Bailey Landfill Expansion

Overview
Delivered a design-build landfill expansion for the City of Chilliwack in collaboration with Sperling Hansen Associates, integrating design development and construction to meet strict environmental and performance requirements. Scope included construction of a fully engineered liner system with GCL, HDPE geomembrane, and geotextile protection layers, along with leachate collection infrastructure and subsurface drainage systems. Work also involved precision grading to achieve required liner geometry, modification of existing stormwater infrastructure, and seamless tie-ins to existing landfill systems. The project was executed through close coordination between design and field teams, ensuring constructability, quality control, and efficient delivery of a compliant, fully integrated expansion.
Challenge
Integration with Existing Landfill Infrastructure - Tying new liner systems into an active landfill environment required precise coordination with existing drainage, leachate systems, and stormwater infrastructure.
Our Approach
We carefully sequenced decommissioning of existing systems and coordinated connections to maintain functionality throughout construction. Detailed survey control ensured accurate alignment with existing grades and infrastructure.
Result
Seamless integration of new and existing systems without disruption to landfill operations.
