The Design-Build Construction Method: Advantages and Drawbacks

design and build

The Design-Build selection process, conversely, puts in place a rigorous competition procedure that focuses on qualifications, experience, technical approach, price and other factors. This encourages a better competition that allows many qualified firms of all sizes to participate. In a traditional design-bid-build model, the owner bears significant risk and may lose money if, for example, an approved design has to be changed once construction has begun. The design-build model takes much of the risk off a project owner and puts it on the design-build team.

Types of Design and Build Contracts

The project usually progresses as an integrated process, overlapping the two phases. This speeds everything up, and a single leader—the design-builder—is responsible for meeting the contract requirements. The design-builder is also responsible for spotting inconsistencies between prescriptive requirements and performance standards and reporting those to the owner and other stakeholders. Once owner and project team have defined the big picture, preliminary drawings progress into detailed design and schematics. And the project team works in fluid collaboration to produce cost estimates at 30%, 60% and 90% design completion. At the conclusion of this process, owners receive a guaranteed maximum price (GMP), a set project schedule and contract drawings — the drawings used to build a facility.

Design-Build Contract

During construction, the owner will remain in close contact with the contractor. The contractor will create a change order for any design changes needed during construction. An owner who receives a change order may consult with the design team, go over any costs involved in the change, and approve the change. The Design-Bid-Build (DBB) Construction Delivery Method is considered the traditional organizational structure for construction builds. It has remained popular because it's simple, and owners often feel it can help maintain lower project costs than other methods.

Better Communication

These days, nearly half of all the nation’s projects are delivered using the design-build delivery method. The model promotes greater collaboration between design and construction teams, offering greater efficiency and cost savings. Continued growth and innovation in construction technology, including construction management software and BIM, will further emphasize the benefits of the design-build model. As construction projects become more complex and the demands of the construction industry grow, construction owners increasingly rely on design-build to leverage industry expertise to deliver projects successfully.

To further explore the topic of construction costs and how to plan for them, see our guide to construction finance. Delivering a successful Design-Build project requires open collaboration between all team members. Creating a team-oriented approach promotes high levels of communication and transparency, both imperative to the success of any project. It allows owners to share their vision with the team, and align the interests of the stakeholders. The team-oriented approach also provides the collaborative effort necessary to evaluate the project’s objectives, assess schedules and analyze opportunities as the project progresses.

Role of a Contractor in a Design-Build Contract

Construction contracts, especially for large projects, can be extremely detailed with many key documents often compiling thousands of pages. By comparison, the design-build method puts the contracting and design specialists on the same team alongside the owner. Information sharing the cooperation becomes the default, so recommendations to the owner are unified and based on the owner's specs and budget. By this point, the owner can develop a draft request for proposal (RFP) and provide it to selected proposers, who can ask questions and make qualifications before bidding and before the owner finalizes an RFP. The owner will seek out proposers who offer value in delivering project goals rather than selecting the lowest price. When this partnership works, it can diminish the number of costly and time-consuming change orders and result in a better project.

Whether or not design-build is the construction method of choice, as contractors move toward more digitized, mobile operations, the cloud is serving as the vehicle for modern construction management. With construction-specific, connected solutions operating in the cloud, contractors can streamline their operations and work data in real time instead of days, weeks or even months later. This helps boost project productivity, and save costs and increase profitability dramatically.

What is Design-Build Construction?

They provide the basis for the contractor’s proposal, design, and construction process, ensuring the project aligns with the owner’s vision, expectations, and objectives. With a D&B contract, the project owner hires a single company to perform design and construction under one contract, reducing administrative and management responsibilities [7]. DBIA is committed to help connect Owners and industry looking for qualified team members. Our one-of-a-kind Industry Match tool allows users to search an online directory of qualified design-build firms by region, market, specialties, Underutilized Business Enterprise (UBE) status, project type and more.

However, the design-build firm is there to guide them and act on their behalf, taking on a substantial amount of the project’s burden and risk that would typically fall to the owner in other project delivery methods. They’re there to support you and make the process easier – not dictate what you can and cannot do. Design-Build is a project delivery method that merges the designer and builder so that the two are part of the same organization that handles the entire process. Through the years, the construction industry has gravitated toward alternative project delivery methods like CMAR and integrated project delivery. It is known to save money and make otherwise impossible timeframes more realistic and achievable, making it an easier sell to project owners. The design-bid-build project delivery method is often compared and contrasted with design-build.

But because the project rests on a solid plan from the beginning, the team will have more bandwidth to deal with challenges as they occur. The University of Washington constructed this 300,000 square foot facility in three years, coming in 2.5 percent under the grant budget for a savings of $4.5 million. University of California, Irvine residential project delivered a fast-track multiple package project with over 80 value items beyond the RFP.

The design-builder must foster professional relationships that will help move the project forward. If new to the delivery method, the design-builder should commit to the organizational structure and software that will work for the team to complete the project successfully. Regardless of the project delivery method used, clear, consistent organization and accessibility of project information and open communication can help foster understanding and overall project success. A design-build team that does not work together effectively can result in considerable difficulty for a contractor who is left with an unbuildable design and yet bears the responsibility for producing a quality finished project.

A reliable design build firm displays expertise, excellent communication skills, acute attention to detail, and utmost professionalism. Construction manager at risk (CMAR) is a method of project delivery in which the owner contracts a construction manager to take on a construction project during its design phase, and... That open communication and additional pre-planning also manifests in faster project completion. Unlike design-bid-build, which requires time dedicated to the bidding process, design-build moves straight from the single-contract design phase to the construction phase. With everyone on a single team, the project can move forward quickly without many of the usual snags related to paperwork and contracts. Construction can begin once the GMP is agreed upon and the design is finalized.

The owner and designer will determine a project's structure and features, the scope of the project the owner will bid and the primary criteria that define a successful outcome. Architects can be employed directly by the Design-Builder, or the Design-Builder can subcontract out specialty design to trusted architectural design partners. Architects work on the same team, under the same contract, with the Design-Builder. And all key project team members come together to form a design that balances all needs.

Post a project today on ContractsCounsel and receive bids from construction lawyers who specialize in design-build contracts. If it does, it’s the responsibility of the design-builder to pay—not the owner. The owner typically has one main point of contact who then enters into contracts with the architect, engineers, and other partners on the owner’s behalf. If you want to know how this popular construction approach is different from the traditional methods, you’ve come to the right place. In this blog, we’ll take a look at what makes a design-build project, what the team structure looks like, and what steps are involved.

The result should be a cheaper and prettier building and a happier team overall. In traditional Design-Bid-Build projects, the client separately hires the contractor and architect and the two must cooperate, or fight, to get their jobs done. The architect usually starts their job first and will design the building, eventually producing a bid set of drawings. Builders then bid on the project based off of the drawings, and the winners take over and must adapt the architect’s drawings to the realities of the site and build the building. We created this guide to lay out everything you need to know about design-build, including the steps in the process and the benefits it provides over traditional construction. We also cover choosing the right design-build firm and the future of design-build in the construction industry.
