As On-Corridor Works is a complex regional project with multiple external interfaces, stakeholders, utility and operational elements, it is being delivered as a Progressive DBOM (design-build-operate-maintain) model.
In a
Progressive model, the project features a collaborative approach between the project owner and the contracting partner. Before the project’s contractual schedule and price can be finalized, the parties will enter a Development Phase – a multi-stage design process, whereby Metrolinx as project owner, and ONxpress as contracting partner, work closely together to finalize the scope, risk allocation and pricing of various elements of the project. The magnitude of On-Corridor Works requires a two-year Development Phase to progress the design and construction of any early works for the project. Contract cost and schedule will be shared publicly once this phase is completed in 2024. In the meantime, project details, community consultations and other important updates during this time will be posted to Metrolinx’s website.
