4.5.11 Adjacent excavations

The builder shall ensure that foundations are not disturbed by adjacent excavations.

The engineer should consider the influence of drainage and other service trenches on the stability of the complete design.

The minimum clearance between excavations and foundations must not be less than the depth of excavation minus the depth of the structural foundation. Particular attention is needed for excavation below the water table.
