KCB Wins 2023 CEA Award of Excellence

March 21, 2023

Klohn Crippen Berger (KCB) received an Award of Excellence in Transportation Infrastructure for the Spray Lakes Road Coal - Mine Void Risk Mitigation project at the Consulting Engineers of Alberta (CEA) Showcase Awards Gala on March 17, 2023.

About the Project

As part of Alberta Transportation (AT)’s Geohazard Risk Management program (GRMP), which manages approximately 500 geohazard sites along the province’s highways, a large coal mine void was identified that appeared to be expanding upwards towards the highway. Klohn Crippen Berger developed a design that mitigated the risk and ensured early detection of future deformations below the highway. Construction completed in 2021 and it was the first coal mine void backfilling project completed by the AT GRMP program.
