Altitude InspectionsYour infrastructure partners

Measured condition data on the infrastructure that is hardest to reach.

Altitude Inspections flies contact inspection drones on elevated water tanks, above-ground steel and HDPE pipe, power lines, and wind turbines. No scaffolding. No rope crews. You get real numbers so repairs get planned years ahead instead of after a failure.

What we do

Inspection data you can plan around, for the assets that are hardest to reach.

We get instruments onto tanks, pipe, power lines, towers, and turbines without scaffolding or rope crews, then turn the readings into findings your engineers, integrity managers, and operations leads can act on. You get measured results and a clear picture of what needs attention now and what can wait, at every stage of the asset's life.

Built for Colorado's electric co-ops

Find the problems that start fires before fire season does.

Co-ops maintain a lot of line with small crews, much of it in rough, remote country. Our drones inspect poles, crossarms, insulators, and hardware up close, flag hot spots with thermal imaging, measure vegetation clearance along the right-of-way, and test grounding and bonding by direct contact, coordinated with your line crews.

Fewer truck rolls and climbs

Inspect miles of line and hundreds of poles without sending a bucket truck or a lineman up every structure.

Catch it before it starts something

Thermal imaging finds overheating connections and hardware, and clearance measurements show where vegetation is closing in.

A record your board can see

Every structure gets dated, location-tagged photos and readings you can hand to your board, your insurer, or your wildfire mitigation plan.

An asset you can measure is an asset you can budget for.

Elevated tanks, above-ground pipe, power lines, and wind turbines all wear down out of easy reach. Getting eyes and instruments on them usually means scaffolding, rope access, lifts, or shutdowns, so inspections get stretched out and problems get found late. Our drones go to the structure and bring back the numbers.

Elevated water tank above a forested neighborhood

Municipal water and wastewater

Many of the elevated tanks serving Colorado communities went up around 1980. Measured coating and steel thickness lets you plan repaint and rehab years ahead instead of reacting to a failure. AMI collectors on those same structures get checked on the same trip.

Above-ground HDPE pipe run beside a road

Oil and gas operators

Above-ground water transfer and produced water lines, in steel and HDPE, plus pipe racks and other above-ground runs. Long stretches get inspected without crews walking every foot, and you get condition data you can rank and act on.

Electric co-ops and utilities

Pole, hardware, and right-of-way inspection for wildfire mitigation. Thermal imaging and vegetation clearance on every structure, without a truck roll to each one.

Wind turbine nacelle and blades at dusk

Wind energy

Lightning protection system testing on turbine blades, done by drone instead of rope teams. Faster turnaround per turbine means more of the fleet gets checked each season and less downtime waiting on access crews.

Corrosion does not wait for the budget cycle.

Pitting, coating breakdown, and through-wall loss build for years before anyone sees a leak. By then the fix is a replacement, not a repaint. Measuring early is how you stay on the cheaper side of that line.

Three examples of corroded pipe: heavy pitting, a hole through the wall, and rust buildup dripping from the underside
What reacting looks like.

Reacting

Condition is judged from the ground, from photos, or once every several years when a crew can finally get access.

Repairs get triggered by age, a complaint, a leak, or a failure someone finally notices.

The cost shows up as an emergency line item and unplanned downtime.

Planning

Coating thickness, wall thickness, and electrical test results measured at mapped points on the structure.

Readings you can compare survey to survey, so you can see which assets are wearing fastest.

Repaint, rehab, and replacement scheduled into the capital plan, with data to back the request.

Steel tank coating and wall thickness

Dry film thickness on the coating and ultrasonic thickness on the steel, taken by a drone that makes contact with the structure. Covers elevated tanks from roof to riser, plus ground storage tanks and standpipes.

You receive a report with every reading tied to its location and flagged against your spec, ready for a capital plan or a repaint RFP.

Above-ground pipe, steel and HDPE

Large black pipe running out over water toward a crane barge

Water transfer lines, produced water lines, pipe racks, bridge crossings, and any other above-ground run. Steel pipe gets coating and wall thickness readings, and insulated lines can be screened for wall loss without stripping the jacket. HDPE gets close-range 4K visual inspection for cracking, deformation, and damaged joints or supports.

Results come back by location along the run, so crews go straight to the sections that need work. On live oil and gas sites, the drone can carry a flammable gas sensor that reports %LEL in real time.

Power line and pole inspection

Distribution and transmission structures inspected from the air, with the problems that cause outages and fires flagged by location. Built for wildfire mitigation programs at electric co-ops and municipal utilities.

  • High-resolution visual inspection of poles, crossarms, insulators, and hardware
  • Thermal imaging for overheating connections, splices, and equipment
  • Vegetation clearance measurements along the right-of-way
  • Contact testing of grounding and bonding, coordinated with your line crews

Wind turbine lightning protection testing

Close view of a wind turbine hub, blades, and nacelle

The drone touches each blade receptor and takes a full-circuit resistance measurement through the down conductor to ground, following IEC 61400-24. It works at any rotor position, often in a single stop per turbine, on towers up to 820 ft. This is the test that has traditionally needed rope access teams on every blade.

Each receptor gets a resistance reading, so you know which blades need attention before the next storm season.

Lightning protection systems on structures

Checking a lightning protection system usually means rope access, a lift, or a crew working at height just to confirm continuity, bonding, and condition. We use the Voliro T to put a test probe directly on the system instead, even on tall or awkward structures. Less time at height, a smaller mobilization, and a faster inspection.

  • Direct-contact continuity and resistance testing
  • Air terminals, down conductors, and bonding connections
  • Probe placement on vertical, inverted, and complex surfaces
  • High-resolution visual condition assessment
  • Corrosion, damage, and missing component identification
  • Rooftop and elevated infrastructure
  • Reporting aligned with NFPA 780, IEC 62305, and CSA F417

AMI data collector inspections

Collectors mounted on tanks, towers, and poles get a close visual check of the unit, antenna, mounting, and cabling without a bucket truck or a climber.

Built to run at least once a year, so problems on your AMI network get caught before reads start dropping.

The drone that touches the steel

Most inspection drones only take pictures. The Voliro T is built to make contact, so it can take the same thickness and electrical readings an inspector would take by hand, without anyone leaving the ground.

Holds steady against the structure

Tilting rotors let it press a sensor flat against a wall, pipe, or tank bowl with up to 30 N of force and hold it there.

Works from any angle

Omnidirectional flight means it can test the underside of a bowl or a vertical riser as easily as a flat roof.

One drone, many sensors

UT, EMAT, coating thickness, pulsed eddy current, lightning protection, and gas monitoring payloads swap on site.

Sees what it touches

Two 4K cameras, one for the pilot and one for inspection, stream live to the ground crew.

Flies where GPS cannot

LiDAR and optical sensors navigate inside tanks and close to steel, with RTK GPS outdoors.

Built for Colorado

Rated to 16,400 ft above sea level and fits through a 20 in manhole for interior work.

What our drones measure

We match the drone to the job. Contact work is flown on the Voliro T, a contact inspection drone with tilting rotors that let it press a sensor flat against a wall, a pipe, or the underside of a tank bowl and hold it there. Sensors swap on site, so one visit can cover coating, wall thickness, and imaging. Thermal and vegetation surveys on power lines use dedicated imaging drones.

Sensors comply with ASTM E1816, EN 12668-1, ISO 16831, ASTM D7091, and IEC 61400-24 as applicable. Flights run in dry weather between 14 and 104 °F, with contact work in winds under about 18 mph. We schedule around Colorado weather windows.

What drone testing finds on above-ground pipe

Pipe usually fails from the inside out or under something: scale, insulation, a support. Each failure mode has a test that catches it early, and one site visit can run several of them.

We have used EMAT to find severe internal wall loss on ductile iron pipe before it failed.

Who leads the work

Portrait of Andrew J. Dingee

Andrew J. Dingee

Co-founder

Veteran Marine Corps fighter pilot

Andrew is a veteran Marine Corps fighter pilot who has spent more than three decades making high-risk operations safer and more predictable. He served 27 years in the Corps, flew the AV-8B Harrier as one of three East Coast airshow demonstration pilots, and retired as a Lieutenant Colonel after three combat tours. At United Airlines he managed safety and security for flight operations, and he still conducts quality assurance for Boeing 777 pilots there.

As Chief Standardization Officer and Vice President of HSE at bp, he built the oil and gas industry's first safety management system modeled on commercial aviation. His team ran 286 system investigations that produced more than 1,100 corrective actions, and a digital, quality-focused work program that cut HSE lagging metrics by up to 75 percent. He founded System Safety to help operators reduce human error and non-productive time.

That background shapes how we inspect: data collected the same way every time, and findings an owner can act on.
