Aileen is always eager to hop on another flight because there are so many interesting projects and people, and she gets tired of throwing her cats off her computer in her home office in Long Beach, California. “When you start with a blank sheet of paper, it makes people uncomfortable,” he said. But working through that discomfort can build trust and social engagement, he added.
ENR 2024 Top 500 Design Firms: Artificial Intelligence Ramps Up
Even during construction, visiting designers and contractors commented that the workmanship of plumbing, duct work, and electrical on the back of the modular cells looked like artwork. This helped to expedite the design process and developed several design options. As often happens in the traditional approach, we did not use the previous design to begin with or a computer-generated design option because these do not allow for team interaction. Instead, we began by using simple colored building blocks representing various building components. The team could move the blocks around and physically demonstrate to the team why a component should be located where it is.
Tips for Being Lean in Design-Build
Or, they could host a design competition to push design-build teams to produce more innovative solutions. The key here is flexibility – by moving beyond the lowest-cost-always-wins mindset, PDB allows owners to embrace a fuller, more meaningful definition of value. This results in better projects and better processes along the way to delivering a finished product.
Teaming Agreements, Collaboration Are Best for Design-Build
Progressive design-build refers to a project delivery method that uses a qualifications-based criteria, followed by a process where the owner negotiates a design and contract price directly with the construction team. That means the owner usually retains the design-builder early in the life of the project and, in some cases, before the design has been developed at all. PDB is an excellent option for complex projects with design and/or construction challenges, where the design-builder can provide very early input on design or constructability issues. Complex projects also benefit from high level, intense collaboration and teamwork. As complex projects are difficult to price, PDB’s collaborative, open book pricing allows the parties to make more realistic pricing assumptions with a better understanding of the risks involved. Despite these features, there are key contextual factors and contractual issues involved in proceeding with the PDB model.
The team supported the City with cost estimates, consideration of resiliency options, and the development of a conceptual cost-based alternative for use in determining the Progressive Design-Build team’s required qualifications and scope of work. The project team successfully reached a GMP at the 70% design completion level and obtained unanimous Board of Public Works approval. The new facility is anticipated to be fully operational in 2024—moving Los Angeles one step closer to a more self-reliant water future. The new Hyperion AWPF treatment process includes fine screens, membrane bioreactors (MBR), reverse osmosis (RO), ultraviolet irradiation-advanced oxidation (UV-AOP), and post-treatment stabilization.
The plan was then for the County to hire him, after construction was complete as the maintenance supervisor for the new facility. During construction, he saw every pipe that was run and every bolt that was installed. This creative approach provided the new maintenance supervisor with a thorough knowledge and understanding of the building systems and assured a smooth ongoing operation of the facility.
There is nothing worse than getting to bid day (I call it “surprise day”) and finding that you have multiple bids above your budget. Design-build gives the owner a high degree of control over the design and, in turn, budget. Where typically UDOT and its consultants would create a baseline and documents to give to the contractor, “now there is no arbitrary design” that “the contractor won’t use,” he said.
The budget for construction is negotiated during the design phase, typically when the designs are nearly complete. If the two parties can't agree on a price, the owner can terminate the relationship and explore other contracting options. One lesson the team learned involved clear lines of responsibility and timely decision-making. The PDB delivery method is a great vehicle to establish and maintain a team environment. With such a complex project, there are many decisions that need to be made throughout design and construction, and the timeliness of those decisions oftentimes has far-reaching impacts.

Based on research, case studies and extensive industry input, DBIA has defined design-build best practices and implementing techniques that deliver successful projects, no matter the size, type or sector. DBIA's Progressive Design-Build Primer introduces Owners and industry to the basics of Progressive Design-Build Done Right™. The goal of 5S is to ensure that equipment, information, and materials are provided to the proper people at the proper time, saving time for all members of the project team while also making the workplace safer. Once the design has reached a satisfactory point that meets the owner’s expectations, a formal commercial project proposal can be written. However, it contrasts with design-build (DB), where the owner’s team develops a baseline design. The MDTA finances, owns, operates, secures and improves Maryland’s toll tunnels, bridges and turnpikes.
This is because sub-contractors, as design-assist partners, are at the design table. My first-hand experience with other delivery methods is that contractors will look for opportunities for change orders due to the money they left on the table on bid day, but you do not have that environment with progressive design-build. Ironically, design-bid-build contractors challenge the sole accountability approach. They call it “the fox watching the hen house” since there are no separate architect and construction manager contracts. To counter this claim at Tipton County, Performance Services, as the design-builder, hired a new site superintendent specifically for the Tipton County Jail project.
I have learned throughout my career that constructing a building is truly a team effort. At Tipton County, we had a convenient meeting place for the team at the Tipton County Foundation Building and met weekly. Meeting face-to-face created an environment where everyone felt like they were part of a team they could trust. In another session at DBIA, contractors spoke candidly about what they would like to see in design-build jobs. “Standards of care and limits of liability are the biggest players,” said David Pupkiewicz, senior director of business development for Archer Western Construction, a division of Walsh Group. Owners should be more communicative regarding why they might shift risks onto the team, and design partners might take on more quantity risk.
The recycled water will also be used at HWRP to offset potable water in its wastewater treatment processes, as well as provide recycled water to existing internal infrastructure. One of the benefits of the progressive design-build model is that you can expedite parts of the project due to having ONE entity working for and making decisions with the owner. Starting from scratch, we designed the entire building and began construction in just four and a half months. Low tech was the most productive approach because there were no barriers to engaging in the brainstorming sessions. The design process established relationships that provided a lasting benefit which extended throughout the rest of the project. In addition to owner control, collaboration is the key to the progressive design-build process.
“Progressive design-build is new in transportation,” said Dave Nardon, director of alternative delivery for Superior Construction. “Just a couple of years ago, if you asked twenty people what progressive design-build is, you’d get thirty answers. For example, the District of Columbia Water and Sewer Authority’s board of directors approved a $819 million design-build contract in October for the construction of the Potomac River Tunnel, the largest ever awarded by the authority.
