. Entering globalization era, contractors face many challenges, as the forces to continually adapt the changes in the very high competitive market increase. One of the strategies that is believed can answer the challenges is to improve the efficiency and effectiveness of the business processes by adopting information technologies (IT). The construction industry, like other industries, has entered the information age by using IT in a variety of ways. Yet many construction firms, that have adopted IT, faced many problems related to how to get the best of IT adoption into their business processes. IT is still used merely as supporting tools and there are many limitations to its current use in construction. It is believed that the problem lay on poor management of IT by contractors. This paper discusses a research that has been conducted to identify the critical success factors in managing IT by Indonesian contractors. The success factors were developed based on important and necessary stages ofmanaging IT, i.e. planning, implementation, maintenance, and evaluation. The research used a self-administered questionnaire to collect opinions from 107 Indonesian contractors that are members of Indonesian Contractors Association (AKI) on the importance of each suggested factor in contributing to the successful IT management in contractors\u27 environment. By knowing those critical success factors, contactors can focus their efforts in managing IT to the most significant strategy to reap the benefit of IT in supporting their business process. On the other hand, the identified critical success factors can also be used as variables in evaluation of contractors\u27 performance in managing IT. Furthermore, the contractors can use this evaluation system to measure their performance to the others as a mean to improve their competitive advantages
