You're not buying a highlight reel, and you're not buying a survey map. Progress monitoring is change detection: the same vantages, week over week, so a superintendent can see what moved, what got built, and what the site did to itself.
What you pay for is a repeatable pair — last Thursday against this Thursday. If the framing jumps around, you have a pile of drone photos, not monitoring.
I fly commercial work out of Springdale, Arkansas. Eight years on pads and civil sites taught me this: supers are already drowning in pictures. They hire a pilot when they want one consistent view of change, not another random flyover.
This is not a weekly orthomosaic package. If you need a dated, measurable nadir map you can overlay on the civil set, that is a different hire: How to Hire a Pilot for Weekly Construction Orthos.
What progress monitoring is
Monitoring here means change detection. Same weekday when weather allows. Same two or three vantages. Same altitude band. A short set of stills you can set side by side. Optional: a short clip if someone asked for it. The product is the comparison, not any single pretty frame.
Typical change you are hiring to see:
- Earthwork extent: the cut grew west, the fill came up, the haul road shifted, the slope is still open.
- Structure progress: which decks, walls, or steel went in since the last pass.
- Site logistics: laydown ate the fire lane, the crane moved, the steel landed or it didn't.
- Condition after weather or a change-directive week.
A georeferenced GeoTIFF, a GSD target, and cut/fill from a surface model belong on the ortho sibling, not in this PO.
What your superintendent actually gets
A change record they can find
Name the files with the date and the vantage. Put them in Procore, ACC, or the drive the project already uses. When someone asks what the south lot looked like before the extra laydown showed up, you have a Thursday, not a memory. The value is the time series.
Earthwork as a before-and-after, not a pay quantity
You are not paying a dirt contractor from these photos. You are getting a common picture of what changed. The cut is wider. The stockpile moved closer to the gate. The swale is holding water. That is enough for a super and a grading foreman to stop arguing about whether anything happened this week.
If you need volumes or a surface in the project coordinates, hire the weekly ortho as its own line. Don't mix the bids.
Logistics before they become a delay
Haul roads pinch. A new laydown eats the fire lane. A crane swing needs a pad that still has a connex on it. A monitoring pass from the same high corner shows circulation a person at ground level cannot. Ask for one overhead photo and one or two locked obliques. That pair is usually enough to see the change.
A record when weather or a claim shows up
Storm Friday. Monday someone asks what was open. A dated progress set is a condition record. Same for a disputed delivery or a weekend of work you did or did not authorize. You are keeping a visual log with a date stamp, not building a legal brief.
What this is not
Don't hire progress monitoring if what you want is a cinematic owner video, a one-time "before" shot with no follow-up, or a stamped topographic surface. Those are different products.
Don't treat these photos as pay quantities or as a substitute for a weekly ortho program. Change detection answers "what is different." An ortho answers "measure it."
Don't hire a hobbyist because "it's just photos." Progress photography for a GC or owner is commercial work. Part 107 applies. So does the COI your risk team already asks for on any sub.
How to hire
Write the scope like a repeating field operation built for comparison.
Operator checklist
- Current FAA Part 107 Remote Pilot Certificate. Ask for the number.
- Certificate of insurance. Many GCs ask for $1 million commercial general liability, GC and owner as additional insureds, plus aviation / unmanned aircraft coverage. Use your risk team's minimums.
- Repeatable capture. Same vantages, same altitude band, same weekday. If they cannot fly a consistent frame, you cannot detect change.
- Airspace plan. If the site sits under controlled airspace, they file LAANC or work an ATC path before they show up. Confirm they will. Need the law on LAANC? dronelaws.us.
- A habit of delivering files, not just flying. Ask who drops the folder and how fast.
Deliverable checklist
- A short set of stills from named vantages (north gate, south pad, crane). JPEG is fine.
- One overhead of the active work area. This is a photo, not a georeferenced ortho, unless you add that scope on the sibling hire.
- Optional: a 30-to-60-second clip for the owner meeting, or a one-page contact sheet for the OAC packet.
- Date, site name, and vantage in the filename.
- Drop location the project already uses.
Ask for turnaround in writing. A common window is 24 hours from wheels-down to files in the folder.
Cadence and weather slip
Weekly is the usual rhythm on an active civil or vertical site. Biweekly is enough when the site is slow. A short daily burst is rare and usually reserved for a critical window — a weekend pour sequence, a road closure, a post-storm reset.
Weather will slip flights. Rain or winds above the aircraft limit cancel. The operator proposes the next flyable slot the same week. If they miss the week, you still get a dated note. Don't pay for a flight that cannot produce a usable still. Do pay for the operator to come back.
What to put in the RFP
- Site address, the active work area, and the two or three vantages you want locked.
- Weekly or biweekly, preferred weekday, and the weather-slip rule.
- Deliverables: stills, one overhead photo, optional short clip. Say if you also want a measurable weekly ortho as a separate line.
- Where to drop files (Procore, ACC, a shared drive).
- Part 107 proof, COI with additional insureds, and who files airspace.
- Start date and expected duration.
- Site contact for the gate and the no-fly areas (crane, comms, neighbor).
If you don't have a pilot yet, search the directory by state or post that RFP on findadronepilot.com. You hire the operator directly. There's no broker in the middle and no commission on the job.
Hire the change record, not the reel
Your superintendent already has more random photos than they can file. What they don't have is one dated, repeatable look at what changed — earthwork, logistics, and the building — from the same corners.
Hire for that. Part 107, COI, named vantages, a weekday cadence, and a weather slip. Then put the files where the Monday meeting can open them.
