Typical excavations have room to safely slope or step the sides of the excavation. But inner-city excavations and last remaining lots in new subdivisions are limited in space and often require straight-cut excavations. OH&S regulation states that if excavation is more than 1.5m deep, the wall needs to either be cut back or a protective temporary structure must be installed. If the excavation is more than 3m deep, the temporary protective structure must be designed by a professional engineer. Unsupported excavations over 1.5m in depth can be shut down by OH&S and city building inspectors.
