Utility Coordination in Alternative Delivery Methods for Transportation Projects: Lessons Learned from In-Market Design Phase (Bid Process)

In large linear infrastructure projects under public private partnership (P3), one of the principal risk contributors are the subsurface utilities impacted that need to be either protected or relocated. In fact, utility relocation may be a significant factor in selecting a preferred construction methods or even dictating changes on design disciplines. The P3 model is designed share risk between private and public entities. This alternate delivery approaches have an accelerated nature with aggressive schedules, where minor utility conflicts can result in significant costs and schedule impacts. The utility coordination task is a key driver and sets the critical path on the schedule. Therefore, early engagement of utility agencies in the project will be crucial, even from the initial planning phase of the project. The use of Transportation Association of Canada (TAC) guidelines and utility relocation procedures are the key elements to a successful project win and delivery.
