Flatiron JV Selected to Develop Phase One of Calgary’s Green Line Light Rail Transit Project

May 3, 2023

Green Line LRT will provide significant transportation benefits by expanding mobility choice and providing rapid and direct connections between communities, employment hubs and destinations between the southeast and downtown Calgary.

The City of Calgary has selected Bow Transit Connectors – a joint venture including Flatiron – as the Development Partner to deliver Phase One of the transformative Green Line LRT project.

“As part of the Bow Transit Connectors team, we look forward to bringing our expertise in delivering large scale infrastructure projects to enhance Calgary’s future,” said Ken Tanner, Vice President of Canada Operations for Flatiron. “We are proud to share the trust of the City of Calgary as we significantly improve the mobility of the local communities by delivering a reliable, fast transit service while contributing to sustainability by reducing traffic congestion and related emissions.”

Bow Transit Connectors (BTC) is a joint venture between Barnard Constructors of Canada, LP and Flatiron Constructors Canada Ltd; along with WSP Canada Inc. and financial advisor EllisDon Capital Inc. Together, BTC brings extensive experience in underground and above-ground construction, light rail transit design and construction, progressive design and collaborative delivery.

“The selection of our Development Partner and launch of the Development Phase is an important milestone as we move forward with BTC to design, build and finance the Green Line LRT. The Green Line Board has confidence in BTC and their ability to work collaboratively as we collectively ensure we balance costs and risks with the long-term city-shaping benefits of Green Line,” said Don Fairbairn, Chair, Green Line Board.

Flatiron has been awarded a 16-month Development Phase contract in which members of Calgary’s Green Line team and the BTC team will collaborate together to develop the project design and work together to agree on project costs, risk balance, and overall construction schedule before executing a separate project agreement to construct the project.

The overall Green Line LRT project is the largest infrastructure investment in Calgary’s history – with $5.5 billion (CAD) in commitments from Government of Canada, Government of Alberta and City of Calgary. This first phase will include 18 kilometers of dual light rail track, 13 passenger stations, 2 kilometers of underground tunneling, 9 major bridge structures including 1 kilometer of elevated guideway, and a 72-acre maintenance and storage facility. Construction is expected to begin in 2024.

This project strengthens Flatiron’s infrastructure construction portfolio in Canada – adding to the Keating Cross Overpass, Steveston Interchange, Harris Road Underpass and Ruskin Dam projects currently underway. All these projects are consistent with Flatiron’s strategy to build on successful relationships and to secure contracts offering balanced risk profiles and opportunities for enhanced collaboration with our clients.
