Solution Design Work Now Complete

In the week since the Forth Road Bridge closed, Amey’s team of engineers have been working around the clock to develop a solution to a crack in one of the bridge’s truss end links.

The detailed plans to fix the problem have now been finalised, checked and verified by two independent specialist engineering firms.

The repair solution involves a plate welded repair to the damaged truss end link and jacking the link into position.

An access platform to allow repair works to get underway is being constructed. The platform will permit teams of welders to work day and night, when weather conditions permit.

Chartered Engineer Mark Arndt, Amey's Account Director responsible for the bridge 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.”

In addition to repairing the defect, Amey is taking preventative action on another seven similar locations on the bridge to prevent any issues from occurring and structural monitoring systems are also being installed at these locations.

Transport Minister, Derek Mackay said:

“Our priority is to get the Forth Road Bridge operating as soon as possible and our engineers are doing all they can to make that possible.

“They are working tirelessly on designs for the repair and are putting the equipment they need in place so that it can be completed in good time.

“It is difficult and technical work and the team is to be commended on its commitment to getting the job completed despite the weather conditions.”
