For owners considering collaborative delivery approaches for water and wastewater projects, such as progressive design-build (PDB) or construction management at-risk (CMAR), one of the biggest impediments to acceptance is the perception that the final cost of the project would be larger than a traditional design-bid-build and cannot be controlled. Based on our research, there are two primary reasons this stumbling block exists. One relates to the owner’s belief that their initial cost estimates are correct and that the project can be designed and constructed within their budget. A second, and perhaps more important issue, is that many owners still do not understand how the collaborative process evolves and how to reach a final acceptable price on the project, primarily because they are only familiar with the design-bid-build pricing process that uses the low-bid approach.
