What Bid Security Is
Bid security is a financial assurance requested in some solicitations to support the bidder's commitment to the submitted bid. It may be required by public owners, private owners, or general contractors depending on the project and contract structure.
The bid documents should state:
- Whether bid security is required
- Accepted form
- Amount or calculation method
- Required obligee or payee
- Submission deadline
- Delivery method
- Signature or seal requirements
- Return process
- Conditions tied to withdrawal, refusal to execute, or award
Do not assume one owner's process applies to another bid.
Common Forms Of Bid Security
Accepted forms vary by solicitation. Common examples include:
- Bid bond
- Cashier's check
- Certified check
- Letter of credit
- Cash deposit
Some solicitations accept only one form. Others provide choices. The bid instructions control.
Bid Bond Review
When a bid bond is required or allowed, coordinate early with the surety.
Check:
- Correct bidder legal name
- Correct owner or obligee
- Project name and number
- Bid date
- Bond amount or calculation
- Authorized signatures
- Seal or notarization requirements where applicable
- Electronic or original submission rules
- Addenda or bid form references
Keep the final bond package with the bid submission checklist.
Check Or Deposit Review
If the solicitation allows a cashier's check, certified check, or deposit, confirm the exact payee, amount, delivery method, and return process.
Track:
- Who requested the check
- Who has custody before submission
- Delivery method
- Receipt or confirmation
- Return timing
- Accounting owner
Physical documents need clear ownership so they are not missed on bid day.
