As building systems have become more complex, selecting an efficient system for finding the optimal solution in the construction of high-rise building structures has become crucial. To obtain more optimized design solutions and reduce the waste caused by the rework that frequently occurs in Point-based Design (PBD) procedure, Set-based Design (SBD) procedure was recently proposed, and its application to design practice has been extensively studied. However, more research on the design procedure application details is necessary. This research focuses on improving the SBD procedure by the efficient selection of alternatives. The proposed design procedure uses Structural Building Information Modeling (S-BIM) to increase the efficiency of this selection and obtain more optimal solutions to eventually improve the constructability, structural safety, and economic feasibility of the building. The case study in the last section shows that the proposed design procedure achieves higher efficiency than SBD based on existing 2D method in selecting alternatives.
