Development of Estimating Tool for Transportation Project Design

The development of an estimating tool to assist New York State Department of Transportation (NYSDOT) managers is described. The tool was developed using Microsoft Access. It enables managers to input project characteristics and then search a data base of historical projects. The estimating tool returns the staffing levels for similar completed projects. The system was also developed to allow newly completed projects to be added to the data base and to allow for the monitoring of design hours expended for projects that are in progress. Regression analysis was also explored as a means of predicting total project design hours. With the assistance of NYSDOT experts important factors that influence required design hours were identified. Estimating tool users can make a regression prediction for the total project hours using historical projects as input data.
