This project involves the renovation of a 2,500 sf portion of an existing 1.2 million sf microelectronics manufacturing facility for a major telecommunications client on their Northern California campus. Contained in Building #1, the Fab cleanroom project is primarily an upgrade in finishes in order to achieve a Class 100 Clean Room status. Our work involved the addition of several columns and bases at the basement level to handle added vertical weight and to reduce vibration. A new ceiling will have HEPA filters with Fan Filter Units and tear-drop fluorescent lights at the ceiling grid system. New mechanical equipment will be installed to maintain strict humidity control and sprinkler heads will be relocated as required.
