Trans Mountain aims to minimize disruption to our neighbours during construction. We’ve developed plans for construction activities to reduce noise, light, dust and traffic disruptions.

Noise Mitigation

  • Our studies confirm construction noise will be within acceptable parameters.
  • Some best practices during construction to minimize potential impacts:
    • Enclose noisy equipment and use baffles or shrouds
    • Direct exhaust of noisy equipment away from receptors
    • Noise suppression on heavy equipment
    • Strategically-located sound walls
  • Construction hours will meet requirements outlined in applicable permits and noise bylaws, where practical
    • Typical working hours:  Weekdays 7a.m.-7p.m., Saturday 7a.m. – 7p.m., Work will only take place on Sundays for critical activities (times will vary by region and can be found in the full construction plans)
    • Tunnel boring and Horizontal Directional Drilling (HDD) operations will occur 24/7 as once a drill is started it can’t be stopped till complete
    • Minimized night shifts during construction, with reduced noise-causing activities
  • Pile Driving
    • Limited to daytime shifts only
    • Noise control techniques for in-water pile driving to cut noise at Westridge Marine Terminal
    • Shrouds around pile driving equipment to reduce noise impact

Light Mitigation

  • Directional lighting, diffusion, coating on bulbs and when they’re not being used, we’ll turn off the lights
  • Some lights may be left on during night hours for security reasons

Dust Suppression

  • Maintaining access roads during construction to ensure that dust control measures are in place where warranted
  • Cleaning Equipment prior to leaving construction sites
  • Mud, soil debris or foreign material tracked onto roads will be cleaned as quickly as practical following equipment crossings
  • Re-establish vegetative cover at completed work areas

Traffic Management

Traffic management plans will be developed to minimize disruptions to traffic and neighbours. Our traffic management principles include:

  • working with municipalities to develop plans
  • incorporating traffic count information into designs
  • maintaining pedestrian and bicycle access
  • Consulting residents and municipalities to develop notification plans that may include traffic control, changeable message boards and signage
