Bundling or bringing together enough schools to make it a large enough project was one of the elements considered in the P3 process. As people mentioned previously, it needs to be a certain size because of the complexity of the contractual arrangements and the legal documentation.
The previous speaker mentioned that it is really an issue for the general contractors. You need to get a general contractor that is large enough to handle that volume of work.
In our particular case, the bundling of the projects was also able to incur some economies of scale and some efficiencies in design, because we repeated the design several times for several different schools. We achieved economies of scale by having a large enough project that made it worthwhile.
That was a departure from previous projects, where schools would be one-off. By getting a large enough project, we were able to actually get the economies of scale. In Edmonton Public Schools, for example, the six schools we built under our ASAP 1 program were identical designs. That was responsible for a significant amount of risk reduction and cost savings because of economies of scale.
