            Text Figure 14: Footing depth required to prevent undermining or surcharge loading

            Footing bases must be cleaned following mechanical excavation to expose undisturbed materials over the
            full base area. It is essential that the piling contractor have a ‘mud bucket’ or similar device to enable clean
            out of the pile bases.

            If any soil conditions encountered during construction are found to differ from those noted in the geotechnical
            investigation, Tectonic should be notified immediately, and an inspection carried out to determine if changes
            to footing design are required.

            6.4         Retaining Structures
            Design for retaining structures could be carried out using a pressure distribution applicable to the wall type
            and based on the parameters listed in Table 3 overleaf. The values in Table 3 assume that the walls are
            fully drained, and no allowance is included for hydrostatic pressures, construction loading, up-slope footing
            loadings, the effects of sloping ground and backfill compaction stresses.
