Tower Maintenance & Inspection

A full-height climbing inspection to TIA-1019-A covers the whole structure, not just the parts that are easy to photograph.

• Structural steel. Corrosion, coating failure, section loss, weld condition, member distortion, ice damage, bird-nest and rodent impact.
• Connections. Flange splices, diagonal connection plates, and leg splices. Visual condition of every bolt, statistical torque sampling per ASTM A325 / A490 grade, missing-fastener check, tell-tale washer check where present.
• Guy hardware (on guyed towers). Strand condition the full length, grips, thimbles, turnbuckles, end-point hardware, and a visual strand count per spec.
• Anchor blocks. Concrete condition, rebar corrosion where exposed, rod condition at the embedment line, soil condition, drainage, and any ground-level signs of movement.
• Climb system. Safety-climb cable continuity, lanyard-slot wear, step-bolt integrity, ladder cage where present, transition-point hardware.
• Obstruction lighting. Function check against the FCC / FAA requirement for the tower’s height class, beacon photocell and flash-head condition, wiring at junction boxes. Lighting log pulled and reconciled against the field check.
• Grounding system. Above-grade bond condition, cadwelds that were once made but now show green oxidation, surge-suppressor condition at cabinet entry, tower-ring continuity (we pull fall-of-potential or clamp-on ground-resistance readings on sites where the scope calls for it).
• Transmission plant. Hangers at spec intervals, jumpers, entry-port boots, ice bridge, and weatherproofing condition. We open a sample of weatherproofed connectors on every visit to check the real state under the tape.
• Antenna and mount condition. Bracket torque, dissimilar-metal corrosion, bird-deterrent condition, and alignment drift.
• Compound. Fencing, gates, access road, signage, vegetation encroachment, and the drainage around the foundation.

Everything gets photographed with an elevation reference. Findings get written up with a severity flag, a recommended action, and a quoted remediation scope where applicable.

ANSI/TIA-1019-A is the industry standard for installation, alteration, and maintenance of antenna-supporting structures. It’s the document your structural engineer, your insurer, and most state broadband programs default to. It defines condition-inspection scope, recommended inspection intervals, and the evidence a qualified inspector is expected to produce.

The recommended cadence varies with tower class and exposure:

• Class I / II towers (low-consequence): every 3 to 5 years under standard exposure.
• Class III towers (high-consequence, public-safety, transport carrier): every 1 to 3 years, often annually for operators with strict SLAs.
• Post-event: any named storm, earthquake, lightning strike, or equipment-loading change triggers an event-based inspection before the structure re-enters full service.
• FAA-lit towers: lighting observation quarterly at minimum, typically logged alongside annual or bi-annual condition inspection.
• Insurance-driven programs: carrier or reinsurer often sets the schedule inside the policy. We work to whichever is stricter — your engineer’s recommendation, the insurer’s schedule, or the TIA-1019-A floor.

We build the inspection schedule against whichever framework drives your compliance obligation. For multi-site fleets, the whole program rotates through our crews on a published calendar so nothing falls out of cycle.

Single-site inspections are straightforward. Where the work gets interesting is running an annual condition-inspection program across a fleet of 10, 50, or 500+ towers without losing track of any of them.

How we run fleet programs:

• Tower register. A single source of truth per program: tower ID, coordinates, class, height, type, age, last-inspection date, open punch-list items, and next-due date.
• Rotating crew schedule. One or two crews rotate through the program on a published calendar. Travel and mobilization amortized across multiple sites per trip.
• Consistent reporting template. Every report built off the same schema so your engineer can compare tower-to-tower and year-over-year.
• Prioritized remediation plan. Findings ranked across the fleet by severity, not just per-site. Your capex planning gets a single document, not 200 separate reports to synthesize.
• Integration with your asset system. If you run a tower asset platform (Siterra, Accruent, Tower Numerics, or a home-grown tracker), we deliver in the format your system ingests.

Common programs we run: WISP fleets (50 to 200+ towers), utility communications towers for rural electric cooperatives, state broadband grantee portfolios, county public-safety networks, and tribal-nation broadband operators with regional tower footprints.

After a named storm, microburst, earthquake, or lightning event that visibly moved or damaged the structure, you need a qualified-inspector condition assessment before the tower is declared safe to run at full load.

Event-based response scope:

• Expedited mobilization. Crews running out of Alabama and Texas typically on-site inside 24 to 48 hours in the lower 48, weather and access permitting.
• Damage assessment. Full-height climbing inspection with emphasis on structural members, guy hardware, anchor blocks, and foundations.
• Plumb-and-tension spot check to quantify any geometric displacement (deep correction work handled on Plumb & Tension).
• PE coordination for anything outside the engineer’s re-certification envelope. We don’t clear the structure for service until your PE has signed off on whatever the event produced.
• Documented condition report with photos, severity grading, and a remediation scope quoted at the same visit. Your insurer and your engineer get the evidence they need in one package.

For high-consequence infrastructure — public-safety transport, utility backhaul, hospital microwave — post-storm response is a planned capability, not a scramble. We pre-register on-call with the operators who want that coverage.
