Design-bid-build
Definition
Primary Definition: Design-Bid-Build is a traditional project delivery method where the design and construction phases are separate. The owner first hires a designer to create the project plans, then solicits bids from contractors to execute the construction based on those plans.
Secondary Definition: This method allows for a clear delineation of responsibilities, with the designer focusing on the creative and technical aspects while the contractor manages the construction process, ensuring that each phase is distinct and well-defined.
Key Components
Design Phase: This initial phase involves the development of detailed project plans and specifications by the architect or designer. It includes conceptual designs, design development, and final construction documents.
Bidding Phase: Once the design is complete, the project is put out for bids. Contractors review the plans and submit proposals, allowing the owner to select a contractor based on price, qualifications, and experience.
Construction Phase: After a contractor is selected, the construction phase begins. The contractor is responsible for executing the project according to the design documents, managing labor, materials, and timelines.
Contractual Relationships: In Design-Bid-Build, the owner has separate contracts with the designer and the contractor. This clear separation helps define roles and responsibilities, reducing potential conflicts.
Project Timeline: The timeline for a Design-Bid-Build project is typically linear, with each phase completed before the next begins. This structure can lead to longer overall project durations compared to other methods that allow for overlapping phases.
Benefits
Clear Project Scope: The Design-Bid-Build method provides a well-defined project scope from the outset. With detailed plans created during the design phase, all parties understand the expectations and requirements, reducing the likelihood of misunderstandings.
Competitive Bidding: This approach allows multiple contractors to bid on the project, fostering competition. This can lead to better pricing and options for the owner, as contractors strive to offer the most attractive proposals.
Cost Control: By separating the design and construction phases, owners can better manage costs. The fixed price from the contractor helps in budgeting, and the detailed plans minimize unexpected expenses during construction.
- Defined Roles and Responsibilities: Each party in the Design-Bid-Build process has clear roles. The designer focuses on the creative and technical aspects, while the contractor handles the construction. This clarity helps streamline communication and accountability throughout the project.
Examples of Design-Bid-Build
Residential Example
A recent project involved the construction of a custom home in the suburbs. The homeowners engaged Studio Carney to design their dream residence, focusing on open spaces and natural light. After completing the design phase, we invited several contractors to bid on the project. The selected contractor executed the construction, adhering closely to the detailed plans, resulting in a beautiful home that met the clients' expectations.
Commercial Example
For a new office building in downtown, we utilized the Design-Bid-Build method to ensure clarity and efficiency. After developing comprehensive design documents, we solicited bids from multiple contractors. The chosen contractor completed the project on time and within budget, creating a functional and modern workspace that enhances productivity.
Educational Example
In designing a new community center for a local school district, we followed the Design-Bid-Build approach. The design phase included input from educators and community members to ensure the space met their needs. Once the plans were finalized, we facilitated a competitive bidding process, ultimately selecting a contractor who delivered a high-quality facility that fosters learning and collaboration.
How We Implement Design-Bid-Build at Studio Carney
At Studio Carney, we embrace the Design-Bid-Build method to ensure a structured and efficient approach to project delivery. Our process begins with a thorough consultation to understand the client's vision and requirements.
During the design phase, we collaborate closely with clients to create detailed plans that reflect their needs while adhering to local regulations and sustainability practices. This phase includes multiple iterations and feedback sessions to ensure the design aligns perfectly with the client's expectations.
Once the design is finalized, we move into the bidding phase. We prepare comprehensive bid documents and invite qualified contractors to submit proposals. Our team carefully evaluates each bid, considering factors such as cost, experience, and project timelines, to select the best contractor for the job.
In the construction phase, we maintain open lines of communication with both the contractor and the client. Regular site visits and progress updates ensure that the project stays on track, and any issues are addressed promptly. Our commitment to quality control and adherence to the original design helps deliver a successful project that meets the client's vision and budget.

Frequently Asked Questions
What is Design-Bid-Build?
Design-Bid-Build is a traditional project delivery method where the design and construction phases are separate. The owner first hires a designer to create detailed plans, then solicits bids from contractors to execute the construction based on those plans.
How does Design-Bid-Build differ from other project delivery methods?
Unlike methods such as Design-Build, where a single entity handles both design and construction, Design-Bid-Build separates these roles. This can lead to clearer accountability but may also result in longer project timelines due to the sequential nature of the phases.
What are the advantages of using Design-Bid-Build?
The advantages include a clear project scope, competitive bidding that can lead to cost savings, defined roles and responsibilities, and better cost control through fixed-price contracts.
What are the potential challenges of Design-Bid-Build?
Challenges can include longer project timelines, potential for miscommunication between the designer and contractor, and the risk of disputes over design interpretations during construction.
How long does a typical Design-Bid-Build project take?
The duration varies based on project complexity, but generally, it can take longer than other methods due to the sequential nature of the design and construction phases.
What should clients expect during the bidding phase?
Clients can expect to receive multiple bids from contractors, which will include pricing and timelines. It's an opportunity to evaluate different contractors based on their qualifications and proposed costs.
How does Design-Bid-Build ensure cost control?
Cost control is achieved through fixed-price contracts with the selected contractor, based on detailed design documents. This minimizes unexpected expenses and helps keep the project within budget.
