Extension of Time Claim Management Using Building Information Modeling

Delays are an integral part of construction project and result in a multitude of adverse effects on project performance leading to dismays among the stakeholders. In the case of delays caused by reasons beyond the construction contractor’s control, the contractor is entitled to an Extension of Time (EOT) after the approval by the stakeholders involved. EOT claim generation is a lengthy process that involves specialized skills and knowledge of construction contracts. Building Information Modelling (BIM) is a well-established field at the crossroads of simulation, modelling and analysis of construction projects. This study focused on developing a software solution for EOT claim management, capable of calculating delays and EOT entitlement to contractors as per the ‘As Planned vs. As Built’ method of delay analysis. The developed tool allows the calculation of EOT delay along with its visualization in 3D and 4D environments. The approach aimed at digitalizing the process of EOT claim management by minimizing human efforts.
