1. Constructability refers to the achievement of project objectives through the optimum use of construction knowledge and experience in planning, design, procurement, and field operations. This article proposes a conceptual framework called Total Constructability Management (TCM) for integrating the constructability and project development processes.

As building construction projects have become more complex and larger in magnitude, enhancing the interface between the design and construction has become more important for their successful completion (Kwon and Kim 2003). Most decisions in the pre-construction phase affect the construction performance (Pulaski and Horman 2005), and those impacts increase with the projects’ size. However, the traditional procurement approach tends to separate the design from the construction, which hinders contractors from providing designers with suggestions and feedback, based on their construction expertise during the design phase (Lam et al. 2006). In addition, many designers have indicated that failure to consider constructability is a major problem in the design process (Bae et al. 2006). This leads to increased waste, e.g., design changes and reworking in the construction stage, as well as losing opportunities for design enhancement (Motsa et al. 2008).

Thus, continuous efforts have been made to minimize the fragmentation between participants and to make better use of construction knowledge in the design process. The Construction Industry Institute published guidelines for implementing constructability programs (CII 1993), and Singapore introduced the Buildable Design Appraisal System for making more buildable and labor-efficient designs (Poh and Chen 2010). Several programs, e.g., design reviews, constructability reviews, and value engineering, have been introduced to enhance the design quality and project performance (Pulaski and Horman 2005; Park et al. 2009; Li et al. 2018).

Although these methods have led to improvements in project performance, they are relatively unsophisticated and inefficient and rely heavily on reviews. In addition, existing approaches tend not to consider the appropriate timing when applying knowledge or the level of detail for efficient decision-making in the design process (O’Connor and Miller 1995). This can result in productivity loss by frequent reworking at the design stage, as well as adversarial relationships among the participants. Thus, to utilize constructability knowledge effectively, the right information at the proper time should be provided to the design team. The information should also have appropriate levels of detail to enable its successful integration with specific design activities.

This study proposes a process model for integrating constructability activities (CA) into the design phase in high-rise concrete building construction. In this study, the CA focuses on the temporary work including facilities, equipment, and construction methods. This is because there have been lack of efforts and attempts to enhance the constructability of temporary work from the design phase, even though this can greatly affect the construction efficiency of permanent structures as well as cost and time during the construction phase. The model organizes activities for constructability improvements based on appropriate timing and detail levels. The proposed model considers the information-exchange efficiency and minimizes overlapping activities in the design process.
