IRC Code: Manual on Economic Evaluation of Highway Projects in India (IRC:SP:30-2009)

‍

Highways play a pivotal role in India's economic development, connecting cities, facilitating trade, and ensuring smooth transit for people and goods. Among the most important guidelines for planning and executing highway projects is the IRC:SP:30-2009, titled the Manual on Economic Evaluation of Highway Projects in India (Second Revision). This document, developed by the Indian Roads Congress, provides comprehensive methodologies for the economic analysis of highway projects, ensuring cost-effectiveness and long-term benefits.

Understanding the IRC:SP:30-2009 Code

‍

First published in 1984, the IRC:SP:30 has undergone several revisions to align with changing economic conditions and advancements in vehicle and road technology. The 2009 version integrates updated Vehicle Operating Cost (VOC) equations, reflecting the evolving standards of road infrastructure and transportation in India. This manual serves as an indispensable tool for highway engineers, policymakers, and consultants, enabling informed decision-making for medium to large-scale highway projects.

Key Features of IRC:SP:30-2009

‍

1. Economic Analysis Framework:
   • Focuses on Benefit-Cost (B/C) ratio analysis to quantify the monetary benefits and justify investments in road infrastructure.
   • Prioritizes evaluating both direct and indirect benefits like reduced VOC, travel time savings, and accident cost reduction.
2. Comprehensive Data:
   • The manual includes VOC equations updated based on 2001 studies conducted by the Central Road Research Institute (CRRI).
   • Detailed tables and formulas for assessing transportation costs, including construction, maintenance, and user costs.
3. Environmental and Social Impacts:
   • Highlights qualitative factors like environmental impacts, improved connectivity, and socio-economic development.
   • Encourages planners to incorporate sustainability and community welfare in project evaluations.
4. Stages of Economic Evaluation:
   • Guidance on project preparation, data collection, cost-benefit analysis, and final appraisal for informed decision-making.
   • Provides a step-by-step approach for comparing alternative highway project designs, such as flexible versus rigid pavements.
