When considering which project delivery method to use, homeowners need to assess project requirements, complexity, their desired level of control, and their own preferences to determine whether the traditional Design-Bid-Build approach or the more collaborative Design-Build method is more suitable. Design-Bid-Build (DBB) and Design-Build (DB) are two commonly used project delivery methods. It is important to understand their difference to help homeowners determine their path toward their home renovation.
1. Design-Bid-Build (DBB): The DBB method follows a step-by-step approach to construction projects. It involves the following three distinct phases:
• Design phase: In this phase, an architect will develop the project’s design, including drawings, specifications, and construction documents. The design is typically completed before any construction work begins.
• Bid phase: Once the design is finalized, the owner solicits bids from multiple contractors through a competitive bidding process. Contractors review the project’s plans and specifications and submit their bids or cost estimates for the construction work.
• Build phase: After the bidding process, the owner selects the contractor with the most favorable bid, usually based on factors such as cost, experience, and reputation. The chosen contractor then proceeds with the construction phase, executing the project as per the provided design and specifications.
Key characteristics of the Design-Bid-Build approach include a clear separation of design and construction responsibilities, competitive bidding for contractors, and a rigid sequence of phases.
2. Design-Build (DB): The Design-Build method offers a more collaborative and streamlined approach to construction projects. It involves the integration of design and construction services into a single entity, typically a design-build firm or a contractor with in-house design capabilities. The process includes the following key elements:
• Design and construction integration: In the Design-Build approach, the design and construction teams work together from the very beginning of the project. This collaboration allows for early input from the construction team during the design phase and builds an appropriate budget.
• Single-point responsibility: The design-build entity assumes overall responsibility for both the design and construction aspects of the project. This streamlines communication reduces potential conflicts, and provides a single point of contact for the owner throughout the project.
• Concurrent design and construction: Unlike the sequential approach of DBB, Design-Build projects often involve overlapping design and construction phases. This allows for a faster project delivery timeline as construction can begin before the entire design is fully completed.
• Flexibility and innovation: The Design-Build method encourages innovation and flexibility, enabling the design-build team to propose alternative solutions or value-added ideas during the project. This adaptability helps address challenges and optimize the project’s outcome.
The Design-Build method offers benefits such as improved communication, faster project completion, potential cost savings, less administrative burden for the owner, and increased opportunities for innovation.
Here at LHS, we implement the design-build method. We believe in lessening the workload for the homeowner while also allowing more opportunities for input. This also ensures we are your main point of contact for any questions or concerns you may have along the way. Call today for a free consultation on your next home project (734) 270-6960.
