Abstract/Contents

Abstract: This paper presents a method to quickly and accurately estimate steel frame material, fabrication, and erection cost based on early design information. The proposed method utilizes a secure web portal that enables suppliers to provide current unit cost data. The method also includes an automated connection detailing component that provides the quantities required for a detailed steel frame cost estimate based on the unit rates provided by the supplier. We apply the estimation method to a simple moment frame and illustrate the difference between a frame designed for least-weight of steel, and one designed for least cost. The results show that the least-cost frame realized a 14% cost savings over the least-weight frame while adding 7% to the total steel tonnage. These initial results demonstrate the potential of the method to improve early stage design decision-making through better vertical integration of project information in the AEC industry.
