Application of Building Information Modeling to Analyze Rebar Cutting Patterns with Minimum Waste



Reinforced Concrete Buildings, Minimum Rebar Waste, Building Information Modeling, Linear Programming Model


The problem encountered in constructing reinforced concrete buildings is a large amount of rebar scrap wasted due to the inefficient use of rebar cutting patterns. As a result, the project costs are higher, and the country's economic deficit from rebar imports increases each year. This study presents the interconnection of two data sources, Building Information Modeling (BIM) and Linear Programming Model, to analyze and find effective rebar cutting patterns to minimize rebar waste and cost. Rebar data from BIM was exported and analyzed the cutting pattern to minimize the scrap. Later the rebar cutting data were imported into the parameters of BIM elements. The results from the study showed that rebar scraps were successfully reduced from the cutting process. This study had at least two significances. In terms of construction, it effectively used resources, reduced the construction cost, and avoided the rebar waste smuggling problem from the construction site. In terms of educational value, this study can also be used to calculate standard length rebar, which is cut into several lengths. In addition, importing the cutting data back to the BIM model can reduce the time and mistakes in the operation.
