Featured Project

North Vancouver, BC
Key Services
  • Excavation and Disposal
  • Soil Stabilization
  • Water Treatment
  • Brownfield Redevelopment

A former shipyard located in North Vancouver, BC, was a large-scale brownfield site with decades of use that had resulted in metals and hydrocarbon contamination. A multi-year environmental clean-up brought the site to a redevelopment stage, now home to 85,000 square feet of commercial, community and residential space. Milestone Environmental Contracting Inc. was awarded the contract to excavate approximately 50,000 tonnes of contaminated soil from the site.

Key Challenges
  • Managing extensive contamination at a site containing historical structures earmarked for preservation and reuse.
  • Navigating formidable logistical hurdles stemming from the site’s location within a bustling market area and preexisting infrastructure and water infiltration issues resulting from excavating at a considerable depth below sea level, mere meters from the shoreline.
Key Solutions
  • Milestone implemented stringent site control safety measures to safeguard the well-being of both workers and the public throughout the remediation process.
  • Executed large-scale remediation efforts focusing on preserving and safeguarding historical buildings onsite.
  • Employed water treatment methods to ensure they met the necessary standards for safe discharge into the marine environment

Project Scope

Remediation work included:

  • Initial topographic survey.
  • Stakeholder consultation and management.
  • Site control in the heart of Lonsdale Quay.
  • Water Treatment for up to 250 gpm of metals and hydrocarbon-contaminated ground water.
  • Excavation and segregation of various contamination levels based on the slice diagram approach.
  • Treat and stabilization of 600 tonnes of soils contaminated with leachable lead.
  • Transport and Disposal of 50,000 tonnes of waste-level metals and hydrocarbons.
  • Removal of historical creosote piles, concrete foundations and metal debris.
