The Performance Based Studies Research Group (PBSRG) at Arizona State University was organized by Dr. Dean T. Kashiwagi in 1992. The PBSRG is the only construction performance information center in the United States. The concepts of “Fuzzy Logic”, management of information, and artificial intelligence are used to evaluate the performance of contractors and construction systems. Research is conducted on contractors, materials, services, and construction systems procurement. The PBSRG is the research center of the Performance Based Procurement System (PBPS), which will be the procurement system of the futuristic in- formation age.

The PBSRG conducts research in many construction disciplines but the bulk of the research to date has been in the area of commercial roofing systems. Contractors wishing to differentiate themselves from their competitors on criteria other than cost, work in conjunction with the PBSRG to have their performance qualified. The performance information collected by the PBSRG on roofing contractors comes from personally inspecting 50 actual roof installations and interviewing the contractor’s customers. This data is then compiled into an engineering report called a Performance Line. Associated Applications of Vicksburg, Michigan has been a research partner with the PBSRG for the past 8 years and has proven itself to be a contractor committed to providing a high level of service and quality to its customers. Associated Applications has 100% customer satisfaction.

Performance Based Procurement System (PBPS): The PBPS was developed by Dr. Dean T. Kashiwagi to assist facility owners in buying the best performing contractor services/facility systems in a competitive bid environment using all the concepts of “Information Measurement Theory” (IMT). It allows a facility owner to correct facility problems with the best solutions, purchase performing systems, and select the best performing contractors at a competitive price. The system is self documenting, contains its own justifications, and the information generated by the system resolves protests and disputes. It minimizes liability and transfers that liability to the performing contractors through the use of performance information.
