Design-Build
A project delivery system in which a single entity performs both the design and construction of a project.
Design-build is a project delivery system used in the construction industry. It is a method to deliver a project in which the design and construction services are contracted by a single entity known as the design–builder or design–build contractor. It is used to minimize risks for the project owner and to reduce the delivery schedule by overlapping the design phase and construction phase of a project.
The main benefit of this system is that it gives the project owner a single point of contact for both the design and construction of a project.
- Type: Construction Framework
- Core Idea: Single Point of Responsibility
- Key Elements: Design-Builder, Overlapping Phases
Advantages of Design-Build
Why owners choose the design-build model.
Single Point of Responsibility
The owner has a single contract with the design-builder, who is responsible for both the design and construction of the project. This reduces the owner's administrative burden and eliminates disputes between the designer and the builder.
Faster Project Delivery
Because the design and construction phases can overlap, projects can be completed more quickly than with the traditional design-bid-build method.
Cost Savings
The design-builder has an incentive to keep costs down, and the owner can benefit from these savings. Also, because the project is completed more quickly, the owner can save money on financing costs.
Improved Quality
The design-builder is responsible for both the design and construction of the project, so there is a greater incentive to produce a high-quality product.
Reduced Risk
The owner's risk is reduced because the design-builder is responsible for any errors or omissions in the design or construction of the project.
Implementation & Strategy
Costs, timelines, and strategic considerations for adopting Design-Build.
Estimated Project Costs
Design-build is a project delivery system, so it doesn't have a direct cost. However, it can have a significant impact on the overall cost of a project. By overlapping the design and construction phases, design-build can reduce the overall project schedule, which can lead to significant cost savings.
Implementation Strategy
A typical design-build project starts with the owner selecting a design-builder. The design-builder is then responsible for both the design and construction of the project. The owner has a single point of contact for the entire project, which can simplify communication and decision-making.
