A construction bid form is the owner's document, and you fill it in. You do not download a template and rewrite it. The form fixes how your price is stated, who signs and which addenda you acknowledge, and a bid that strays from it can be thrown out. Complete every line as printed, recompute every extension, list every addendum and sign with authority to bind the company. The rules cited below are federal sealed-bid examples, so read your owner's instructions too. For a layout of your own proposal, a later section links one.
Three things called a bid sheet
A bid sheet for construction can mean three different papers, and estimators say "bid form" for the same three. Mixing them up can send a sub's price sheet to an owner, or lead someone to treat the owner's form as optional.
Meaning | Written by | Filled in by | Job |
|---|---|---|---|
Owner's bid form, with its schedule of prices | The owner or design team | The bidder | Carries your offer on the owner's terms |
Subcontractor's bid sheet | The general contractor | The sub or supplier | Puts line prices in one layout so quotes compare |
Homeowner's comparison sheet | The homeowner or a template | The homeowner | Lines up quotes. It is not a bid |
A bid sheet usually travels inside the bid package, so read what a bid package contains before you price. Returned sheets still need bid leveling before you compare them, and bid, quote and proposal differences sorts the other documents. Only the first row is a document an owner can reject, so the rest of this page is about it.
Construction bid form: what the owner's form controls
The owner's form controls four things: how the price is stated, who may sign, which amendments you acknowledge, and where and when the bid arrives. Federal work shows the pattern. The federal construction form, Standard Form 1442, says its offer section must be fully completed by the bidder. The table picks out the blocks a bidder reads or completes.
Block | What you enter | Slip to avoid |
|---|---|---|
13a | Nothing. Read the place, hour, local time and envelope marking | Wrong place, late hour or an unmarked envelope |
13b | Nothing. Read whether a bid guarantee is required | Missing the guarantee, or mixing it up with the bonds in 12a and 18 |
13d and 17 | Calendar days your offer stays open, at or above the minimum | Fewer days. The form says that offer will be rejected |
Amounts box under 17 | The prices and total the form asks for, tied to your schedule | A total that does not match the extensions |
19 | The number and date of each amendment | Listing fewer than the owner issued |
20a to 20c | The authorized signer's name and title, the signature and the date | A signer with no authority, or no date |
The acceptance period is plain arithmetic. Say bids are due March 4 and block 13d prints a 60-day minimum. Sixty calendar days after March 4, 2027 is May 3. An entry of 45 days runs only to April 18, which is 15 days short.
State and local forms look different. Some owners take bids on an online screen, and some forms add a license number, a notarized signature or the price in words as well as figures. The instructions to bidders say which. Some firms hand the forms pack to an outside desk, and what an outside desk takes over shows what moves and what stays with you.
How to fill in the schedule of prices, line by line
A unit-price form carries a schedule of prices. The owner prints the item, description, unit and quantity, and you enter the unit price and extend it. A form can also ask for a lump-sum base bid, alternates or a mix, as FAR 52.214-18(b) allows for federal bids. Then write one figure per base bid and per alternate, the way the owner prints it. Where the prices come from is a separate job, covered in how a public bid is priced.
All dollar figures in this example are illustrative. They are round numbers chosen to keep the arithmetic easy to follow, not market prices, wage rates or quotes, and your own numbers will differ. The schedule below has six made-up lines.
Item | Description | Unit | Owner's quantity | Your unit price (illustrative) | Extension (illustrative) |
|---|---|---|---|---|---|
1 | Mobilization | LS | 1 | $10,000.00 | $10,000.00 |
2 | Excavation | CY | 1,850 | $4.00 | $7,400.00 |
3 | Aggregate base | CY | 640 | $12.50 | $8,000.00 |
4 | Curb and gutter | LF | 2,200 | $7.50 | $16,500.00 |
5 | Asphalt paving | TON | 910 | $20.00 | $18,200.00 |
6 | Pavement striping | LF | 3,400 | $0.50 | $1,700.00 |
Total of extensions | $61,800.00 |
Work the illustrative schedule in this order.
Price every line. Under the same provision, a federal construction bid that skips an item is disqualified when bids are required on all items. If not all are required, you write "no bid" in the blank.
Leave the owner's quantities alone. If one looks wrong, ask in writing before the question deadline and price the printed one. Price every alternate the form prints, unless it lets you mark "no bid", and offer none of your own, since the same provision considers an alternate bid only if the solicitation authorizes it.
Extend, then add. Item 4 is 2,200 LF x $7.50 = $16,500.00. The column is $10,000.00 + $7,400.00 + $8,000.00 + $16,500.00 + $18,200.00 + $1,700.00 = $61,800.00. A second person recomputes every line.
Keep changes clean. The same provision makes the signer initial any erasure or change. Reprint the page instead.
Check each printed quantity against your own takeoff and price every line, since a blank line can disqualify a bid. Takeoff Services LLC sells outsourced takeoffs and bid management. The takeoff can be counted and the forms pack assembled and checked against the owner's form by someone outside, and you still sign it.
Check the schedule against your estimate
Compare each extension with your estimate. FAR 14.404-2(g) lets an agency reject a bid with materially unbalanced line items. It points to FAR 15.404-1(g), which calls lines significantly over or understated unbalanced and names a separate mobilization line as a high-risk spot.
In the illustrative schedule, item 1 is 16.2 percent of the total ($10,000.00 / $61,800.00). Owners can slow the payment of a large mobilization line. Under Article 800-2 of the January 2024 NCDOT standard specifications, any mobilization amount above 5 percent of the total bid is paid on the last partial pay estimate. Here 5 percent of the total is $3,090.00, so $6,910.00 of item 1 would wait. Read how your owner pays it, and be ready to explain a share like this one.
When a figure on the form is wrong
Now a slip that is easy to make under deadline pressure. Say the extension for item 4 in the illustrative schedule is written as $1,650.00 instead of $16,500.00. The column adds to $46,950.00, which is $14,850.00 (24.0 percent) below the $61,800.00 you meant.
Which figure governs is the owner's call. FAR 14.407-2(a) names an obvious misplaced decimal point as an apparent clerical mistake that the contracting officer may correct before award, after the bidder verifies the bid it intended. On a paper bid, Article 103-2(A)(3) of the same NCDOT specifications lets the unit bid price govern, which restores item 4 to $16,500.00, and its electronic bids generate the totals. Other owners write the rule differently, so find the sentence in your instructions before bid day.
Relief after opening can be narrow. Article 103-3(A) of the same specifications lists what the department must find before it may let a bidder withdraw, including a clerical or mathematical mistake and not bad judgment, an error of at least 3 percent of the total bid, and notice within 48 hours after the opening.
Addenda, bid security and forms that ride with the bid
Every addendum changes the bid documents, so the form asks you to list each one. FAR 52.214-3 lets a federal bidder acknowledge an amendment by signing and returning it, by writing its number and date on the bid form, or by letter, and it must reach the owner by the deadline. The log itself belongs to the bid desk, and controlling addenda until the bid is sealed shows how to keep it. At the form, count: four addenda in the log and three lines used means one is missing.
A bid guarantee is a separate paper, often a bond. FAR 28.101-4 lists narrow federal waivers, such as a bond left unsigned on a signed offer or a misdated bond. Treat those as the owner's grace, not your plan.
Check these papers against the instructions to bidders, because owners differ:
Authority to sign. A Transportation Research Board legal reference updated in 2014 treats a bid with no corporate resolution authorizing the signer as a material defect the agency cannot waive, citing an Illinois decision. Attach a resolution or letter if asked.
Subcontractor list and certifications. Sign and date every affidavit the instructions name. The same reference says a missing subcontractor list cannot be waived where a statute requires one. It also lists a missing equipment list, experience description or financial statement among the irregularities agencies have had to weigh. It adds that an agency can usually waive a skipped pre-bid meeting unless the owner made attendance a stated requirement.
Wage rates. If the package attaches rates, price to the wage determination in the bid package and check whether the form asks you to acknowledge it.
Minor mistakes versus mistakes that end a bid
The owner decides what is minor, within the law that binds the owner. Federal sealed bidding gives a model. FAR 14.301 makes a bid eligible for award only if it complies with the invitation in all material respects. FAR 14.405 defines a minor informality as a matter of form and not substance, which the officer must either let you cure or waive, whichever favors the owner.
Slip | FAR citation (codified text) | Result |
|---|---|---|
Bid not signed | 14.405(c) | Minor only if other material shows intent to be bound, or the bid carries a typed or stamped signature you formally authorized before opening and proved |
Amendment not acknowledged | 14.405(d) | Minor only if the bid shows you received it, or the change is only a matter of form or has no or a negligible effect on price, quantity, quality or delivery |
Required line left blank | 52.214-18(c) | Disqualified when bids are required on all items |
Conditions added to the bid | 14.404-2(d) | Rejected when they change the requirements or limit your liability |
Required bid guarantee missing | 14.404-2(j) | Rejected, with the narrow exceptions in FAR 28.101-4 |
Materially unbalanced prices | 14.404-2(g) | May be rejected |
State and local owners do not copy these rules. The same reference gives the usual test: a defect forces rejection when it affects the bid amount and gives one bidder an advantage the others lack. It says an unsigned bid is normally a material defect, because the bidder could walk away without forfeiting its bond, and that most states require rejecting a late bid. It describes a Louisiana statute that bars waiving substantive requirements on the bid form, as of that 2014 text. The owner's instructions arrive with the posting, so know where public bids are posted before the clock starts.
Using your own form or cover letter
Use the owner's form whenever the package includes one. On federal sealed bids, a cover letter should carry only your name and a contact. FAR 14.301(c) counts a bidder's own form or letter only if the bidder accepts every term of the invitation, and FAR 14.404-2(d) rejects a bid with conditions that change the requirements or limit liability. Put exclusions and clarifications in written questions before the cutoff, and let the addendum answer for every bidder.
On private work the contractor's instructions control. Fill in a general contractor's sheet, and attach a proposal only if the contractor allows one. With no form supplied, a bid proposal template lays out your own.
A pre-submission check on the form, in order
Run the same six checks in the same order on every bid. A second person reads each line of the form aloud while you read the workbook.
Signer. Name and title are on the form, and the signer can bind the company. Every signature, date and initial block is filled, including later pages and the bond.
Schedule. Every line is priced, or marked "no bid" only where the form allows it. Each extension is recomputed, the total matches your estimate, every alternate and allowance the form prints is filled as the form directs, and none of your own is added.
Addenda. The number issued equals the number acknowledged, with matching numbers and dates, and you rechecked every posting for new ones.
Security. The guarantee has the right project, owner, form and amount, and your legal name matches the form.
Certifications. Every affidavit, participation form and subcontractor list the instructions name is complete, signed and dated.
Delivery. Place, method, copies, marking and the due time's time zone are right, with a buffer for a slow portal, since most states require rejecting a late bid.
Frequently asked questions
How do you fill out a construction bid form?
Fill it in exactly as the owner printed it. Price every line, or write no bid only where the form allows it. Recompute each extension and the total, list every addendum by number and date, attach the bid guarantee and have someone with authority sign and date each block. A second person should read the form aloud against your workbook before it goes out.
What is the difference between a bid form and a bid sheet?
A bid form is the owner's document in the bid package. You complete and sign it, and it carries your offer on the owner's terms. A bid sheet is looser: a contractor's line-item sheet for subs, or a homeowner's comparison sheet. Ask who wrote it and whether it binds you.
Can a federal bid be rejected for a missing signature?
On federal sealed bids, yes. FAR 14.405(c) treats a missing signature as minor only if other material shows you meant to be bound, such as a bid guarantee, or the bid carries a typed or stamped signature you formally authorized and proved before opening. Otherwise the bid is likely rejected.
Do you have to acknowledge addenda on a federal bid?
On federal sealed bids, yes, by the bid deadline. FAR 52.214-3 lets you sign and return the amendment or list its number and date on the bid form. A miss is minor only in narrow cases, such as a bid that shows you received the amendment.
What happens if an extension on a bid form is wrong?
Which figure governs is the owner's call, so find the rule in your instructions before bid day. On federal sealed bids, FAR 14.407-2(a) lets the contracting officer correct an obvious misplaced decimal point before award, after the bidder verifies the bid it intended. One state highway department's specifications, for example, let the unit price govern on a paper bid. Recompute every extension so the question never comes up.
