Concurrent Delay Analysis: Methods, Case Law, and Expert Perception

Abstract

Concurrent delays in a project schedule are due to two or more independent delay events occurring during the same time period. There arise difficulties in attributing responsibility for these delays and in deciding the manner in which they are to be dealt with, as they are typically complex and intertwined. While various approaches and professional guidelines are followed internationally, a thorough study in the Indian context is lacking. Hence, it is essential to recognize the nature and effects of concurrent delays that the Indian industry is facing. In this regard, cases in India were analyzed to understand the nature of concurrent delays, strategies adopted, and legal issues. Also, a survey of arbitrators and professionals with experience in delay disputes was conducted to (1) identify current approaches to concurrent delays in India and (2) determine the appropriateness of and challenges in applying approaches from the literature. In India, shortfalls exist in project management processes and protocols. Also, documentation and information management systems are poor. These failings act as barriers to adopting advanced global practices. In this regard, the findings of this work are expected to help in standardizing approaches to concurrent delay analysis and in streamlining necessary process protocols in the Indian construction industry. © 2019 American Society of Civil Engineers.
