Abstract
Delays in construction result in a multitude of negative effects on project performance, and severe dismays among participating parties. This study aims to digitize the traditional process of recording and managing the construction delays using Building Information Modeling (BIM). Extensive literature review followed by semi-structure interviews of 21 industry experts were carried out to identify the issues faced by construction stakeholders in managing construction delays. To resolve these issues, a plugin named BIM-based Construction Delays Recorder (BIM-CDR) is developed using Application Programming Interface (API) of the most commonly used BIM software i.e. Autodesk Revit. BIM-CDR provides a centralized repository, encompassing detailed information related to delays, which can be retrieved and visualized to analyze their impact on delay claims. To assess the effectiveness of BIM-CDR, a feasibility study is conducted with the experts’ review panel. The results revealed that BIM-CDR can record wide-ranging information related to all the significant issues causing delays on construction sites, and can help in effectively managing their corresponding claims. The advantages of the developed prototype include visualization of delays’ location, facilitation of delay analysis and effective delays management. Moreover, it also promotes transparency and speedy settlement of delay related claims without any unwanted disputes.
Highlights
Delays are recognized as the fact of life for construction projects (Braimah, 2013)
Various factors leading to delays in construction projects include, but not limited to, unrealistic contract time, improper resource planning, unforeseen conditions, delay in issuance of drawings, errors in documentations, rework and improper risk distribution (Hanna et al, 2017; Larsen et al, 2015)
An extension of time (EOT) and/or additional cost are claimed by the contractor, for the reasons which are not contractor’s responsibility (Kumaraswamy, 1997)
Summary
Delays are recognized as the fact of life for construction projects (Braimah, 2013). Delays can be attributed to lack of management skills and poor coordination among key stakeholders (Farrow, 2007). These delays result in multitude of negative effects on project performance, including additional time and cost to complete the project. To compensate these losses, an extension of time (EOT) and/or additional cost are claimed by the contractor, for the reasons which are not contractor’s responsibility (Kumaraswamy, 1997). There are certain existing challenges that hinder the accurate and efficient analysis of construction delays, which are discussed in the ensuing sub-section
