This month, I continue to examine the different project delivery methods (PDMs), focusing on why design-build (D-B) and integrated project delivery (IPD) are superior to design-bid-build (D-B-B) or construction management (CM).
Experience has also shown me that D-B and IPD offer enhanced teamwork with quality control (QC) serving as an integral part of both PDMs. D-B-B has very limited QC opportunities, leaving the design team and CM to their own means to maintain in-house QC and not QC teamwork.
