Specification, planning & construction of quay wall stabilisation works at Kingston Bridge, Glasgow

Kingston Bridge carries the M8 motorway in ten lanes over the River Clyde in Glasgow, and is the busiest motorway bridge in the United Kingdom. Investigation on the behaviour of the bridge revealed the need to stabilise the ground in the area beneath the northwest pier foundation and behind the adjacent quay wall, and to provide additional lateral support to the remaining quay walls in front of the north and south piers. The background to the project, the design approach and choice of construction techniques for the stabilisation works are described in the companion paper, Carruthers et al. (ref 1). This paper describes the main problems considered and taken into account in the specification and planning of the works, and how these and other problems were overcome during construction.
