In order to delivering the Ontario Line Pape Tunnel and Underground Stations contract, Pape North Connect was chosen by Infrastructure Ontario and Metrolinx.
The progressive design-build contract with C$1-2bn value was concluded as a Development and Master Construction Agreement (DMCA) between consortium and Metrolinx.
The Pape North Connect team includes the construction team of Webuild Civil Work and Fomento de Construcciones y Contratas Canada Ltd; and the design team of Arcadis Professional Services (Canada) Inc and Aecom Canada Ltd.
The DMCA incorporates a multi-stage design process called a development phase, according to the progressive design-build model.
Considering that the development phase allows for a collaborative approach between Metrolinx and Pape North Connect to finalise the scope, risk allocation and pricing of various elements of the contract, the time duration of this stage is almost 24 months, whereas early works construction can start during this phase. Following completion of the development phase, Metrolinx will have the chance to sign a final target-price agreement with Pape North Connect, which would include final agreements on detailed designs and a negotiated price.
While 3km of twin tunnels under Pape Avenue from the Gerrard portal to the Don Valley bridge are the involves of the scope of work; two tunnel portals at Gerrard Avenue and Minton Place; one underground station at Pape Avenue and Danforth Avenue (interchange with the TTC’s existing Pape Station on Line 2) and another underground station at Cosburn Avenue and Pape Avenue; three emergency exit/service buildings; underpinning of the existing TTC Pape Station; as well as a rail switch/crossover in the tunnel near Sammon Avenue are also the contents of this work.
The 15.6km, 15 station Ontario Line project is being delivered through various public-private partnership, progressive design-build and traditional procurement contracts.
