NHAI Schedule of Rates
About National Highways Authority of India
NHAI is India's largest highway-construction agency, executing over 1.3 lakh km of national highways. Its EPC and HAM tender packages use MoRTH SDB rate analysis with project-specific BoQs reflecting alignment, terrain, structures and traffic. The Revised Standard EPC Agreement (April 2022) standardises contract clauses, schedules and rate-revision formulas across NHAI projects.
Frequently Asked Questions
Where can I find NHAI's Schedule of Rates?
NHAI does not publish a standalone SOR. Use the MoRTH Standard Data Book (SDB) for rate analysis and the project-specific BoQ inside each NHAI tender RFP for actual rates. The Revised Standard EPC Agreement (2022) contains the contractual rate framework.
What is the difference between NHAI EPC, HAM and BOT?
EPC: Engineering, Procurement, Construction — government pays as per progress. HAM: Hybrid Annuity Model — 40% from government during construction, 60% as annuity. BOT: Build, Operate, Transfer — concessionaire collects toll. Rate analysis differs per model — EPC uses item rates, HAM/BOT use lump-sum project rates.
Where do I find NHAI's similar-work definition?
The Revised Standard EPC Agreement (2022, available here) and subsequent MoRTH circulars define 'similar work' eligibility for bid qualification — typically 35% of project value executed in similar terrain/structure category.
Are NHAI tender BoQ rates publicly available?
Tender RFPs are public during the bid window via etenders.gov.in/eprocure portal. Once tenders close, the awarded BoQ becomes part of the project record. Historical NHAI contract rates can be inferred from awarded contract values divided by quantity, published in NHAI's annual reports.
Does NHIDCL use NHAI's framework?
NHIDCL (for NE states and J&K projects) follows the same MoRTH SDB rate-analysis basis with NHIDCL-specific tender packages. Both NHAI and NHIDCL operate under MoRTH oversight.
