion in the New Year.”
