Process for Integrating Constructability into the Design Phase in High-Rise Concrete Buildings: Focused on Temporary Work

With the increase in high-rise building construction, failure to consider constructability in the design phase can result in huge wastes in the construction phase, as well as losing opportunities for design improvement. However, existing approaches for reflecting constructability rely heavily on reviews, resulting in an inefficient decision-making process. Thus, by considering appropriate timing and detail levels when applying construction knowledge, this study proposes a process for integrating constructability activities related to temporary work into the design phase in high-rise concrete buildings. Through an investigation of information-dependency relationships, 22 constructability activities were linked with 33 design activities. Further, these activities’ implementation processes were constructed based on optimized information flows from a partitioned dependency structure matrix. The results of this study can help a project team address constructability issues at the appropriate time during the design process and will contribute to improving the efficiency of the overall project operation in high-rise building construction.
