CWA is exhibiting at Minerals North 2017

Posted on 04/11/2017 at 10:09am

CWA will be exhibiting at the Minerals North Conference in Prince George from April 25 to April 27.

The Minerals North Conference is northern British Columbia’s annual gathering of its communities and the mineral industry. A vital forum for bringing together the industry and communities, Minerals North provides a venue for informed and respectful discussion about responsible mineral exploration and development. The event provides an opportunity for local communities to showcase their capacity to service the mineral industry, for community leaders to learn about economic and policy issues that affect the minerals sector, and for the industry to be informed of local issues and community goals. 

CWA will be located at booth #90 on the second floor of the Prince George Conference and Civic Centre. We look forward to meeting with you to discuss how we can support your minerals and mining projects at all stages, from concept development to project completion.

Stacking and Reclaiming System Upgrades

Posted on 09/16/2016 at 8:27am

The Poplar River Power Station is a coal-fired generating station operated by SaskPower, Saskatchewan’s principal electric utility. The power station receives its coal supply from the nearby Poplar River Mine. The power station and the mine have a shared interest in establishing a coal stockpile large enough to sustain plant operations for up to a week.

Poplar River Power Station

Poplar River Power Station

The power station has two generating units with a combined net capacity of 582 MW. At full load, the facility burns 650 tonnes per hour (t/h). The coal arrives at the power station from the mine via a dedicated train and railcar system and is transferred by conveyor to bunker storage inside the plant.

SaskPower engaged CWA to identify and evaluate cost-effective options for upgrades to the existing stacking and reclaiming material handling system to establish a new coal stockpile. The goal would be to maintain an output of 582 MW for up to seven days in the event of unplanned interruptions to coal supply. The stockpile would also provide the mine greater flexibility to perform track maintenance while allowing the power station to schedule longer periods of maintenance on critical equipment with limited downtime.

Mill Infrastructure Integrity Services

Posted on 09/07/2016 at 2:03pm

Agrium’s Vanscoy Potash Operations (VPO) mill has been in operation for nearly 50 years and currently produces 2 million tonnes of potash per year. As potash is a corrosive product, inspection and repair of existing infrastructure is a top priority to ensure the continued safe operation of the facility and extend the service life of the mill.

Agrium Floor Repairs

Agrium produces, markets and distributes nitrogen, phosphate and potash products for agricultural and industrial customers around the world.

CWA has been involved with Agrium VPO’s mill infrastructure integrity program for several years, beginning with a major project for the inspection and repair of the wet milling facility in 2013. CWA conducted a structural review and repair design for the retrofit of the existing concrete floor systems in the building to provide an additional 20-year lifespan to the mill.


CWA completed inspections of steel, concrete and composite systems on each floor of the building. Representative thickness measurements on structural steel members identified levels of corrosion, and concrete sounding identified delamination. CWA coordinated the removal and testing of samples from the concrete floor.

Fraser Surrey Docks LP (FSD) is the largest multi-purpose deep sea marine terminal on the west coast of North America. With increasing demand for bulk commodity movements through the Port of Vancouver, FSD was granted a permit to build a 4 MTPA coal export facility that would allow coal to be transferred directly from rail to ocean-going vessels or barges.

Located within the Port of Vancouver, Canada’s largest port, FSD has direct access to three Class 1 rail lines: Burlington Northern Santa Fe, Canadian Pacific Railway and Canadian National Railway, and direct deep sea vessel access to the Pacific Ocean via the Fraser River.

As Prime Consultant for the project, CWA assisted FSD with the development of the initial concept, detailed engineering drawings and associated documents for permitting and development of the facility, as well as the capital and operating cost estimates and construction schedule.

Moving the primary crusher into position

Teck Highland Valley Copper Operations, located near Kamloops, BC, is the largest open pit copper mine in Canada. To facilitate the future expansion of the Valley Pit, existing primary crusher #4, and the associated overland conveyors and infrastructure required relocation.

CWA Engineers was engaged by Teck to develop the preliminary construction execution plan, capital cost estimate and detailed design for the relocation. The project also required refurbishment of the crusher hopper, crusher maintenance gantry crane modifications, a new proportional feed transfer tower and a new stand-alone electrical room. During the detailed design phase CWA worked closely with Teck to develop a construction schedule that could be integrated into mine operations to minimize required shutdowns of key equipment to complete the construction and commissioning of both the new and relocated systems.
