How to verify stored materials before approving a draw

A stored materials line item is the hardest thing on a draw request to check from your desk. The contractor submits an invoice for steel that hasn't been fabricated into anything yet, or switchgear sitting in a warehouse three states away, and asks you to fund it now because the schedule says it needs to be on hand in six weeks. You can't see it. You can only read about it.

That gap is exactly where overbilling tends to live. Most of the time it isn't intentional. Nobody on the owner or lender side has an easy way to confirm the material is real, is where the invoice says it is, and is headed for this job.

What counts as stored materials on a draw

Most schedules of values split stored materials into two buckets, and they carry very different risk.

On-site stored materials are physically on the project, usually in a laydown yard or a locked trailer, tagged and waiting for installation. You can walk to them. A superintendent can point at the pallet.

Off-site stored materials sit somewhere else entirely: a fabricator's shop, a bonded warehouse, a staging yard across town. AIA G702/G703 billing allows this, but most lenders and owners require a stored materials affidavit, a current invoice matching the quantity billed, proof of insurance on the material, and in a lot of jurisdictions a UCC filing so a supplier can't claim the same steel against two different buyers. If any one of those four pieces is missing, that's a reasonable basis to hold the line item until it shows up.

Verifying material on site is the easy half

For on-site stored materials, verification is mostly a walk and a cross-check. Someone (your inspector, your construction manager, your own eyes) confirms the material physically exists, matches the description and quantity on the invoice, and is tagged or segregated so it's clear it belongs to this job and not sitting there waiting to get used on a different project down the street.

Most inspection reports stop there and never check whether the project needs that material yet. If the schedule shows rough-in for that equipment package starting in week 14 and the draw request shows it as "installed" in week 9, something doesn't line up, and a site walk alone won't catch it unless the person walking it is also reading the schedule line by line.

Off-site stored materials draws need a different kind of proof

You can't walk a warehouse two counties over every draw cycle, and most lenders don't staff for it. In practice, off-site stored materials verification comes down to paper: the affidavit, the invoice, insurance, UCC filing, and sometimes photos the contractor supplies themselves. That last part is the weak link. A photo the contractor took and sent you is evidence, but it's not independent evidence, and everyone on both sides of the table knows it.

Some lenders send a third-party inspector to the warehouse for high-dollar line items. That works, but it's slow and it's not something you can do every month for every draw.

Tie the stored materials line to the schedule, not just the invoice

The question that protects a draw decision isn't "does this material exist." It's "is the project's observed progress consistent with a job that's ready to receive this material." If the self-reported percent complete for the surrounding scope matches what a camera sees on site week over week, a stored materials claim fits a believable pattern. If the claimed completion has been running ahead of what's visibly built for several draws running, that's worth a harder look before you approve the materials line too.

This is the gap Construction Progress is built to close: a weekly drone flight measured against your schedule, turned into a progress map you can set next to the draw request. It won't confirm what's sitting in a warehouse three states away, but it gives you an independent, site-wide record of what's built on site, so a stored materials claim either fits the pattern on the ground or it doesn't.

Questions worth asking before you sign off

• Does the affidavit match the invoice on quantity, description, and dollar amount, not just the total?
• Is there a current insurance certificate naming the right loss payee for that material?
• Has a UCC filing been recorded, or is one in process?
• Does the schedule call for this material soon, or is it being billed early?
• Does the observed progress on site support a contractor who's tracking toward the percentage claimed?

None of these questions is new. What's changed is how much of the answer you can get without waiting on someone else's photos.

If stored materials lines keep showing up ahead of what you can confirm, an independent weekly record of built progress is worth putting next to the next draw request.
