Colorbond Fence Installation SWMS

Colorbond steel fence installation involves a sequence of construction tasks that each carry distinct WHS exposures: excavating post holes, mixing and placing concrete, lifting and positioning pre-coated steel posts and rails, handling thin-gauge Colorbond sheets in variable wind, on-site cutting with abrasive tools, and fitting gate hardware including self-closing hinges and drop bolts. The work is classified as construction work under WHS Regulation 2025 and triggers High Risk Construction Work criteria through manual handling of awkward sheet loads and exposure to sharp metal edges generated by cutting and trimming. A Safe Work Method Statement is mandatory before work commences under WHS Regulation 2025 r.299, must be developed in consultation with workers under r.47, kept available for inspection on site, and reviewed if controls fail or site conditions change. This SWMS documents the hazards, hierarchy-of-control measures, training prerequisites, and supervision arrangements required to lawfully deliver Colorbond fence installation on residential and commercial sites.

Hazards identified

7 hazards covered, sorted by priority.

Control measures

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

1. 1Elimination — Order panels pre-cut to surveyed lengths and pre-punched at the manufacturer to eliminate on-site abrasive cutting and burr generation wherever fence runs allow.
2. 2Elimination — Cease all sheet handling and stop work when sustained wind exceeds 35 km/h measured by on-site anemometer to remove wind-loading hazard entirely.
3. 3Substitution — Use ready-mix rapid-set post concrete in pre-measured bags instead of mixing aggregate and cement on site, reducing silica dust and manual lifting load.
4. 4Substitution — Replace angle grinder cutting with nibblers or aviation snips for trim cuts, eliminating hot particles, disc fragmentation risk and most edge burrs.
5. 5Engineering — Use Dial Before You Dig plans and a cable locator scan before any auger or post-hole excavation; hand-dig the top 300 mm in serviced zones.
6. 6Engineering — Two-person lift trolleys and panel carriers for sheets over 1.8 m; mechanical post-hole augers mounted on skid-steer for runs exceeding 20 posts.
7. 7Administrative — Daily pre-start using this SWMS, documented sign-on, wind monitoring schedule, and exclusion zones marked with bunting around active cutting and excavation work areas.
8. 8Administrative — Rotate cutting, digging and lifting tasks every 90 minutes and schedule heavy manual work in cooler periods to manage fatigue and musculoskeletal load.
9. 9PPE — Cut-resistant Level D gloves AS/NZS 2161.3 for all sheet handling, medium-impact safety glasses AS/NZS 1337.1 plus face shield during powered cutting.
10. 10PPE — Long-sleeve high-visibility clothing AS/NZS 4602.1, steel-cap boots AS/NZS 2210.3, P2 respirators AS/NZS 1716 during cutting, and nitrile gloves under leather when handling wet concrete.

Worked example

On a suburban duplex perimeter fencing job, the leading hand opens this SWMS at the 7:00 am pre-start brief on the nature strip with three installers present. Working through the hazard register, the crew identifies the day's three dominant risks: a forecast 30 km/h northerly building to 40 km/h after lunch, a Dial Before You Dig plan showing a Telstra conduit running 600 mm inside the front boundary, and 38 lineal metres of 1.8 m Colorbond sheet to install. The leading hand assigns the wind-monitoring anemometer to the apprentice with instruction to call a stop if gusts hit 35 km/h, marks the conduit zone with white paint for hand-digging the first 300 mm, and confirms the pre-punched panels arrived from the supplier so no on-site abrasive cutting is required except for two end trims. Each worker signs the SWMS sign-on sheet, including the labour-hire carpenter brought in for the gate hang. At 1:40 pm the anemometer reads sustained 36 km/h; the apprentice calls it, the crew tarps the remaining six panels against the stack, and the SWMS is annotated in the daily review section noting the stoppage, the time, and that work resumed at 3:15 pm once wind dropped. The annotated document is filed with the site records.
