Time & Cost Overrun Analysis of Highway Projects

The study presents an insight into the present scenario on Indian highways including cross continental comparison with the neighbouring China as well as developed nations such as USA and Europe. The poor quality of road infrastructure coupled with heavy congestion on important national highways has led to initiation of National Highway Development Project (NHDP) was discussed in detail in the sub section background of study. The wide prevalence of delays in the implementation of highway projects under NHDP has necessitated the present study on time and cost overruns. Regression analysis was carried out on the ongoing highway projects using SPSS computer program and mathematical equations were derived between various project parameters to portray the behavior of time and cost overruns. Delay Index model incorporating the various causes of delay was evolved for estimation of time overruns and for predicting the future outcomes. Certain innovative suggestions such as beneficiary participation and auctioning of highway projects were aired for the sound implementation of NHDP. Strategies for future implementation such as project packaging, appropriate mix of BOT were also deliberated.
