以前对建筑、工业和交通项目的研究发现，使用设计-建造方法交付的项目往往比使用传统设计-投标-建造方法交付的项目表现更好。然而，设计-建造项目的绩效受到各种因素的影响，其中与采购有关的因素是最具影响力的因素。虽然采购的其他方面已在很大程度上进行了调查，但采购期限对项目绩效的影响只针对设计-建造运输项目进行了研究。此外，很少有研究专门侧重于水/废水项目的交付。本文包括水/废水设计建造项目的采购时间和性能之间的关系的研究结果。研究方法是基于对水/废水设计-建造项目样本数据的回归分析。结果表明，与交通运输部门，采购时间对水/废水部门的进度或成本性能的影响很小。随后通过对采购文件的内容分析，探讨了造成这一差异的可能原因。
Previous studies on building, industrial, and transportation projects found that projects delivered using design-build tend to perform better than projects delivered with the traditional design-bid-build method. However, performance of design-build projects is affected by various factors, with procurement-related factors being among the most influential. Whereas other aspects of procurement have been largely investigated, the effect of procurement duration on project performance has been studied only for design-build transportation projects. In addition, few studies have focused specifically on the delivery of water/wastewater projects. This paper includes the results of a study on the relationship between procurement duration and performance of water/wastewater design-build projects. The study methodology was based on regression analysis of data from a sample of water/wastewater design-build projects. The results show that unlike the transportation sector, procurement duration has little effect on either schedule or cost performance in the water/wastewater sector. Likely reasons for this difference were then explored through a content analysis of procurement documents.
