Tower Audits Without Sending Anyone Up the Structure
Structural condition capture, RAD center and azimuth verification, compound and lease mapping, and 3D digital twins accurate enough for a structural engineer to work from. All of it from the ground.
Every question about a tower used to require a climber
Is that mount plumb. Has the galvanizing gone. What azimuth is the sector actually at, versus what the drawing says. Historically the only way to answer any of it was to schedule a crew, brief the climb, and accept both the cost and the exposure. So the questions got batched, and the answers arrived late.
Reality capture removes the climb from the equation. We fly the structure and return a set of images indexed by height and a measurable 3D model of the tower and its compound. The engineer who needs to check a mount does it from a desk, and the answer takes minutes rather than a mobilization.
That changes the economics of a portfolio, not just a site. When a tower audit costs a flight instead of a climb, auditing all of them on a consistent schedule becomes realistic, and the records actually compare to each other.
What we capture on a tower site
Scope depends on whether you’re checking condition, verifying an install, or preparing a co-location application. Each card links to the service page behind it.
Structural condition audits
Systematic 360-degree capture of guy wires, bolts, welds, step pegs, coatings, and grounding, indexed so findings tie to a height.
RAD center and azimuth verification
Antenna heights, tilt, azimuth, mount geometry, and cable routing measured against the drawings rather than assumed to match.
Compound and lease mapping
Shelters, cabinets, generator pads, ice bridges, fence lines, and access routes documented as a measurable site plan.
3D digital twins
Photogrammetry processed into a navigable model an engineer can measure, and a co-location applicant can evaluate without a site visit.
Thermal on powered equipment
Radiometric passes over cabinets, rectifiers, and generator sets to catch thermal anomalies while the site stays live.
Post-storm condition capture
Rapid documentation after a named storm, so you know which sites need a crew and which are fine before you dispatch anyone.
What changes when the audit stops requiring a climb
- Climber exposure goes to zero. For condition and verification work, nobody leaves the ground.
- Co-location moves faster. Structural engineers get a measurable model instead of waiting on a mount survey.
- Findings tie to a height. Imagery indexed by RAD center means a defect has an address, not just a photo.
- Portfolios stay comparable. The same flight pattern across every site makes year-over-year change readable.
- Sites stay on air. Capture happens without powering anything down or interrupting a carrier.
- Disputes get shorter. Dated evidence of as-built condition settles arguments about what was installed when.
Deliverables a structural engineer can actually use
Tell us the modeling environment and the coordinate system before we mobilize and the files land ready to work in.
Point clouds
E57, LAS, and OBJ for structural modeling and mount analysis.
Height-indexed imagery
Visual libraries organized by RAD center and azimuth so findings map to the structure.
Site plans
Compound geometry and lease boundaries in CAD-ready formats.
Digital twin
A navigable model for remote evaluation and co-location review.
Condition report
Defects ranked by severity with the height and face they were found on.
Thermal data
Radiometric files for powered ground equipment where that’s in scope.
Have a site or an asset that needs documenting?Tell us the asset and the deadline. We’ll scope it and price it.
The services behind this work
Tower and telecom capture questions
What tower owners, carriers, and structural engineers ask us most.
Can a drone audit really replace a climbing inspection?
For condition assessment and verification work, yes, and it usually produces a better record. A camera can hold a position and capture every face systematically in a way a climber working at height can’t. What a drone can’t do is torque a bolt or replace hardware, so hands-on work still needs a crew. We’re removing the inspection climb, not the maintenance one.
How accurate is the azimuth and tilt measurement?
Accurate enough to catch an install that doesn’t match the drawing, which is the question people are actually asking. We derive it from a photogrammetric model built with control rather than from a single image, and we’ll state the accuracy we achieved in the deliverable rather than making you assume it.
Do you need the site taken off air?
No. Capture happens from outside the structure with the site fully live, so there’s no service interruption and no coordination with a carrier’s maintenance window. RF exposure is managed through standoff distance and flight planning.
Can you work across a multi-state portfolio?
Yes, and standardizing the capture is the main reason to do it that way. One operator and one flight specification across the portfolio means every site produces the same deliverable, which is what makes the records useful in aggregate rather than site by site.
What do you need from us before mobilizing?
Site coordinates, structure type and height, current drawings if you’ve them, access instructions, and whoever we need to notify. If a site sits under controlled airspace we handle the authorization, and we’ll flag anything that can’t be flown legally before you’re invoiced for a trip.
Will the model work for a co-location application?
That’s one of the most common uses. The applicant’s structural engineer gets a measurable model of the existing loading and mount geometry, which shortens the analysis considerably compared with waiting on a mount survey. We deliver in the formats structural firms typically request.
