Lafarge Rail Spur

Project: Lafarge Rail Spur
Location: Richmond, BC
Client: Hatch Mott MacDonald
A 400-m rail spur was proposed for a railcar storage at the Lafarge #1 Substation in Richmond, BC.  The rail spur is connected to the Canadian National (CN) railway, and splits into two railcar tracks in the storage area. 

The scope of work was to evaluate the foundation requirements for the proposed rail spur.  Additional considerations were given to the presence of concrete tailings, which affect the overall foundation response along the rail alignment.

M+EG was responsible for the following activities:
  • Field investigation consisting of CPT soundings, auger borings and DCPT to evaluate the soil conditions in the virgin area and the segment that has been affected by the concrete tailings.
  • Laboratory testing of the concrete tailings to determine the material’s strength and stiffness properties/parameters.
  • Evaluation of embankment stability and settlements for the rail tracks.
  • Seismic evaluation for the foundation soils.
  • Stability Evaluation for the concrete tailings embankment.

Project Highlights:

  • Assessing the properties of the concrete tailings to estimate the potential differential settlements along the proposed rail spur.
  • Site coordination involving contractors and CN representative to ensure minimal impact to the rail operation and the site work meeting the CN regulations.
