Plans to extend Ottawa’s existing north-south light-rail line further south to the airport and into Riverside South cleared a major milestone this week after the city prequalified three construction and engineering consortiums to bid on the $535 million project.
The prequalified consortiums are:
Trillium Link, consisting of Acciona, Fengate, CAF, CIMA+, Momentum, Thomas Cavanagh, Cobalt Architects and GRC Architects;
Trillium Extension Alliance, consisting of Plenary, Colas, R.W. Tomlinson, Plan Group, WSP, Bird Construction, Mass Electric); and
TransitNEXT, consisting of SNC Lavalin.
Two other consortiums responded to the city’s request for qualifications but were not invited to the next stage to respond to a full request for proposals.
The O-Train Trillium Line extension involves adding 12 kilometres of new rail and seven new stations, including a three-kilometre spur line to the airport. The city is looking for a consortium that will design, build, finance and maintain the infrastructure and train vehicles through to 2048.
It’s one of two major rail procurements underway in Ottawa. Last month, city officials prequalified three consortiums to bid on the $2.5 billion extension of the east-west Confederation Line.
The city says it expects to award contracts for both projects by mid-2018, with the bulk of construction to start in spring 2019.
