The Health and Safety Executive has criticised main contractor Balfour Beatty and engineering consultant Geoconsult in its report on the 1994 Heathrow Tunnel collapse.

The report points to organisational failures and a lax attitude to safety during the project. HSE chief inspector of construction, Kevin Myers, said: “The collapse could have been prevented but for a cultural mind-set that focused attention on the apparent economies and the need for production rather than the particular risks.”
