HS2 joint venture fined £400,000 following serious excavation site incident

An HS2 construction contractor has been fined £400,000 after a tipper truck overturned into an excavation at a west London worksite, leaving the driver with multiple injuries.

The incident occurred in July 2021 at the Copthall North site near Uxbridge, where SCS Railways was delivering a cut-and-cover tunnel for the high-speed railway.

A 20-tonne tipper truck carrying excavated material slipped from the edge of an excavation ramp, falling around two metres onto its side and trapping the driver. He sustained a broken nose, shoulder injuries and cuts to his hand.

An investigation by the Health and Safety Executive (HSE) found the accident followed changes to the site's traffic management arrangements that had not been adequately planned or communicated. Inspectors identified a lack of edge protection, missing directional signage and unsupported excavation faces alongside vehicle routes.

The HSE concluded that suitable physical barriers should have been installed to prevent vehicles from leaving the excavation ramp and criticised failures in the management of revised haul routes.

SCS Railways admitted breaching the Health and Safety at Work Act and was fined £400,000 at Uxbridge Magistrates' Court. The company was also ordered to pay £8,974 in prosecution costs.

HSE Inspector Gordon Carson said the project had detailed procedures for excavation works but failed to safely manage changes to vehicle movements, warning that the consequences of the incident could have been far more severe.
