WHS Management for Excavation & Earthworks

Prevent trench collapses and service strikes with engineering controls and compliant safe work methods.

Excavation and earthworks underpin almost every construction project, from residential footings to major civil works. Trench collapse remains one of the most lethal hazards in the industry, with soil weighing over one tonne per cubic metre and capable of burying a worker in seconds. Underground service strikes on gas, electrical and communications assets add further risk that can affect workers and the public. A structured WHS approach covering geotechnical assessment, shoring design and Dial Before You Dig protocols is essential for every excavation project.
