One week on from the Forth Road Bridge closure, you’ve probably seen photos of engineers inspecting the damage. What exactly is going on?
A team of engineers from Amey have been working around the clock to come up with a plan to fix the crack on one of the bridge’s truss end links.
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.
Chartered engineer Mark Arndt said the platform will allow welders to work day and night, when weather conditions permit.
“Progress of the repair work is vulnerable to weather conditions,” he said. “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.”
He said the repair programme is 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 occuring and structural monitoring systems are also being installed at these locations.
