Contractor Registration in Bihar — RWD and BCD Classes, Fees, Validity and the eproc2 Enrolment

Quick answer: Bihar's Rural Works Department and Building Construction Department register contractors department-wise in three classes: Class 1 for tenders of any value at a fee of ₹2,00,000, Class 2 up to ₹3.5 crore at ₹1,00,000, and Class 3 up to ₹70 lakh at ₹25,000 — paid in one instalment, valid five years, renewable at the same fee if applied a month before expiry, and upgradable by paying the difference. RWD applies online at contractor.rwdbihar.gov.in on PAN and Aadhaar authentication for individuals, firms, companies, JVs and a separate unemployed-engineer category; BCD takes the fee by demand draft to the Under Secretary, BCD, Patna. Bidding then needs a separate annual enrolment on eproc2.bihar.gov.in, a Class 3 DSC and a ₹590 processing fee per tender. We file the class application, assemble the solvency and experience proof and set the renewal clock.

Classes, limits and fees (RWD Contractor Registration Rules, as revised; BCD mirrors the same scale)

• Fee paid in full in one go (no part payment); validity 5 years; renewal at the same fee, applied for one month before expiry with a one-month grace period in which tendering continues
• Upgrade to a higher class by paying the difference in fee once the eligibility (turnover, experience, machinery, engineers) is met
• Each department registers separately — an RWD registration does not qualify you for BCD or RCD tenders
• Portals: RWD at contractor.rwdbihar.gov.in (individual, proprietorship, partnership, company, unemployed engineers, JV — PAN and Aadhaar authentication, then departmental verification); BCD through the department's online registration form, fee by demand draft payable to the Under Secretary, BCD, at Patna

The fee and limit scale above is as published by the departments and reproduced in their application guidance; the dated rule text (RWD Rules 2007 as amended) is confirmed with the division office before payment. RCD's scale and any 2024–26 amendment are checked at filing — figures circulating online for RCD with a "Class IV" or ₹1 crore limits do not match the departments' published scale.
