PROJECT DESCRIPTION
Union Pacific Railroad’s headquarters building, Union Pacific Center, is a 19-story gleaming glass cube successfully designed to create an attractive and comfortable work environment for over 3,500 employees.

Alvine Engineering’s contribution to the project involved a multidisciplinary approach to solving problems and meeting Union Pacific’s goals for their headquarters. This breathtaking facility houses a training center, 600-seat restaurant, fitness facility, and an executive parking garage.

PROJECT HIGHLIGHTS

• Under-floor air distribution system is supplied by individual floor air handling units with manually adjustable swirl diffusers located at each occupant’s work station and in common areas. To address rooms with varying load conditions, such as conference rooms, floor swirl diffusers with motorized dampers were used to vary the amount of supply air for cooling.
• Four air handling units are located on each floor to ensure each workspace is within 80 feet of an air source. The use of industrial-grade pressure controllers was required to maintain precise control of fan speed to maintain underfloor air pressure and reduce energy consumption.
• The 19-story glass atrium, a public lobby in the center of the building, allows daylighting to reach the interior of all floors. The office spaces utilize indirect light fixtures which offer uniform light levels with visual comfort for computer users and minimal glare.
• Carrier class facility, the 35,000-square-foot data center rivals the largest communications companies in the nation and is a central hub for all voice and data communication for Union Pacific Railroad.
• American Council of Engineering Companies (ACEC) Nebraska 2005 Honor Award recpient.
