Interlink Logistics Park – Site Grading & Underground

Client:

Interlink Logistics Park

Location:

Rocky View County, Alberta

Project Scope

The Interlink Logistics Park project saw Whissell serve as Prime Contractor for the full civil development of an industrial and commercial subdivision. The scope encompassed both earthworks and complete underground utility installation, delivering the site from raw ground to a fully serviced, development-ready condition. Primary earthworks operations involved significant rock excavation and processing challenges across the site footprint, while the underground scope included the installation of storm sewer, sanitary sewer, and watermain infrastructure to service the park. In addition to primary grading and utility operations, the scope included erosion and sediment control, stormwater pond management, and the excavation and disposal of loam to prepare the site for future building and road construction.

Earthworks:

  • Rough grading for industrial and commercial subdivision including significant rock excavation
  • Controlled blasting and mechanical breaking of rock formations; on-site processing for granular reuse
  • Erosion and sediment control; stormwater pond management
  • Excavation and disposal of loam; site preparation for future building and road construction
  • Rock management plan sequencing blasting to minimize vibration impacts on adjacent properties

Underground:

Storm sewer main installation including catch basins, manholes, and outfall connections

  • Sanitary sewer installation with manholes and lot service connections
  • Watermain installation including valves, hydrants, and service connections
  • Trench excavation, shoring, bedding, and backfill through rock and mixed soil conditions
  • Surface restoration and reinstatement upon completion of underground works

Challenge & Mitigation

The presence of substantial rock formations required controlled blasting and mechanical breaking across the site, creating a dual challenge of managing vibration impacts on adjacent properties while maintaining progress on the underground utility installation program running concurrently. Whissell's team developed a rock management plan that sequenced blasting operations around active trenching windows, processed excavated rock on-site to produce usable granular material for road subgrade and pipe bedding, and coordinated disposal of unsuitable material to keep both the earthworks and underground programs advancing in parallel without schedule conflict.

Value Add Solution

By self-performing both the earthworks and underground utility scopes under a single contract, Whissell eliminated the coordination risk and schedule gaps that typically arise when these disciplines are split between contractors. Processing excavated rock on-site and converting it to usable granular material for pipe bedding and road subgrade significantly reduced the volume of imported aggregate required and minimized off-site disposal costs, delivering measurable savings to the client while keeping the full civil program on schedule.
