A Review of India Centric Studies on Factors Causing Time Overruns In Execution of Construction Projects

The construction project process can be divided into three main stages, i.e. project conception stage, project design stage and project construction stage. Generally, most of the project delays take place during the actual construction period, where many unanticipated factors are constantly implicated. In construction, delay may be defined as the time overrun either beyond completion date specified in a contract, or beyond the date that the parties agreed upon for the delivery of a project. There number of construction projects facing widespread delays has increased resulting into excess expenditure and consequent loss of other resources. The intention of this study is to review and identify the applicability of past studies on determining the factors causing time overrun in ongoing construction projects. This paper examines seven India centric studies which have surveyed the delay factors and classified them into groups or categories, done by various researches and agencies in the past decade. The focal point of this paper is to review research which has categorized the causes responsible for time overruns in projects. This review paper attempts to give a restructured compilation of the earlier studies on ranking of the factors causing time overruns, which though not similar, have certain recurrent factors emerging in nearly all the studies thereby indicating the need to address them by devising mitigation measures.
