Project Characteristics for Successful Public-Sector Design-Build

Abstract

The use of design-build project procurement is rapidly increasing in the public sector. Documented design-build success and imminent changes in federal procurement law are indicators of continued large-scale growth in the public sector. Rapid growth, combined with a lack of long-term experience among many public agencies, necessitates continued investigation of the underlying principles of design-build. Understanding which project characteristics are critical for success is fundamental for improved public agency implementation. To this end, a comprehensive research study was conducted on public-sector selection of design-build. This paper discusses results from a survey of 88 public-sector design-build personnel and structured interviews of federal agency representatives. Five primary project characteristics are discussed: well-defined scope, shared understanding of scope, owner construction sophistication, adequate owner staffing, and established budget. These suggest selection of design-build as an appropriate delivery strategy for successful project completion. Additionally, this paper addresses public-sector criteria of success; these include: staying on budget, conforming to user's expectations, and staying on schedule.
