Calgary Green Line underground station design concept

CANADA: Two consortia have been shortlisted for a contract to design and build the first phase of Calgary’s Green Line light rail project, covering the 18 km from Shepard to Eau Claire with 13 stops.

They are:

  • Bow Transit Connectors: Barnard Constructors of Canada, LP, Flatiron Constructors Canada Ltd, and WSP Canada;
  • City Link Partners: Aecon Infrastructure Management, Dragados Canada, Acciona Infrastructure Canada, Parsons, and AECOM Canada.

The Green Line board said Phase 1 would be the largest infrastructure project in the city’s history, and would cover the most technically complex section of the line. Future expansion to the north and south is planned for the longer term, which could take the Green Line to 46 km and 29 stops.

The requests for qualification were evaluated against technical capabilities, approach, experience and financial capacity.

A request for proposals is to be released by the end of Q3 2022, with the board aiming to select preferred proponent as the development partner in early 2023. A 12-month development phase would then begin with collaboration and design progression to gain a better understanding of risks and costs.

‘Green Line is confidently moving forward with Bow Transit Connectors and City Link Partners, two very strong proponent teams’, said board Chair Don Fairbairn on July 29. ‘With extensive competition due to record investment in global transit, to have attracted their collective expertise is a great endorsement of the project.’

In 2021 the city of Calgary selected CAF to supply 28 seven-section Urbos 100 low-floor trams to operate the first phase of the Green Line, with an option for up to 24 more.
