Time-Cost Relationship for Infrastructure Projects in India

摘要

Studies indicate that there is a relationship between project cost and construction time for different construction markets and construction sectors. The purpose of this study is to validate the time-cost relationship model developed by Bromilow et al in context with infrastructure (i.e. bridges and roads/ highways) projects in India. The model was extended to include change orders to determine whether this variable also has an effect on project duration. Data related to 50 infrastructure projects in India completed within last five years was obtained for the study. SPSS program was used for analysis of the data. The statistical technique used for the analysis was a multiple linear regression. The results indicate that Bromilow et al.'s model holds good for the Indian Construction Industry at the level of significance (p-value) of < 0.0001. The results indicate that there is a statistically significant relationship between construction time of infrastructure projects and their actual construction cost and number of change orders.
