Design-Build Taking Hold

The use of design-build as the delivery method for construction projects has been increasing at a steady pace since the early 90s due to its many benefits, including a single source of accountability for quality, cost and timeliness, economical efficiency, open communications, faster project completion, quality enhancement, reduced administrative burden on the owner and early knowledge of construction costs.

When the Design-Build Institute of America (DBIA) was formed in 1993, nonresidential design-build projects made up about 15% of the market, and they now make up about 40% of the market.

“The whole AEC industry is moving more toward collaborative and efficient practices, therefore the popularity of design-build is increasing,” says Brian Walsh, CEO of the Collage Companies and president of DBIA’s Florida region.

U.S. 17-92 Over SR 436

TJ Lallathin, the design-build manager for DRMP, has been actively involved in more than 35 design-build projects and notes first-hand benefits of the process. “Previously, there was a big distinction and separation between construction and design staff who worked on conventional design-bid-build projects,” he says. “Design-build has created a better working atmosphere and innovative techniques through collaboration.”

Lallathin and the design-build team implemented a groundbreaking bridge technology using 96-in.-deep, 209-ft-long concrete Florida I-beams to design a 457-ft flyover bridge at U.S. 17-92 over SR 436 north of Orlando. The new design concept allowed for the elimination of a beam line and shoring towers, simplifying the overall traffic control plan.

The bridge design required the unprecedented delivery and installation of the longest (209-ft) single-piece prestressed concrete beams ever fabricated and installed in the United States. Commuters now save 5 to 10 minutes in travel time by using the flyover bridge to bypass the busy intersection. The project was designed and constructed with a $2-million savings and was delivered with a 25% reduction of the project schedule.

“DRMP and Lane are currently working on the SR 528/Innovation Way Interchange with the Central Florida Expressway Authority (CFX). Part of the project is design-build, and the other part of the project is design-bid-build,” Lallathin says. “The roadway and traffic-related elements are design-bid-build, whereas the structural design of five bridge sites, two toll plazas and maintenance of traffic are part of the design-build package—which is interesting because it’s a project with two distinct delivery methods.”

Progressive Design-Build

Walsh notes that another alternative to lump-sum design-build procurement is progressive design-build, which is emerging as a way for public entities to secure design-build contracts where clients receive the benefits of design-build collaboration earlier in the programming and design process.

“One of the differences with progressive design-build is that it allows an entity to get a team involved earlier so they work on the design process and budgets together,” Walsh explains. “This takes the benefits of design-build team collaboration and maximizes those benefits to get the best design and meet budget and schedule requirements.”

Progressive design-build allows for the selection of the design-builder based on qualifications rather than price. The concern that certain public owners may have about a delayed guaranteed maximum price (GMP) can be mitigated as a result of early involvement in the design process by the entire team, which allows risks to be identified and cost alternatives to be explored and incorporated into the project before the documents are completed.

“Progressive design-build is becoming more popular in the transportation and water/wastewater sector,” Walsh says. “Very often, those sectors are driven by a performance model. If a public agency needs a specific amount of roadway constructed in a certain timeframe or a public utility needs a certain amount of water purified within a specified overall budget, then the design-build process and specifically progressive design-build may be the perfect procurement method to achieve success.”

Complex, performance-driven projects in the marketplace are a real sweet spot for design-build. “The AEC service industry is about meeting needs, solving problems and building relationships,” Walsh adds. “And that’s what design-build and DBIA are all about. Design-build is the best team collaboration process, and the DBIA
is the organization that defines and promotes best practices.” ◆
