Expansion Planning Checklist Part 2: Bidding Process vs. Design-Build


At the beginning of any new construction project, there is much to consider with regard to who is going to take on the project. Traditional design-bid and Design-Build are the two leading methods in the construction industry today. Below, you will learn the differences in the traditional bidding process and the Design-Build route for your next project.

The Bidding Process

Within the traditional construction bidding process, the owner manages two separate contracts. He/she establishes a contract with the builder and the designer. This makes the owner responsible for communicating with and managing the relationship with all parties involved. But there is not necessarily a contractual agreement, relationship, or obligation between the designer and the builder.


While traditional bidding has been around for a long time, design-build has its benefits. Design-Build differs from the traditional method of construction because they use one entity that will bear sole responsibility for both the design aspect and actual construction part of the overall project. For the Design-Build process, the designer and the contractor work together on the project as teammates. According to a recent study about various construction delivery methods at Penn State University, they found that the design-build method has the ability to save six percent on project costs while significantly shortening completion time.

Comparing design-build and traditional construction

One of the most notable differences between traditional construction and the design-build method is the timing of establishing the overall cost of the project. In the traditional method, the cost is established after the bid, right before construction begins. In the design-build method, the cost is established immediately following the preliminary drawings, and right before the detailed drawings.
