Cableway Rebuild and Relocation for Water Survey of Canada Station at West Aishihik River Near the Mouth, Yukon (08AA011)

Environment and Climate Change Canada (ECCC) maintains cableway and hydrometric gauging stations across approximately 500 sites in the Pacific and Yukon areas. The hydrometric data support activities such as policy development, infrastructure design, water allocation, flood and drought response, recreation, navigation, ecosystem protection, and scientific study. Hydrometric stations typically consist of a “walk-in” or “look-in” instrument shelter,a cableway, or metering bridge to measure discharge. Other structures include helicopter pads and access stairways. Many of the hydrometric stations were built decades ago where structural degradation has occurred over time. As such, infrastructure deficiencies and safety concerns have been identified; requiring repairs and upgrades to return these stations to operational condition. ECCC requires a Contractor to conduct construction activities to remove the existing cableway and construct a new cableway at a new location 600 m upstream, ensuring it meets safety standards suitable for manned operation at the Water Survey of Canada Station, West Aishihik River Near the Mouth, Yukon.
