Design–build (or design/build, and abbreviated D–B or D/B accordingly), also known as alternative delivery, [1] is a project delivery system used in the construction industry. It is a method to deliver a project in which the design and construction services are contracted by a single entity known as the design–builder or design–build ...
Design–bid–build (or design/bid/build, and abbreviated D–B–B or D/B/B accordingly), also known as Design–tender (or "design/tender"), traditional method, or hardbid, is a project delivery method in which the agency or owner contracts with separate entities for the design and construction of a project.
Design–build–finance–operate-maintain (DBFOM) [10] [11] also referred to as Design–build–finance–maintain-operate (DBFMO) [12] [13] is a project delivery method very similar to BOOT except that there is no actual ownership transfer. Moreover, the contractor assumes the risk of financing until the end of the contract period.
The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
If speed is important, design and construction contracts can be awarded separately; bidding takes place on preliminary plans in a not-to-exceed contract instead of a single firm design-build contract. The major problem [11] with design-build contracts is an inherent conflict of interest. In a standard contract the architect works for the owner ...
The fast-tracking of the project is therefore achieved through the integration of design and construction phases. Fast-track is more difficult to manage than the traditional design–bid–build process. It requires detailed knowledge of the process, effective planning, integrity and close coordination among the organizations executing the work.
The contractor is able to build their price for the works during the process, in consultation with the client and designer. [ 1 ] As the ability of parties to affect project cost and programme is greater in the design stages than in the construction phase then the potential for value engineering is greater under ECI contracts than traditional ...
Performance-Based Building Design is an approach to the design of any complexity of building, from single-detached homes up to and including high-rise apartments and office buildings. A building constructed in this way is required to meet certain measurable or predictable performance requirements, such as energy efficiency or seismic load ...
