An unsafe deep excavation with inadequate support and development of cave- in was observed near GH#4 and a MEWP was operating near to the excavation edge where the edge protection provided was not suitable to prevent a potential equipment rollover into the excavation. Also noticed loose materials / stored scaffolding components and boulders on the excavation leading edges and benchings. CMA notified the concerns to TCA JV and advised to rectify the excavation walls and to provide robust barriers on the excavation edges which are exposing to vehicle or equipment movement.
Hazard category: Unsafe excavations
