Design-Build is the preferred method for the majority of direct digital control (DDC) contracts. The contractors’ expertise is such that they can deliver the latest, cutting-edge technology faster and more economically. Design-Bid-Build projects may require months or even years to develop construction documents to release for bid, and the DDC systems specified may be outdated before the project is bid. Since the general contractors are in control of the subcontractors, it gives the general contractors the ability to manage the DDC costs and keep the project within budget. The contractors are developing budgets instead of designers; therefore, the likelihood of cost increases and budget delays are reduced. Design-Build and Design-Bid-Build projects are both commissioned in the same way to ensure that the Owner Project Requirements (OPR) are met. The contractor is responsible for developing the most cost-effective solution to meet the project needs which relieves this burden from the owner. For these reasons, it is imperative that DDC contracts be delivered in the Design-Build manner.
