Clash Detection in Construction Drawing of High-rise Residential Building Using Building Information Modeling

Abstract

High-rise residential building has to comply with multiple strict laws and regulations. Since there are many different programs, which lead to design complexity and many parties involved, then conflicts are often found. If the conflicts are not corrected during pre-construction phase, these conflicts will affect the construction phase. Meanwhile, Building Information Modeling (BIM) is the concept, which was developed for design and construction building process including clash detection. Therefore, this research aims to study the clash detection in construction drawing of high-rise residential building by using Building Information Modeling. The research was done by selecting 5 projects as the case study, studying for building components causing clashes in construction drawing, setting up the clash matrix which contains 903 clashes from various groups of building components, examining the clashes, classifying the clashes for clash issues, ranking the clash issues, and summarizing the study.

The study found that the average number of clashes from 5 case study projects is 301,327.20 clashes per project. The clashes were further classified into different sections of the building. It showed that the most average number of clashes was found in residential floor section, which equals 252,584.80 clashes per project or 78.52% of the whole project clashes. Thus, the clash detection in residential floor section was settled as the scope of this study. From the study, the top 3 clashes that were found in residential floor section are clash between wall from architectural works with piping from sanitary system, clash between wall from interior architectural works and piping from sanitary system, and clash between ceiling from interior architectural works and piping from sanitary system. The average numbers of those clashes are 8.4, 8.2, and 5.4 issues per project respectively. The results will be beneficial for parties involving in design and construction of residential building as database for clash detection using Building Information Modeling for the up-coming projects.
