Technical advancements in construction over the years have allowed us to build faster, safer and bigger. But the goal remains the same- completion of a quality product on time and within budget. To achieve this goal, the management needs to know the progress of the project in a timely and accurate manner. That is how the project progresses, where they are currently in comparison to the initially set plans, whether the deadlines are met, budgets are respected etc. Managing a major project is almost impossible without a comprehensive management plan and a functional Construction Management Information System (CMIS), which is dynamic in nature. The present paper aims to develop a system for the project personnel in construction projects to collaborate on Web to improve the management of the exchanged information. CMIS is a tool to help the project manager as the decision maker in the project site. This system will provide the information needed by project manager to execute his job. CMIS is based on database. The scope of this dissertation is to analyze and systemize the information needs of project personnel in Building Construction Department and apply CMIS to enhance the problem solving and information management abilities of construction site management personnel. The project planning and scheduling has been analysed using the commercial software package Primavera Project Planner. A web based approach has been chosen for CMIS implementation. This approach allows the user to access CMIS from anywhere with user name and password through the internet. It provides several user interfaces which are not new for the construction personnel. CMIS just transfers these user interfaces into an online system. Finally CMIS is applied to a live project, as a case study.
