What is a bid form in construction?
A bid form is the document the owner provides for bidders to submit their price. It fixes the format for the base bid, alternates, unit prices, addenda acknowledgments, and signatures so bids can be compared fairly. On public work, a bid that does not follow the form can be rejected as nonresponsive, even at the lowest price.
A bid form (also called a proposal form) is the standard page or set of pages in the bid documents where each bidder writes its price and commitments. The owner writes the form; the bidder fills it in exactly as instructed. On public work, a bid that does not follow the form can be rejected as nonresponsive, even if it is the lowest price.
Federal construction solicitations often use Standard Form 1442, Solicitation, Offer, and Award (Construction, Alteration, or Repair), published by GSA under FAR 53.236-1. State agencies, cities, school districts, and private owners use their own forms.
What is on a typical bid form
- Base bid. The lump sum price for the work in the contract documents, often in words and figures.
- Alternates. Add or deduct prices for options the owner may choose, such as an upgraded roof or a deleted canopy. See alternate bid.
- Unit prices. Rates for quantities that may change, such as rock excavation per cubic yard.
- Allowances. Amounts the owner set, which bidders include as stated. See allowance.
- Addenda acknowledgment. A line for every addendum issued.
- Schedule. A required completion time, or a place for the bidder to state one.
- Subcontractor listing. Some public owners require major subs to be named.
- Signatures and attachments. Authorized signer, license number, bid bond, and required affidavits or certifications.
How a bid form works on bid day
An estimator has a school renovation due at 2:00 p.m. The bid form asks for a base bid, three alternates, two unit prices, and acknowledgment of four addenda. The base number is ready by 11:00, but sub quotes keep coming. The team fills in everything except the base bid and alternates in advance, checks the addenda against the list on the owner's website, and has the bond and signed forms ready. At 1:35 they enter the final numbers in words and figures, a second person reads them back against the spreadsheet, and the runner leaves for the bid desk.
Common catches on that read-back: the words and figures do not match, Alternate 2 was entered as an add when it is a deduct, or the fourth addendum, issued two days ago, is not acknowledged.
| Item | Check |
|---|---|
| Base bid in words and figures | Match each other and the summary sheet |
| Alternates | Add or deduct marked correctly |
| Unit prices | Units match the form, not the estimate |
| Addenda | Every addendum number listed |
| Signature | Authorized officer, dated |
| Bid security | Correct amount and form, signed by surety |
Common mistakes
- Changing the form, adding qualifications, or attaching exclusions when the instructions forbid it. On public jobs that can make the bid nonresponsive.
- Missing an addendum acknowledgment.
- Unsigned or signed by someone without authority.
- Words and figures that disagree. Many forms say words govern, which can cost real money.
- Late delivery. A bid that arrives a minute after the deadline is commonly rejected.

Frequently asked questions
Can I add exclusions to a bid form?
On private work, sometimes, if the instructions allow. On public sealed bids, adding qualifications usually risks rejection as nonresponsive. Ask questions before bid day through the RFI process instead.
What form is used for federal construction bids?
Many federal construction solicitations use Standard Form 1442, Solicitation, Offer, and Award (Construction, Alteration, or Repair). Check the specific solicitation.
What happens if the words and figures on a bid form do not match?
It depends on the bid documents. Many say the written words govern. Some owners may reject the bid. Check every number twice before submitting.
Do I have to acknowledge every addendum?
Usually yes. The bid form typically has a place to list them, and missing one can make the bid nonresponsive on public work.
