Crane / hiab operator on a building job: licensing, lift plans, and engaging the operator

TL;DR

A crane or hiab on any building site (Class 1a houses through to Class 2 mid-rise apartments and Class 3-9 commercial) is licensed, HRCW, and priced by the hour with a minimum. Class 2 commercial work is the natural step up from residential: same plant categories, same licence classes, but bigger reach, bigger ground-bearing demands, and tighter exclusion-zone planning on a constrained urban site. Vehicle-loading cranes (truck-mounted hiabs) at or above 10 metre-tonnes capacity require a class CV high risk work licence under Schedule 3 of the model WHS Regulations (verified 2026-05-13). Mobile cranes have their own classes (C0/C1/C2/C6 slewing by capacity, CN non-slewing over 3 t). Powered mobile plant triggers the SWMS requirement under regulation 291; any non-trivial lift needs a written lift plan with an enforced exclusion zone. The two job-killers: a crane that arrives without ground bearing confirmed (outrigger drops), and a lift booked without enough swept-path room between boom, eaves, and the neighbour’s overhead service.

What this trade covers

Three predictable lift scenarios on a building site:

Truss and beam lifts: roof trusses, ridge beams, LVL spans, steel posts where manual handling is unsafe
Slab and pool shell deliveries: precast slabs, plunge pool shells, prefab modules onto a prepared pad
Heavy material set-down: brick, block, and tile pallets to upper levels; long steel; window units to first floors

“Hiab” is the genericised brand name (Hiab Cargotec, Finland) for a truck-mounted vehicle-loading crane. The plant category is the same as a knuckle-boom or articulating loader crane. Mobile slewing and non-slewing cranes are separate plant categories with their own licence classes.

What’s in scope (typical engagement)

Mobilisation: travel from yard, on-site set-up including outrigger deployment and ground pad placement
Pre-lift: load weight estimation, rigging selection, exclusion zone marking, ground bearing confirmation
The lift: hook-up by the operator or accompanying dogger, boom out, set load, dis-rig
Repeat cycles within the booked hire window
Operator’s SWMS for the lift activity, integrated with the builder’s site SWMS

What’s out of scope (often confused)

Rigging design for engineered lifts: multi-crane lifts, unbalanced or fragile loads, lifts inside enclosures need a separate engineered lift study
Trades-side load preparation: pallet banding, truss strap-up, beam sling points are the supplying trade’s job
Permit acquisition: lane closures, council crane permits, overhead-line clearance permits from the network operator are the builder’s job
Site traffic control and dilapidation surveys of neighbouring properties: builder organises before the crane arrives

Engagement basics

Licensing: high risk work classes

Schedule 3 of the model WHS Regulations 2011 lists the high risk work licence (HRWL) classes for cranes. The classes that matter on a residential site:

Class	Plant	Threshold
CV	Vehicle-loading crane (hiab, truck-mounted articulating crane)	10 metre-tonnes capacity and above. Below 10 mt no HRWL is required, but the PCBU must still verify operator competency. The CV class includes dogging for loading and unloading the truck itself.
CN	Non-slewing mobile crane (boom or jib that cannot slew)	Above 3 t capacity
C2	Slewing mobile crane	Up to 20 t capacity
C6	Slewing mobile crane	Up to 60 t capacity
C1	Slewing mobile crane	Up to 100 t capacity
C0	Slewing mobile crane	Over 100 t capacity (open class)
DG	Dogger (load slinging, directing operator from outside the cab)	Separate licence; required where an offsider is hooking and directing loads not covered by the CV’s built-in dogging scope
RB	Basic rigging	Required where rigging design or use exceeds the dogger’s scope

Capacity for a hiab is load × radius (metre-tonnes), not the truck’s GVM. A small ute-mounted unit can be under 10 mt and exempt from CV licensing; a typical builder’s truck hiab is well over. Verify the data plate against the operator’s licence class. HRWLs are nationally portable and renewed every 5 years (verified 2026-05-13, Safe Work Australia).

Heavy-vehicle driver licence

The CV HRWL covers operating the crane, not driving the truck. The driver also needs the heavy-vehicle class under the Heavy Vehicle National Law: typically HR (Heavy Rigid) for a two-axle truck over 8 t GVM (verified 2026-05-13). For most residential hiabs the driver and crane operator are the same person holding both.

HRCW and SWMS

Operating powered mobile plant on a construction site is high risk construction work under regulation 291 of the model WHS Regulations. A SWMS is mandatory before lifting: the operator’s SWMS for the lift, integrated with the head contractor’s site SWMS.

If the lift is near energised overhead electrical lines, the WHS Regulations require minimum clearance distances and (by voltage) a permit from the network operator plus a safety observer.

Lift plan

Anything beyond a single-pick onto a clear pad needs a documented lift plan. The references are AS 2550.1:2011 (safe use) and AS 1418.11:2017 (plant). A lift plan covers:

Load weight, dimensions, lift points (supplier or engineer signed off)
Radius at each pick and set point, checked against the crane’s load chart
Ground bearing at outrigger positions; pad size and material
Rigging (slings, shackles, spreader bar) and rated capacity
Exclusion zone radius (typically 1.5× load lift height, barricaded)
Sequence: who hooks, signals, watches the radius, clears the zone
Wind cut-off (per plant manual; routinely 32 km/h gusts on residential lifts)
Emergency procedures: load drop, mechanical failure, structure contact

On a roof truss lift the roof framing supplier nominates lift points and a strap-up spec; the plan integrates this with site geometry.

Dogger vs spotter

Not interchangeable terms.

Dogger (DG HRWL, or the dogging scope inside a CV licence): selects rigging, sights loads, directs the operator. Mandatory on blind lifts where the operator can’t see the load.
Spotter: a competent observer who watches for hazards (overhead lines, pedestrians, services) and stops work. Not a licensed role.

For most truss and beam lifts the CV-licensed operator dogs their own load. Where the set-down point is out of sight, a separately licensed DG dogger is required.

Insurance the operator should carry

Public Liability: $20m minimum given lift exposure ($10m is undercooked)
Workers Compensation: mandatory for any employee
Plant and equipment insurance: the operator’s own crane cover
Contract Works (the builder’s): covers the load in transit. Confirm where the supplier’s transit cover ends and the builder’s contract works begins.

Require Certificates of Currency for PL and Workers Comp before site access, plus a copy of the operator’s HRWL.

Pricing basis

Crane hire is wet hire (machine plus operator), per hour with a minimum.

Item	Typical 2026 norm
Wet-hire rate, mid-size hiab (CV)	$180-250/hr ex-GST
Minimum hire	3-4 hours or half-day
Travel	Portal rate or fixed mobilisation fee; confirm if travel counts against minimum
Standby (site not ready)	Full hourly rate
Mobile slewing crane (CN/C2)	$250-400/hr ex-GST plus float fee
Float fee, larger mobile crane	$400-1,200 one-way, distance and class dependent
After-hours / weekend	1.5× to 2× weekday rate

Confirm whether dogging is in the rate, when the clock starts (booking time or first lift), and cancellation terms (typically 24-hour notice or full minimum).

Tolerances and acceptance

Crane work is binary: either the load is set within an acceptable tolerance and the area is left intact, or it’s not.

Item	Standard
Load set position	Within rigging adjustment of design location; nominally +/- 25 mm for a truss or beam on a marked bearing point
Outrigger ground bearing	No subsidence, no plate deflection. If ground was uncertain, the lift plan should have specified pad timbers or steel plates.
Lift damage	No contact between boom, load, or rigging and the building, eaves, scaffold, or neighbouring property. Any contact is a notifiable issue.
Recovery	No debris or damage to driveway, lawn, or paving from outrigger pads. Photograph outrigger zones before and after.

Common defects to look for

Ground bearing not pre-verified: outrigger drops into soft ground, lift halted. Builder confirms ground capacity and pad spec before booking.
Radius outside the load chart: a 5 t pick at 4 m radius is not a 5 t pick at 8 m. The operator checks; the builder should understand the chart.
Exclusion zone broken: trades return to the lift footprint before the load is set. Builder enforces, not the operator.
Overhead service not cleared: NBN, street lighting, or HV mains within the boom sweep. Network operator clearance permits take days; book early.
Strap-up not done before crane arrives: trusses banded but lifting straps not fitted; crane sits on the clock. Specify in the order to the supplier.
Unlicensed offsider dogging a blind lift: a labourer “guiding it down” on a load the operator can’t see is a compliance breach. DG-licensed dogger required.
Wind cut-off ignored: stop work if the lift plan’s wind threshold is exceeded; sway is not a finesse problem.

Subbie quote pack, what should be in it

Scope: picks, expected load weights, peak radius, set-down points
Plant: crane class (CV, CN, C2, etc.), make/model, capacity, boom reach
HRWL evidence: operator’s licence number and class; dogger’s licence if separate
Heavy-vehicle licence: truck driver’s class
SWMS: prepared and supplied before site access
Lift plan: required for multi-pick or constrained lifts; nominate who prepares
Insurance: PL $20m min, Workers Comp, plant and equipment
Pricing: hourly rate, minimum, travel, standby, after-hours, dogging, float fee
Site conditions assumed: ground bearing, access width, overhead clearances, exclusion zone enforced by builder
Cancellation: notice period and minimum charge if cancelled inside the window
Programme: arrival window, on-site duration, dependencies (strap-up, scaffold, permit)

Builders use it as the quote template; operators win bookings by supplying all of it without being asked.
