Schedule of values and pay applications explained

Building the schedule

• Lines that match how the work is done, such as site work, concrete, steel, envelope, mechanical and electrical, so progress on each is easy to see in the field.
• General conditions and fee shown as their own lines or spread over the others, as the contract requires.
• Enough detail to measure. Large lines split into parts, such as mechanical rough-in and mechanical trim, make percent complete easier to agree.
• Values that reflect real cost, with markup spread fairly across the lines.
• Change orders added as new lines once signed, so the original sum and the changes stay separate. See change orders.

What a pay application shows

Most pay applications have a summary page and a continuation sheet. The continuation sheet lists each SOV line with:

• the scheduled value
• work completed from previous applications
• work completed this period
• materials presently stored, not yet installed
• total completed and stored to date, and percent complete
• balance to finish
• retainage, where it is figured line by line

The summary page totals those columns, takes off retainage and previous payments, and shows the amount due. The contractor signs it, often before a notary, and the architect certifies the amount it agrees with.

A worked continuation sheet with invented numbers

Contract sum $1,500,000. Retainage 5% of completed work and stored materials.

Check the scheduled values: 120,000 + 180,000 + 260,000 + 210,000 + 330,000 + 400,000 = 1,500,000.

Envelope materials stored on site: $22,000.

• Total completed and stored: 526,000 + 22,000 = $548,000
• Retainage: 548,000 x 0.05 = $27,400
• Earned less retainage: 548,000 - 27,400 = $520,600
• Previous certificates for payment: $401,500
• Due this period: 520,600 - 401,500 = $119,100

Check: 548,000 x 0.95 = 520,600, and 401,500 + 119,100 = 520,600. Overall percent complete: 548,000 / 1,500,000 = 36.5%, rounded.

Front-loading, and why it backfires

Front-loading means putting more value on early lines than their real cost, so the contractor is paid ahead of its spending. Suppose the contractor had moved $60,000 from mechanical and electrical to site work when it built the SOV.

• Site work, now $240,000 at 100%: billed $60,000 more
• Mechanical and electrical, now $340,000 at 10%: billed 34,000 instead of 40,000, $6,000 less
• Net extra billed this month: 60,000 - 6,000 = $54,000

Check: the new completed total would be 526,000 + 54,000 = 580,000. Line by line: 48,000 + 240,000 + 195,000 + 63,000 + 0 + 34,000 = 580,000.

The cash comes at a cost. Architects and owners watch for it and may reject the SOV. Late in the job, the underfunded lines leave too little money to pay the trades that do the last work, and if the contractor defaults the surety finds the remaining balance too small to finish. On the books it shows up as overbilling. See contractor financial ratios for over and underbillings.

Stored materials

Billing for materials not yet installed usually needs proof: invoices, a bill of sale, insurance, and for off-site storage, the owner's approval and often a site visit. Contracts differ on whether off-site storage is paid at all.

Common mix-ups

• An SOV that does not add up to the contract sum. It must total exactly.
• Retainage on this period only. It is figured on the total to date, then previous payments come off.
• Leaving stored materials out of the total. If the contract pays for them, they are earned before retainage.
• Mixing signed change orders into original lines. Add them as separate lines.

On the NASCLA exam

The bulletin lists subject areas, not topics. We place payment applications under Procurement and Contracting Requirements, 31 of the 115 scored questions. Write the steps in order: completed, stored, total, retainage, less previous, due. Then check by a second route.

Practice it

Run the same numbers in the free retainage calculator, check whether a job is billed ahead of or behind its cost with the free over and under billing calculator, and read lien waivers for the releases that travel with each payment.

Take the free 10-question check

Start the free 10-question check. It is weighted to the twelve NASCLA subject areas, needs no signup and explains every answer, so you see which area to study first.

The NASCLA Commercial course has a lesson for each of the 12 subject areas that shows which listed reference to open and how to apply it, original practice questions with every answer worked, and four timed practice exams of 115 questions on a 330-minute clock. Your scores come back by subject area, so you know where the next study hour goes. See the course.
