Abstract

Design-Build is a project delivery system, mainly used in the construction industry. The method utilizes single source responsibility which differs from the more traditional dual or triple source responsibility format used in Design-Bid-Build. The responsibility is defined by contracts, where the contract in the Design-Build project binds the architect and the contractor under one contract with the project owner. One of the key reasons for doing so is to create a shared responsibility between the architect and the contractor, and thereby involve the architect in the construction phase, and the contractor in the design phase.

Design-Build projects can be further divided into two types; Architect-led Design-Build projects and Contractor-led Design-Build projects. In these cases the Design-Build entity is led either by the architect or the contractor, which affect the management structure and responsibilities in several ways with different pros and cons.

A project delivery system such as Design-Build is essential to project management in construction projects, and especially ties into project procurement management, where a clear definition of the project delivery method is needed. The defining of a project delivery method is a critical deliverable of the procurement strategy as it is defined in the PMI standards for project management. The procurement strategy should define a project delivery method, the contract payment types, and the procurement phases.

Design-Build in construction is most suitable as delivery method when:

Where there is a need to make an early start on site – can overlap design and construction Where the client wishes to minimise their risk – no responsibility for design For technically complex projects which can benefit from the contractor’s expertise Where the employer does not want to retain full control over the design development
