Second Narrows Water Tunnel Concrete Works
Project Description
The Second Narrows Water Supply Tunnel project will replace three existing water mains that were installed in 1948, 1954 and 1978. The 1.1km tunnel will cross under the Burrard Inlet from North Vancouver to the City of Burnaby.
QUATTRO'S ROLE
Quattro supplied labor, equipment, and supervision for placing and finishing approximately 2,750m3 of concrete in collaboration with Traylor-Aecon. Joint efforts resulted in optimized work methodologies and concrete mix designs. The project, executed in two lifts, ensured efficient placement and finishing to required tolerances, with approved bulkheads implemented for stability at the end of each shift.
Quattro has provided carpenters and supervision to facilitate the construction of cast in concrete new valve chambers.
