Network Appliance Dedicated Lab – RTP Building 4
This dedicated lab facility contains over 2,100 racks of data equipment, with the lab environment designed at over 650 watts per square foot. Over 11,000 tons of cooling capacity is delivered by four (4) 2,800 ton centrifugal chillers served by 8 cooling towers. Chilled water runs through the coils of eighty (80) 45,000 CFM air handling units which deliver a collective 3.6 million CFM to the laboratory environment. The structural steel frame is clad in architectural metal panels with weather-proof relief air louvers surrounding almost the entire 3rd level, dedicated solely to the air handling equipment and half of the electrical distribution gear.

Concord EFS

Concord EFS, acquired by First Data, provided ATM, credit card, and payroll pressing services. The 107,000-SF facility provided full-time backup for the Wilmington, Delaware office, featuring 32,000 SF of raised flooring with 2-foot deep access flooring cable and 75,000 SF of office area.

Located across from the Dobbins Air Field, special precautions were taken to reduce outside noise infiltration. Triple-glazed Trainer glass out of Chicago was used to achieve maximum noise reduction.

Redundant N+1 MEP systems increase reliability and ensure the building is always fully operating.

NCAR-Wyoming Supercomputer Center

The three-story, 170,982 sf NCAR-Wyoming Supercomputing Center (NWSC)  is a high-performance scientific computing in the atmospheric and related geosciences fields. The facility includes 16,000 sf of Administration space, 3,600 sf Network Operations Center, 2,300 sf of Mass Media Storage as well as a 100,00 sf Central Utility Plant.

Once full operation begins in the summer of 2012, the NWSC will continue to advance scientific discovery for the next several decades. The adaptive design and construction enables the facility to expand in accordance to the evolving nature of supercomputing technology.

The NWSC’s design takes full advantage of Cheyenne’s elevation and cool, dry climate by employing ambient air to cool the facility nearly year round. This will significantly reduce the facility’s energy use. The facility is estimated to be 90 percent more energy efficient than typical supercomputing centers and is on track to receive LEED Gold Certification. In addition, over 70 percent of the construction materials are reused onsite or recycled.

Methodist Hospital for Surgery

Methodist Hospital for Surgery is a 105,000 SF surgical hospital located on a busy North Dallas corridor.

Methodist Hospital for Surgery is a joint venture partnership between area physicians, Methodist Health System and Nueterra Healthcare.

Rogers-O’Brien managed the entire construction process using BIM, resulting in more pre-fabricated systems, less rework, faster schedule, lower cost and a higher quality building delivered with a 4-month accelerated schedule.

The Methodist Hospital for Surgery received the AGC Texas Building Branch Outstanding Construction Award and the TEXO Distinguished Building Award.
