Central LRT Station Rehabilitation and Jasper Avenue Streetscape

Project Overview

The Central LRT is linked to Edmonton’s pedway system with connections to a number of downtown buildings, while Jasper Avenue is Edmonton’s busiest downtown arterial road. This two-part project consisted of structural repair and architectural retrofit of the Central LRT Station and the development of a new streetscape along a section of Jasper Avenue between 100th and 102nd street.

During the first construction season, PCL removed the north portion of Jasper Avenue and excavated half the LRT station, revealing a situation much different than what the contract and as-built drawings depicted. This discovery pushed a major design effort and a 55 percent scope increase to accommodate the numerous underground obstacles, grade discrepancies, structural anomalies, and varying conditions. Since the road construction season in Edmonton is limited to only six months, winter approached quickly leaving little time to design, plan, and construct the infrastructure necessary to accommodate these changes.

The project team developed an approach that utilized staged heating/hoarding of two city blocks, combined with an accelerated working schedule to get the project back on schedule. Work progressed day and night to complete the north side of Jasper Avenue two weeks in advance of the contract milestone. Anticipating a similar scope growth and required redesign on the south side, the project team led the design group through investigative demolition and excavation throughout the winter months to mitigate delays. Accelerated working schedules continued throughout the construction of the south side of Jasper Avenue, ultimately delivering the project to traffic two weeks ahead of the contractual completion date.
