Over the past three years, Trans Mountain has been conducting field studies along the entire proposed corridor to help us assess the route and facilities, and identify the environmental conditions of each area prior to construction.

Geotechnical investigations are an important component of the field studies program and will ultimately help Trans Mountain to plan, design and build the pipeline and new or expanded facilities in the safest way possible, which includes taking into consideration subsurface conditions.

Similar to the work completed in July 2014, Trans Mountain is conducting a supplementary offshore geotechnical investigation at the Westridge Marine Terminal in Burnaby as part of ongoing engineering design for the proposed dock expansion. This work includes geotechnical drilling, soil-sampling and testing boreholes at a number of locations on the south shore of the Burrard Inlet near our existing dock.

The samples will help engineers determine the characteristics of the subsurface conditions and soils to provide more information for the proposed expansion, including determining appropriate foundation designs, construction techniques and mitigating seismic risks.

This type of work is standard and common practice to ensure proper design and construction of above-ground structures, such as residential and commercial buildings and bridges, as well as underground infrastructure.

Trans Mountain is committed to minimizing disruptions caused by these studies to surrounding communities and to avoid any impact to the environment. Neighbours to Westridge Marine Terminal have been notified and all necessary permits have been obtained. This work is scheduled to be completed by the end of February.
