“I think we’ve been able to demonstrate that we’re taking lessons learned and rolling them forward to gain efficiencies,” Leitner says. “We hope that every project that comes out will be better and better. I think that’s our mission here.” PAUL A ANDRUSS IS A CINCINNATI-BA SED WRITER WHOSE WORK HAS APPEARED IN DELIVER, THE MAGAZINE OF THE USPS; MARKETING NEWS, THE MAGAZINE OF THE AMERICAN MARKETING ASSOCIATION; AND OTHERS. SHE WROTE ABOUT THE SOUTH ADAMS SCHOOL DISTRICT IN THE SPRING 2011 ISSUE OF IQ . PERFORMANCE-BASED REQUIREMENTS: A DESIGN-BUILD BEST PRACTICE Making the shift to design-build for the first time can be a shock to any facility owner. There are fundamental differences between the traditional delivery method of design-bid-build and designbuild when it comes to attitudes, knowledge bases, procedures and processes. This learning curve can be particularly challenging for owners moving away from the prescriptive specifications designbid-build relies on to the performance-based requirements that leverage the most value from a design-build project. Many public owners use “bridging” in an attempt to avoid a full-blown conversion to performance-based requirements. This is a version of design-build in which an owner hires an A/E firm to develop a partial set of drawings that shows approximately 30 percent of the project’s design. The owner inserts these drawings in the RFP and holds a design-build competition in which teams compete to price finishing the drawings and constructing the building. The use of extensive prescriptive design via bridging documents eliminates many of the advantages inherent to design-build delivery by reducing the potential to create greater value for the owner through early contractor involvement and team-based creativity. Key solutions and concepts are determined before the design-build team begins work. Bridging decreases an owner’s ability to obtain innovative and divergent solutions derived from the design-build procurement process. Performance-based requirements, on the other hand, allow the owner to create narrative performance requirements rather than drawings. Performance requirements describe the overall performance of a building. The owner can create high-level requirements such as “Design and construct a zero net energy building” and can also require details such as “Provide design calculations for the structure of the building.” Performance requirements support the art of innovative design and the science that provides quality control for the owner. Moreover, the use of this DBIA best practice can fulfill the owner’s needs when it comes to budget and schedule. What the owner doesn’t do is tell the designbuilder how to reach the project goals. This fundamental shift in responsibilities creates a struggle for many facility owners. In designbid-build and to a certain extent in a bridging design-build scenario, owners control the details of design and construction. In design-build, that responsibility and liability rests with the designbuilder—the entity most capable of providing those services and managing the risk. As owners become more comfortable with writing and overseeing the implementation of performance requirements, opportunities to achieve stellar facility, like the Research Support Facility, will grow immeasurably. Design-build is oriented towards results: a net-zero energy facility, projects completed on time and on budget with the quality that an owner needs. One final outcome that shouldn’t be overlooked: the simple joy of working on a designbuild project. LEANDRA THOMPSON IS THE PRESIDENT OF AURORA, COLO.-BASED NORTHSTAR PROJECT MANAGEMENT INC.
