What characterizes the Design-Bid-Build (DBB) process?

The Design-Bid-Build (DBB) process is characterized by the fact that the design phase is completed entirely before engaging a contractor. In this traditional project delivery method, a designer or architecture firm creates the complete design of the project first, which includes detailed specifications and plans. Once the design is finalized, it is put out to bid, allowing various contractors to submit proposals based on the completed design.

This structure helps ensure that all parties involved have a clear understanding of the project’s scope, costs, and requirements before construction begins. As a result, the bidding process generally focuses on the cost and qualifications of construction teams, leading to competitive pricing for the owner.

In contrast, other methods like collaborative contracting or integrated project delivery involve more interaction and continuous involvement between designers and builders throughout the project lifecycle, which is not a feature of the DBB approach. The DBB process does not typically offer the flexibility in timelines and costs seen in more collaborative methods, nor does it consolidate liability under a single entity, which can often be the case in design-build arrangements.
