Design Build Contract Vs Traditional Construction

Design-Build and Traditional Construction are two different project delivery methods in the construction industry, each with its own advantages and disadvantages.

Design-Build Construction is a project delivery method that involves a single contract between the owner and the builder. Unlike traditional construction contracts, which require two separate entities: a designer and a contractor, a Design-Build contract combines these two entities. Only one company is responsible for the design and building contract for a project, removing the bidding stage. This method is known to save money and make otherwise impossible timeframes more realistic and achievable.

It streamlines communication between the contractor, subcontractors, and owner and fosters a team-oriented mindset. It also encourages innovation and creative problem-solving. Some of the main benefits of choosing this process over a general contractor include simplifying designing, planning, and building processes through a single point of contact, unified project recommendations, collaborative problem-solving, no blame-shifting between designer and contractor, and one point of responsibility.

Traditional Construction, on the other hand, is a more linear and time-tested process. It involves separate contracts for the design and construction phases of a project. The design phase is completed first, and then contractors bid on the project based on the completed design. This method allows for more control in the design phase and offers the opportunity to work with multiple specialized contractors.

Traditional construction is reliable and hard-wearing, with buildings able to survive for many years in harsh environments with limited maintenance required. They can be constructed in a wide range of shapes and sizes. However, one significant disadvantage is the potential for cost overruns, which can adversely impact project budgets. Traditional construction can also take longer than design-build due to its linear nature, with steps typically completed one after the other.

Table of comparison:

Feature Design-Build Contract Traditional Construction
Project Delivery Single contract between owner and builder. Separate contracts for design and construction phases.
Entities Involved One entity responsible for design and construction. Separate entities for design (architect) and construction (contractor).
Bidding Process No separate bidding process; streamlined. Bidding process for construction after design completion.
Responsibility Single point of responsibility for design and build. Design and construction responsibilities are distinct.
Communication Streamlined communication between parties. Communication may involve multiple entities, potentially leading to delays or miscommunication.
Timeline Can save time with simultaneous design and build. Linear process may take longer due to sequential phases.
Flexibility Greater flexibility for changes during construction. Changes may be more challenging and costly to implement after the design phase.
Innovation Encourages innovation and creative problem-solving. Limited innovation during construction due to pre-determined design.
Cost Control Potential for better cost control with fewer change orders. Potential for cost overruns, especially if changes are needed after the design phase.
Quality Control Continuous collaboration can enhance quality control. Quality control is typically more segmented, with design and construction phases distinct.
Risk Distribution Shared risk between design and construction phases. Risk may be more concentrated in the construction phase.
Client Involvement More involvement and collaboration with the client. Client involvement primarily in the design phase; less during construction.
Adaptability to Changes More adaptable to changes during construction. Changes may be more challenging and costly to implement after the design phase.
Suitability for Complex Projects Well-suited for complex projects with tight schedules. May be suitable for straightforward projects with less time sensitivity.
Examples Fast-track construction projects, renovations. Traditional buildings, infrastructure projects.

Key Takeaways:

  • The design build contract approach combines both design and construction under a single contract, providing single-point accountability.
  • Design build projects have shown to have lower costs, faster completion times, and fewer change orders compared to traditional construction.
  • Traditional construction, also known as Design-Bid-Build, involves separate contracts for design and construction, potentially leading to slower project delivery and increased risks.
  • Design build offers streamlined communication, collaboration, and value engineering opportunities, resulting in optimized costs and better budget control.
  • Traditional construction may have limited owner control during the design phase, potential conflicts of interest, and limited competitive bidding.

Advantages of Design Build Contract

The design-build approach offers numerous advantages for construction projects. Working with a design-build firm provides the benefits of single-point accountability, where the same entity is responsible for both the design and construction phases of the project. This streamlined approach ensures smoother communication and collaboration among the project team, leading to faster project completion.

Reduced risk is another advantage of the design-build approach. With a single contract, the project owner has less risk compared to traditional construction, where separate contractors handle design and construction. The design-build firm takes on the responsibility for delivering the project within the specified budget and timeline, reducing the owner’s potential risks.

Value engineering for optimized costs is a key benefit of the design-build approach. Design-build firms have the expertise to identify cost-saving opportunities throughout the project and suggest alternatives that maintain the project’s quality while optimizing costs. This value engineering process ensures that the project stays within budget without compromising on important features or functionality.

The streamlined communication and collaboration in design-build projects also contribute to faster project delivery. By having all stakeholders involved from the beginning, potential delays or miscommunications are minimized. The design-build team can work together seamlessly, making quick decisions and resolving issues promptly, resulting in faster project completion and delivery.

Overall, the design-build approach offers significant advantages, including single-point accountability, faster project completion, reduced risk, value engineering for optimized costs, and streamlined communication and collaboration. These benefits make the design-build contract a compelling choice for construction projects, ensuring efficient and successful project delivery.

Drawbacks of Traditional Construction

When it comes to traditional construction, there are a few drawbacks that should be considered. One of the main disadvantages is the limited control that the owner has during the design phase. Unlike with the design-build approach, where the owner is involved in the decision-making process from start to finish, traditional construction often leaves the owner with little direct input into the design decisions.

This limited owner control can lead to potential disconnects between the project vision and the final outcome. Without the ability to provide direct feedback or make adjustments during the design phase, the owner may find themselves dissatisfied with certain aspects of the project.

Another drawback of traditional construction is the potential for conflicts of interest. Since separate entities handle the design and construction, there may be competing priorities and cost-cutting decisions that can impact the overall quality of the design and construction process.

Furthermore, traditional construction may have limited competitive bidding compared to the design-build approach. With design-build, there is only one entity responsible for both the design and construction, allowing for a streamlined bidding process. In traditional construction, multiple contractors are involved, which can limit the opportunity for price comparison and negotiation.
