Featured Project #1 (Spy Hill)

Lafarge North America,
Spy Hill Aggregate Plant
Calgary, Alberta

Lafarge awarded CWA the EPCM contract to replace an existing low capacity plant with a new automated high capacity screening, crushing and washing plant in Calgary. As the prime engineering consultant, CWA was responsible for the project budget and schedule, as well as the civil, structural, mechanical and electrical design.

To reduce the schedule, the project was implemented as a design-build with engineering overlapping construction activities. CWA completed the detailed design of all conveyors and supporting structures as well as the coordination of their fabrication and installation. The design of the structure included the wet screen tower, the crushing tower and the dry screen tower, which supports 18 mix-sized conveyors and three screens.
