SBC Internet Data Center in Irvine, is a $100 million world class hosting service facility providing customers with a client-ready environment in which clients can install their computer server equipment. This facility consists of the very best in security, power, and air conditioning with complete (N+1) redundancy for all systems to ensure an optimal computer server environment. The complexity of the HVAC systems and rigorous completion schedule was met by ACCO's vast resources and expertise.

The 149,121 square foot facility is comprised of a 102,500 square foot raised data floor (designed for a potential load of up to 100 watts per square feet), network operations center, redundant electrical distribution rooms, administration spaces, executive conference rooms, and customer utilization areas. Cooling for the highly sensitive electronic equipment and support facilities is made available from a 3,040 ton chilled water central plant.

Working under a three month completion schedule form start to turn key, ACCO's engineering and construction team worked two shifts, seven days a week, and was able to deliver a complete working HVAC system on time, and most importantly, under budget. The ACCO pipe fabrication and sheet metal shops were able to deliver material, dependably, from accurate onsite AutoCAD fabrication drawings and kept the large ACCO crews installing.

acco's dedication and commitment to providing the safest work environment possible resulted in zero "lost time" injuries on this 36,000-man hour project.
