Application of building information modeling to rebar management for developed housing project

Abstract

Nowadays, Building Information Modeling (BIM) is the new technology which play more role in Thailand construction industry from design stage through operation/maintenance stage. Many large real estate businesses have been applied BIM to improve their operation for efficiency increasing. But small and medium enterprises (SME) real estate businesses which have limitation in capital, technology and manpower, cannot adopt BIM in their operation. Therefore, this research has the objective for study the possibility in BIM application in SME real estate business by using one developed housing project in Chiang Mai province as a case study. BIM application in this research use in constructability checking and estimating step of 1 type houses: less than 200 sq.m. Which will apply BIM technology for construction work in the form of reinforced steel cutting methods. Because the program makes this research more accurate in terms of calculations that are close to the actual use. From the study, it can be concluded that BIM can reduce the steps and loss of rebar in operating costs in these steps. Demonstrated the potential of BIM to be used to assist in the steel cutting process to have a minimum loss rate. This will save a lot of construction costs and help protect the environment by making good use of resources.
