To bid for government construction tenders in Bihar – roads, buildings, rural works – a contractor must first be registered with the department that issues the work. The three departments most contractors start with are the Building Construction Department (BCD), the Road Construction Department (RCD) and the Rural Works Department (RWD). This guide explains who can register, what documents you need and how the process works.
Which department do you need?
| Department | Type of work |
|---|---|
| BCD – Building Construction Department | Government buildings, offices, hospitals, schools and other building works |
| RCD – Road Construction Department | State highways, major district roads and bridges |
| RWD – Rural Works Department | Rural roads and connectivity works, including schemes like PMGSY |
Other departments such as Water Resources (WRD), Public Health Engineering (PHED) and bodies like Beltron have their own registration. Many contractors register with more than one department to widen the tenders they can bid for.
Who can apply?
- Sole proprietors
- Partnership firms and LLPs
- Private limited companies
- Unemployed engineers (degree / diploma holders), for whom departments usually offer special provisions
Registration classes
Contractors are registered in classes. Each class sets the maximum tender value you can bid for. Higher classes require more experience, a larger turnover, your own machinery and qualified engineers on your staff.
As an example, the RWD classes we commonly handle are:
| RWD class | Tender limit |
|---|---|
| Class-1 | No upper limit |
| Class-2 | Up to ₹3.5 crore |
| Class-3 | Up to ₹70 lakh |
Class limits, eligibility and government fees are revised by departments from time to time. Always check the current notification before you apply. We confirm the latest figures for every client.

- Missing the renewal date and losing eligibility for ongoing tenders
Frequently asked questions
Can I register with more than one department?
Yes. Registrations are department-wise. Many contractors hold BCD, RCD and RWD registrations together.
Do I need GST registration?
Yes. A valid GSTIN is required for registration and for billing government works. We can help with GST registration if you don’t have one yet.
Is a digital signature mandatory?
Yes. A Class III DSC is needed to apply online and to take part in e-tenders.
Should I register as a proprietor or a company?
For larger tenders and long-term growth, many contractors prefer a private limited company because of limited liability and better credibility with banks for solvency and guarantees.
