ABSTRACT
Contamination Control, which has a direct impact on the productivity and profitability of the manufacturing process, is the central concept around which all cleanrooms are designed, built, and operated. Various internal contaminants, from people and the manufacturing process, and external contaminants, from outside makeup air, cause a variety of potential contamination problems to the materials, processes, and products in cleanrooms. Many of the contaminants in an operating facility might also be attributed to activities during the construction stage of the project.
To help control construction contamination, two cleaning methodologies have been used. One method is to clean the facility at the end of the construction, called "final super clean," while the other method, called "clean-build," requires continuous cleaning during construction. The "clean-build" method is the most widely used contamination control method; however, very little is known about the actual benefit of the "clean-build" approach versus the "final super clean" approach.
This research, through a survey process, compares the two construction methods and outlines some general relationships regarding use of a particular contamination control method and cost, schedule, and cleanliness class conditions. This research also outlines the perception of industry professionals towards the necessity and adequacy of current "clean-build" protocol practices.
