Twenty-first century project delivery systems

摘要

The future of construction project delivery involves a variety of delivery systems, but far less reliance on design-bid-build as the dominant project delivery system. Construction management at-risk has overcome conflicts between the contractor and the design professional and created an environment in which the manager and the architect/engineer constructively collaborate to achieve a sound design. The use of design-build will increase as the single point of responsibility, faster delivery times and more predictable costs attract more adherents. The scant empirical evidence and short history of build-operate-transfer projects in the United States and abroad have yet to prove its viability as a routinely used alternative project delivery system. But with shrinking budgets and the advantages of working with the private sector, governmental entities are increasingly looking to privatization, public-private partnerships and other creative arrangements to help meet future infrastructure needs. Although there is some indication other methods have outperformed design-bid-build, no one would contend that any one method can be used to perform all projects, particularly those to meet our infrastructure needs. Given that much of the impetus and significant capital for the use of alternative project delivery methods through ISTEA and TEA-21 has been provided by government it is far more likely that we will witness a shift toward the flexible use of all delivery methods." Implicit in this prospect is the proposition that both the public and private sectors can deliver projects in acceptable fashion.
