With Board approval of this contract, SFTC will as part of Phase 1 review existing design work, conduct constructability review, value engineering, bottoms-up cost estimate and schedule. During Phase I, SFTC will complete design validation, identify and negotiate early works packages, such as advanced utility relocations and final design, and develop the scope of work and price for Phase 2. Phase 1 will end if Metro and SFTC agree to a guaranteed maximum price and Metro will issue a supplement to the project contract to proceed to Phase 2, kicking off the construction portion of the project. Since the ConsensusDocs 415 is a lump sum agreement, the ConsensusDocs 400 is required to provide sufficient design detail to lock in a final fixed price, also known as a lump sum.
The Past, Present, and Future of Design-Build Construction
PDB has become more common in public-sector projects in recent years and has proven to help decrease project change orders, delays and cost overruns. PDB can also help reduce scope and schedule creep by addressing the highest risk elements much earlier in the process, well before construction begins. The first phase is a qualifications-based or limited-scope best-value selection to procure the design-build team before the price is set. If best-value is used in the selection process, fees, and compensation for the first phase can be considered.

The new 6.7-mile light rail is planned to include 11 new light rail stations along Van Nuys Boulevard and will improve connections to and access between Van Nuys and Pacoima. Several Equity Focus Communities, which are census tracts that have a significant concentration of underserved populations, are close to the planned rail line. Our integrated team of architects, engineers, and construction management professionals is ready to help with your next project.

Progressive Design Build a Hot Contracting Topic That's Gaining Attention
Despite its advantages, progressive design-build isn’t necessarily the right delivery method for every project. Owners or developers that have built similar projects in the past can typically draw on historical cost data for accurate budget forecasting. It is important to note that ownership of the designs at this point will depend on the original agreement – if the DB firm reserved rights to the design in the contract, the owner would need to rebid the entire project, including the design development. To help create a new, sustainable water supply for Los Angeles and maximize water reuse at HWRP, the Walsh/Brown and Caldwell (BC) design-build team is working with LASAN to construct a 1.5 mgd Hyperion AWPF.
Progressive Design-Build Team
If the owner accepts their proposal, they will either sign an extension to the original contract or create a separate contract for the construction services. The two-phase, fixed-price contract will include design, right-of-way acquisition, utility relocations, construction services, and construction management services. There will be multiple standalone construction projects and therefore multiple GMPs. Since the founding of the Design-Build Institute of America (DBIA), design-build has gone from a new, alternative project delivery method, to a standard option owners regularly turn to for best value in project delivery. So while DBIA will continue to promote the use of design-build where it is limited or unauthorized, more experienced owners are perfecting the design-build method itself. Over the past several years, the water/wastewater sector has been doing just that by steadily adopting Progressive Design-Build, and now the transportation sector is starting to do the same.
Progressive Design-Build Done Right™ Schedule
PDB represents a departure from traditional construction methods, offering a dynamic and collaborative framework that promotes innovation and flexibility throughout the project lifecycle. The PDB model features a collaborative approach between the owner and its contracting partner during the early stages of projects such as project requirements and design work. It introduces additional steps that enable the owner and design-builder to progressively develop a design solution before jumping directly into detailed design and construction.
Many of her experiences with engineers and contractors have inspired material for her alternative theater productions way, way off Broadway. For ENR, Aileen has traveled the world, clambering over bridges in China, touring an airport in Abu Dhabi and descending into dark subway tunnels in New York City. She is a regular at transportation conferences, where she finds that airport and mass transit engineers really know how to have fun.
One Contract – You Know Who to Hold Accountable Throughout the Life of the Project
Instead, the contracting team is involved in the scoping and design, and an independent cost estimator is used to reconcile any differences. The method is best for “schedule-driven, complex, phased construction,” he noted. Most are familiar with Design-Build, whereby the design and construction services are contracted to a single entity known as the design-builder. The design-builder is responsible for all work on the project, often providing a turnkey solution for the owner. Although the use of subcontractors to complete more specialized work is common, the design-builder remains the primary contact and primary force behind the work. At its core, PDB is a delivery method that allows for collaborative development project criteria that is a qualifications-based procurement process versus one based primarily on cost.
This included elevating the RO feed tank from below grade to above grade and reducing product water tank volume.2. Expediting preparation of a revised draft Basis of Design Report to reflect the new project vision, which was subsequently approved.3. Conducting a manufacturer preselection process for MBR and UV-AOP vendors to streamline design and cost model development.4. Selecting equipment early at the 30% design level, which allowed the design to progress for each area in parallel with selection.
In some cases, the owner was very specific about what they wanted to ensure a quality outcome. For example, they chose a known vendor for good reasons, such as ongoing service and reduced maintenance. The owner got to choose between various manufacturers to select what they felt was in their best interest. Because of progressive design-build, the owner got a higher level of security, more classifications, and a mental health unit all within the budget.
The communication and working relationship with Performance Services has been excellent. I’m confident that we have a design that meets all our program needs, is innovative, highly efficient, within our budget, and will reduce ongoing operating costs. Labor unions often scrutinize legislation for any potential impact on their workforce.
PDB also uses primarily a qualifications-based selection, followed by a process whereby the Owner then “progresses” toward a design and contract price with the team (thus the term “Progressive”). When operating under traditional project delivery models such as Design-Bid-Build, the owner holds separate contracts with the design team and the construction team. The lack of contract-forced communication between the design and build teams forces the owner to serve as an in-between and also leads to rework as the two teams fail to properly coordinate their efforts.
On the other hand, PDB is focused on a qualifications-based procurement process. This approach allows the owner to select the design-build contractor prior to developing a baseline design, saving time and money. In a PDB project, the owner issues a Request for Qualifications, and selects the design-build contractor based on the contractor’s qualifications and past performance.
