One of the most important challenges facing construction project managers today is controlling cost and schedule overruns. Cleanroom projects with their associated aggressive schedules and budget limits present management with the tremendous task of tracking resources and developing timely and efficient schedules. A cost and schedule control system must be devised to deliver these projects successfully on time and within budget. Based on a research survey conducted among twenty-two construction management professionals involved in cleanroom construction from general contracting companies and construction management firms, this article defines how construction cost and schedule controls for cleanroom facility projects are accomplished and identifies the keys for effective construction cost and schedule control.
