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 as delivery method in construction projects is most suitable when:

• Early on site construction is needed, making design and construction phases overlap
• The client wishes to minimise their risk – no responsibility for design
• The project is technically complex and can benefit from the contractor’s expertise
• Where the owner does not want to retain full control over the design development

Big Idea

Choosing the right project delivery method

Before choosing a project delivery method is is important that the owner of the project is aware of the different methods that are available, and thoroughly understand for which project types each method is the most applicable, as well as pros and cons for each method. Some of the most commonly used methods used in construction are listed below, but not elaborated upon in this article.

Project delivery methods

• Construction Management at Risk
• Design-Bid-Build (also called traditional)
• Design-Build
• Multi-Prime
