Photo Documentation for T&M Work: A Subcontractor's Guide

Photo documentation for T&M work means taking dated, located, wide-to-close photos of the labor, equipment, materials and field conditions behind a time and materials ticket, and attaching them to that ticket the same day. Photos don’t replace a signed ticket. They back it up when someone questions the hours, the quantities or the conditions months later.

This guide covers what to shoot, how to shoot it, how to file it and where subcontractors most often lose the evidence they thought they had.

TL;DR

• Photos support a T&M ticket. They don’t replace the signature, the hours or the description of the work.
• Shoot wide first, then close. A close-up alone is easy for a reviewer to dismiss because it doesn’t show where the work happened.
• Photograph the same day, in the same order, and attach the photos to the ticket right away, not at month-end.
• Avoid faces, and never photograph an unsafe condition without reporting it in writing to the superintendent.
• One foreman, one routine, one place to store everything beats a perfect system nobody follows.

Why T&M work needs photos at all

T&M means you’re paid for actual costs: labor, equipment and materials. On public projects, the record of that work is formal. The City of Los Angeles Bureau of Engineering, for example, describes T&M records as needing specific data points for labor hours, equipment usage and materials, often submitted through daily logs or standardized field report forms. The ticket has to be signed by the owner’s or general contractor’s representative to carry weight.

That signature is the main event. Photos are the second layer. They matter when:

• The signer says later the crew was on site fewer hours than you billed.
• A reviewer says the work was already part of the base contract.
• A conflict with another trade (a ceiling you had to open, a wall you had to re-cut) changes who caused the extra work.
• The person who signed has left the project.

The American Subcontractors Association’s project documentation material lists photographs and videos alongside daily reports, correspondence and labor and material records as part of the paper trail a sub should keep. The lesson that runs through that material: memory is not evidence. Relying on verbal agreements for extra work is how claims die at closeout.

What photo documentation is called on a jobsite

If you search around, you’ll see the same practice under several names: site photography, project visual record, jobsite field logs and construction progress documentation. The AIA’s guidance on using photography to evaluate site work treats the purpose as the distinguishing factor: progress tracking, quality assurance or contract compliance.

T&M photography is the contract compliance kind. You aren’t making pretty progress shots for the owner’s newsletter. You’re building proof of three things: what the condition was before you touched it, what extra work you performed, and who and what was involved.

The shot list for a T&M ticket

A repeatable shot list is what separates a useful photo set from a camera roll full of random pictures. Here is a sequence that works for most commercial trades.

1. The context shot

Start wide. Stand back far enough that someone who has never visited the site can tell which floor, which room, which gridline or which wall you’re talking about. Include something permanent: a column number, a room sign, a door tag, a fixed fixture.

This is the step field teams skip most. The ASA material makes the point that a before-and-after pair is often not enough: wide shots showing where the work occurred should come before the close-up detail. Without them, a close-up of a cut pipe or an opened wall could be anywhere.

2. The condition shot

Now move in. Photograph the existing condition that triggered the extra work: the conflict, the unforeseen obstruction, the out-of-date drawing, the damaged substrate. If the extra work comes from a direction change, photograph the area as it was when the direction came.

3. The work-in-progress shot

Capture the crew’s work as it happens, not only the finished result. You want to show that the work took the time you’re billing. Take one or two shots at the start, midway and at the end. Include the equipment in use: the lift, the trencher, the scaffold you had to erect.

4. The materials shot

Show the materials staged or installed, with labels, sizes or packaging visible when it matters. If a material was special-ordered for the change, photograph it on delivery with the delivery ticket next to it.

5. The completed-work shot

Finish with a wide shot and a close shot of the result. Then tie the set to the ticket by photographing the ticket itself, or at least the ticket number, in the first or last frame.

Photographing the paperwork too

A photo of the signed ticket is cheap insurance. Paper tickets get lost in trucks and trailers. Take a clear, flat, fully lit photo of the signed ticket before it leaves your hands, and make sure the signature, date, hours and description are all readable.

If you want a tighter ticket process to go with your photos, our posts on the daily T&M ticket checklist and the 48-hour T&M ticket process with a three-way match walk through who signs what, and when.

Rules that make photos defensible

Shoot the same day

The photo needs to be as close in time to the work as possible. A set taken at the end of the week looks like reconstruction. Same-day photos, attached to the same-day ticket, tell a consistent story.

Keep the timestamp and location data

The ASA guidance emphasizes written, timestamped and location-tagged evidence over recollection. Practically, that means:

• Use the phone’s native camera or an app that preserves the original file with its metadata.
• Don’t screenshot, crop or edit the original. Keep it untouched and make copies for any markup.
• Make sure the phone’s date, time and time zone are correct.
• Turn location services on for the camera on company phones.

Name and file consistently

Pick a naming pattern and make everyone use it. For example: project number, date, ticket number, shot number. A folder of photos called IMG_4821 is nearly worthless in a dispute. A set that reads 2210-2026-10-23-T&M-014-03 can be retrieved in a minute.

Write a caption

A photo says what is there. A caption says why it matters. One line is enough: where it is, what the condition is, which ticket it belongs to. Do it while the foreman is still standing in the room.

Don’t rely on one phone

If the only copy lives on a foreman’s personal phone, it leaves when he does. Upload to a shared project folder or software system daily.

Faces, privacy and what not to shoot

The AIA’s guidance on site photography advises keeping construction workers’ faces out of photos unless identifying who did a specific task is truly necessary. When faces are captured, blurring them is a recommended risk management practice to avoid the need for signed releases. Frame shots on the work, not the people. If you need to show who was on the job, the timecard and the ticket’s crew list do that better than a face.

Safety is the other boundary. The same AIA guidance cautions against photographing unsafe conditions in a way that creates liability without a written report. If you spot one, document the area so the issue is visible, then notify the site superintendent in writing right away. Talk to your own safety lead or counsel about your company’s policy, because the rules on this vary by jurisdiction and contract.

A worked example

Say your drywall crew opens a wall for a patch and finds an undocumented duct run that wasn’t on the drawings. The GC’s superintendent tells your foreman to reframe around it. Here’s what a defensible record looks like:

1. Context: a wide shot from the corridor showing the room number sign and the wall.
2. Condition: a close shot of the duct run inside the opened wall, with a tape measure for scale.
3. Direction: the foreman texts or emails the superintendent that afternoon: what was found, what direction was given, and that the work is being tracked as T&M.
4. Work: two photos during framing, one at the start and one when it’s nearly done.
5. Material: the extra framing and board staged, with delivery ticket if purchased.
6. Ticket: the day’s hours by name, the equipment used, the materials, signed by the superintendent, then photographed.
7. Filing: everything attached to the ticket number before the foreman leaves the site.

None of this takes more than a few minutes if the foreman knows the order. It takes a lot longer to reconstruct later, and it may not be possible at all.

Where photo records fall apart

That fifth row deserves emphasis. Photos prove that work happened. They don’t prove someone with authority asked for it. Authorization lives in the written direction and the signature. Our guide to same-day change order documentation covers how to pair the two.

Connecting photos to hours and pricing

Photos support the story, but the money comes from numbers: hours, rates, markup and materials. Make sure the labor on your ticket matches the labor in your timecards. If the ticket says six hours for four people and your time records say otherwise, the best photo set won’t save you. For that side of the process, see our posts on construction timecard best practices for subcontractors and tracking labor hours on job sites. For how T&M compares with other pricing methods, read change order pricing methods.

If your ticket then feeds a formal change order, the six fields a change order needs is a useful checklist for what the office should assemble from the field’s photos and ticket.

Our perspective

We build software for commercial subcontractors, and the pattern we see is consistent: the field does the work, and the office can’t prove it. The problem is rarely a lack of effort. It’s that the photo is on one phone, the hours are in a spreadsheet, the ticket is in a truck and the email is in someone’s inbox. Four places, none of them linked.

So our advice is less about cameras and more about plumbing. Decide what the foreman does at the end of each T&M day, make it the same every time, and make the destination one place. If the photo, the ticket and the hours end up in separate systems, you’ll spend your margin on the reconstruction. That’s why we built the Hub around one login across labor tracking, change orders, bids and takeoff, so the data entered in the field is the data the office sees.

Start with a pilot on one crew. Get one foreman doing the shot list and same-day filing for a few weeks, see what breaks, then roll it out.

Where CO Hub fits

If you’re still stuffing paper tickets into a truck door, CO Hub is our tool for change order and T&M ticket management, with mobile access so the field can start the record on site and the office can follow it. It’s listed at 59 USD per month per company on our pricing page, and the pricing page also lists an active field worker fee of 2 USD per month per active field worker. You can run it alone or alongside Time Budge for labor tracking, so the hours on the ticket match the hours on the timecards. The Won2Build Hub ties the apps together under one login.

A simple routine to adopt this week

1. Give every foreman the five-step shot list on a laminated card or a phone note.
2. Set a naming convention and write it down.
3. Turn on location and check the date and time on every company phone.
4. Require a written confirmation of any verbal direction the same day.
5. Photograph every signed ticket before it leaves the site.
6. Upload everything to one shared location before the crew leaves, and have the office check it the next morning.
7. Once a month, pick one closed T&M ticket and see whether you could defend it using only what’s on file.

That last check is the honest test. If you can’t defend it in ten minutes, neither can your project manager when it counts.

FAQ

How many photos should a T&M ticket have?

There’s no official number. Aim for coverage rather than count: a wide context shot, the existing condition, work in progress, materials, completed work and the signed ticket. For a small job, that may be six to ten photos. For a multi-day change, repeat the set each day.

Are photos enough to get paid for T&M work?

No. Photos support the claim, but payment generally depends on authorization, a signed ticket and accurate hours, materials and equipment. Check your subcontract for notice and signature requirements, and talk to your attorney if a dispute is heading toward a claim.

Should workers’ faces be in the photos?

Keep them out where you can. AIA guidance recommends avoiding faces unless needed to show who performed a task, and blurring them if they’re captured. Your crew list and timecards document who worked.

What is another word for photo documentation?

Common alternatives are site photography, progress documentation, project visual record and jobsite field logs. On T&M work, most people simply say ticket photos or backup photos.
