The wide implementation of Information Technology and Communications (ITC) in construction has proven to be a difficult task due to the inherent characteristics of the construction industry. The introduction of computers, telecommunications and automation is changing the way the different parties relate to each other in the whole construction process. Important opportunities for improving performance on engineering and construction projects may be obtained through the integration of design, planning, and construction. The only way of obtaining these results is through the rational use of information systems, including Internet. This paper analyzes the level of utilization of these techniques in the construction industry and the impact on the flow of information between the contracting parties. From the realized research a model is proposed that fits better the actual relationships that have appeared with the wide use of the Information Technology and Communications in the construction industry.
