Project Description

A four-kilometre section on the South Fraser Perimeter Road Project in North Delta, B.C., was initially founded on relatively solid ground. However, it contained the challenges of having extremely poor access, steep north-facing slopes, and a high volume of ground seepage. Of particular concern were the many historical surficial landslides which would overflow onto the Burlington-Northern Santa Fe (BNSF) rail tracks below.

The project for this single-lane, four-kilometre pioneer road began in late 2010, and took one year to establish access for excavation, wall building and eventually, the delivery of bridge girders. A major milestone was achieved in November 2012 when thirty 50-metre long NU girders were successfully transported into their positions for the permanent bridge crossings.

Our Role

RAM was retained by the joint venture FTG Constructor to provide project management services for construction and technical design review. Some of the unique challenges that our team overcame from this pioneer road included:

• Construction within the clear zone immediately adjacent to active BNSF tracks;
• Crossing 3 red-coded streams and 5 yellow-coded streams;
• Pockets of difficult soil conditions, including peat, clays and high seepage zones;
• Environmental concerns including erosion runoff, along with noise and dust concerns from adjacent residential homes.
