COMPARISON OF BIM-BASED QUANTITIES TAKE-OFF IN QUANTITY SURVEYING PROFESSION

Quantity surveyor (QS) plays an important role in a construction project who is responsible for the construction cost. Quantity take-off (QTO) will be conducted by QS to measure the quantities of materials needed for the construction project followed by the preparation of bills of quantities (BQ). Building information modelling (BIM) was introduced to the construction industry and brings many benefits to the QTO process such as time saving and high accuracy. However, BIM-based QTO consists of numerous issues such as 3D modelling issues, quantities extraction issues and data loss issues. Hence, this research aims to compare and analyse the application of BIM-based QTO in the QS profession. The objectives of this research cover the comparison of BIM-based QTO in BIM software as well as the analysis of quantities extraction which complies with Malaysian Standard Method of Measurement of Building Works Second Edition (SMM2). This research was conducted by using two types of BIM software which are Autodesk Revit and Cubicost TAS. This research is expected to benefit the QS profession by delivering a better understanding of using BIM for QTO with the analysis and comparison of QTO data.
