What is Design-Build in Construction?

In construction, what is design build in construction stands out as a streamlined, efficient project delivery method that integrates both design and construction services under a single contract. This approach contrasts sharply with traditional methods, which typically involve separate contracts and entities for design and construction. Let’s break down the key components of design-build:

Single Contract

The cornerstone of the design-build method is the single contract. Instead of juggling multiple contracts and points of contact, the project owner signs just one contract that covers all aspects of both design and construction. This simplifies the entire process, from communication to billing, making it easier for owners to manage their project.

Unified Team

A unified team is another fundamental aspect of design-build. This team typically includes architects, engineers, and construction professionals who work together from the start of the project. This unity promotes seamless communication and collaboration, enabling the team to solve problems quickly and efficiently, often leading to innovative solutions that might not be possible in a more segmented approach.


In design-build, the design/construct phase is not a sequential process but a simultaneous and collaborative effort. From the initial concept to the final construction, every step is aligned and integrated. This approach not only speeds up the project timeline but also enhances the quality of the final product, as the design and construction teams can immediately apply feedback and make adjustments in real-time.

By understanding these key elements of design-build, it becomes clear why this method is gaining popularity. It offers a cohesive, efficient alternative to traditional construction methods, providing benefits like faster project completion, cost savings, and improved quality. We’ll compare design-build to other methods and delve into the specific phases of the design-build process, highlighting how each contributes to the overall success of a project.

Key Advantages of Design-Build

Faster Delivery

Design-build speeds up the entire construction process. How? By merging design and construction phases, there’s no need to wait for one phase to complete before starting the next. This overlap means that while the design is being finalized, site preparation can begin, saving valuable time. Studies have shown that design-build projects are delivered 33.5% faster than those using traditional methods like design-bid-build.

Cost Savings

One of the most significant advantages of what is design build in construction is the cost efficiency it brings to the table. With a single team handling both design and construction, there are fewer parties to coordinate, leading to lower administrative costs. Moreover, this setup minimizes the risk of miscommunication, often a costly affair in traditional setups. The fixed price contract, commonly used in design-build projects, also means that the budget is agreed upon upfront, reducing the likelihood of unexpected cost overruns.

Better Quality

When the same team designs and builds the project, there’s a unified commitment to quality. This integration often results in innovation and custom solutions that meet or exceed the owner’s expectations. The design-build approach allows for more flexibility to adapt the design during construction without significant delays or cost increases, ensuring the final product is of the highest quality.

Singular Responsibility

With design-build, one entity is responsible for both the design and construction of the project. This means there’s a single point of accountability, which simplifies the resolution of any issues that may arise. Owners benefit as they don’t have to deal with multiple contracts and the potential disputes between designers and builders. This single-source responsibility leads to fewer legal battles and a smoother project flow from start to finish.

By consolidating the roles of designer and builder, design-build not only enhances the efficiency of the construction process but also improves the overall project experience for the owner. As we explore further, we’ll see how design-build compares to other construction methods and detail the specific phases of the design-build process, illustrating its effectiveness and efficiency at each step.

Design-Build vs. Traditional Methods

When considering construction project delivery methods, compare design-build with traditional approaches like design-bid-build and construction management. Understanding these differences can help you decide which method best fits your project needs.


This is the most traditional project delivery method in construction. Here’s how it works:

  1. Design Phase: You hire an architect or designer to create detailed plans.
  2. Bid Phase: Contractors bid on the project based solely on the designs.
  3. Build Phase: The winning contractor builds the project.

This method often leads to:
– Longer project timelines due to sequential steps.
– Increased potential for disputes as multiple parties try to shift blame for issues.
– Possibly lower initial costs, but changes can become expensive.

Construction Management

Construction management involves a construction manager acting as an advisor to the owner through both the design and construction phases. This approach can offer:

  • Guidance and Oversight: The construction manager provides expertise without taking full control.
  • Flexibility: More control over the design and construction phases.
  • Cost Management: They help keep the project within budget by advising on cost-saving measures.

However, this method can still involve multiple contracts and the potential for conflicts between different teams.

Sequential vs. Integrated Approach

The key difference between traditional methods and design-build lies in their structure:

  • Sequential: Traditional methods like design-bid-build involve clear, separate phases. Each phase must be completed before the next begins, which can slow down the process.
  • Integrated: Design-build integrates all aspects of a construction project under one contract. This approach fosters collaboration and speeds up the entire process.

Design-build streamlines project delivery by combining design and construction services under one roof. This integration not only speeds up the construction process but also reduces misunderstandings and conflicts. Here’s why:

  • Single Point of Responsibility: One team is accountable for every aspect of the project, from initial design through final construction. This minimizes the blame-shifting that can occur in traditional setups.
  • Enhanced Communication: With a unified team, communication is more straightforward, ensuring that any issues are quickly addressed without delays.
  • Cost and Time Efficiency: Early collaboration in design-build allows for more accurate cost estimates and timelines. Changes can be managed more effectively without the need to renegotiate contracts.

In conclusion, while traditional methods have their place in certain types of projects, design-build offers a compelling alternative that can lead to faster, more cost-effective builds with fewer complications. We’ll delve into the specific steps of the design-build process to further highlight how this method enhances project delivery.

The Design-Build Process Explained

Site Selection and Project Conception

The initial step in the design-build process involves site selection and project conception. This phase is crucial as it sets the foundation for the entire project.

  • BIM and VDC: Building Information Modeling (BIM) and Virtual Design and Construction (VDC) are used extensively during this phase. These technologies allow for 3D modeling of the project, providing a visual and functional preview of the building, which enhances decision-making and reduces the likelihood of errors.
  • Preliminary Designs: Initial designs are crafted during this phase. These designs are refined continuously through feedback from all stakeholders, ensuring that the final design meets the owner’s expectations and functional needs.

Construction Phase

With designs in place, the project moves into the construction phase. This stage is characterized by efficient management and communication practices.

  • Subcontracting: The design-build firm manages all aspects of subcontracting. With a single entity coordinating the project, there’s less chance for miscommunication and delays that often occur in traditional methods.
  • Daily Management: Effective daily management is pivotal. The project manager coordinates with the team, ensuring that the project stays on track and adheres to the budget.
  • Streamlined Communication: Having a single point of contact simplifies communication. All queries and updates flow through this channel, making the process smoother and more integrated.

Project Closeout

The final phase of the design-build process is project closeout, which involves several critical activities to ensure the project is completed to satisfaction.

  • Documentation: Comprehensive documentation is prepared and delivered to the owner. This includes detailed drawings, user manuals, and maintenance guides.
  • Post-construction Review: A thorough review of the project is conducted to evaluate its success and learn from any challenges encountered. This feedback is vital for continuous improvement in future projects.

In this streamlined process, each phase transitions smoothly into the next, with a focus on efficiency and collaboration. This method not only saves time and money but also reduces stress for the owner, providing a clear path from concept to completion. As we explore common concerns with the design-build approach, we’ll address how to select a design-builder, ensure owner control, mitigate risks, and maintain transparency throughout the project.

Frequently Asked Questions about Design-Build

What is the difference between design-build and build only?

In construction, these two methods serve different purposes and involve distinct processes:

  • Design-Build: This is a unified method where one entity, the design-builder, manages both the design and construction phases of a project. This approach fosters collaboration as the architect, engineers, and contractor work together from the start, creating a more streamlined and efficient process. The key advantage here is that any changes in design are handled by the same team that manages construction, leading to fewer misunderstandings and delays.
  • Build Only: Here, the construction company is only tasked with building according to pre-existing plans created by architects and engineers hired separately by the owner. This method can lead to challenges in communication and integration as the builders may not be involved in the design phase and thus may encounter issues that were not anticipated by the designers.

How does design-build promote better quality in construction projects?

Design-build promotes better quality through:

  • Integrated Team: Having a single team from start to finish enhances accountability and aligns the interests of designers and builders, leading to higher quality outcomes.
  • Collaboration: Continuous communication throughout the project reduces errors and allows for real-time problem solving and innovation.
  • Owner Involvement: Although the design-build team handles the details, the owner remains closely involved, making decisions alongside the team, which can lead to a better final product that truly meets their needs.

What are the potential downsides of the design-build approach?

While design-build has many advantages, there are a few potential downsides:

  • Less Competitive Pricing: Since there is only one bid for both design and construction, owners might miss out on potentially lower bids for each phase that could be obtained separately under the design-bid-build method.
  • Limited Design Options: The design-build process might limit design innovation as the focus may lean more towards efficiency and cost-saving. This can sometimes result in designs that are less creative or bespoke.
  • Conflicts of Interest: Since the contractor and designer are part of the same team, there might be a perceived conflict of interest, where design decisions could favor the construction methods or materials that are more profitable for the contractor rather than what is best for the project.

Understanding these aspects helps in making an informed decision when choosing the right project delivery method for your construction needs. With careful planning and clear communication, the design-build approach can significantly enhance the quality and efficiency of construction projects.
