The A74 collapsed on London Road in Glasgow in April 2016 between Celtic Park FC and the Sir Chris Hoy Velodrome causing a void approximately 3.5m deep by 12m long and 3m wide.
Working alongside Scottish Water and Donaldson Associates, Morrison Construction devised a scheme to strengthen the weakened ground, replace the existing sewer and water main and resurface the road.
The full scope of works included: over pumping, ground investigation; installation of a cofferdam, new concrete pipes, water main two new man holes, and full road reinstatement.
Due to an abandoned railway tunnel a vibration monitoring system was used while installing the cofferdam.
A full road closure was required due to the traffic sensitive nature and the high profile location.
As the site was beside Celtic Park FC, home games lead to the site being closed or reduced activity, resulting in losing six days of programmed works. Despite this the project was delivered on time and budget.
