AIA Progress Billing: Why the Schedule of Values Decides Whether You Get Paid on Time

On an AIA-format pay application, every dollar you request is measured against one document agreed before the first bill: the schedule of values. AIA Document G703, the Continuation Sheet, lists each line’s scheduled value, the work completed in earlier periods and this period, materials presently stored, the total to date, the percentage complete, and the balance to finish. The cover form, G702, Application and Certificate for Payment, carries the totals and the contractor’s signed certification. If the schedule is split badly or priced unevenly, every application inherits the problem, and the payment slows down at the point where someone checks the numbers.

What the Schedule of Values Allocates

A schedule of values (SOV) divides the contract price among the parts of the work: sitework, foundations, framing, mechanical rough-in, finishes, and so on, so that the lines add up to the contract sum. It allocates price, not cost. Each line carries its share of the overhead, risk, and profit built into the contract price, not only the labor and material it will consume.

That distinction decides whether a schedule is front-loaded. A line whose direct cost is $60,000 is not “overpriced” just because its scheduled value is higher; some markup belongs on every line. The question an owner or lender asks is whether the markup is spread in a way that tracks the work, or whether it has been moved toward the lines that will be billed first.

How the Split Controls the Cash

Granularity in the schedule is granularity in payment. If framing and foundations share one line, progress on framing can be billed only as a share of that combined line, and the reviewer has to judge the percentage of two different activities at once. Split into separate lines, each can be billed as its own work advances, and each percentage is easier to defend.

The opposite mistake also costs money. A schedule with more lines than the field can report on accurately invites estimated percentages, and estimated percentages invite cuts. A useful test for each line is whether someone on site could state its percentage complete from something countable or measurable: units installed, quantities placed, rooms finished. Where the answer is no, the line is either too broad or too fine.

Front-Loading, Measured Against Price

Front-loading moves contract price from late lines to early lines, so that early applications collect more than the early work is worth. The way to see it is to compare each line to a balanced allocation of the same contract price, not to its cost.

For example, assume a $500,000 contract with $400,000 of estimated cost, so the price carries a 25% markup on cost. A balanced schedule applies that same markup to every line. A front-loaded schedule keeps the total at $500,000 but shifts $40,000 of price from finishes to sitework.

Line	Estimated cost	Balanced scheduled value	Front-loaded scheduled value
Mobilization and sitework	$60,000	$75,000	$115,000
Structure	$180,000	$225,000	$225,000
Mechanical, electrical, plumbing	$80,000	$100,000	$100,000
Finishes	$80,000	$100,000	$60,000
Total	$400,000	$500,000	$500,000

Under the front-loaded version, sitework bills at 192% of its cost (115,000 ÷ 60,000), and finishes bill at 75% of theirs (60,000 ÷ 80,000). The $40,000 collected early is not extra money; it is money the finishes will not have when they are built. Owners, lenders, and the architect reviewing the application can see the imbalance by comparing lines with each other, and on a schedule they distrust, every later percentage gets challenged.

A contract can also justify an uneven line. Mobilization may carry real early costs such as bonds, insurance, and site setup, and a line that bundles those costs is not front-loaded just because it is large. The defense is a schedule whose markup can be explained line by line.

The Arithmetic of One Line

The G703 columns make the billing calculation mechanical once the percentages are honest. Take the balanced structure line above, scheduled at $225,000, and assume the contract withholds 5% retainage.

G703 column	Amount
C. Scheduled value	$225,000
D. From previous application	$90,000
E. This period	$45,000
F. Materials presently stored	$10,000
G. Total completed and stored to date (D + E + F)	$145,000
Percent (G ÷ C)	64.4%
H. Balance to finish (C − G)	$80,000
Retainage at 5% of G	$7,250

Assuming the stored materials were delivered this period, the amount due for this line is the new work and the newly stored materials less retainage on them: $55,000 less $2,750 is $52,250. Summed across every line, the same logic produces the G702 totals. Stored materials sit in their own column because they have been bought and delivered but not installed, and the contract decides what documentation supports billing them, so the file for that column should hold the invoice, the delivery record, and anything the contract asks for about storage and insurance.

Change Orders Become New Lines

An approved change order adds scope and price, and the clean way to bill it is a new line on the schedule, not a quiet increase to an existing one. A separate line keeps the original allocation visible, lets the reviewer match the billing to the signed change order, and keeps the work-in-progress report honest because the contract value and the estimate move together. A change that is priced but not yet signed has no line, and billing against it is one of the reasons an application comes back. That is a billing rule, not a revenue rule: under ASC 606-10-25-10 and 25-11 in ASU 2014-09, a change approved by the parties, including orally or through customary practice, can enter the contract value used for revenue recognition before it can be billed, with an unpriced change estimated as variable consideration under the standard’s constraint.

Lien Waivers in Florida: What the Statute Actually Says

The lien waiver that travels with a pay application is where the exact wording of Florida’s statute matters. Section 713.20, Florida Statutes sets out the rules for construction lien waivers:

• Subsection (2): a right to claim a lien may not be waived in advance, and a waiver can cover only labor, services, or materials already furnished. An advance waiver is unenforceable.
• Subsection (4): when a lienor must sign a waiver to receive a progress payment, the waiver “may be in substantially the following form,” and the statutory progress form states that it “does not cover any retention or labor, services, or materials furnished after the date specified.”
• Subsection (5): a separate form for the final payment, which has no such carve-out.
• Subsection (6): a person may not require a lienor to furnish a waiver that is different from the forms in subsections (4) and (5).
• Subsection (7): a lienor who signs a waiver in exchange for a check may condition the waiver on payment of the check; without a payment bond protecting the owner, the owner may withhold the amount of an unpaid check from payments to the contractor until the condition is satisfied.
• Subsection (8): a waiver that is not substantially similar to the statutory forms “is enforceable in accordance with the terms of the lien waiver or lien release.”

Three practical rules follow. First, the “through” date on a progress waiver should match the work actually being paid, because the waiver releases rights for work furnished through that date. Second, the statutory progress form already excludes retention, so a progress waiver on another form should be read for whether it gives up retainage rights the statutory form would have kept. Third, a nonstandard form is not void in Florida; subsection (8) enforces it by its own terms, which is the reason to read it before signing rather than assume it will fail.

Section 713.20 does not label waivers “conditional” or “unconditional.” The Florida mechanism is subsection (7): a waiver given for a check can be made conditional on the check clearing. A final waiver signed on a progress payment releases more than the payment covers, and the final-payment form in subsection (5) has no retention carve-out. Because a waiver gives up lien rights for the work it covers, a waiver that departs from the statutory forms is worth showing to a Florida construction attorney before it is signed.

Who Decides Percent Complete

Each line’s percentage is a judgment, and the contractor signs a certification that the work is complete as stated. When the contract gives the architect a certifying role, the architect reviews the application against the work in place, and the amount approved can be less than the amount requested. The percentage that survives that review is the one supported by something on site: units counted, quantities measured, or, for activities that resist counting, an estimate of effort spent against effort remaining that the project manager can explain.

Claiming a little more than is built pulls cash forward the same way front-loading does, and it carries the same cost. The reviewer cuts the line, and every later percentage is read with more suspicion.

Why Applications Come Back

Rejected or reduced applications trace back to numbers that do not tie out:

• G703 lines that do not sum to the G702 totals.
• Percentages that claim more progress than the site shows.
• Stored materials billed without the support the contract requires.
• Retainage calculated at a different rate or on a different base than the contract states.
• Billing against a change order that is not yet approved.
• A lien waiver whose dates or amounts do not match the payment.

Each is avoidable with a review before submission: re-add the columns, compare each percentage with the field report, and match every new line to a signed change order.

Before the First Application

The warning that matters is that the schedule of values is decided once and billed against for the life of the job. Build it as an allocation of price that tracks the work, split it at the level the field can report, keep change orders as their own lines, and sign Florida progress waivers on the statutory form or with a lawyer’s review of the alternative. A schedule built that way gives the reviewer nothing to question, which is what keeps the check moving.

This guide explains AIA progress billing and Florida lien waivers as general information, not legal or accounting advice. Payment terms come from your contract and lien rights depend on the facts of the job, so confirm both with a Florida construction attorney or a qualified accountant before relying on them.
