Scissorsafe cast in void formers were specified by Costain and cast into concrete tunnel sections for National Grid London power. This Project is a joint venture with Skanska on National Grid’s London Cable Replacement Tunnel, a contract worth £200m which would see the construction of a new 33km long, high voltage electricity cable tunnel between Hackney and Willesden (via Kensal Green) and Kensal Green and Wimbledon.

The anchorage points will be utilised by maintenance workers accessing tunnel ducts which involves removing access and floor sections
