Project Life Cycle

Design

The first step in designing a capital project is figuring out what needs to be built and what limitations exist. Project design can begin prior to procurement and continue once a contractor has been selected. 

Metrolinx considers many important factors when delivering our transit projects, including safety and accessibility for our customers, how the project will operate and be maintained, as well as its sustainability and longevity over time. The initial design phase typically involves multiple teams and stakeholders, and the goals and objectives of the project are outlined.  

The next step focuses on developing the detailed design throughout and after the procurement stage.  

Depending on the project, design proposals from third party contractors are received. These proposals include their proposed plans for how they would deliver the project for us. We then review the proposals to ensure they conform to our established project requirements and goals.  

The way we approach design activities varies depending on the chosen procurement delivery model, and what is required of the project to meet the needs of our customers and deliver the benefits to the community. The final project design is then built during the construction phase.
