In a preliminary stage of architectural design, many case studies or collection of experience-based information on construction cost are required, because the decision made at the preliminary stage almost determines construction cost of the building. The authors, therefore, think that it is useful for designers to gather material on construction cost using optimum design method. In this paper, we propose an approximation formula to predict total optimum steel weight of 3D steel frame models with arbitrary brace placement.
