May 19, 2026, Vancouver, BC, Canada – Knight Piésold Canada has been honoured with an Award of Excellence at the 2026 Association of Consulting Engineering Companies British Columbia (ACEC-BC) Awards for Engineering Excellence for its work on the 1,230 MW Site C Clean Energy Project: Temporary Civil Works Detailed Design and Construction Monitoring.

Recognized in the Energy & Industry category, the award celebrates Knight Piésold’s leadership in delivering technically complex, high-consequence temporary civil works that enabled the successful construction of one of the largest infrastructure and clean energy projects ever undertaken in Canada.

Presented annually, the ACEC-BC Awards for Engineering Excellence recognize outstanding achievements in consulting engineering, highlighting projects that demonstrate technical excellence, innovation, collaboration, and positive community impact. This year’s awards gala took place on May 8, 2026, at the Vancouver Playhouse, bringing together engineering leaders, project partners, and industry stakeholders from across British Columbia.

“The Site C Clean Energy Project  represents more than the successful delivery of a major hydroelectric facility—it demonstrates the critical role that temporary works engineering plays in enabling safe, resilient, and sustainable infrastructure construction,” said Sam Mottram, Managing Principal at Knight Piésold Canada. “We are proud to have supported BC Hydro and Peace River Hydro Partners for more than a decade of project development and construction, helping deliver a project that will provide clean, reliable energy for generations to come.”

Delivering Critical Infrastructure for a Generational Energy Project

Owned by BC Hydro, the Site C Clean Energy Project (Site C project) is a 1,230 MW hydroelectric generating station on the Peace River in northeastern British Columbia. The project generates approximately 5,100 GWh of renewable electricity annually—enough to power approximately 450,000 homes—supporting British Columbia’s long-term energy security and decarbonization goals.

As lead designer for Peace River Hydro Partners (PRHP), Knight Piésold provided detailed design and construction monitoring services for the temporary civil works that enabled safe and efficient construction of the dam, spillways, and generating station. The team’s scope included major cofferdams, river diversions, site-wide water management systems, major excavations, haul roads, quarry developments, roller compacted concrete mix designs, and environmental protection infrastructure throughout the project lifecycle.

Working within an integrated design-construction model, Knight Piésold collaborated closely with BC Hydro, PRHP, regulators, Indigenous representatives, and other stakeholders over 14 years of project development and construction. The project required innovative engineering solutions to address challenging hydraulic, geotechnical, and environmental conditions while maintaining safe construction operations and supporting environmental stewardship objectives.

Supporting British Columbia’s Clean Energy Future

Commissioned in 2025, the Site C project now serves as a major source of renewable electricity for British Columbia, strengthening grid reliability while supporting the province’s transition to a lower-carbon economy.

The ACEC-BC Award of Excellence recognizes not only the project’s technical achievement, but also the sustained collaborative effort required to safely deliver complex infrastructure at a provincial scale.

“This award reflects the dedication, expertise, and collaboration of everyone involved in the Site C project,” added Mottram. “We are honoured to be recognized by ACEC-BC and proud to have contributed to a transformative clean energy project that will deliver lasting value to British Columbians.”

Knight Piésold continues to support major hydropower, mining, and infrastructure projects across the province and around the world, delivering practical engineering solutions that balance technical performance, environmental stewardship, and long-term sustainability.
