Following Osler’s introductory Progressive Design-Build webinar, there was interest in having a second session covering the project delivery model in more detail. Andrew Wong and Joel Heard, both partners in the Construction and Infrastructure Group, hosted this event, with an in-depth look at how Progressive Design-Build differs from other models.
Pricing is seen as a key difference. In the Traditional Design-Build model, for example, pricing is provided to the owner at the time the construction contract is signed, even though design drawings and specifications have not been fully completed. The builder adds contingency to the contract amount. With Progressive Design-Build, a fixed amount for sub-contract work is not determined until the builder has gone out to tender and the owner has had the opportunity to review the quotes with full transparency. This model thus provides the owner with greater cost certainty and predictability.
With the integrated project delivery model, the designer typically has a seat at the table with the owner while this may or may not be the case with Progressive Design-Build. As well with integrated project delivery, the owner can terminate any time before acceptance of the validation report. This is well before design and procurement take place. With Progressive Design-Build, termination for convenience is not likely to be triggered before the full price, including the amount for sub-contract work, is presented.
Joel Heard explained that the standard CCDC 14 contract can be used for Progressive Design-Build projects, although the contract will likely need to be modified with supplementary conditions and amendments. For example, scoping requirements may need to be modified to accommodate a customized design development process. The procurement process may also need to be addressed in more detail.
