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
