Telecommunications Tower Erection SWMS

Telecommunications tower erection covers greenfield installation of monopole, lattice, and guyed structures typically ranging from 15 to 80 metres, including foundation interface checks, sectional assembly, crane-assisted lifting, guy-wire tensioning, and headframe / antenna mount installation. The work simultaneously triggers multiple high-risk construction work categories under WHS Regulation 2025 section 291 — work at height above two metres, structural erection of a telecommunications tower, and proximity to energised electrical and RF installations on collocation sites. Because the activity combines fall risk, suspended loads, dropped-object exposure, and non-ionising radiation from adjacent live carriers, a Safe Work Method Statement is mandatory before any worker steps on site under regulation 299. The SWMS must be prepared in consultation with riggers, dogmen, EWP operators, and the carrier RF safety officer, and must remain accessible at the worksite for the duration of the works. Failure to prepare, communicate, or follow the SWMS exposes the PCBU, principal contractor, and supervising person to category 1 or 2 offences under the WHS Act.

Control measures

Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.

1. 1Elimination — Pre-assemble headframe, antenna mounts, feeder cable trays, and lightning finial at ground level so high-level bolt-up time on the tower face is minimised or removed entirely.
2. 2Elimination — Schedule erection works only after the host carrier has confirmed in writing that collocated transmitters within RF exclusion zones are powered down or attenuated below RPS S-1 occupational limits.
3. 3Substitution — Use a knuckle-boom EWP or man-cage on the crane for headframe fit-out instead of free-climbing the lattice where site access and ground bearing permit safe machine deployment.
4. 4Substitution — Replace conventional shackle-and-pin rigging with engineered self-locking lifting clutches and tagged synthetic round slings rated and certified to AS 4497 for each tower section weight.
5. 5Engineering — Install a continuous fall-arrest rail or twin-tail lanyard cable system on the climbing face before any worker ascends, conforming to AS/NZS 1891.2 anchorage and structural attachment requirements.
6. 6Engineering — Establish a hard-barricaded crane exclusion zone equal to 1.5 × lift radius, with spotter-controlled access, drop-zone matting, and tool tethering on every item above 250 grams.
7. 7Administrative — Conduct a documented pre-start using this SWMS, the AS 2550.1 lift study, the RF safety briefing, and a verbal sign-on by every rigger, dogman, crane operator, and EWP operator.
8. 8Administrative — Operate a permit-to-climb system gated by a verified personal RF monitor reading, current high-risk work licences (RB/RI, CN/CV, WP), and a documented rescue-from-height plan with on-site rescue kit.
9. 9PPE — Issue full-body tower-rated harness to AS/NZS 1891.1, twin energy-absorbing lanyards, work-positioning belt, climbing helmet with chinstrap to AS/NZS 1801, and rated impact gloves.
10. 10PPE — Supply personal RF monitors set to ARPANSA RPS S-1 occupational thresholds, ANSI Z87.1 eye protection, and arc-rated long-sleeve clothing for any work within reach of carrier power feeds.

High-Risk Construction Work triggered

Worked example

On a greenfield 45-metre lattice tower build for a regional carrier rollout, the lead rigger opens the pre-start at 06:30 with the full crew — two climbers, a dogman, the crane operator, an EWP operator, and the site supervisor — gathered at the bonnet of the site ute with this SWMS printed and on screen. He walks the crew through hazard line by line: the fall-arrest rail must be tensioned before the first climber leaves the ground; the host carrier's RF power-down confirmation email is read aloud and stapled to the SWMS; the lift study for the three lattice sections and the headframe is cross-checked against the day's wind forecast of 28 km/h, which sits inside the 36 km/h shutdown trigger written into the controls. Each worker signs on, ticks their RB licence and harness inspection date, and clips a personal RF monitor to their chest strap. Mid-morning, the dogman notices the crane's offside outrigger pad is showing 40 mm of settlement into the decomposed granite pad — a hazard flagged in row 6 of this SWMS. Work stops, the supervisor pulls the SWMS, adds a hand-written amendment requiring 1.2 m × 1.2 m crane mats under both offside outriggers, re-briefs the crew, and every worker re-signs the amendment before the next lift proceeds.
