Work has restarted on parts of the 14-mile stretch of twin-bore tunnels between Euston and Hillingdon after a safety shutdown.
A near-miss incident on September 29 prompted the Skanska Costain STRABAG joint venture to launch a full shutdown and safety review. Two workers in a cherry picker basket narrowly escaped being struck by a steel beam while a gantry crane was being dismantled at the Green Park Way ventilation shaft in west London.
The beam clamps on the main beam slid along the beam, causing it to rotate and violently impact the MEWP, which had two operatives in the basket.
The MEWP was seriously damaged, but the operatives were lucky to escape serious injury. Additional safety measures have been introduced, allowing work to resume on the tunnels.
