The City of Calgary announced the awarding of a pair of contracts for the Green Line LRT SE project to KLS Earthworks & Environmental and Graham Construction.
KLS has been selected to complete site grading and servicing at the future Maintenance and Storage Facility located just north of 126 Avenue SE between 40 Street and 52 Street SE, while Graham has been awarded the 114 Avenue and Barlow Trail SE piling and road works contract.
“We’re proud to contribute our expertise to a project that will shape the future of transportation in Calgary,” says Chris Powell, COO, KLS Earthworks & Environmental.
“As a local company with deep roots in this city, being part of this project is more than just a job—it’s a chance to help build the infrastructure that will serve our community for generations to come.”
The scope of work to be completed by KLS by the end of November of this year includes stripping and removing the topsoil and rough grading across the site, including the formation of two dry ponds and one wet pond at the west end of the project area. It also includes installing deep utilities including water mainlines, sanitary sewer lines, and stormwater infrastructure.
This work will set the stage for construction of the Maintenance and Storage Facility building, which is where the light rail vehicles will be stored, serviced, cleaned, and maintained. This area will also include Shepard Station, a 920-stall Park and Ride, bus terminals, and a plaza.
“Graham is proud to partner with The City of Calgary to progress the Green Line project. We’re not just building infrastructure—we’re building a more accessible and connected Calgary for everyone that lives and works here,” said Steve Smith, EVP Infrastructure & Industrial.
Graham will mobilize to site in late July to begin this crucial work.
To support the bridge deck and rail tracks, 14 piers will be installed, but for the piers to be built, they need a foundation. To provide this, piling is undertaken, which includes drilling long, column-like holes deep into the ground, which are then filled with concrete and structural reinforcing steel.
For this work to take place, some changes and realignment to the roads in the area are needed. Some of these changes include widening westbound 114 Avenue on the west side of Barlow Trail, widening Barlow Trail south of 114 Avenue, reconfiguring the eastbound turning lane off 114 Avenue to southbound travel on Barlow Trail, and reconfiguring the northbound turning lane off Barlow Trail onto eastbound 114 Avenue.
These reconfigurations are necessary to facilitate construction of larger medians, where the pier structures will go.
The majority of Graham’s work is expected to be finished by December of this year, with some road work to continue in the spring of 2026, including the final top lift of asphalt on the reconfigured roadways.
Work on the remaining construction of the bridge will take place in 2026.
Graham isn’t new to the Green Line project. They are currently wrapping up the 78 Avenue project in Ogden as part of the early works for the Green Line, which included a pedestrian tunnel and vehicle underpass.
