Two contracts awarded to advance Green Line LRT Maintenance and Storage Facility
Construction continues to progress on the Green Line LRT – SE Project, with two contracts now awarded to continue work on the Maintenance and Storage Facility (MSF), a large, multi‑building complex covering around 26,000 m² (280,000 ft²) over 2.25 hectares (5.58 acres).
The MSF is the heart of day-to-day readiness for the Green Line. It’s where the light rail vehicles (LRVs) will be housed, maintained, and prepared for service, ensuring Calgarians have a safe, reliable ride every time they step on board.
The first contract, awarded to PCL Construction, kicks off the foundational work needed to bring this facility to life. This includes site grading, underground utilities, and building the foundations for all three connected buildings. This work creates the physical base required to support construction of the MSF, which includes a maintenance shop, train storage building, and supporting operations and administration spaces.
PCL started work onsite in late May and is expected to complete the project by the end of this year.
“This work marks a key step in advancing the complex maintenance and storage facility that will support future Green Line transit operations in Calgary. We are excited to be a partner with The City of Calgary and the Green Line team to execute this important initial construction phase of the project,” says Keith Bowers, Manager, Civil Operations, PCL Construction Management Inc.
The second contract, awarded to Supreme Steel LP, delivers the structural steel that will form the primary framework of the MSF's three buildings, marking the start of visible, above‑ground construction. Supreme was the lead fabricator and erector of the Calgary Bow Tower.
Structural steel is a critical milestone, signalling the shift from foundational work to the next phase of construction as the facility begins to take shape above ground. Much of this work will also support skilled trades and fabrication jobs, with opportunities for local workers as the project ramps up over the coming months. 100 per cent of the steel will be fabricated in Canada by an Alberta-owned company.
“Being part of the Green Line means contributing to something that will benefit Calgarians every day. Our team takes pride in delivering the structural steel with care and precision, helping create a facility that will serve the city for generations,” says Rob Tinker, Vice President, Contracts at Supreme Steel LP.
Supreme Steel will begin work in June, with offsite fabrication happening in late summer. Installation of the steel will begin next year.
Once complete, the MSF will function as an integrated operations hub for the Green Line and will include:
- A three‑level maintenance shop
- LRV storage tracks and service lanes
- A train wash and interior cleaning facility
- A body shop for exterior and interior repairs
- Component repair shops and parts storage
- Administrative and operational office space
Together, these spaces will allow LRVs to be serviced, repaired, cleaned, stored, and prepared for daily service, all within one purpose‑built facility.
Awarding these contracts reflects continued momentum on one of the city’s largest and most technically complex infrastructure projects—one that is not only building transit, but also creating jobs, strengthening local expertise, and investing in Calgary’s future. One additional contract for the MSF will be awarded later this year for the main construction of the facility as well as coordination with other contractors supplying specialized equipment and the LRVs.
