Efficiency analysis of Set-based Design with structural building information modeling (S-BIM) on high-rise building structures

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. ► The SBD process can be used to determine a lean design for structural engineering. ► The SBD process can lead to an improvement in productivity through collaboration. ► S-BIM can facilitate the sharing of information and efficient collaboration. ► The existing SBD with the 2D method, ALT 2 was selected as the design alternative. ► ALT 1 was selected as the optimal solution if SBD method is used.
