The term "Design Bid Build" (DBB) is often associated with the construction industry, describing a traditional project delivery system. It's one of the most commonly used methods in the sector, due to its simplicity and widespread understanding. But what exactly does Design Bid Build entail, and how does it differ from other project delivery methods?
In a Design Bid Build project, the owner, client, or developer engages with different professionals sequentially. The process begins with the design phase, followed by the bidding process, and finally, the construction or build phase. Here's a comprehensive look into this method, its advantages, disadvantages, and steps involved, to help you understand if it's the right fit for your next project.
The Design Phase
The design phase is the initial and arguably the most critical stage in the Design Bid Build process. It involves creating detailed drawings and specifications for the construction project. These designs must comply with building codes, accessible standards, and zoning regulations.
During this phase, the owner or developer engages with architects and engineers to create comprehensive designs that meet the project's requirements and budget. Here are two key aspects of the design phase:
Design Professionals
The Design Bid Build method typically involves separate engagements with architects, structural engineers, mechanical engineers, electrical engineers, and other specialty consultants. Each brings their expertise to create a cohesive and functional design.
This multidisciplinary approach ensures that the design integrates various systems and components effectively. However, it also means the owner or developer must manage multiple contracts and ensure seamless collaboration among these professionals.
Design Development
Design development involves refining and detailing the initial concept. It includes creating floor plans, elevations, sections, and details. During this stage, the design team considers factors like energy efficiency, sustainability, and long-term maintenance.
At the end of the design phase, the owner or developer should have a comprehensive set of construction documents, including technical specifications. These documents serve as the foundation for the bidding process.
