EOT Claim Management System using Building Information Modelling

Abstract

Delays are an integral part of construction projects. In case of delays caused by reasons that are not in the control of the contractor, the contractor is entitled to Extension of Time (EOT) after the approval by the stakeholders involved. EOT Claim is one of the leading causes of disputes in construction contracts. EOT Claim generation is a lengthy process that involves specialised skills and knowledge of construction contracts. Building Information Modelling (BIM) is an emerging area of study and practice in the construction industry providing automation in a large number of construction processes. The following study focuses on the development of an Automated EOT Claim Management System that is capable of calculation of delays and EOT entitlement to contractors by using As Planned vs. As Built method of delay calculation and analysis. The system is built with the aid of a visual programming framework supported by Autodesk Revit called Dynamo. The developed plugin is capable of calculation of EOT Delays, generation of EOT Claim Document and visualisation of delays in 3D and 4D. The system aims at automating the process of EOT Claim generation by minimising human efforts.
