Abstract
Tact scheduling is accepted as an efficient method that can reduce idle times during construction. To achieve an optimized tact system, various conditions should be satisfied. Many existing studies addressed various aspects related to applying tact system on construction job-site, including 1) crew balancing by working site rotation in a condominium construction with multiple buildings, 2) the tact system involved in synchronizing a single type of crew on finishing work, and 3) the development of a scheduling model of structural framing construction by working space zoning in a high-rise building. However, no existing studies attempt to apply the tact scheduling method to the structural framing construction for the single building having multiple units. Therefore, this study develops the optimization model and presents its application, which can schedule the tact system for a high-rise building. It is concluded that the proposed method can efficiently optimize the tact scheduling in case of multi-crew to milti-process model.
