Lawn Install (Turf Laying) SWMS

Lawn installation covers preparation of subgrade soil, screeding and levelling, delivery and roll-out of instant turf slabs or broadcasting of seed, edge cutting against paths and garden beds, initial irrigation and starter fertiliser application. Although often perceived as low-risk soft landscaping, the work involves sustained manual handling of saturated turf rolls weighing 15–25 kg each, prolonged kneeling and stooped postures, exposure to nitrogen and phosphorus fertilisers, and operation of powered edging and rotary hoes. Under WHS Regulation 2025 the PCBU must prepare a Safe Work Method Statement before any work that involves hazardous manual tasks performed repetitively, exposure to scheduled chemicals, or use of powered cutting equipment on a construction site. A documented SWMS ensures hazards are identified, the hierarchy of control is applied, workers are consulted under section 47, and the statement is available for inspection by the regulator for the duration of the work.

Hazards identified

7 hazards covered, sorted by priority.

Control measures

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

1. 1Elimination — Specify pre-cut big-roll turf delivered by mechanical roll-out machine for areas over 200 m² to remove repetitive manual handling of individual slabs entirely.
2. 2Elimination — Engage Dial Before You Dig and conduct cable/pipe locator sweep before any rotary hoeing to remove underground strike risk at source.
3. 3Substitution — Replace granular high-ammonia starter fertiliser with coated slow-release prill or liquid wetter-fertiliser blend to reduce dust inhalation and dermal absorption exposure.
4. 4Substitution — Use battery-powered edger with enclosed blade guard instead of petrol whipper-snipper to reduce noise, exhaust and projectile risk during perimeter trimming.
5. 5Engineering — Deploy turf trolleys, pallet jacks and conveyor roll-out frames so workers slide rather than lift slabs from pallet to laying face.
6. 6Engineering — Install temporary shade structures and provide chilled potable water stations within 50 m of the work face during forecast temperatures above 30°C.
7. 7Administrative — Rotate workers between laying, edging and watering tasks at maximum 45-minute intervals and schedule heavy lifting before 10am in summer per the heat stress procedure.
8. 8Administrative — Conduct documented pre-start SWMS sign-on identifying the day's chemicals, SDS location, first aider, and emergency eyewash position before fertiliser is opened.
9. 9PPE — Issue knee pads compliant with the relevant impact protection standard, cut-resistant gloves for edging, and AS/NZS 1067 sunglasses plus broad-brim hat with SPF50+ sunscreen.
10. 10PPE — Provide P2 respirators, chemical splash goggles and nitrile gloves during fertiliser handling, with laundered long-sleeve hi-vis to prevent dermal contact and UV exposure.

Applicable Codes of Practice

High-Risk Construction Work triggered

Worked example

On a new townhouse handover in an outer suburban estate, a two-person landscaping crew arrives to lay 180 m² of instant buffalo turf across four front yards. Before any pallet is broken open, the leading hand opens the Lawn Install SWMS on a tablet at the tailgate and walks the offsider through the seven hazards. They identify that yesterday's rain has left the subgrade saturated, elevating the slip and manual handling risk, and the forecast shows 34°C by 1pm, triggering the heat stress administrative control. They confirm Dial Before You Dig plans are on site, locate the irrigation manifold, and mark it with paint. The SDS for the starter fertiliser is pulled up, P2 masks and nitrile gloves are laid out, and the eyewash bottle is moved to the ute tray within arm's reach. Both workers sign the SWMS sign-on sheet acknowledging the controls, including the 45-minute task rotation and the decision to use the powered roll-out trolley rather than hand-carrying slabs. Mid-morning, the offsider reports knee soreness; the leading hand pauses work, reviews the SWMS kneeling control, swaps him onto edging duties and fits fresh gel knee pads before resuming. The amended rotation is noted on the SWMS so the change is captured in the live document and available if the regulator attends site.
