Design - Build

What is Design Build in Construction?

kcs inc 1Designbuild (or design/build, and abbreviated D–B or D/B accordingly) 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 designbuild coThe 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. 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."

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.ntractor.

  • kcs inc 2Efficiency: Typically led by contractors, 'design–build' has evolved as an efficient way to deliver projects primarily where the building project goals are straightforward, either constrained by budget, or the outcome is prescribed by functional requirements (for example, a highway, sports facility, or brewery). Construction industry commentators have described design–build as a high performance 'construction project delivery system', a dynamic approach to making buildings that presents an alternative to the traditional design-bid-build approach.

  • Single-source: Design–build is growing because of the advantages of single-source management: Unlike traditional design-bid-build, it allows for the owner to contract with just one party who acts as a single point of contact, is responsible for delivering the project and coordinates the rest of the team. Depending on the phasing of the project, there may be multiple sequential contracts between the owner and the design–builder. the owner benefits because if something turns out to be wrong with the project, there is a single entity that is responsible for fixing the problem, rather than a separate designer and constructor each blaming the other.
