ACCO was chosen by Conexant Systems, a world leader in semiconductor products for the communications industry, to tackle one of the most challenging projects in our companies history. 15,000 square feet of clean room fabrication facilities were designed and built in a span of four months.

ACCO led the MEP team in this project, responsible for all design, management, and coordination of HVAC, process piping, plumbing and electrical contractors. Working under a literal “7x24” schedule, the 5,000 square foot class 1 clean room was certified 19 days after the depressed slab was cut. Temporary chilled water, hot water and steam plants were utilized until the long lead permanent equipment was scheduled to arrive.

The 5,000 square foot Class 1 cleanroom project included isolation from existing fab facility, demolition of office areas, and conversion to new cleanroom. The system was comprised of modular fan units with integrated ULPA filtration grid systems, make-up air units insert to fan filter units via Stage 3 protocol, and fabricated and cleaned ductwork.

The 8,000 sq. ft. Class 10 modular cleanroom was constructed within an existing warehouse building. ACCO installed wall, ceiling, raised floor and structural systems in addition to ductwork. Two make-up air units were installed at 40,000 cfm each, and serve recirc air units for sensible cooling.

The central plant expansion consisted of three centrifugal chillers, five cooling tower cells, two hi-temp boilers, one heat exchanger, two unfired steam generators, nine pumps, distributed steam, DDC controls, and primary/secondary pumping.
