AUTOMATION OF PROGRESS PAYMENT ASSESSMENT OF A CONSULTANT QUANTITY SURVEYOR IN SINGAPORE

Abstract

As one of the most promising developments, 5D Building Information Modelling (BIM) has numerous benefits and enables the possibility of automating the costing process. Prior research efforts have largely focused on 5D BIM using secondary software on other Quantity Surveyor (QS) costing activities with minimal attention given to progress payment assessment by consultant QSs. Nevertheless, the adoption of 5D BIM solutions is low with poor perceptions of 5D BIM within the industry. This paper proposes an add-in to existing BIM authoring software, Revit, to help with the assessment of progress payments by consultant QSs with the help of PyRevit to create the plugin. The proposed system integrates quantity information from the BIM model through the Application Programming Interface (API) in Revit with costing data to automate progress payment assessment for the consultant QS. Using the proposed tool, QS can assess progress payment claims from contractors easily through a simplified process. The research also provides a progressive solution for QSs in Singapore to adopt digital solutions without excessive demand from their technological skillset.
