Site work commenced in October 2006 for the installation of crucial ventilation equipment in the Holmesdale tunnels on the M25. The equipment, including Saccardo nozzles, will be supplied by ventilation engineers Hargreaves. A similar contract was completed by the company for the Thames tunnels on the Channel Tunnel Rail Link (CTRL).
