With recent rapid advancement of BIM technologies, recognized research work for
Utilizing BIM has been conducted for increasing construction efficiency. However,
most of the previous studies were limited to reflect that why applying BIM is
difficult. This study compares the efficiency of BIM according to the type of public
buildings. Because public buildings are built a lot
Ⅰ. Introduction
1. Study background and objectives
Recently, due to environmental pollution and climate change, attention to environment is more growing than ever. Especially, buildings form 40% of energy and resource consumption, 30-40% of carbon dioxide emission, 20-25% of waste discharge, 17% of water consumption, and 25% of wood consumption, so buildings are mainly responsible for
