This project consisted of two new co-ed dormitories for the University of Colorado. Each building is six stories in the center sections with North and South wings stepping down to five and four stories. Each building is 190,747 square feet for a total of 381,494.
A four-inch high-pressure steam line enters the building to supply heating water to the fan coils and also to heat the domestic 534-gallon storage system. Eight-inch chilled water also is fed into the building for cooling to all of the fan coil units. Heating water pumps are 10-horse power on both primary and secondary systems. Chilled water pumps are 20-horse power on both primary and secondary systems. Both pumping systems are rated for 75 feet of head pressure. The plumbing waste system is a Sovent system completely designed and coordinated by the HPE, Inc CAD department.
All floor penetrations for the plumbing and piping systems were laid out and coordinated using the Total Station. There are over 5000 sleeve penetrations in the two buildings. We are using a combination of ProSet and Hilti fire rated sleeves for the floor penetration to minimize the fire chalking required by code. This project is fast track with the first building to be completed and occupied in less than twelve months and the second building less than six months after.
