218.150 Built Environment: Design-Build System vs Traditional Approach

This report provides a comprehensive overview of the design-build project delivery system, contrasting it with the traditional design-bid-build approach. Design-build is characterized by a single contract between the owner and a design-builder, integrating design and construction services under one entity, fostering collaboration and streamlining project delivery. The report highlights the advantages of design-build, including single-point responsibility, reduced change orders, and optimized project quality, attributing these benefits to the unified team and coordinated effort from project inception. It also addresses the historical context, noting the shift from the Master Builder concept to specialized roles and the subsequent fragmentation of the construction industry, emphasizing design-build's role in restoring collaboration and teamwork. The analysis underscores that design-build promotes trust, mutual respect, innovation, and creative problem-solving, ultimately delivering projects faster, better, and more cost-effectively. The report concludes by highlighting the importance of a collaborative mindset among all participants for successful design-build projects.

Design-Build is sole-source responsibility.
Design-build is where one entity, the design-builder, enters into a single contract with the
owner to provide both design and construction services.
In all other project delivery systems, there are separate contracts for design and constructio
The single contract for both design and construction is the design-build distinction.

Under the Spearin Doctrine, when the owners give the designer’s documents to the
contractor, they do so with an implied warranty of sufficiency; in essence, a promise by
the owner that the plans and specifications contain information entirely sufficient for
the contractor to bid and build the project.
In all other forms of project delivery, the owner is caught in
the middle of a liability gap.
It is not uncommon under traditional forms of project delivery that the information
provided is not sufficient to bid and build the project. When this happens, disputes,
claims and change orders are often the result, with the owner caught in the middle of the finge

With two contracts, the designer and contractor can easily blame one another for cost overruns
