The Terascale Simulation Facility (TSF) at Lawrence Livermore National Laboratory (LLNL), Livermore, CA is a one of a kind leading edge super-computing facility.  Construction value is approximately $57 million.

IBM's Blue Gene/L supercomputer, installed at T.S.F., captured the number one position in the latest iteration of the Top 500 list of the world's fastest machines, at the 2005 International Supercomputing Conference in Germany.

Ackerman-Practicon developed unique new mechanical and electrical concepts for dealing with the unprecedented anticipated loads of more than 310 watts per square foot.  Additionally, the HVAC systems must handle the heating and cooling loads of the office building and ancillary spaces, provide humidification for machine spaces, and ventilation for the entire facility.

Science teams will use the facility as they work during the next decade to assure the safety and reliability of the nationís nuclear weapons stockpile.  Either element -- computation or data assimilation -- will be unparalleled in the world,  and composed of the most powerful technologies available.  When brought together,  these two elements will make possible the quantum leap from computation to simulation even as the program is enabled to meet critical national needs.

The project includes construction of a 268,000 square foot building located adjacent to the existing Building 451 on the LLNL main site.  The building consists of a 2-story main computer structure flanked on the south side by a 4-story office tower.

The main structure will house two computer machine rooms, each with approximately 24,000 square feet.  Both computer machine room floors will have 12í ceiling height to assure proper air circulation, and a 4-foot raised access floor in order to allow adequate room for air circulation, cabling, electrical and plumbing equipment.

The office tower will house space for approximately 288 people.  The space will include meeting rooms, offices, and an Advanced Simulation Laboratory.
