The Bargate Centre, Southampton: the engineering geological and geohydrological aspects of the excavation for basement construction
The Bargate Centre is a large, four-storey shopping arcade constructed during 1986–1990 within the medieval town walls of Southampton. It incorporates a basement requiring construction to between 6–7 m below ground level through fill, brickearth, and water-bearing river terrace gravels overlying mainly laminated clays of the Bracklesham Group. The case record is of particular interest in that the excavation cut-off wall acted as a barrier to the original (that is, pre-excavation) groundwater seepage in the terrace gravels. Observations of the piezometric levels before and after construction confirm ponding on the upstream side of the basement. However, it appears that the pre-construction seepage pattern on the downstream side was modified by the medieval double moats which are known, at least in part, to have been excavated into the terrace gravels.

Abstract
The Bargate Centre is a large, four-storey shopping arcade constructed during 1986–1990 within the medieval town walls of Southampton. It incorporates a basement requiring construction to between 6–7 m below ground level through fill, brickearth, and water-bearing river terrace gravels overlying mainly laminated clays of the Bracklesham Group. The case record is of particular interest in that the excavation cut-off wall acted as a barrier to the original (that is, pre-excavation) groundwater seepage in the terrace gravels. Observations of the piezometric levels before and after construction confirm ponding on the upstream side of the basement. However, it appears that the pre-construction seepage pattern on the downstream side was modified by the medieval double moats which are known, at least in part, to have been excavated into the terrace gravels.
