At the heart of the University of Vermont’s 19th-century campus, crews led by PC Construction delivered an $80.7-million STEM Complex—the largest facility investment since the Burlington school’s founding in 1791. In three phases over four years, the project team demolished two buildings and constructed two new ones totaling nearly 185,000 sq ft.
The project was not the only one underway during the STEM Complex’s renovation, according to Ryan Sauer, construction executive at PC Construction. “There were three other major construction projects in that area,” he recalls. “It was very challenging working around them and coordinating between the contractors, while also working on an active campus.”
To safely deliver the complex, Sauer says PC Construction had to phase the project. First, the team demolished a 1960s-era lecture hall building, which cleared the way for construction of Discovery Hall—a 111,000-sq-ft teaching and research laboratory building. An 86-ft-long overhead bridge was also erected, connecting the new building to the university’s existing engineering building.
在第二阶段，项目工作人员拆除了这座五层楼的165,000平方英尺的库克物理科学大楼，该大楼距离新建的探索大厅仅30英尺。
The final phase delivered the new 73,000-sq-ft Innovation Hall, a classroom and office building with a five-story connector to Discovery Hall.
The new facility houses dozens of laboratories and clean rooms that required complex mechanical-electrical-plumbing system coordination. The dense systems include large HVAC installations; laboratory plumbing services; unique lighting and electrical distributions; automatic building control; and life safety systems.
该项目包括140多个通风罩，50台实验室长凳，数十个高架服务网格以及校园食用的蒸汽和冷藏水系统。
To coordinate these systems, the team leveraged detailed virtual construction modeling for hangers and supports; accessibility; clearance zones; controls and laboratory casework; and equipment modeling.
在协调过程中，团队还专注于大学的访问和可维护性。根据提交，建筑参与者与学校的维护和运营小组合作，以最大程度地满足新设施的满意度。
为了帮助建筑团队和项目利益相关者更好地了解MEP设计，创建了完整的建筑模型，其中包括高架服务电网，重新加热线圈和相关的控制阀可访问性，实验室长凳和通风罩。
该建筑物的几个区域具有裸露的天花板和金属挡板天花板，因此可见许多MEP元素，例如衣架和支撑，绝缘，火和火和声音密封剂。根据奖项的提交，团队从MEP协调的早期阶段就考虑了这一点，不仅专注于系统功能，而且集中在其组织和外观上。
An extensive building envelope mock-up was also created during concrete and steel erection. It was more than 20 ft tall and placed on a concrete pad that doubled as a mock-up for polished concrete slabs used extensively in the research labs. The mock-up enabled envelope contractors to work through complex and high-performance curtain wall flashing, with composite metal panel and masonry details seen well ahead of construction on the building. The university “has tight standards on [building] envelopes, so mock-ups made sure we ironed out issues with the envelope before we got into the field,” Sauer says.
Throughout the project, the team reached outside the construction fence to connect with the community. PC Construction conducted a variety of classroom presentations and seminars for students on topics such as introduction to construction management, virtual construction and contracts negotiation. The contractor also hosted regular construction site tours with high school, technical school and university students.
从社区的角度来看，科学建筑和STEM建筑物“对社区和社会都是好事。”

Each summer during the project, PC Construction hired a student studying civil or mechanical engineering to participate in the project as an intern. “Bringing in engineering students, doing presentations and touring the site so classes could see what their future is—that’s something that was good for the campus community,” Sauer adds.
一位最佳项目法官指18luck官网出，项目团队“在试图为未来的建筑管理中吸引可能的学生而做了很多事情，这是我喜欢他们所做的事情之一。”
另一位法官指出，该项目不仅仅是校园的好处，强调了科学和STEM建筑的建设“对社区和社会都是好事。”
