In the past, Alberta Infrastructure and Alberta Transportation have used the traditional procurement model (design/bid/build model) to deliver priority infrastructure projects for government-supported and government-owned infrastructure. In this model, the government generally funds 100 per cent of the facility either by providing a capital grant to the SIO (partial funding, for post-secondary institutions) or by making progress payments for its own infrastructure. This traditional approach involves extensive design work before the project is procured and there is limited project-related risk transferred to a private contractor. Formal sets of guidelines and procedures are used throughout the three-stage process of planning, designing and implementing.
