Writing a material handling method statement for large stone composite panels

Stone composite panels have reshaped commercial facades across Australian capitals, from the glass-and-stone towers rising above Brisbane's riverside to the boutique office blocks popping up in inner Melbourne. With panels often tipping 80 kilograms per square metre and arriving on stillages 3.6 metres long, a written handling method statement stops the job from running on guesswork. Site supervisors, crane operators and the trade crew all need to know exactly how a panel moves from truck to fixing before the first slinger touches a strap.

In Australia, that document is almost always written alongside a Safe Work Method Statement, the SWMS that state regulators such as SafeWork NSW and WorkSafe Victoria expect on any high-risk construction activity. Manual handling of large format cladding sits firmly in that high-risk bracket. A handling method statement complements the SWMS by covering the practical moves: where panels are stored, how they are flipped, which machine does the lifting, and who calls the signals.

Stone composite panels behave differently to aluminium cassette cladding. They are denser, more brittle at the edges, and they cannot be flexed to pop into a receiver track. That brittleness rewards planners who think about the journey of each panel before it leaves the crate. A well drafted statement also protects the visual finish, since a chipped corner or a scuff on the stone face means a factory remake and a hold-up on programme.

The Australian setting adds its own wrinkles. Summer heat on a Perth yard can push panel surface temperatures well above 50 degrees, which affects how adhesives cure and how workers grip the sheets. Coastal projects between Coffs Harbour and the Mornington Peninsula face salt-laden air that marks unprotected edges within days. Long haul distances from Brisbane to regional Queensland, or from Melbourne to a Pilbara mine camp, mean panels often travel for days before they reach the lay-down area, and the handling plan must reflect that.

Defining the panel, the project and the people involved

A clear method statement opens with the basics: panel type, dimensions, weight per sheet, and the total number of sheets for the project. For most Australian commercial jobs, large stone composite panels run 1200 mm wide, 2400 to 3600 mm long, and between 20 and 30 mm thick, weighing 60 to 120 kg each. The document should name the manufacturer, the fixing system, and the substrate, because handling rules shift between a rivet-fixed panel and a structural silicone glazed one.

The project envelope matters too. A 14-storey build above a busy laneway in Sydney's CBD demands a tighter crane plan than a single-storey warehouse on the outskirts of Geelong. Site footprint dictates whether a 20-tonne mobile crane can sit on a hardstand or whether a smaller telehandler does the lifting from inside the slab. Naming the principal contractor, the cladding subcontractor and the crane provider at the top of the document keeps accountability visible.

Finally, the people. The method statement lists the lift director, the dogger or rigger, the slingers, the machine operator and the fixers who receive the panel at the building line. Australian sites often rely on experienced operators who have learned the craft on coastal or remote projects, and that experience is captured in the document so a less seasoned crew member knows who is calling the shot on the day.

Risk identification and control measures

Manual handling tops the risk register. Panels over 25 kg should not be moved by a single worker, and sheets above 50 kg almost always need mechanical assistance. The method statement lists the controls: two-person lifts for short carries off the stillage, vacuum lifters for horizontal flips, and crane picks for the final movement from ground to fixing point. Each control is paired with a residual risk rating so reviewers can see what is still open.

Environmental risks are equally important in Australia. Working at 35 degrees in Adelaide's late afternoon sun pushes hydration breaks into the schedule, and the statement should call them out rather than leave them to chance. Wind speed thresholds for crane lifts are set conservatively, usually around 25 km/h for panel work, and the document should give the supervisor clear authority to halt the lift if a gust comes through. Edge protection, exclusion zones and pedestrian diversions are also captured here, particularly on tight inner-city sites where a dropped panel would have nowhere to land safely.

Drop zones deserve their own paragraph. A panel dropped from level six carries enough energy to crush a concrete slab, and the statement must show the exclusion zone in plan view, not as a vague line of text. Truck drivers delivering panels to the loading bay are included in the exclusion zone planning, which is why a banksman is named and a radio channel is agreed before the first sheet is unstrapped.

Lifting gear, attachments and cranage

The mechanical heart of the method statement is the lifting chapter. Vacuum lifters, often with a four-cup array rated to 400 kg, are standard for stone composite sheets because they spread the load and avoid edge clamping. The statement names the vacuum unit, its last service date, the battery state on the day, and the spare unit kept on standby. Slings are usually avoided for stone-faced products because the textile can mark the surface, so the document specifies rigging beams and spreader bars that keep the panel flat during the lift.

For high-rise Australian builds, the tower crane does most of the work. The method statement confirms the crane's chart for the radius required, the planned panel weight including rigging, and any slewing restrictions near neighbouring towers or live traffic. Tag lines are mandatory and the document says how many, who holds them, and when they are attached. On smaller projects, a mini crawler crane or a telehandler with a personnel-rated basket may take over, and the controls around that swap are written down rather than left to improvisation.

Operators must hold the right tickets, and the statement names each one. Dogging, rigging and crane operation tickets issued under Australian qualification frameworks are listed, and photocopies are kept with the document on site. Where a vacuum lifter is used on the building line, the operator's competency record is attached so an auditor can see the chain of evidence in one place.

Delivery, storage and movement around site

Stone composite panels arrive on timber or steel stillages, often wrapped in a UV-stable film that the supplier expects to stay on until just before fixing. The method statement covers how the stillage is unloaded at the gate, where it is staged on the slab, and how it is protected overnight. In Brisbane or Darwin, where afternoon storms are reliable, panels stored on an open deck need tarps or a designated covered area, and the document should show which is used.

Just-in-time delivery is common on Australian CBD jobs because lay-down space is at a premium. The statement lists the delivery window, the route through site, the waiting point for trucks, and the contact at the gate. Where a panel has travelled from a Sydney factory to a Darwin site, the planning for storage extends to acclimatisation, because a cold panel pulled into a 32-degree shed can sweat and leave marks on the stone face.

Movement from the lay-down to the fixing point is usually the most labour-heavy part of the job. The method statement breaks it down: vacuum lift off the stillage, tilt to vertical on a purpose-built A-frame, secure with the factory edge protection, then lift to the crane hook. Each step has an image or sketch in good practice, and the text confirms that no step is skipped, even when programme pressure mounts at the end of a level.

People, training and on-site communication

A method statement only works if the crew on the day understands it. Australian sites typically run a pre-start toolbox talk before cladding lifts begin, and the handling statement is read through, signed off, and filed. New starters, including labour-hire fixers who may have come off a different trade the week before, are walked through the document by the leading hand before they touch a panel.

Communication protocols matter because panels travel through several hands. The lift director on the ground uses a UHF radio on a dedicated channel, the dogger repeats every instruction back, and the rigger at the panel confirms the attachment is set before the crane takes the weight. The statement names the channel and the call signs so a casual visitor does not accidentally chatter over the lift sequence.

Crew welfare is part of safe handling. Heat management, hydration stations, scheduled breaks and rotation of heavier tasks all sit in the document because tired workers mishandle panels. Even short, well-structured mental breaks between heavy lifts do more for site safety than most supervisors expect, and leading hands who schedule them deliberately often report fewer near-misses on the second half of a long shift. A brief glance at something low-stakes during the break — such as a quick overview of online casino promotions — is enough to reset attention before the next vacuum pick.

Documentation, monitoring and continuous improvement

Once the method statement is signed, it is not filed and forgotten. The lift director records each panel moved, the time, the crew, and any snag encountered. A small damage log is kept so the project manager can chase replacement sheets before the next delivery. State-based regulators can ask for these records during a routine inspection, and a clean set of notes often shortens the visit.

Review points are built in. After the first ten panels are fixed, the leading hand and the crane operator sit down and compare the statement with what actually happened. If vacuum lift times were longer than planned, or if a tag line snagged on a scaffold fitting, the document is updated before the next level starts. That feedback loop turns a static sheet of paper into a working tool, and it gives the next crew on site, whether they are in Parramatta or Perth, a head start on a safer, smoother set.

The thermal break insights behind metal frame glazing pair closely with stone composite detailing at window heads, which is why experienced cladding teams treat the handling method statement and the interface drawings as one continuous document rather than separate files.
