The objectives of this paper is to introduce a generic computer aided building cost estimation model based on functional elements for Turkish construction sector projects which will be used in feasibility and schematic design phases. The research design was based on the building functional elements method and a building cost estimation model based on functional elements works on a cost database was suggested. Underlying principles and basic steps of cost estimation based on functional elements was explained by means of computer-based cost estimation process. In order to automate the manual building cost estimation process, the software based on functional elements was developed. The software is currently in the testing phase and is being used for educational purposes. Making use of both public sector and current market prices in the cost estimation process, increasing number of projects stored in the database for more accurate results, estimating costs of different types of projects and estimating the structural functional element percent more precisely are suggested for future research. As the number of the similar projects in database is increased, the accuracy of the cost estimation is also increased. Estimators and graduate students can use the software to estimate building cost of residential projects in feasibility and schematic design phases.
