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.
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.
