Tender: Kingsway Tunnel — Removal of Asbestos-Backed Dado Panels and Redundant Cabling (North & South Tubes)

About

Client is seeking a contractor to remove Asbestos Insulating Board backed dado panels from the walls of the North and South tubes of Kingsway Tunnel. The scope covers approximately 8,100 panels (about 7,433 linear metres and 15,237 m²), each weighing ~61 kg for a total of ~498,248 kg (circa 498 tonnes); all panels carry unique identifying numbers. The works include removal of redundant equipment and aluminium cabling located behind the panels (four cables per lane, two lanes per tube, equating to approximately 38 km of cable, noting some cabling has already been removed), thorough cleaning of exposed surfaces behind the panels, and sealing/encapsulation of asbestos-containing caulking to expansion joints (exposed joints are expected only at the Liverpool end on exposed cast iron sections). The Client must provide evidence that cable and equipment are redundant prior to removal; the Contractor is responsible for programming those confirmations and must notify the Client at least 4 weeks in advance if additional isolations are required.
