Pubuc-sector design/build evolution and performance

Design/build project delivery is experiencing expansive growth in both the private and the public sectors. Owners are driving the change away from the traditional design/ bid/build method. This change and changes in federal procurement laws necessitate investigation, formalization, and development of new design/build guidelines and practices. Public-sector use of design/build represents a fundamental departure from traditional competitive, low-bid procurement procedures. Understanding the evolution and current trends in public-sector design/build provides a foundation for developing uniform guidelines and practices. This paper describes the rapid evolution of public-sector design/build and analyzes results from 104 completed public-sector design/build projects. The results provide insights for owners, designers, and builders into the changing public-sector procurement system. Items analyzed include owner experience, level of design completion, design/builder selection, contract type, method of award, and design/build process variations. The research conclusions provide a design/build benchmark for public-sector agencies.
