<P> The digital procurement method is rapidly emerging . There are various web sites and applications that provide electronic bidding, tender calls, scope work, designbids, BuildTools and related services . </P> <P> Design - build (or design / build, and abbreviated D-B or D / B accordingly) is a construction project delivery system where, in contrast to traditional "design - bid - build" (or "design - tender"), the design and construction aspects are contracted for with a single entity known as the design - builder or design - build contractor . The design - builder is usually the general contractor, but in many cases it is also the design professional (architect or engineer). This system is used to minimize the project risk for an owner and to reduce the delivery schedule by overlapping the design phase and construction phase of a project . Where the design - builder is the contractor, the design professionals are typically retained directly by the contractor . </P> <P> The design / build delivery system often cites the original "master builder" model used to build most pre-modern projects . Under the master builder approach, a central figure of the architect held total project accountability . From inception to completion, the master builder was the key organizational figure and strictly liable to the owner for defects, delays, and losses . The design / build system is a return to some of the fundamentals of the Master Builder approach . </P> <P> Design - build focuses on combining the design, permit, and construction schedules in order to streamline the traditional design - bid - build environment . This does not shorten the time it takes to complete the individual tasks of creating construction documents (working drawings and specifications), acquiring building and other permits, or actually constructing the building . Instead, a design - build firm will strive to bring together design and construction professionals in a collaborative environment to complete these tasks at the same time . </P>
