The design-build project delivery method offers many advantages to owners in various building scenarios, but like all building projects, design-build carries some risk. Because of the breadth of a design-build contract, one of the most significant decisions the owner needs to make is selecting a design-build team. You may find design-build more appealing because you will only have one contract and be dealing with one entity. On the other hand, you may find design-bid-build more appealing because you want the flexibility of choosing the architect to provide the design services and then choosing a separate contractor to perform the construction. You may also want the assistance of the architect to provide the construction phase services rather than doing it yourself.
What is a project delivery method?
During this process, the builder and designer work hand-in-hand to provide design, engineering, and implementation services. The early and frequent collaboration between architects, engineers, estimators, trades, and construction disciplines defines this method. Owner preferences and abilities, locales, and project times may impact the top priorities for the project delivery teams that work on them. The emergence of new project delivery methods makes it easier for each team to devise an organizational plan that works for each project. While there are plenty of project delivery methods available to use, two at the top of nearly any list are design-bid-build and design-build.

New developments may warrant the need for design changes or clarifications. The architect also reviews the progress of the project to certify that the contractor follows the design. Construction projects often involve a sole owner that’s in charge of everything from finances to project progress to design, and use a sole prime contract for all the building work.... On long, involved projects, the opportunity for concurrent building and design can save months or years off a project's schedule.
Preliminary Design and Cost Estimation
This method can lead to slower project delivery and potential cost overruns. In fact, construction could halt if the design isn’t complete or last-minute changes are made. This separation allows the owner to influence the design process significantly. However, it might also lead to extended project timelines as the bidding process and the construction only start after the completion of the design. The main difference lies in how the design and construction phases are handled. With design-build, a single entity is responsible for both phases, while in design-bid-build, separate entities handle these phases.

Once construction is complete, the design-build team reviews the project with the owner for final acceptance then hands the project over to the owner. Architects have a professional responsibility to create a design on behalf of the owner. Since there's no agenda on the build-out, it will likely provide the highest-quality and most objective set of drawings.

Sometimes, but not always, projects that are simpler, more predictable, and smaller scale will take place under Design-Bid-Build methods. The majority of public sector projects are still built using Design-Bid Build methods, as are many private sector projects.

This leads to misunderstandings, poor cost and schedule management, and, in some cases, significant project delays. Increased collaboration from the earliest stages of project development can lead to significant budget savings and more efficient schedule creation. The main thing that makes the design-build project delivery model stand out is its emphasis on collaboration, which can impact anything from the project bids and scheduling to the quality of the finished product. The design-build method is most often understood by comparing it with the more traditional design-bid-build method, which involves an owner entering into two main contracts.
Cost Efficiency in Focus: Design-Build vs. Design-Bid-Build Delivery Method
Today she focuses most of her efforts on unlocking the challenges of the subsurface, through research and education. This aspect can significantly reduce the time it takes to deliver a finished product, especially for large, extended-time projects. You will get the most competitive pricing since contractors are competing to win the job. The architect then uses this information to develop a conceptual or schematic design.

A Clear Distinction Between Teams
Therefore, it's crucial to thoroughly evaluate the nature and requirements of your project before choosing a method. At BB&R Design-Build, we offer expertise in both processes, ensuring your project's successful and efficient completion. Whether you prioritize speed, cost-effectiveness, or design control, we can provide your unique needs and help you realize your vision. Both design-build and design-bid-build have unique strengths and weaknesses, making them suitable for different projects. Design-build is often preferred for fast-track projects with tight timelines and complex designs.
The short-listed bidders are issued a request for proposals (RFP) which requires them to submit a technical design proposal and a corresponding price proposal. When elements of the design reach a point where they are complete, the owner has the option to commence the construction phase before completing the final design. The success of a design-build project may hinge on the level of trust and collaboration within the design-build team. When project teams sign on to separate contracts, they get to focus on their realm of expertise. Designers don't have contractors in their ears when they design, and contractors can focus on building without worrying about overseeing designs.
Under a design-build contract, the owner hires one company to oversee the design and construction of the new property, also known as a single-entity construction project. Design-build is frequently used for residential and large-scale commercial projects like hospitals, office buildings, and large infrastructure. Design-build combines the roles of designer and contractor into a single entity, while design-bid-build keeps them separate. This distinction influences delivery, cost, quality, and other aspects of the construction process.
Here's how design-build compares to other common project delivery methods. If you are using the design-build delivery method, you will only hire one entity, the design-builder, rather than a separate architect and contractor. Design-builders are often contractors, and many residential home builders are design-builders. Some design-builders offer complete design services, using an in-house architect or by contract with a third-party architect. In other instances, a design-builder or home builder in residential construction may have pre-developed plans and the homeowner can select which plans they would like to use, which simplifies the process. There are other delivery methods used in construction (such as construction management or integrated project delivery), but those are generally used for more complex projects.
Every construction project and the circumstances surrounding it is different. Selecting the best delivery method for the project can help reduce overall risk and bring the project in on schedule and on budget. The design-bid-build project delivery method is a more multitiered approach than design-build. First, a design team works with the project owner to prepare the programming, design the project, and draft the contract.
The Colorado STA recommend that even in design-build projects, project owners should conduct their own utility investigations. Further, stakeholders should make sure agreements with private utilities are already set before procurement—as design builders have a tough time pricing these risks beforehand. Some of the design and construction risk for public utilities can be passed on to the design builder—so long as it is clearly spelled out in the contract terms.
