South Shore Corridor Project

The South Shore Corridor Project is a high-priority infrastructure improvement project being delivered by Port Metro Vancouver, with funding partners Canadian Pacific Railway, Canadian National Railway, and Transport Canada under the Asia- Pacific Gateway and Corridor Initiative (APGCI). The project involves constructing an 800 m elevated roadway along Stewart Street while maintaining port operations and extremely high volumes of rail and truck traffic. The elevated roadway will eliminate 10 at-grade road/rail crossings and provide a reliable and continuous road connection for truck traffic to port terminals. Collings Johnston Inc. (CJI) is providing project management for the design and construction of the South Shore Corridor Project. CJI has also been retained for

similar services on other APGCI projects including the Roberts Bank Rail Corridor Program, which includes eight road/rail grade separations, and the Powell Street Overpass Project, a road overpass of the Burrard Inlet rail line in downtown Vancouver.

Nechako White Sturgeon Recovery Initiative

The Nechako River at Vanderhoof, BC, is a known spawning and rearing area for white sturgeon. The sturgeon population has undergone a recruitment failure and is now recognized as endangered by the provincial and federal governments. Changes in the river morphology and substrate characteristics have been hypothesized as probable causes for the recruitment failure. As part of the Nechako White Sturgeon Recovery Initiative, the condition of the substrate in the Nechako River was examined. NHC developed an extended freeze core program that enables samples of the substrate to be collected from an anchored boat using liquid nitrogen. Observations from the field sampling program are being used to help the Ministry of Forests, Lands and Natural Resource Operations develop a spawning habitat restoration program for the endangered sturgeon. Client: Ministry of Forests, Lands and Natural Resource Operations. Engineering/geoscience consultant: Northwest Hydraulic Consultants. Boat Support: EDI.

Prince George Pulp Filtrate Pumps Upgrade Two filtrate pumps at the Prince George Pulp Mill were replaced with higher efficiency pumps with a better hydraulic fit to the application. The installation of variable- frequency drive controls on the pumps allowed removal of the existing control valves. Together with improved piping design, these measures reduced energy consumption by approximately 94% or 1.67 GWh/year and provided substantial improvements in maintenance. The electrical energy savings were sufficient under the BC Hydro TSR Incentives Program to fully fund the project. Owner: Canfor Pulp L.P. Design: Andritz Automation, Allnorth Consultants.
