Reading path 01: Aerial construction
Construction Helicopter Services
Construction helicopter services execute 10 to 15 external load lifts per hour under 14 CFR Part 133, placing loads up to 28,000 pounds with no street closures, no tower crane assembly, and no outrigger ground-bearing work. This page breaks down how operators engineer each pick, how a Congested Area Plan moves through FAA review, and how estimators model an aerial lift program inside a master bid.

The four missions
What Construction Helicopter Services Cover
A crane helicopter for construction is a Part 133 external load aircraft flying Class B loads: freight lifted free of the ground on a belly hook or longline, moved from a staging area to a set point in minutes. That single capability breaks into four distinct aerial construction mission profiles, each with its own planning discipline:
Mission profile 02
Steel & Infrastructure
Precision steel placement where crane geometry fails: penthouse members, spires, bridge sections, long-reach picks over occupied structures.
Field study 02
Mission profile 03
Modular Building Placement
Complete modules, equipment shelters, and prefab sections set with zero ground footprint, flown only against certified module weights.
Field study 03
Mission profile 04
Concrete Bucketing
High-cycle aerial concrete delivery to pours a pump or truck cannot reach, with cold-joint risk engineered out of the pour sequence.
Field study 04
Every profile runs on the same doctrine, documented in full in the Part 133 External Load Operations reference: certified load weights, engineered rigging, and a pilot in command with final legal authority over every pick.
The bid math
Why Estimators Put Helicopter Construction Lifts in the Bid
The crane line item in a competing bid rarely shows its full weight. Quantity takeoff captures the daily rental rate. It usually misses the mobilization bleed around it. That gap is where a helicopter lift wins the number.
| Hidden crane cost | Typical exposure | Helicopter equivalent |
|---|---|---|
| Tower crane assembly and teardown | $60,000 to $100,000 before the first pick | None. The aircraft arrives and departs under its own power |
| Street closures, lane-use fees, police details | $50,000+ on constrained urban work | Zero ground footprint. The Congested Area Plan secures the fall zone instead |
| Outrigger ground-bearing analysis, mats, cribbing | Engineering fees plus days of schedule | Not required. No outrigger loads touch the site |
| Multi-week rental exposed to weather standby | The rental clock runs whether the crane picks or not | The lift program compresses into hours; weather risk shrinks with it |
| Tenant and operations disruption | Lost-revenue claims, after-hours premiums | Occupied facilities keep operating; most lift windows close before lunch |
At 10 to 15 lifts per hour, a weekend crane program becomes a single morning. That is not a convenience claim. It is a schedule-certainty instrument: fewer exposure days, less labor stagnation, a tighter critical path, and a margin that survives contact with the field.
The same math runs in reverse, and an honest planner runs it that way. The full model, including the scenarios where the crane wins, is published in the total cost analysis.
The cycle rates
How Many Lifts Per Hour Can a Construction Helicopter Execute?
An aerial construction helicopter's cycle rate depends on airframe, load weight, and the distance between staging and set point. Under a tight staging plan with loads pre-rigged, these are the working numbers:
| Aircraft | Category | External load capacity | Cycle rate | Construction profile |
|---|---|---|---|---|
| Columbia BV-234 Chinook | Standard | 28,000 lbs max; 20,000 lbs precision placement (standard day, sea level) | 10-15 picks/hr | The heavy lifter legally cleanest for congested-area work |
| Erickson S-64E/F Air Crane | Restricted | 20,000-25,000 lbs | 15-20 picks/hr | Aft-facing pilot station for precision sets |
| Sikorsky S-61N Mk II | Standard | 10,000 lbs (with Carson composite blades) | 12-15 picks/hr | Mid-size RTUs, shelters, light steel |
| Bell 214B | Standard | 8,000 lbs longline; 6,614 lbs precision | 15-18 picks/hr | Precision members; 14,000 ft density altitude capability |
| Kaman K-MAX K-1200 | Restricted | 6,000 lbs (sea level, ISA +15C) | 20-25 picks/hr | Highest cycle rate in class; lowest downwash for repetitive picks |
| Bell 412EP / 212 | Standard | 4,500 lbs / 3,500-4,500 lbs | 15-20 picks/hr | Light packages; twin-engine redundancy on the 412EP |
Payload is dynamic, never static. Density altitude cuts engine power roughly 3 percent per 1,000 feet, and a 10 degree Fahrenheit rise above standard adds about 600 feet of density altitude. Disciplined operators validate every load parameter against forecast conditions on lift day, not against the brochure number.
Certification category is a hard legal gate, not a preference. Restricted-category surplus airframes (CH-47D, S-64, K-MAX) cannot operate over densely populated areas without specific FAA authorization under 14 CFR 91.313. When the set point sits over an occupied downtown block, the standard-category BV-234 or S-61N is often the only lawful heavy option. Experienced operators select the airframe after surveying the site, never before.
The rulebook
Who Handles the FAA Compliance on a Construction Lift?
The operator does, and a well-built bid says so with precision, because compliance scope is where aerial line items get challenged in review.
14 CFR Part 133 governs every rotorcraft external load operation. The certificate, the Rotorcraft Load Combination Flight Manual, and the load class determinations are the operator's burden, not the contractor's.
Congested Area Plans under 14 CFR 133.33(d)(1) and AC 133-1B are required for lifts over congested areas. The operator engineers the plan: flight routes, fall-zone security agreements, emergency jettison corridors, and coordination with the police perimeter. Contractors should budget at least 5 working days of FSDO review into the schedule; experienced operators file early so the review never sits on the critical path.
OSHA 1926.551 defines the ground crew standard: PPE, tag line discipline, rigging inspection, and static discharge protocol (the load is grounded with a discharge conductor before any crew member touches it).
ASME B30.20 and B30.26 govern below-the-hook devices and rigging hardware. Slings carry a 5:1 minimum design factor. The pilot in command holds legal authority over rigging integrity and can refuse any lift. The contractor's side of the ledger is exact: certified load weights and engineered pick points.
ANSI S12.9 is the community noise measurement standard behind most urban noise ordinances. Where a municipality requires a noise assessment, operators typically manage it inside the CAP timeline.

The ground crew
What the Contractor's Ground Crew Does During the Lift
Role clarity is a schedule tool. Before lift day, the operator delivers a ground operations brief that assigns every position: riggers at staging, receivers at the set point, tag line handlers, and the signal person on radio with the flight crew. The contractor's crew hooks, steadies, and lands loads. The flight crew flies, manages the hook, and owns the go or no-go call on every pick. Rotor wash at the set point can exceed 100 mph, so site securing (loose material, temporary fencing, dunnage staging) is completed and verified before the aircraft launches.
The honest comparison
When a Ground Crane Is the Right Call
A disciplined lift plan vets the engineering outcome, not the flight. A ground crane wins in three recurring cases: a single heavy pick with clear street access and no closure costs, long-duration steady lifting measured in weeks rather than hours, and loads beyond 28,000 pounds, the practical ceiling of the civilian heavy lift fleet. When a job fits one of those cases, a credible operator says so in writing. That is the standard a technical vetting partner owes an estimator, and it is why solution-agnostic lift recommendations survive owner and CM scrutiny.
The bid package
What a Complete Aerial Logistics Appendix Contains
Speed only wins the contract if the estimator can price it. On active bids, established operators deliver a logistics appendix formatted to drop into the master bid: fixed-price lift line items, cycle-rate assumptions tied to a named airframe, insurance certificates (aviation liability, on-hook cargo coverage, waiver of subrogation, additional insured status), the CAP filing timeline against the notice to proceed, and the ground crew interface plan. When that appendix is done well, the quantity takeoff stays clean, the logistics section reads like the aviation contractor wrote it, and the number holds up in review.

Frequently asked questions
What Estimators Ask About Construction Lifts
The civilian heavy lift ceiling is 28,000 pounds, set by the Columbia BV-234 Chinook. The Erickson S-64 Air Crane lifts 20,000 to 25,000 pounds, the Sikorsky S-61N carries 10,000, and the Kaman K-MAX carries 6,000 at the highest cycle rate in its class. Working payloads are validated against density altitude on lift day, never against the brochure number.
A Congested Area Plan (CAP) is the FAA-required plan under 14 CFR 133.33(d)(1) for external load operations over congested areas. It documents flight routes, fall-zone security, and emergency jettison corridors. The Part 133 certificate holder engineers and files the CAP, coordinates the FSDO review, and budgets at least 5 working days for that review in the lift schedule.
The contractor's crew rigs loads at staging and receives them at the set point under OSHA 1926.551: rated PPE, tag line control, and no contact with the load until a grounding conductor discharges static. The operator supplies the ground operations brief, assigns positions, and puts a signal person on radio with the flight crew.
A ground crane wins on a single heavy pick with clear street access, on long-duration steady lifting measured in weeks, and on loads beyond 28,000 pounds, the ceiling of the civilian heavy lift helicopter fleet. Helicopters win when closures, mobilization, or site access make the crane's hidden costs exceed the flight program.
Require aviation hull and third-party liability coverage, on-hook cargo coverage (distinct from general cargo liability), a waiver of subrogation, and additional insured status naming the GC and owner. Certificate limits should be sized to the project; owners on major commercial work commonly require aviation liability limits of $10 million or more.
