Design-Build Contracts are best suited to projects of limited scope and complexity. This approach offers the distinct advantage of a shortened project schedule and a less thorough need for design documentation. Since the Scope of Work is defined jointly by the Design-Builder and Owner, any gaps in the Scope of Work and subsequent change orders are either eliminated or minimized. This type of contract is usually performed in two phases with each phase priced separately. The design phase is usually priced as a negotiated fee. During this phase, a proposed design is submitted to the Owner, that he/she reviews and after successive reviews, comments, and modifications, he/she finally approves. In the second phase the construction cost is negotiated, based upon this approved Scope of Work.
