Project Description

This project consisted of relocating a 65LM steel section (895-mm dia.) of a trunk water main in North Delta, B.C.  This was required to both avoid a planned bridge abutment, and to minimize the structural span, and it put the work site in close proximity to the red-coded Norum Creek stream.

As part of the relocation works, a cast-in-place valve chamber was completed with a new butterfly valve. The extremely steep terrain required temporary shoring, including sheet piles and soil anchors.

Our Role

RAM was retained by the joint venture, FTG Constructors, to engage in preliminary design review with Metro Vancouver.  Our team’s responsibilities included:

• Supervising the entirety of the schedule, procurement, and construction phases;
• Ensuring the works remained on budget;
• Working closely with designers to create an outline that permitted minimal shutdown duration of the watermain;
• Navigating and overseeing limited workspace on steep terrain;
• Facilitating double bend tie-ins with welded steel pipes;
• Overseeing hydrostatic testing in an environmentally-sensitive location.
