One Bid per Bidder - IRC SP 124 Key Points

Clause 5.1:

• Each bidder must submit only one bid for the works.
• Multiple bids from the same bidder lead to disqualification of all such bids.

Bid Capacity Formula (Clause 2.5)

[ \text{Available Bid Capacity} = (A \times N \times 2.5) - B ]

Where:

• A = Maximum value of civil engineering works executed in any one year during the last 3 years (adjusted for escalation to current financial year).
• N = Number of years prescribed for completion of the works.
• B = Value of existing commitments and ongoing works during the next N years (also escalated).

Additional Qualification Criteria (Clause 4.5)

• Bidders can be disqualified for:
  • Misleading or false information in submitted documents.
  • Poor past performance (abandonment, delays, litigation, financial failures, debarment).

Summary

• One bid per bidder ensures fairness.
• Bid capacity formula helps assess bidder’s financial and technical ability.
• Strict disqualification criteria maintain integrity of the bidding process.
