本文讨论了一个建设项目，该项目涉及在底特律水和污水处理部门（DWSD）的水厂公园建设一座新的240 mgd水处理厂（WTP）。新工厂将降低运营和维护成本，延长使用寿命，并使DWSD能够遵守预期的更严格的水质法规。DWSD认识到，设计/建造方法将鼓励创新，并将显著缩短新水处理厂的项目交付进度，减少现有电厂保持运行所需的时间。为了确保设计/建造商提供低维护、高质量的工厂，决定让承包商负责工厂运营前七年的所有维护。 1996年12月，开始了为期6个月的试点研究，以确定新水处理厂的设计基础。在试点研究期间，确定了项目要求和设计/建造/维护承包商选择程序。进一步的合同条款进行了讨论。

This paper discusses a construction project that involved building a new 240 mgd water treatment plant (WTP) at Detroit Water and Sewerage Department's (DWSD) Water Works Park site. The new plant would lower operating and maintenance costs, have a longer useful life, and allow DWSD to comply with anticipated more stringent water quality regulations. DWSD recognized that a Design/Build approach would encourage innovation and would significantly shorten the project delivery schedule for the new WTP, reducing the amount of time the existing plant would need to be kept operational. To ensure that the Design/Builder provided a low maintenance, high quality plant, it was decided to make the contractor responsible for all maintenance for the first seven years of plant operation. In December 1996, a 6-month pilot study was started to establish the Basis of Design for the new WTP. During the pilot study, the requirements for the project and the Design/Build/Maintain contractor selection procedure were determined. Further contractural terms are discussed.
