The contractor submits the required changes along with a quote for the additional costs that will result, and the owner signs off on the changes. The Washington Department of Transportation (WSDOT) used the DBB project delivery method to improve a bridge at the Wenatchee River crossing. The bridge was originally constructed to have one westbound and two eastbound lanes. The project team widened the bridge to allow for five lanes, plus room for a median and shoulders on either side. The Design-Bid-Build (DBB) Construction Delivery Method is considered the traditional organizational structure for construction builds.
Your Capital Project, Your Way
Selecting the best delivery method for the project can help reduce overall risk and bring the project in on schedule and on budget. In the design build approach, the responsibility for both design and construction rests with a single entity, typically a construction firm or a team consisting of architects, engineers, and contractors working together. This integrated approach promotes collaboration from the project’s inception, leading to streamlined communication, enhanced coordination, and faster project delivery. By consolidating design and construction under one roof, potential conflicts are mitigated, leading to smoother project execution and reduced turnaround times. Additionally, the close collaboration between designers and builders fosters innovative solutions and value engineering, ultimately resulting in more cost savings for the client.

Project delivery methods dictate the roles and responsibilities of project stakeholders throughout the design and construction of a new build. Which method owners choose depends on many factors, including the owner’s skillset and comfort level with the building process, and the specifics of the project at hand. The design-bid-build delivery method is the traditional standard for construction projects and historically the most popular method. For one, the owner contracts with both an architect/engineer for the project’s design and a contractor to construct the project. Both design-build and design-bid-build have unique strengths and weaknesses, making them suitable for different projects.

Today she focuses most of her efforts on unlocking the challenges of the subsurface, through research and education. The figure below shows the legal status of Design Build contracts by state as of 2019. A skilled Design-Builder will convey only the proper amount of information to their audience without overwhelming them. A good Design-Builder is also trusted to make judgments on behalf of the client that will boost the project’s overall value.
Pros & Cons of Design-Build Delivery Method
However, because the contractor’s offer reflects just that narrow scope, creating a finite scope of work can be a drawback. During the bidding process, any unforeseen costs or design flaws can expose the developer. Additional design work to resolve these vulnerabilities can and will detract from a project’s success. To eliminate the stigmas mentioned in the cons section above, a design-build delivery demands a high level of trust and knowledge from all sides.

The way that these phases are organized and overlap—and the different stakeholders involved in each phase—is the key difference between different types of project delivery methods. The different structures of a delivery method can have big implications for subsurface utility strategy. 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. While they may appear to only have one word of difference, the process and planning involved with each method varies tremendously.

In this article, we’ll review the differences between these two contract types and outline how e-bidding software is being used for design-build proposal evaluation. The general contractor in charge of construction by the DB method is involved right from the beginning. The contractor can lend expertise and experience to the design process that could contribute to fewer problems during construction, and even a more efficient and cost-effective build overall. The contract will often set out a guaranteed maximum price (GMP) for the owner, which takes much of the risk from the owner and places it onto the construction manager. With the contractor not involved in the design process, issues that could have been addressed earlier often will come to light later.
Once the design phase is complete, the owner can issue this to general contractors to begin bidding. The owner will receive quotes from numerous contractors looking for the lowest price. The project owner will be locked into a guaranteed maximum-price contract with the construction company to complete a defined scope of work. This method offers collaboration between designers and builders, creating a solid alignment of project goals and objectives. E-Bidding platforms like our own Bid Express have begun to incorporate scoring and evaluation features to make them flexible enough to use for both design-build and unit price contracts.
The Benefits of DBB
The Michelle and Barack Obama Sports Complex (formerly called the Rancho Cienega Sportsplex) in Los Angeles was delivered by design team Studio Pali Fekete Architects and general contractor Pinner Construction in 2022. It's a 49,000-square-foot sports facility that was built to replace the existing center. On long, involved projects, the opportunity for concurrent building and design can save months or years off a project's schedule. The contractor executes the build, overseeing day-to-day site activities and hiring and overseeing subcontractors.
In this post, we’ll take a deep dive into the two most common project delivery methods— Design Bid Build (DBB) and Design Build— and look at their relationship with utilities and utility strategy. Delivery methods determine the roles and responsibilities of the project stakeholders during the different phases of construction. In design-bid-build, construction progresses in three distinct phases that follow one another, just as the name suggests. In this article, we’ll take a look at how design-bid-build compares to the other emerging construction project delivery methods, and how owners can help determine which project delivery method is best for them. The defining characteristic of the Design-Build project delivery method is the early collaboration between design team and general contractor.
This only raises the importance for design builders of tackling utility challenges from the outset. The procurement phase involves advertising, accepting/evaluating bids, tender offers, or proposals depending on project delivery method, and awarding the final construction contract. During the procurement phase, understanding the utility landscape is crucial, as it influences the complexity, price, risk, and contingency of the bids. In this article, we’ll discuss two—Design Bid Build and Design Build—but there are other methods (like GCAR and PPP) that are also increasingly common. Design-Bid-Build is best for linear project sequences where one step is completed before the next is set to begin.
The owner can also compare different bids from different contractors, and choose the one that offers the best value and quality. Another benefit of DBB is that it is more transparent and accountable, as the roles and responsibilities of each party are clearly defined and separated. The owner can monitor the performance of the designer and the contractor, and hold them liable for any errors or defects. If you are a construction supervisor, you need to understand the different procurement methods and models that can affect your project's success. One of the most common choices you have to make is between design-bid-build (DBB) and design-build (DB). These are two ways of delivering a construction project, with different roles and responsibilities for the owner, the designer, and the contractor.
The design-builder may also face more challenges and uncertainties in managing the design and construction teams, and in coordinating with the owner and other stakeholders. When it comes to design build vs design bid build, let the project specifics be your guide to selecting the most appropriate delivery method. There are two primary project delivery methods, design-build and design-bid-build.
Finally, since owners are free to work with multiple providers, each vendor is incentivized to deliver top-notch service, fostering innovation and continuous improvement. Once the winning bid has been selected, the build phase begins, and the general contractor’s team can get to work constructing the new facility. A unique feature of the Design-Bid-Build method is that the designer will oversee the work of the general contractor and subcontractors. However, it is important to understand that both approaches can be highly successful with proper pre-project planning, scope definition, and execution strategy. At Hammers Construction, we understand the importance of choosing the right approach for your construction project, and we’re here to help you make the right choice. Whether you’re embarking on a commercial, industrial, or institutional project, trust Hammers Construction to be your partner every step of the way.
