BKL Consultants Ltd. has made a significant contribution to the understanding and control of noise and vibration from the Vancouver LRT system. The following projects are underway or were completed by BKL Consultants Ltd.:

Evergreen Line - Environmental impact assessment of the at-grade alignment for the proposed LRT line connecting Coquitlam and Port Moody to the Millennium line at Lougheed Mall.

Canada Line - Acoustical assessment of the alignment for the LRT line (aka RAV Line) connecting Richmond Town Centre, Vancouver International Airport and downtown Vancouver, including construction noise and vehicle noise. Acoustical design for both above ground and underground stations. Assessment and control of underground station ventilation noise.

SkyTrain Millennium Line - Assessment of SkyTrain noise and vibration impact on the Lougheed corridor from Glen Avenue to North Mall, continuing on the Brunette Columbia corridor to Columbia Station. Participation in open houses to provide guidance to the community about SkyTrain noise issues. Design of guideway noise barriers and field testing to confirm their effectiveness.

SkyTrain PMC Line - Assessment of noise impact significance for alternative routes on the SkyTrain extension proposed from Lougheed Mall to Coquitlam Town Centre.

Vancouver/Richmond Rapid Transit Corridor Study - Development of evaluation criteria for community noise impact from three alternative rapid transit technologies (ALRT, Bus and Rail) for several proposed corridors from Vancouver to Richmond.

Gateway Station Noise Study - Evaluation of the significance of acoustical treatment to the ceiling and roof of the proposed Gateway Station (to improve platform communications, and reduce the disturbance potential of rain on the platform roof).

Gateway Station Noise Impact Assessment - Evaluation of the potential impact of the proposed Gateway Station on their Gateway Integrated Development involving both commercial and residential facilities as well as outdoor public malls.

SkyTrain Track Lubricant Study - A study of the acoustical benefits of a proprietary wheel/rail lubricant system.

Numerous studies on the original SkyTrain system from Waterfront to New Westminster Stations including:

• Prediction of Noise and Vibration Levels Adjacent to Proposed ALRT Line
• Dunsmuir Tunnel Vibration Survey
• Vancouver ALRT Baseline Noise and Vibration Survey Measurement Sites
• Noise Control on ALRT Electrical Substation
• ALRT Station Design Manual - Acoustics
• Acoustical Design of ALRT Stations

Residential Developments Adjacent to ALRT Line - BKL Consultants Ltd. has been retained on several occasions to assess the potential effects of ALRT noise on developments proposed for locations close to the right of way.
