About Performance Bank Guarantee in Indian Government Contracts

What is a Performance Bank Guarantee (PBG)?

A Performance Bank Guarantee (PBG) — also called Security Deposit or Contract Performance Guarantee — is a financial guarantee submitted by the successful bidder after being awarded a government contract. It assures the tendering authority that the contractor will execute the work as per the contract terms, quality standards, and timelines. In Indian government procurement under GFR 2017 and CPWD norms, PBG is typically 5–10% of the contract value.

What is the Defect Liability Period (DLP)?

The Defect Liability Period (DLP) starts after the project is completed and handed over. During this period, the contractor is responsible for rectifying any defects in the work at no extra cost. DLP is typically 12–24 months as per CPWD/PWD norms. The PBG must remain valid through the entire DLP — the tendering authority can invoke the BG if the contractor fails to fix defects. Always get your bank to extend the BG before DLP expires.

How to Calculate PBG Amount

PBG Amount = Contract Value × PBG %
Example: For a ₹5 crore contract at 5% PBG → ₹25,00,000 performance guarantee required.
The BG must remain valid for the full contract period plus the DLP plus an additional 30–60 day buffer for final inspection and return.

Staged PBG Release

Many government contracts allow staged release of the PBG: typically 50% is released after satisfactory completion of the work, and the remaining 50% is held through the DLP. This reduces the bank charges burden on the contractor. Check your specific contract clauses for staged release eligibility — it can significantly reduce your BG cost burden for long-duration contracts.

Important: Never let your PBG lapse while the contract or DLP is active. A lapsed BG can be invoked by the department and is very difficult to contest. Set calendar reminders 60 days before BG expiry to arrange renewal.
