projects in the international context EFFECTS OF CONSTRUCTION COST AND CHANGE ORDERS ON CONSTRUCTION TIME FOR INDUSTRIAL AND COMMERCIAL PROJECTS IN INDIA

Studies indicate that there is a relationship between project cost and construction time within construction projects. The purpose of this study is to validate a time-cost relationship model developed by Bromilow et al. (1980) with reference to both commercial and industrial construction projects in India. The model was extended to include change orders and construction procurement methods to determine whether these variables would also have an effect on project duration. Data related to 20 industrial and 27 commercial projects completed in India within last five years was obtained for the study. SPSS ® software was the primary data analysis tool. The statistical technique used for the analysis was a multiple linear regression. The results indicate that Bromilow et al.’s (1980) model holds good for the Indian construction industry at the level of significance (p-value) of < 0.0001. The results also indicate that there is a statistically significant relationship between construction time and actual construction cost as well as between construction time and number of change orders, both in commercial and industrial sectors. Furthermore, the results indicate that, in India, the time taken for construction of commercial projects is significantly higher than that for industrial projects
