Arc Flash Evaluation – Multipurpose Research Facility & Computational Science Building

Project Specifications

Project Type
Arc Flash

Area
597,000 GSF

Fosdick & Hilmer was engaged to evaluate the design and construction of the energy systems to determine if energy reductions were possible. Each of the critical energy systems has redundant capacity. Working with UT-Battelle personnel Fosdick & Hilmer recommissioned the electrical power systems and provided additional power monitoring capabilities. As one of the commissioning functions, Fosdick & Hilmer provided arc flash analysis and labeling of the building systems.

Building 5300 is a 227,000 SF, $42.8 million Multipurpose Research Facility (MRF) designed to provide Oak Ridge National Laboratory a consolidated and integrated multi-disciplinary computing facility with the infrastructure and secure environment needed for defense and homeland security computing. It provides space for weapons nonproliferation research, training, and operations; cyber security research and development; geospatial analysis; inorganic membrane research and prototyping; and other research areas. The building systems had a bus count of approximately 490.

Building 5600 is a 370,000 SF laboratory, office and data center building (Building 5600). Computational Sciences Building houses the nation’s largest open use supercomputing facility (40,000 square feet) and includes the processing cores for Titan, the second fastest supercomputer in the world, the fastest academic machine in the United States. The building system had a bus count of approximately 348.
