COST ESTIMATING DATABASE MODEL FOR CONSTRUCTION PROJECT
Cost estimating is one of the most important steps in project management. A cost estimate establishes the base line of the project cost at different stages of development of the project. A cost estimate at a given stage of project development represents a prediction provided by the cost engineer or estimator on the basis of available data. Numerous computer aided cost estimation software systems are now available. However, most practitioners is still using a spreadsheet application to estimate project costs, which is easy to use, but on the other hand is lack of providing the information that we needed quickly, because it stores the data not in database format. This study aims to develop a database model to estimate the cost of construction projects at different stages of project development. The study starts from analyzing the old system is already running, then proceed with developing a process model and database model in accordance with the results of earlier analyzes.
