Excavation breaches on the rise

12 Jan 18 A construction safety organisation has identified a spike in unsafe excavation work on UK construction sites.

The Building Safety Group (BSG) has reported a 16% rise in ‘excavation work’ breaches on construction sites in the fourth quarter of 2017.

BSG’s figure is based on approximately 11,000 independent inspections that it conducted for the construction industry over a six month period, comparing Q4 with Q3 in 2017.

Injuries resulting from excavation trench collapses can often be severe and sometimes fatal. Last year the director of a housing development company, Conquest Homes, was jailed for gross negligence manslaughter after a ground worker was crushed to death in a building site trench. Another company undertaking excavation work was fined for safety breaches when a worker was burned after striking underground electrical cables. Mason Construction (London) Ltd pleaded guilty to breaching Regulation 13(1) of CDM regulations 2015 and was fined £25,000.

Paul Kimpton, managing director of the Building Safety Group, said: “These types of injuries can be prevented if companies implement safe methods of working and provide the necessary information and training for workers. Excavations must be properly planned, managed and monitored to ensure no one enters an excavation deeper than 1.2 metres, without adequate controls in place to prevent a collapse.”

He added: “Without suitable support, any face of an excavation will collapse; it’s just a matter of when. The steeper and deeper the face, the wetter the soil, the sooner the collapse. Trenchless technologies are available which will help to avoid many of the hazards of excavation but, if a trench is required, modern approved systems can allow the ground support to be installed without the need to enter the excavation.”
