Construction Bid Withdrawal and Error Correction: Know Your Rights

Bid errors happen. Despite best efforts, sometimes a significant mistake makes it into a submitted bid. Understanding your rights and procedures for bid withdrawal or correction can save your company from disastrous financial consequences. Here's what every contractor needs to know.

Understanding Bid Errors

Types of Bid Errors

Clerical Errors

  • Math mistakes
  • Transposition errors
  • Decimal placement
  • Extension miscalculations

Judgment Errors

  • Underestimating quantities
  • Misinterpreting scope
  • Pricing decisions
  • Production assumptions

Legal Distinction Clerical errors often allow relief. Judgment errors typically don't. The distinction matters significantly in determining your options.

Common Error Examples

| Error Type | Example | Relief Possible? | |------------|---------|------------------| | Clerical | Typed $50,000 instead of $500,000 | Usually yes | | Clerical | Forgot to add subcontractor quote | Usually yes | | Clerical | Double-counted an item | Usually yes | | Judgment | Underestimated labor hours | Typically no | | Judgment | Missed scope in specifications | Typically no | | Judgment | Market pricing decision | Typically no |

Legal Framework

Public Contracts

Bid Relief Principles Most jurisdictions allow bid relief when:

  • Error was clerical, not judgment
  • Error was material (significant impact)
  • Bidder exercised reasonable care
  • Owner not seriously prejudiced

State Variations Rules vary by state. Some are more liberal with relief, others more restrictive. Know your jurisdiction's approach.

Private Contracts

More Flexibility

  • Contract law governs
  • Owner discretion larger
  • Negotiation possible
  • Relationship factors

Less Predictable

  • No standardized rules
  • Owner may or may not grant relief
  • Business considerations dominate

Bid Withdrawal Procedures

Before Bid Opening

Generally Allowed

  • Right to withdraw usually exists
  • Follow specified procedures
  • Written notice recommended
  • Document the withdrawal

Procedure

  1. Review bid documents for withdrawal rules
  2. Prepare written withdrawal notice
  3. Submit before opening time
  4. Confirm receipt

After Bid Opening

More Restricted

  • Must meet legal standards
  • Prompt notice required
  • Documentation critical
  • Owner decision process

Required Elements

  • Immediate notification
  • Specific error identification
  • Supporting documentation
  • Relief request

Error Discovery and Response

Discovering Errors

Common Discovery Points

  • Post-opening price comparison
  • Internal review after submission
  • Subcontractor notification
  • Client questions about pricing

Warning Signs

  • Your price significantly lower than others
  • Subcontractor says "that's not my number"
  • Internal check reveals discrepancy
  • Missing items identified

Immediate Actions

Upon Discovery

  1. Stop and verify the error
  2. Document exactly what happened
  3. Calculate the impact
  4. Prepare supporting materials

Notification

  • Contact owner immediately
  • Written notice same day if possible
  • Preserve all evidence
  • Be honest and specific

Documentation Requirements

What to Document

Error Evidence

  • Work papers showing error
  • Correct calculations
  • Before/after comparison
  • Source documents

Timing Evidence

  • When error was made
  • When discovered
  • Notification timeline
  • Communication records

Maintaining Records

Best Practice

  • Keep all bid work papers
  • Preserve in organized fashion
  • Date and label materials
  • Retain for potential disputes

Specific Items

  • Subcontractor quotes
  • Takeoff sheets
  • Pricing spreadsheets
  • Calculation records

Relief Standards

Clerical Error Relief

Typical Requirements

  1. Error was computational/clerical
  2. Error can be proven clearly
  3. Enforcement would be unconscionable
  4. Owner not materially prejudiced
  5. Prompt notice given

Supporting Your Claim

  • Clear documentation of error
  • Calculation showing correct figure
  • Evidence of when error occurred
  • Demonstration of error's nature

Material Prejudice

Owner's Position

  • Reliance on your bid
  • Award decisions made
  • Other bidders released
  • Project timeline impact

Balancing Test Courts balance bidder's hardship against owner's prejudice. Significant bidder harm with minimal owner impact favors relief.

Practical Scenarios

Scenario 1: Major Math Error

Situation: Bid extension error results in price $200,000 below intended

Response

  1. Notify owner immediately after discovery
  2. Provide calculation showing error
  3. Request withdrawal
  4. Document everything

Likely Outcome: Relief often granted for clear math errors with proper documentation and prompt notice

Scenario 2: Missing Subcontractor

Situation: Major subcontractor quote omitted from bid

Response

  1. Document which quote was missing
  2. Show work papers without that quote
  3. Provide correct total with quote included
  4. Request relief

Likely Outcome: Can be granted if clearly clerical—quote existed, simply wasn't included

Scenario 3: Scope Misunderstanding

Situation: Misinterpreted specification, priced cheaper alternative

Response

  1. This is typically judgment, not clerical
  2. Relief less likely
  3. Negotiation may be possible
  4. May need to perform as bid

Likely Outcome: Relief difficult—interpreting specs is judgment, not clerical

Conclusion

Bid errors are serious but not always fatal. Understanding the legal framework, acting promptly, and documenting thoroughly gives you the best chance at relief when errors occur.

Prevention is better than cure. Build review processes that catch errors before submission. When errors do occur, respond immediately, document completely, and pursue appropriate relief.

Know that clerical errors typically offer more relief options than judgment errors. Be honest about the nature of the error and realistic about your options. And always maintain the documentation that supports your position.
