Integrated Project Delivery (IPD)



A state-of-the-art campus project for over 3,000 employees, the New Builds project was designed to create a modern facility, using a holistic, lean principle, systems approach at Canadian Nuclear Laboratories, in Chalk River, Ontario, with three major construction projects.


At the inception of this project the New Builds Project was known as the largest Integrated Project Delivery (IPD) project in Canadian History and the largest federal project to use mass timber. The three projects are the Business Hub, Logistics Warehouse, and Support Facility. Utilizing the Integrated Project Delivery (IPD) method which combines people, systems, business structures, and practices into a process where collaboration was at the forefront of the delivery and design.


The Support Facility was constructed to replace aging infrastructure and consolidate multiple locations into one centralized location. It is a 2-storey building constructed of mass timber, for a total of 4,884 m2. The buildings were built with efficient structural grids (constructability, furniture, mass timber, services layouts, budget); cost-effective building siting (existing soils conditions, existing facilities, presentations, future expansion); and program efficiencies (shared resources, optimized program placements).
