2 Provide a concise project description in the following box (one page maximum). Include the significant aspects of the project and their relationship to the judging criteria. University of Delaware East Campus Utility Plant Newark, DE The University of Delaware serves more than 16,000 undergraduates and 4,500 graduate and continuing studies students. Capacity of the school s central campus utility plant was deemed insufficient to serve estimated existing and future peak cooling loads. In order to support a new science building, a proposed revised housing strategy, and future campus expansion, a new East Campus utility plant was designed and built. Keast & Hood Co. provided structural engineering design for the new three-story (two levels above grade; one level below), 32,000-square foot chilled water plant with 11,000 tons of cooling capacity. The project included: Documentation by all consultants using Revit; the Revit model was also used by the construction manager for clash detection and coordination among trades. Coordination between the utility plant team and the team for the new Interdisciplinary Science and Engineering Building, under construction on an adjacent site. Close coordination between structural engineering and construction management teams to sequence construction phase activities so that large mechanical pumps and other equipment could be placed in the basement/lower level after much of the first level structural steel was in place. Structural challenges included: Structural design to accommodate over 795,000 pounds of mechanical equipment on the elevated floors, including four 2,750-ton chillers which weigh 137,000 pounds each. Reconciliation of issues and concerns related to noise, vibration, and electro-magnetic fields as a result of the utility plant and science building s proximity and simultaneous construction. Development of a structural waterproofing system installed for the entire basement level. The basement/pump level, which houses all large pumps, is located below the groundwater table; the project team studied a basement system to account for the possibility of localized, temporary fluctuations of the groundwater table. Structural provision for hoist beams with capacity ranging from 0.5 to 16 tons for mechanical equipment at all levels; hoist beams are attached to the building s structural steel framework. Structural design to support the high curtain wall. To laterally support a 55-foot wide x 40-foot high glass curtain wall at the front of the building (west side), an exposed horizontal structural steel truss is utilized near mid height of the curtain wall. The truss is placed horizontally behind the horizontal mullions, hung and stabilized by series of hanging rods for aesthetic purposes. Support for two current chillers on an elevated floor structure with reserve space to support two additional chillers. Design of 35-foot high, 300-foot long self-supporting metal screen walls at the east side, surrounding the cooling tower courtyard; the enclosure walls serve as sound barriers and minimize noise from the towers to prevent disturbing students and occupants of nearby research and laboratory buildings.

3 The following 5 pages (maximum) can be used to portray your project to the awards committee through photos, renderings, sketches, plans, etc Night and day views of the new University of Delaware East Campus Utility Plant:
