This process also permits making early decisions -which have the greatest impact upon cost- in an informed, cost-based environment. Time Savings. Design and construction are telescoped, bidding periods and redesign time are eliminated, and long-delivery components are identified and ordered early in the design process. Therefore, total design-construction time is significantly reduced, which translates into earlier utilization of the completed facility. Dollar Savings. Design and construction personnel, working and communicating as a team, evaluate alternative materials and methods efficiently and accurately. From the outset of the project, both design and construction expertise, are brought to bear upon all components of a project from site work through mechanical and electrical systems. Because cost evaluation is progressively "fed back" into the design process as it proceeds not after design is complete decisions affecting cost and design are continuously optimized. Because the contractor is responsible for both design and construction, cost overruns resulting from design error or faulty coordination are the responsibility of the contractor, not owner. The owner pays only for scope changes, which he initiates. How is a Single Responsibility Contractor Selected? Because it replaces the process of separately selecting a design professional and construction contractor, selection methods for a single Responsibility entity are often a blend of direct professional selection and cost competition. Numerous proposals can be obtained from a wide spectrum of biddersunder a variety of selection approaches: Direct Selection. The design-builder is selected directly by the owner on the basis of such factors as reputation, qualifications, past performance, and prior association. Competitive Negotiation. A number of Single Responsibility contractors are interviewed, with selection based upon comparative criteria such as fees to be charged, recent comparable costs, personnel to be assigned to the project, and scheduling commitments. Cost Competition. When the owner furnishes criteria for the project or requests the bidders to prepare the preliminary design, project cost quotations can be obtained as the basis for contractor selection. This approach places a burden upon the owner to evaluate each proposal carefully to determine the best value, since each bidder will propose different design solutions to meet the criteria. | |||||||
