设计-建造-施工方法为参与施工项目的所有群体带来了机遇和挑战。本文将探讨机电设计师和承包商如何为最近在科罗拉多州丹佛市中心的拜伦·G·罗杰斯联邦办公楼现代化项目应对这些机遇和挑战。该项目涉及对一栋现有高层建筑进行约50万平方英尺的翻修和深度能源改造，预计该建筑将在未来加入国家历史遗迹名录。 项目团队面临的挑战是重建整个机械/电气基础设施，同时维护历史悠久的外部立面，并保持相邻法院的运行，该法院的机械/电气系统由办公楼供电。由于该建筑为多个政府机构提供办公空间，设计-建造团队的任务是协调不同机构的要求和时间表，以完成其空间。这栋大楼的所有者美国总务管理局（General Services Administration）精力非常旺盛- 节约目标；其中一个目标是该项目的照明为100%LED，这是一个挑战，因为2010年缺乏商用LED灯具。项目组由一名总承包商组成，该承包商负责建筑和结构设计师以及机电承包商的合同。机械和电气承包商与各自的机械和电气设计师签订了合同。引用:2016年冬季会议，佛罗里达州奥兰多，会议论文

The design-build construction method presents opportunities and challenges to all the groups involved in a construction project. This paper willexplore how the mechanical and electrical designers and contractors addressed these opportunities and challenges for the recent Byron G. Rogers FederalOffice Building modernization project in downtown Denver, Colorado. The project involved approximately 500,000 square feet of renovation and deepenergy retrofit in an existing high-rise building which is anticipated to to be added to the National Register of Historic Places in the future. The projectteam was challenged to rebuild the entire mechanical/electrical infrastructure while maintaining the historic exterior façade and keeping the adjoiningcourthouse operational which has mechanical/electrical systems fed from the office building. Because the building provides office space for multiplegovernment agencies, the design-build team was tasked with coordinating the differing agencies’ requirements and schedules to complete their spaces. Thebuilding owner, the General Services Administration, had very aggressive energy-saving goals; one of these goals was for the project’s lighting to be 100%LEDs, which presented a challenge due to the lack of commercially available LED fixtures in 2010. The project team consisted of a general contractor,who held the contracts for the architectural and structural designers and for the mechanical and electrical contractors. The mechanical and electricalcontractors held the contracts with the respective mechanical and electrical designers.
