Mezzanine Floor Installation SWMS
Safe Work Method Statement covering the key hazards and control measures for mezzanine floor installation.
SWMS variants reference your stateβs WHS legislation. Instant download after payment.
Mezzanine floor installation is a high-risk steel construction activity involving the erection of an elevated structural platform within an existing building envelope, typically combining bolted column-to-baseplate connections, primary and secondary beam framing, bar grating or steel decking, and edge protection systems. The work routinely occurs at heights between 2.4m and 6m above the finished floor level and requires coordinated lifts of structural members weighing several hundred kilograms using forklifts, telehandlers or mobile cranes inside live warehouse or industrial environments. Under WHS Regulation 2025, this scope is classified as High Risk Construction Work (HRCW) because workers can fall more than 2 metres and structural steel erection is undertaken β both independent triggers under Schedule 1. A documented Safe Work Method Statement is mandatory before work commences, must be developed in consultation with workers, and must be readily accessible at the workplace for the duration of the activity. This SWMS addresses the specific hazards of mezzanine erection sequencing, temporary stability, fall prevention and load handling in confined indoor footprints.
Hazards identified
7 hazards covered, sorted by priority.
Fatal multi-system trauma or permanent spinal injury from uncontrolled fall exceeding 2 metres onto concrete slab below
Crush fatalities to erectors and ground workers from progressive structural collapse of unbraced columns and beams
Severe head injury, fractures or fatality to ground-level personnel from objects falling from height during fit-out
Crush injuries to operator and spotters plus structural damage from overturned plant carrying suspended steel members
Amputation, degloving or crush fractures to fingers and hands when steel members swing or settle during landing
Acute lumbar disc injury and chronic musculoskeletal disorder from repeated awkward lifts above shoulder height
Structural fire, smoke inhalation injuries and significant property loss in live operational facility with stored goods
Control measures
Hierarchy-of-controls order: elimination β substitution β isolation β engineering β administrative β PPE.
- 1Elimination β Specify pre-fabricated modular mezzanine systems with factory-drilled connections to eliminate on-site cutting, welding and bolt-hole rework at height wherever the structural design permits.
- 2Elimination β Complete maximum sub-assembly of frames, handrails and stair stringers at ground level before lifting into final position to remove work-at-height tasks.
- 3Substitution β Replace site welding of cleats and connections with engineered high-strength bolted connections to substitute hot work risk with mechanical fastening verified by torque wrench.
- 4Substitution β Use mechanical lifting jaws and beam clamps instead of synthetic slings choked around painted steel to reduce slip-out risk during landing.
- 5Engineering β Install perimeter scaffold or mobile elevating work platforms with guardrails compliant with AS/NZS 1576 before commencing any decking work above 2 metres.
- 6Engineering β Erect catch decks, debris nets or exclusion barricades at full deck perimeter to capture dropped fasteners and prevent objects reaching personnel below.
- 7Administrative β Sequence the erection plan so columns, primary beams and permanent bracing are torqued and engineer-certified before any worker accesses the elevated frame.
- 8Administrative β Conduct documented pre-start toolbox talk against this SWMS daily, with sign-on register, exclusion zone briefing and emergency rescue drill confirmation.
- 9PPE β Issue and enforce full body harnesses to AS/NZS 1891.1 with twin-tail energy-absorbing lanyards anchored to certified 15kN points whenever guardrails are incomplete.
- 10PPE β Provide hard hats with chin straps, cut-resistant gloves, safety glasses, steel-capped boots and high-visibility clothing as the final layer beneath higher-order controls.
Applicable Codes of Practice
Sets the structural geometry, guardrail height, kickplate and stair pitch requirements that the completed mezzanine and its access must satisfy on handover.
Mandates anchorage rating, harness inspection, lanyard configuration and rescue planning whenever workers are exposed to fall risk during frame erection.
Triggers the SWMS preparation, consultation, review and site availability duties for High Risk Construction Work including work above 2 metres and structural steel erection.
Governs bolt grade selection, connection torque, weld procedures and erection tolerances that the installation crew and verifier must achieve at every connection.
High-Risk Construction Work triggered
Erectors stand on primary beams, partial decking and EWPs at 2.4m to 6m to land secondary members and install handrails before edge protection is complete.
Partially erected columns and beams rely on temporary bracing, lacing and bolt-up sequencing to prevent progressive collapse before permanent bracing is torqued and certified.
PCBU must prepare the SWMS in consultation with workers, provide it before work starts, monitor compliance and retain it for the project; penalties for breach are substantial and indexed, with the current maximum following the prevailing WHS schedule.

Worked example
A four-person crew arrives at a distribution centre fit-out to install a 240 square metre storage mezzanine across two shifts. Before any lifting begins, the leading hand opens this SWMS on a tablet at the laydown area and walks the team through it line by line. The crew identifies that the eastern bay sits directly above an active pick aisle, so they apply the administrative control of relocating the exclusion zone and rescheduling that section for the warehouse night curfew. Reviewing the fall hazards row, they confirm two scissor lifts with current logbooks are available and that twin-tail lanyards rated to AS/NZS 1891.1 are issued, because perimeter handrail will not be installed until after the decking sequence. Each worker signs the SWMS register including the dogger and the forklift operator landing beams. During the shift, a beam is found to be twisted on delivery and cannot be lifted with the planned clamp; work stops, the leading hand annotates the SWMS with the substitution to a certified two-leg chain sling and re-briefs the crew before continuing. At handover the signed SWMS, the daily pre-start records and the engineer's bracing sign-off are filed with the principal contractor as evidence of consultation and compliance.
