FASL FACTOR ANALYSIS OF TIME AND COST OVERRUNS IN CONSTRUCTION OF IRRIGATION PROJECTS.

DEERAVATH, VINOD KUMAR NAYAK; N., SURESH KUMAR

Most construction projects in Telangana, India, are subject to time and cost overruns. This phenomenon may adversely affect the progress of the construction industry in Telangana, India, and potentially lead to the collapse of many construction organizations. This study focuses on identifying and evaluating the factors contributing to time and cost overruns in construction projects in Telangana, India, specifically in the construction of irrigation projects. To achieve the objectives of this study, initial questionnaire surveys were conducted, followed by factor analysis of time and cost overruns. Approximately ten projects were visited, and data were collected over a span of twenty-two months. The factors causing time and cost overruns in irrigation construction projects in Telangana were categorized into four major groups: manpower-related, machinery-related, equipment-related, and financial-related. These factors were analyzed using Statistical Package for Social Sciences (SPSS) software for factor analysis. Factor analysis was conducted using two distinct approaches: Exploratory Factor Analysis which explores underlying structures without prior hypotheses and Confirmatory Factor Analysis (CFA) which tests a pre-specified model, requiring prior knowledge. EFA and CFA are complementary techniques for understanding the underlying structure of a set of variables. CFA can refine the factor structure suggested by EFA. The combined results from these analyses contribute to the development of reliable and valid measurement scales.
