ForewordThe Eleventh Plan envisages an investment of Rs. 3,14,152 crore (US$ 80 billion) in the road sector, of which Rs. 1,06,792 crore (US$ 27 billion) is expected from Public Private Partnerships (PPPs) that would serve as the vehicle for attracting private capital in public infrastructure projects aimed at improving efficiencies and reducing costs. Besides the Central Government, several states are pursuing PPPs for developing their respective highways. A well-defined policy and regulatory framework consistent with international best practices has since been adopted for application to PPP projects in the highway sector. This is reflected in the standardised documents for bidding and award of projects. In particular, the Government of India has adopted a Model Concession Agreement (MCA) for PPPs in National Highways. On similar lines, the Planning Commission has published an MCA for State Highways. These MCAs follow the Design, Build, Finance and Operate (DBFO) approach that requires the Concessionaire to bear the responsibility for detailed design. However, the responsibility for providing safe and reliable roads ultimately rests with the Government and the MCA, therefore, mandates a Manual of Standards and Specifications that the concessionaire must conform to. Consistent with the DBFO approach, only the core requirements of design, construction, operation and maintenance of the project highway are to be specified. In sum, the framework should focus on the 'what' rather than the 'how' in relation to the delivery of services by the concessionaire. This would enable cost efficiencies to occur because the shift to output-based specifications would provide the private sector with a greater opportunity to add value by innovating and optimising designs in a way normally denied to it under conventional input-based procurement specifications.

MANUAL OF SPECIFICATIONS AND STANDARDS

For evolving standards conforming to the DBFO approach, the Planning Commission asked the Indian Roads Congress (IRC), the apex institution of highway engineers in India, to develop this Manual of Standards and Specifications for fourlane highways. The Manual has been evolved after extensive consultations with experts and stakeholders. Following the conventions of IRC, deliberations on this Manual were undertaken in several workshops where experts drawn from the Central and State governments, private sector entities, academia and research organisations participated. A Round Table was also organised at the Planning Commission where representatives of Central and State Governments participated, besides several other stakeholders and experts. The present document represents a broad consensus arising out of the aforesaid consultations spanning over four years. This has since been approved by the Council of the Indian Road Congress. The Manual would, by reference, form an integral part of the MCA and would be binding on the concessionaire. Its provisions would be enforceable and any breach would expose the concessionaire to penalties, including termination of the concession. The Manual is to be used in relation to Schedule D of the MCA. Besides integrating this Manual into the concession agreement, the said schedule permits deviations from the Manual to address project-specific requirements. However, all such deviations would need to be stated precisely with a view to enabling bidders to assess their costs with some degree of accuracy. Since the concessionaire would be contractually bound by the provisions of the Manual, care has been taken to ensure that it is consistent with the provisions of the MCA. This Manual and the MCA together should facilitate the respective Governments in taking up a large programme for development of safe and reliable roads through PPPs, with least cost to the

users and to the public exchequer. The Manual reflects a delicate balance that was arrived at after extensive deliberations with a view to ensuring development of quality roads and at the same time improving their financial viability by optimizing on costs and obligations. Modifications, if any, should be made by the executing agencies with due regard to their legal, financial and technical implications on the underlying contractual framework. The office-bearers of IRC, especially its President and Secretary General are to be complimented for the
