Building Information Modeling Application in Small and Medium Enterprises (SME) Real Estate Business Case Study Developed Housing Project in Chiang Mai
Abstract:
At present, Building Information Modeling (BIM) is a technology playing an important role in construction industry in Thailand, starting from design to construction use. A lot of large real estate companies have begun to use the BIM to streamline their work processes, while real estate businesses in the sense of Small and Medium Enterprises (SME) have limitations with availabilities of capital, technology and personnel; hence, the BIM has not been plentifully found to be applied in their organizations. Therefore, this research aimed to study possibility of applying BIM technology to SME- sized real estate businesses by using projects of housing development in Chiang Mai as case studies. The research was conducted to compare conventional duplication with BIM From the research on duplication of material quantity of both methods, it was found that work of duplicating RB6 quantity of footing work had difference of percentage value as 12.81, column work as 11.85, and beam work as 0.33. For quantity of DB12 the footing work had difference of percentage value between the two methods as 3.68, column work as 0.33, and beam work as 10.24. In a case of duplicating 210 ksc concrete quantity, it could be divided into sub-tasks as follows: differences of percentage values between the two methods of footing work, beam work, column work, and floor work were 2.50, 2.60, 1.30 and 10.30 respectively. In a case of structural steel quantity, a stud beam steel had difference of percentage value as 0.86, a purlin steel as 1.95, a rafter steel as 3.07, and a hip rafter steel as 4.3. Finally, wall material quantity was a Mon brick had difference of percentage value as 7.56, and quantity of painted area as 6.82. Furthermore, the findings revealed that quantitative duplication by using conventional system is not as good as by using BIM system. Main causes of quantitative duplication were as follows: 1) For the convenience of duplicating quantity, 2) Deficient or impaired thinking was a limitation in memory capacity of workers. 3) It was essential to reserve material quantity since construction processes wasted materials such as breakage or damage.
