Large logistics centers are being built around the world. Most of these buildings have characteristics of long span and heavy load, and use PC (precast concrete) structure for quick construction. There have been few attempts to systematically analyze the various influencing factors of PC erection planning. In this study, we intend to analyze the influencing factors necessary for the creation of a sustainable PC erection planning algorithm.

In reinforced concrete constructions, reinforcing bar generates more CO<sub>2</sub> per unit weight than other construction materials. In particular, cutting and bending rebar is the main source of rebar waste in the construction industry. Rebar-cutting waste is inevitable during the construction of a reinforced concrete structure since the rebar is not manufactured as designed. Large amounts of waste can be avoided by utilizing optimal cutting patterns and schedules. This research provides a fundamental analysis of the automatic calculation of column rebar length using BIM-based shape codes to minimize cutting waste to near zero. By employing this approach in practice, it is possible to minimize the rate of rebar-cutting waste, reduce costs, shorten construction duration, and reduce CO<sub>2</sub> emissions. In addition, the development of this research will serve as a clue for the development of BIM-based rebar layout automation algorithms.
