IDENTIFICATION OF FACTORS CAUSING TIME AND COST OVERRUN IN CONSTRUCTION PROJECTS IN INDIA
IRJET, 2022
This study focuses on identifying and ranking the numerous elements that contribute to time and expense overruns in building projects. The main goal of this thesis was to use the literature to determine the numerous elements that cause time and expense overruns in construction projects and to create a questionnaire based on these factors. The detected criteria are listed in this questionnaire, along with a likert scale to indicate their importance. The survey was sent to several project stakeholders, including engineers, contractors, project managers, builders, and supervisors, who were asked to mark the criteria on the scale according to their comprehension. Relative Important Index analysis is used to determine the components and their effects on time and cost overrun. Data was gathered by using a Google form to conduct a survey; responses from experienced and highly qualified individuals were gathered to determine the importance of the supplied parameters using the Likert scale. The criteria were rated according to their impact on cost and time after thorough analysis of the data gathered from the respondents.

Advances in Technology
The time overrun in construction projects is a common issue around the world and no exception in Sri Lankan construction industry. The aims are to identify the causes and their significance to the project time overrun as well as to provide suggestions for those identified causes. Totally 39 significant factors were identified as relevant to Sri Lankan construction industry through a literature survey. Then a quantitative questionnaire approach was conducted to identify the significance of factors from industry professionals (civil engineers, quantity surveyors, technical officers, supervisors & directors, and the persons with minimum qualification and experience in the construction industry) working as stakeholders such as clients, consultants, and contractors without considering the project type. The previously identified 39 factors were found to be applicable to the Sri Lankan construction industry with survey results. Through the survey, 33 responses were collected and analyzed b...
Time overruns and Cost overruns has been a major issue in many Indian construction projects. The successful execution of construction projects and keeping them within prescribed schedule and cost is very important for effective time performance and cost performance. This research work is carried out on studying significant factors causing Time overruns and Cost overruns in Indian construction projects. A valid questionnaire for the survey was developed based on factors for time overruns and factors for cost overruns identified from literature review. These factors are grouped into 12 categories for time overruns and 8 categories for cost overruns and distributed to Contractors, Consultants, and Owners of Indian construction Industry. The data from the questionnaire was analyzed statistically. Relative important index method was used to found out the most significant factors affecting Time and Cost overruns. The result accomplished from the survey revealed that the major cause for time overruns are material market rate, contract modification, and high level of quality requirement and the major cause for cost overruns are high transportation cost, change in material specification, and escalation of materials price. The study findings highlight the significant factors and some recommendations are given to control time and cost overruns in Indian construction Industry.

The Construction industry is one of the key economic industry in India and is the main motivating force in Indian national economy. But, it suffers from a number of problems that affect time, cost and quality performances. Successful management of construction projects is based on three major factors i.e. time, cost and quality. The successful completion of construction projects within the specified time has become the most valuable and challenging task for the Managers, Architects, Engineers and Contractors. How to achieve this task is a problem, which should be solved. The overall objective of this study is to identify the factors responsible for overruns in time and cost of the construction project and suggest the suitable remedial solutions.
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.
A Study of Factors Caused for Time & Cost Overruns in Construction Project & their Remedial Measures

Significance and Analysis of Time and Cost Overrun in the Construction Industry of Mumbai
IJRASET, 2021
The occurrence of time and cost overrun has become quite significant in a majority of construction projects in India, which is negatively affecting the GDP and potential development of nation. As per the statistics of project cost and duration in March 2012, 179 projects out of 555 projects of worth 150 Crore INR have been facing cost and time overrun and others are at the very high risk, with the total construction cost overrun of 1.23 Lakh Crore INR. (Times, 2013) The time and cost overrun of the construction projects results in overextension of the time and finance of the client which may lead to entire failure of the project, unfinished project, abandoned project or reduction in the performance standards of the project. This condition depicts the requirement of the study and analysis of the causes or risk factors for time and cost overrun, and solutions and strategies for mitigation of cost and time overrun. The present research involves the study and analysis of the various risk factors related to time and cost overrun; assessment of the overruns in the construction projects of Mumbai, India and other parts of the world; identification and analysis of the leading causes for time and cost overrun in the construction projects of Mumbai; identification of potential solutions; and preparation of an effective mitigation model for overruns in construction projects of Mumbai.
