Rigging, steel, and the documentation that proves both.

A crane pick might look like the job from the ground. In reality, every lift is built on hours of planning, and it doesn’t end when the section is set.

We approach each structure as a complete system. Rigging must be precise. Steel must be installed, aligned, and torqued exactly to spec. Miss either side, and the structure won’t perform when it matters.

Our crews plan every lift with intent: ground-to-hook communication, sling verification, load control, and lift readiness. And once steel is set, we stay just as disciplined: bolt torque verification, plumb checks, hardware inspection, and documented sign-off.

That’s how towers are built to last.

Guyed vs self-supporting vs monopole.

The right tower for a site is driven by height target, equipment loading, land footprint, wind region, and sometimes aesthetics. Three main types, all in our wheelhouse:

  • Guyed lattice — cable-stayed triangular lattice. Most cost-effective for taller heights (commonly 200 to 500 ft). Small central pier, but a wide guy-anchor radius (typically 60 to 80 percent of tower height), so land requirement is significant.
  • Self-supporting — three-leg lattice with no guys. Compact footprint, harder on steel tonnage. Standard for 100 to 300 ft WISP, utility SCADA, and small-cell sites where land is tight.
  • Monopole — single-tube structure. Smallest visual profile, preferred for urban or sensitive sites. Typical heights 60 to 200 ft, foundations heavier per pound of tower than lattice.
  • ARE Telecom ballasted monopoles — ballast-weighted base, no excavation foundation. Fast-deploy for sites where civil work is impractical or permit-blocked.
  • Direct-embedment monopoles — pole set directly into an augered hole. Purpose-built for utility SCADA, oil and gas remote comms, and program deployments where speed-to-air matters. See our direct embedment service.

Bolt-up is where every tower lives or dies.

Every connection plate on a tower carries structural load designed against a specific bolt grade, bolt count, and installed torque value. We install to ASTM A325 or A490 spec as called out by your stamped drawings, torque-calibrated impact tools on every rig, and torque-verified on every connection before the section is released.

Missed or loose bolts are the single most common finding on post-storm tower inspections. It’s invisible from the ground. It’s not invisible in the closeout package if the job was done right.

Plumb, tension, and the instruments that prove it.

A tower isn’t done flying steel until it’s plumbed to L/1500 (TIA-222-I tolerance, roughly 1 inch per 125 ft), verified with a total station transit. On a guyed tower, plumb comes after every guy set is tensioned to engineered pre-load with tension-meter tooling on each cable, measured to the stamped drawing. Re-tensioning after the first temperature cycle is scheduled into the job, not an afterthought.

Our deliverable on every erection is a signed plumb-and-tension report with actual measured values per guy set. If an inspector or your engineer wants to verify, the numbers are there.

How it goes.

On-site erection for a typical 200 to 300 ft tower runs 3 to 10 days once the foundation is cured and the crane is on pad. Here’s how a typical build flows.

1

Pre-lift planning and mobilization

Crane capacity matched to the heaviest lift and farthest radius. Rigging walked and inspected. Lift plan signed by the crane operator and foreman before a single shackle gets pinned. Site staged with a drop zone, a staging area for sections, and a climb-rescue plan specific to the site.

2

Tower assembly and QC

Offload, catalog, and inspect every section on arrival: quantity count against packing list, steel inspected for shipping damage (no bent members goes up), hardware kits verified against the stamped drawing. Sections pre-assembled on the pad where the drawing calls for it. Nothing flies until the inspection is clean.

3

Base section set

Foundation cure approved by the engineer of record based on break-test results (generally 28 days at full strength). Anchor bolts checked for elevation and pattern. Base section leveled on base nuts with a total-station transit, not shimmed, and torqued in sequence per drawing. First plumb check happens here.

4

Section flies

Sections flown by crane or gin pole, lower-to-upper sequence per the engineer’s erection plan. Ground crew spots, radio check to hook on every lift, hand-on-the-tagline on every section. For guyed towers, temporary guys get rigged as the structure goes up to maintain stability section-to-section.

5

Bolt-up and torque

Every connection plate bolted to ASTM A325 or A490 spec. Torque-calibrated impact tools. Verification pass per bolt before the section is released. Touch-up galvanizing on any field abrasions. Connection documented in the closeout package.

6

Guy install and tension (guyed towers)

Guy wires installed per engineered layout, strand-to-hardware terminations made to manufacturer spec. Tension-meter tooling on each cable, tensioned to pre-load values from the stamped drawing. Re-tensioned after the first diurnal temperature cycle.

7

Plumb verification and safety climb

Tower plumbed to L/1500 with a total-station transit. Safety climb cable, climbing peg or ladder, and fall-arrest system installed per manufacturer requirements and ANSI A10.48. Lightning rod and obstruction-light mast installed if called for by FAA.

8

Punch-list and handover

Walk the tower with your engineer or inspector. Plumb-and-tension report, torque log, galvanizing inspection notes, and photo documentation delivered as the closeout package. Anything flagged in the walk gets closed before demob. Third-party structural audits sometimes run separately after demob; we coordinate with whatever reviewer your program uses.

Questions we get a lot.

What tower types do you build?

Guyed lattice — cable-stayed triangular lattice towers, most cost-effective for taller heights (commonly 200 to 500 ft in our WISP, utility, and broadcast work). Smaller central pier, significant guy-anchor footprint.

Self-supporting lattice — three-leg lattice without guys. Smaller land requirement, heavier steel per foot. Standard for 100 to 300 ft.

Monopole — single-pole structures. Smallest visual footprint, preferred for urban and sensitive siting. Typical heights 60 to 200 ft.

ARE Telecom ballasted monopoles — ballast-weighted base, no excavation foundation, fast deploy.

Direct-embedment monopoles — pole set directly into an augered hole, common on utility SCADA and oil and gas remote comms. See our direct embedment service.

How tall can you build?
Up to 300 ft on new construction. On existing towers, we’ve performed modification and antenna work as high as 690 ft (two-way communications tower, Dothan, Alabama). For new builds above 300 ft, contact us and we’ll scope it.
How long does tower erection take?

On-site work for a typical 200 to 300 ft self-supporting or guyed tower runs 3 to 10 days once the foundation is cured and the crane is on pad. The job starts with offload and assembly, not with the first fly:

  • Offload, catalog, and QC. Steel arrives, we count and inspect every section, check hardware kits, and reject anything shipped damaged.
  • Pad assembly where the drawing calls for it. Sections pre-assembled on the ground before they go up.
  • Then steel starts flying. Base section first, upper sections lower-to-upper per the engineer’s erection plan.

Other variables:

  • Tower type and height. A 150 ft monopole can be stood in a day. A 400 ft heavy-loaded guyed tower is a multi-week scope with multiple crane moves.
  • Weather. Steel stops moving when wind picks up. Sites get weather holds that aren’t on any schedule.
  • Access. A site 30 minutes off pavement with a 60-ton crane is a different logistics problem than a suburban pad with full paving.
  • Lift plan complexity. Tight crane radius, obstructed approach, gin-pole requirements, or unusual lift weights add time.

Quote is a fixed fee on a defined scope, with unit rates and change orders for field conditions (weather, crane availability, discovered conditions) so cost and schedule stay protected. We call timeline risks out line-by-line so your schedule math is honest.

What concrete cure is required before you set steel?
28 days for full-strength loading, or whatever the engineer of record approves based on break-test results. We don’t schedule steel crews off a round number; we schedule off the engineer’s sign-off on the cylinder breaks. That keeps us from stacking too early and keeps the project out of the kind of auditor conversation that costs everybody time. We coordinate with your civil contractor or run foundation work ourselves. See our foundations and civil service.
What bolt spec do you install to?

Every connection on every tower is installed to the bolt grade called out by the stamped drawing. In practice that’s almost always ASTM A325 or A490 high-strength structural bolts, depending on connection-plate detail.

We install with torque-calibrated impact tools (verified against a torque meter daily) and log torque verification on every connection in the rigging log. Undertorqued bolts are the single most common finding on post-storm inspections. We don’t leave them.

How do you check plumb on a finished tower?
TIA-222-I L/1500 tolerance (roughly 1 inch per 125 ft of height) verified with a total-station transit. For guyed towers, plumb is verified both after initial tensioning and after the first diurnal temperature cycle (cables stretch and relax with heat). Every handover includes a signed plumb report with measured values.
How do you set guy tension?
With tension-meter tooling on every guy cable, measured to the pre-load value from the stamped drawing. That’s the engineer’s way, and it’s the only way we do it. Re-tension after first temperature cycle is scheduled into every guyed-tower job.
Can you erect in winter conditions?
Yes, with appropriate cold-weather procedures. Steel is brittle below certain temperatures; A325 and A490 bolts have installed-temperature constraints; guy cable stretches differently at temperature extremes. We watch the forecast, apply cold-weather procedures per ACI and AISC guidance, and call a weather hold when conditions push beyond spec. Scheduling flex in the quote accounts for seasonal risk.
How much does tower erection cost?

Fixed fee on defined scope, with unit rates and change orders for field conditions. Quoted off your stamped drawings and equipment loading. Usable order-of-magnitude:

  • Small monopole (60 to 120 ft): low five figures for a straightforward monopole erection on an accessible site.
  • Self-supporting or guyed (180 to 300 ft): typically six figures, with steel tonnage, guy complexity, and crane logistics driving most of the spread.
  • Tall guyed or heavy-load broadcast (above 300 ft): high six figures and up. Quoted individually.

Send us the drawings and you’ll have a line-itemed quote inside a week.

Do you handle the foundation too, or just the steel?
Both. Most of our work is turn-key from dirt to dish. If you’d rather split civil from steel across two contractors, we can do steel-only and coordinate with your civil crew. See our new site builds service or the foundations and civil page for details.
What's your service area?
