AFC Wimbledon return to Plough Lane

AFC Wimbledon return to Plough Lane

After a three decade hiatus, AFC Wimbledon return to a brand new 9,000 capacity stadium in Plough Lane, the team’s home since 1912. In addition to the stadium, the development comprises over 600 residential units, retail outlets and community facilities.

GBCP provided support to the developer, Galliard Homes, throughout the project, producing a detailed desk study before two phases of ground investigation, followed by the design and verification of remedial works. The presence of geological faulting was identified during the initial phase of ground investigation, resulting in a variation to the top of the Lambeth Group of up to 29m. GBCP specified a second phase of targeted sonic boreholes, providing fast and detailed information on ground conditions, and identifying a fault zone that covered nearly two-thirds of the site area. GBCP were able to work closely with the project structural engineer to optimise pile depths, diameters and layout to retain all piles within the London Clay, avoiding piling into the Lambeth Group, which contained hard limestone bands and water-bearing sand lenses.

A requirement of the Local Authority, GBCP also undertook ground movement analysis to confirm the proposed basement retaining structures would not adversely impact adjacent highways assets. Using specialist modelling software, potential short- and long-term horizontal and vertical movements were calculated, and a monitoring plan provided to the client.

During construction, several historical underground fuel storage tanks were discovered, and GBCP were able to quickly inspect the area, recover soil samples for laboratory testing, and provide a methodology and verification plan for removal.

GBCP are delighted to have assisted with the return of an iconic club to their historical home, as well as the provision of hundreds of homes and facilities for the local community.
