Fermi National Accelerator Laboratory decommissioned the Tevatron particle collider, which was the largest in the world and now replaced by the Large Hadron Collider. The Tevatron was at the leading edge of scientific discoveries including finding nature's heaviest elementary particle: the top quark.

The new Office, Technical, and Educationbuilding (OTE)merges with the heart of the decommissioned Tevatron, the Collider Detector Facility (CDF),to form the epicenter of theIllinois Accelerator Research Center.

Thissymbolic relationship between new and old is achieved by bridging the office component from a main base, and embracing the existing building along the south.The new structureis 48,000 square feet on three floors and includes; offices, conference rooms, light technical laboratories, a two story lunch room overlooking the campus,and a 180 person lecture hall to hold domestic and international seminars and conferences.

The OTE incorporates a raised access floor system, underfloor air distribution, anda demountable partition system to support a diverse array of rotating tenants providing highly flexible space.The combined buildings provide a state-of-the-art facility for research, development and industrialization of advanced particle accelerator technology. The building received a LEED Gold certification.
