Project Scope

• Construction of an engineered soil treatment facility (STF) to accommodate contaminated soil from this contract and future fiscal projects.
• Excavation, loading, trucking and transfer of contaminated soil from km 698 maintenance yard to km 713 for placement of the STF.
• Provision and operation of water treatment plant and equipment to manage accumulated groundwater within the excavations.
• Excavation, loading, transport, placement and compaction of granular backfill material to restore excavation areas.

Key Highlights

• Faced temperatures in the ‐30 to ‐40 degree Celsius range, creating a logistical challenge to maintain worker safety and keep heavy equipment running efficiently.
• Project was located on an isolated stretch of the Alaska Highway – approximately 2 or 3 hours in either direction to reach essential services. Despite these constraints, Milestone was able to complete the project on‐time and on‐budget.
