{{Short description|Construction project delivery system}} {{More citations needed|date=January 2011}} '''Design–build''' (or '''design/build''', and abbreviated '''D–B''' or '''D/B''' accordingly), also known as '''alternative delivery''',<ref name="altdelivcodot">{{cite web |title=Alternative Delivery Program - Design-Build & Contract Manager / General Contactor |url=https://codot.gov/business/alternativedelivery |website=[[Colorado Department of Transportation]] |access-date=January 23, 2023}}</ref> is a [[Project delivery method|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 contractor'''. It can be subdivided into '''architect-led design–build''' ('''ALDB''', sometimes known as '''designer-led design–build''') and '''contractor-led design–build'''. In contrast to "[[design–bid–build]]" (or "design–tender"), design–build relies on a single point of responsibility contract and is used to minimize risks for the [[project owner]] and to reduce the delivery schedule by overlapping the design phase and construction phase of a project. Design–build also has a single point responsibility. The design-build contractor is responsible for all work on the project, so the client can seek legal remedies for any fault from one party.<ref>"Construction Contracts: Law and management" by John Murdoch and Will Hughes, published in 2007 by "Taylor & Francis E-library", fourth edition, United Kingdom {{ISBN|0-203-96574-4}} simultaneously published in USA {{ISBN|978-0-415-39368-3}} and Canada {{ISBN|978-0-415-39369-0}}</ref> The traditional approach for construction projects consists of the appointment of a designer on one side, and the appointment of a contractor on the other side. The design–build procurement route changes the traditional sequence of work. It answers the client's wishes for a single point of responsibility in an attempt to reduce risks and overall costs. Although the use of [[Subcontractor|subcontractors]] to complete more specialized work is common, the design-build contractor remains the primary contact and primary force behind the work. It is now commonly used in many countries and forms of contracts are widely available. Design–build is sometimes compared to the "master builder" approach, one of the oldest forms of construction procedure. Comparing design–build to the traditional method of procurement, the authors of ''Design-build Contracting Handbook'' noted that: "from a historical perspective the so-called traditional approach is actually a very recent concept, only being in use approximately 150 years. In contrast, the design–build concept—also known as the "master builder" concept—has been reported as being in use for over four millennia."<ref>"Design-Build Contracting Handbook", by Robert Frank Cushman & Michael C. Loulakis, published in 2001 by Aspen Law & Business, USA {{ISBN|0-7355-2182-4}}</ref> Although the [[Design-Build Institute of America]] (DBIA) takes the position that design–build can be led by a contractor, a designer, a developer or a joint venture, as long as a design–build entity holds a single contract for both design and construction, some architects have suggested that [[architect-led design–build]] is a specific approach to design–build. Design-build plays an important role in [[pedagogy]], both at universities and in independently organised events such as [[Rural Studio]] or [[ArchiCamp]].
