Abstract:

In concrete structure projects, activities such as drawing, fabrication, and assembly related to the reinforcement substantially impact the schedules and costs. It is necessary to apply building information modeling (BIM) to smoothly share and distribute information regarding reinforcement among the diverse range of suppliers to streamline work.

This study aims to establish a BIM-based rebar information linkage system applicable across the reinforcement work supply chain. The paper reports on the prototype development and trial of an automated 3D shop drawing generation tool, which is one of the essential tools in the system. Through a trial conducted in a subway station construction project, it was validated that the tool led significant reductions in labor costs and timesaving compared with the conventional 2D-based drawing method. As future work, it will be necessary to define an information model for rebar in order to build a system that can promote information sharing and coordination across the supplier network during the construction phase.
