Transportation

The DWB engineering department specializes in transportation and civil projects, including road and highway design, stream crossing design (bridges and culverts), hydrotechnical studies and river engineering, steel and concrete building design, and related services such as materials testing, traffic management planning, quality plan development, bridge inspections and structural and load rating analysis.

DWB provides services for all project phases from feasibility studies, planning and preliminary engineering through to detailed design, tender document and specification development, and through to contract administration, construction supervision, and operational-phase inspections and certification. Interdisciplinary cooperation with DWB environmental and forestry divisions ensures effective, comprehensive project delivery.

DWB is a proud recipient of several Deputy Minister Awards in recognition of our work on Ministry of Transportation and Infrastructure projects in BC, including the Willow River Bridge northeast of Prince George, Nautley Bridge near Fraser Lake, and Emergency Works on Highway 37A east of Stewart.
