These are either roll-over protective structures (ROPS), falling object protective structures (FOPS) or both, depending on the application. PCBUs must manage all health and safety risks with excavation work. This may lead to structural failure, or ground collapse depending on the site’s ground conditions. Pit excavations are usually four-sided and deeper than the narrowest horizontal dimension at the surface. Making our street lights more energy-efficient. a process to reduce the risk of unforeseen ground conditions. Is the supervisor making sure that no-one climbs on the timbering? If this is not reasonably practicable, PCBUs must minimise the risk by one or a combination of the following: If risk remains, it must be minimised by implementing administrative controls, so far as is reasonably practicable, for example by installing warning signs near the excavation.

On sites requiring multiple schemes or different temporary works disciplines, one competent person may not have experience across all the disciplines of temporary works and may require additional technical support on site. Slide-rail shoring may be used as an alternative to interlocked sheet-pile and H-pile shoring. Self-propelled rubber-tyred scrapers can excavate and haul very large quantities of material economically over long distances at relatively high speed.
