A responsive bid package contains every form, security, certification and acknowledgement the solicitation requires, signed, complete and delivered on time. A bid bond is the bid security that guarantees you will sign the contract if you win. Use the checklist below on every bid; most rejected bids are lost on paperwork, not price.
This checklist works for county, school, state and private invitations to bid. Always replace generic items with the exact requirements of the instructions to bidders.
What is a bid bond and why do owners require one?
Bid security protects the owner if the low bidder walks away. A bid bond is issued by a surety on your behalf; if you refuse to sign the contract or furnish required bonds, the surety may pay the owner the difference between your bid and the next acceptable bid, up to the bond amount. Some owners accept a certified check or cashier's check instead. For federal construction, bonding rules follow the Miller Act and the Federal Acquisition Regulation, summarized in FAR Subpart 28.1; states have their own "little Miller Act" statutes. The amount, form and wording are set by the solicitation. Contractors who need bonding capacity can start with the SBA surety bond program and a bonding agent.
What is on a complete bid package checklist?
1. Before you price
- Download the full package: notice, instructions to bidders, bid form, conditions, specifications, drawings and every addendum.
- Log the bid date and time, time zone, delivery method and question deadline.
- Confirm license class, registration, prequalification and bonding capacity.
- Note whether a pre-bid meeting or site visit is mandatory.
2. While you price
- Complete a takeoff by CSI division, then price labor, material, equipment and subcontract scopes.
- Send scope sheets to subcontractors and suppliers and collect written quotes.
- Price all alternates, unit prices and allowances separately as the bid form lists them.
- Check wage requirements; apply the stated prevailing-wage determination where required.
- Add general conditions, bonds, insurance, taxes, overhead, profit and contingency.
3. Bid form and attachments
- Every line priced; no blank spaces; no changes to the form.
- Base bid written in numbers and words where required, and both agree.
- All addenda acknowledged by number and date.
- Signature by an authorized officer; corporate seal or notarization if the form requires it.
- Bid bond, certified check or other security in the exact amount and form.
4. Supporting documents
- Contractor license and registration numbers; business license and tax identification.
- Insurance certificates with the limits and endorsements stated.
- Required affidavits: non-collusion, conflict of interest, debarment, drug-free workplace, E-Verify, and similar.
- Subcontractor and supplier lists, small or local business participation forms, and references.
- Schedule, staffing or approach narrative when requested.
5. Final check and submission
- Have a second person verify math, the base bid and the forms against the checklist.
- Check for addenda again on the morning of bid day and one hour before the deadline.
- Submit electronically early and save the receipt, or deliver sealed bids to the exact address and room and ask for a time-stamped receipt.
- Keep a complete copy of what you submitted and your bid backup.
What are the most common reasons a bid is rejected?
- Late submission, even by minutes.
- Missing or insufficient bid security.
- Unacknowledged addendum.
- Unsigned or altered bid form.
- Unpriced items or a mathematical conflict between words and numbers.
- Missing license, insurance or required certification.
How can a checklist be part of your estimating process?
Store a standard checklist in your estimating system, copy it for each bid, and assign owners with times, for example subcontractor quotes due 48 hours before bid, internal review 24 hours before, submission 2 hours before. Bid Sharp supports this with pre-bid estimating support and bid and proposal support, from takeoff to a bid-ready package your team reviews and signs.

Frequently asked questions
What is a bid bond?
+
A bid bond is a form of bid security issued by a surety that guarantees the bidder will sign the contract and provide required performance and payment bonds if awarded. If the bidder refuses, the surety may owe the owner the difference up to the bond amount.
How much is a typical bid bond?
+
The solicitation sets the amount, often as a percentage of the bid price; five percent is common, but some owners use a different amount. Follow the bid documents exactly.
What is the difference between a bid bond and a performance bond?
+
A bid bond protects the owner during bidding. A performance bond guarantees completion of the work after award, and a payment bond protects subcontractors and suppliers.
