Factory and Warehouse Demolition in Victoria: What’s Different

If you’ve ever sold off an old industrial holding in Melbourne’s inner-west, walked an empty manufacturing plant in Dandenong with a developer in tow, or stood on the slab of a closed-down food-processing facility in Brooklyn wondering what it would take to clear it — you’ve already felt the difference.

A factory or warehouse demolition is not a bigger version of a residential demolition. It’s a different job, run by a different category of plant, against a different regulatory backdrop, with a different cost structure and a different risk profile. Get that mental model right at the quote stage and the project runs cleanly. Get it wrong and you spend three months and six figures untangling the parts that should have been scoped on day one.

As a fully licensed Melbourne demolition contractor with our own Class B (non-friable) asbestos removal capability, we run industrial demolition and site-clearance projects every month across metropolitan Melbourne and regional Victoria — old warehouses being cleared for townhouse subdivisions in Yarraville and Footscray, factory complexes coming down for new logistics estates in Truganina and Laverton North, mid-century manufacturing plants making way for medium-density residential in Coburg and Brunswick, and end-of-life industrial assets being demolished in place at Dandenong South and Hallam.

This guide is the plain-English version of what genuinely changes when you move from a single-storey weatherboard in Reservoir to a 6,000 m² tilt-panel warehouse in Truganina. We’re not going to rehash the bits that look the same as residential — your Section 29A, your asset protection, your basic permit stack already lives in our other guides. We’re going to walk through the seven things that are fundamentally different about industrial demolition in Victoria in 2026 and the practical implications that follow from each.

Quick answer: Factory and warehouse demolition in Victoria differs from residential demolition in seven structural ways — scale and plant (20–90 tonne high-reach excavators, hydraulic shears, on-site crushing); building typology (tilt-panel concrete, portal-frame steel, “Super Six” asbestos-cement roofing, structural slabs); asbestos at industrial volumes (hundreds to thousands of square metres of non-friable ACM, with friable hot spots in lagging, gaskets and switchboards); process plant and trade-services decommissioning (refrigerants, fuel and chemical storage, transformers, compressed air, racking); contaminated land (hydrocarbons, heavy metals, PFAS, asbestos-impacted fill — common across Melbourne’s industrial heritage suburbs); a shifted WorkSafe high-risk-construction-work profile (working at height on industrial roofs, structural steel cutting, mobile plant in tight envelopes); and an EPA waste regime that bites harder at scale ($167.90 per tonne metropolitan levy on potentially thousands of tonnes, Waste Tracker for every load of priority waste, GED exposure at company level). Each one moves the cost, the timeline and the compliance pack. None of them can be bolted on after the fact.

Why “Bigger House” Is the Wrong Mental Model

There’s a comforting version of industrial demolition that goes: it’s the same as residential, just with a bigger excavator. Roll a 30-tonne machine onto a slab, take the walls down faster, load more trucks, finish in a month instead of a fortnight.

That mental model is wrong in almost every direction that matters. Industrial demolition is fundamentally different because:

The structures themselves don’t behave like houses. A reinforced-concrete tilt-panel wall doesn’t fall the way a brick veneer falls. A portal-frame steel shed doesn’t release loads the way a timber-framed cottage does. Structural slabs designed for 20-tonne forklift wheel loads don’t break out the way a 100mm residential slab does.
The asbestos quantity is on a different order of magnitude. A 1970s tilt-panel warehouse can carry 2,000–4,000 m² of Super Six roofing alone — more non-friable asbestos in one building than fifty residential properties combined.
The soil underneath has a contamination history. Factories spilled solvents. Warehouses stored fuel. Manufacturing sites used heavy metals. Many of the inner-west and outer-south sites being demolished in 2026 sit on land that the Environment Protection Act 2017 expects you to investigate before you build on it.
The plant inside the building has to be decommissioned before the demolition can start. Refrigeration systems contain regulated gases. Transformers may contain PCBs. Compressed-air receivers hold stored energy. Fuel tanks, both above and below ground, are a category of their own.
The regulatory framework doesn’t shift, but its bite scales with the job. WorkSafe Victoria still runs the same OHS Act 2004, OHS Regulations 2017 and Compliance Code: Demolition (Edition 2, 2019) — but the high-risk-construction-work catalogue gets ticked harder. EPA Victoria still runs the same Environment Protection Act 2017 and Regulations 2021 — but the General Environmental Duty exposure climbs with the waste volumes, the dust footprint and the contamination potential.

That’s the frame. Now let’s walk through the seven structural differences in detail.

Difference 1: Scale and Plant — Why the Excavator Gets Bigger and Smarter

A standard suburban Melbourne demolition runs on a 5–14 tonne tracked excavator with a hot-swappable bucket, grapple, pulveriser and hydraulic hammer. That’s the right machine for a 200 m² weatherboard or a 250 m² brick veneer. Roll it onto a 6,000 m² distribution warehouse and you’d still be there at Christmas.

Industrial demolition runs on a different class of plant — and the choice between machine sizes is one of the early scoping decisions that drives the timeline, the dust profile, the access plan, and the cost.

The Standard Industrial Demolition Fleet

A typical Melbourne factory or warehouse demolition deploys some combination of:

20–30 tonne tracked excavator as the workhorse for tilt-panel pulverising, structural steel cutting (with shears) and slab break-out
40–50 tonne tracked excavator for larger tilt-panels, primary structural steel and high-volume loading
High-reach excavator (60–90 tonne machine, 28–40 metre boom) for multi-storey factories, silos, mass-concrete structures and any work above 12 metres that can’t safely be done from a platform
Hydraulic shear attachment rated for 50–150mm structural steel — the right tool for portal frames, mezzanine racking, RHS columns and roof purlins
Concrete pulveriser for tilt-panels and reinforced columns, separating rebar from concrete as it works
Hydraulic hammer (breaker) for industrial-grade slabs (typically 150–300mm thick, sometimes 500mm+ in plant rooms and machine bases)
Sorting grab for the post-demolition segregation phase, picking clean concrete, clean steel, treated timber and mixed waste into separate loads
Wheel loader (3–7 tonne bucket) for moving processed material on site and feeding the crusher
Mobile concrete crusher — on larger jobs, processing clean concrete into recycled aggregate on site instead of trucking it out raw
Dust suppression unit — vehicle-mounted water cannons capable of throwing a fine mist 50+ metres, running continuously through demolition shifts

That fleet is more expensive to mobilise than a single residential excavator and trailer — but it also processes material at 10–30x the rate. On a well-scoped industrial job, the economics work because the plant is bigger, not in spite of it.

Why On-Site Crushing Matters at Industrial Scale

This is the lever most clients don’t price properly until they see the waste-stream maths.

A standard residential demolition produces 80–120 tonnes of mixed C&D waste. An industrial demolition routinely produces 2,000–8,000 tonnes — sometimes more on multi-building sites. At the 2025–26 metropolitan waste levy of $167.90 per tonne, the disposal line alone on a 4,000-tonne raw-load job is $671,600 before tipping fees, transport or any priority-waste surcharges.

Now run the same job through an on-site crusher. Clean concrete and brick — typically 60–80% of the waste stream by weight — gets processed into recycled aggregate (often called RCA in the trade) on site, sold or used as fill for the new build, and never crosses a weighbridge as waste. The remaining 20–40% — soil, residual asbestos-cleared rubble, mixed waste — goes to landfill at full levy.

The arithmetic on a typical 4,000-tonne tilt-panel warehouse demolition with on-site crushing looks something like:

Recycled aggregate (2,800 t at ~$10–$15/t recovery value): material avoids levy and tipping, often generates revenue
Steel scrap (200–400 t typically): sold to scrap recovery, generates revenue
Genuine landfill waste (800–1,000 t): pays the full levy and tipping
Asbestos waste (highly variable, treated separately under EPA’s reportable-priority-waste framework — see below)

The same job done without on-site crushing — every load leaving site to a transfer station as mixed waste — easily costs $300,000–$500,000 more in levy and tipping alone. That’s the line item where industrial demolitions go right or wrong, and it’s why a properly equipped Melbourne demolition contractor will scope the crusher into the methodology from day one rather than treat it as a “nice to have.”

The full waste-side framework sits in our EPA Victoria Construction and Demolition Waste Rules 2026 guide. The point for industrial demolition is that recycling isn’t a feel-good extra at this scale — it’s the financial backbone of the job.

Difference 2: Building Typology — Why Tilt-Panels and Portal Frames Don’t Demolish Like Houses

Most Melbourne factories and warehouses fall into one of four structural families, each with its own demolition methodology. Read the wrong methodology against the building and you either spend twice as much on plant, twice as long on site, or you create avoidable risk.

Type A: Old Brick and Sawtooth-Roof Mills (Pre-1950)

These are Melbourne’s inner-suburban industrial heritage — multi-storey brick warehouses in Collingwood, Fitzroy, Brunswick East, Cremorne, Yarraville, South Melbourne, North Melbourne and Footscray. Load-bearing brick perimeter walls, internal cast-iron or steel columns, timber floor structures, sawtooth roofs framed in timber or light steel, often with substantial timber strip flooring on heavy joists.

The demolition methodology looks closer to a heritage residential job than to a modern industrial one — careful structural sequencing, manual soft strip of recoverable timber and ironwork, brick walls taken down in courses with a pulveriser, internal columns lifted out with the excavator working from a stable platform. Many of these buildings are inside a Heritage Overlay (see Council Demolition Permits in Melbourne: A Suburb-by-Suburb Overview), which can convert a “warehouse demolition” into a “facade-retention demolition with engineered temporary works” — a substantially different cost and timeline picture covered in Partial Demolition: When Removing Half a House Makes Sense in Melbourne and Soft Strip vs Hard Demolition: Choosing the Right Method.

The asbestos picture in pre-1950 mills is often friable-leaning — pipe lagging on old steam systems, deteriorated cement-board linings, pre-existing fire-damage histories — and may push the job into Class A territory. We hold Class B and partner with Class A specialists where required.

Type B: Mid-Century Steel-Framed Factories With Super Six Roofs (1950–1985)

This is the dominant industrial typology across Melbourne’s mid-century manufacturing belt — Tottenham, Brooklyn, Sunshine, West Footscray, Spotswood, Williamstown, Coburg North, Preston East, Reservoir, Thomastown, Heidelberg West, Box Hill North, Notting Hill, Clayton, Springvale, Moorabbin, Cheltenham, Braeside, Tullamarine, Campbellfield, Broadmeadows and a substantial slice of Dandenong South.

The construction language is consistent:

Steel portal frames or RHS column-and-truss systems, often unpainted or partially painted
Brick or rendered-block perimeter walls to about 3 metres, with steel sheeting above
Asbestos-cement corrugated roofing — “Super Six,” “Fibrolite,” “Hardiflex” and various trade names — across the roof and often the upper walls
Asbestos-cement eaves, downpipes, flashings and gutter linings
Loading-dock canopies and lean-to additions with the same materials
Internal mezzanines of timber, steel deck or composite construction
Heavy reinforced-concrete slabs with strip footings and pad footings
Internal block partition walls, often with asbestos cement linings on the upper sections

These buildings demolish in a very specific sequence: Class B asbestos roof removal first, then portal frame deconstruction (typically shear-cut at the column bases, lowered controllably), then masonry walls pulverised, then slab break-out and loading. Trying to short-circuit that sequence — pushing the portals over with the asbestos roof still attached, for instance — is how a Class B job becomes a Class A contamination event in 90 seconds.

The asbestos quantity on a Type B building is typically the largest single line item on the quote. We’ll come back to that.

Type C: Modern Tilt-Panel Concrete Warehouses (1985–Present)

The post-1985 industrial estate look — tilt-up reinforced-concrete perimeter panels (typically 150–200mm thick, 7–9 metres tall), steel portal-frame roof structure, profiled steel roof sheeting, large powered roller doors, polished or sealed concrete slab inside. The dominant typology across the outer-west growth corridor (Truganina, Derrimut, Laverton North, Altona North, West Footscray infill estates), the outer-south (Dandenong South, Hallam, Lyndhurst), the outer-north (Somerton, Campbellfield, Epping, Thomastown), the east (Bayswater, Kilsyth, Knoxfield, Scoresby) and major regional industrial precincts in Geelong (North Shore, Norlane), Ballarat (Wendouree, Delacombe) and Bendigo (East Bendigo).

Tilt-panel demolition is a methodology of its own:

Strip-out any fitout — partitions, racking, mezzanines, services — first (see Internal Strip-Outs in Melbourne: A Guide for Commercial Tenants for the strip-out framework, even on owner-occupied buildings)
Cut the portal-frame roof structure with hydraulic shears, lowering sections in sequence with the excavator boom
Free the tilt-panels from their roof-tie connection and slab footings — each panel is now a free-standing concrete wall, kept stable only by gravity and the temporary support system
Lay panels down progressively using a combination of the excavator and pre-engineered tipping sequences — panels are not “pushed over” uncontrolled, they’re rotated about the slab edge with engineered pivot points and propped sequencing
Pulverise the laid-down panels into rubble suitable for crushing
Break out the slab and footings with hydraulic hammers and pulverisers

The asbestos picture in a true post-1985 tilt-panel is usually minimal — the 31 December 2003 Australian asbestos ban affected new use, but tilt-panel construction itself was largely past asbestos by the mid-1980s. The exceptions: vinyl floor tiles in older site offices, asbestos cement on lean-tos and extensions added to earlier-era buildings, and asbestos backing in switchboards and electrical equipment that was salvaged from older sites. Treat the survey, not the construction date, as the source of truth.

Type D: Heavy-Industrial and Process-Plant Structures

Foundries, food-processing plants, cold stores, chemical plants, power-generation infrastructure, silos, hoppers, conveyor towers, and large mass-concrete structures (former concrete batch plants, asphalt plants, fuel depots). These sit at the top of the industrial demolition complexity ladder and almost always require:

Specialist process-plant decommissioning before any structural demolition can begin (see Difference 4 below)
Pre-tensioned or post-tensioned concrete assessment — these structures store energy in the tendons and cannot be demolished by the same methods as conventional reinforced concrete (the WorkSafe Compliance Code: Demolition (Edition 2, 2019) calls these out specifically)
Confined-space protocols for silo, tank and vessel internals
Hot-works permits and licensed oxy-fuel cutting on structural steel where shears can’t reach
Contaminated-land assessment that often pre-dates the demolition methodology — at some sites, the demolition cannot proceed until an EPA-style Phase 2 Environmental Site Assessment has been completed and an environmental auditor is in the loop

These are not jobs for general demolition crews. They’re scoped, plant-resourced and priced by the project, not by the square metre.

Difference 3: Asbestos at Industrial Volumes — Why Class B Capability In-House Matters More Here

This is the difference that catches the most clients out, and the one that does the most damage when it’s mispriced.

The Industrial Asbestos Footprint

Melbourne factories and warehouses built between roughly 1945 and the late 1980s carry non-friable asbestos in genuinely industrial quantities. Walk an empty 4,000 m² Brooklyn or Tottenham warehouse from the 1970s and you’ll typically find:

3,500–4,200 m² of Super Six asbestos-cement roof sheeting (the roof is essentially all ACM)
400–800 m² of asbestos-cement wall sheeting on the upper walls and gables
200–500 m² of asbestos-cement eaves, soffits, gutter linings and downpipes
50–200 m² of vinyl floor tiles and bituminous adhesive in site offices, lunchrooms and amenities — often the worst-disturbed area on the site by the time we arrive
Asbestos pipe lagging on hot-water lines, steam systems, process piping and boiler insulation (frequently friable — Class A scope)
Asbestos-millboard behind boiler doors, around old furnaces and inside flue housings (often friable)
Asbestos gaskets, packing and rope seals on pumps, valves, flanges and process equipment
Asbestos backing boards behind switchboards, distribution boards and motor control centres
Asbestos cement underlay beneath corrugated iron roofs on later additions
Sprayed limpet insulation — relatively rare in Victorian residential but found in some 1960s–70s commercial and industrial buildings, particularly around structural steelwork for fire rating. Always friable.

The total non-friable asbestos quantity on a single mid-century warehouse can run 5,000–10,000 m². Compare that to a typical Melbourne weatherboard’s 80–200 m² of ACM and the scale shift is obvious. We covered the residential picture in Asbestos in 1950s–1980s Melbourne Homes: What’s Likely Hiding; commercial and industrial buildings of the same era show the same materials in roughly 20–50x the volume.

Why In-House Class B Capability Changes the Economics

A 4,000 m² Super Six roof removal job is a multi-week scope that requires:

WorkSafe Victoria notification at least 5 days before the licensed removal commences
A demolition-specific Safe Work Method Statement (SWMS) covering working at height on a degrading asbestos-cement substrate — one of the highest-fatality combinations on Australian construction sites
Edge-protection scaffolding or engineered access platforms the full perimeter of the roof
Wet methods, lap-by-lap removal, sheets lowered (not dropped) onto a clean ground stockpile
Double-bagging or wrap-wrapping in 200µm polythene for transport
EPA Waste Tracker logging for every load — asbestos is pre-classified reportable priority waste under Schedule 5 of the Environment Protection Regulations 2021, regardless of quantity
Transport by an A10a or A10b permission holder to an EPA-authorised landfill licensed to receive asbestos waste
Independent licensed assessor clearance of the roof void and the ground below before any further demolition commences

When that work is subcontracted out to a separate Class B removalist, the demolition contractor loses control of the sequencing, the documentation and the financial flow — and the client typically pays a co-ordination premium of 15–30% over what the same work costs when it’s run by a single licensed contractor under one insurance policy.

When the demolition contractor holds the Class B licence in-house (as we do), the asbestos sequencing, the WorkSafe notification, the Waste Tracker entries, the clearance booking and the structural demolition all run on the same critical path under the same project management. That’s the operational difference that makes industrial demolition affordable and properly compliant at the same time.

For the friable/non-friable distinction and the Class A vs Class B licence framework, see The Difference Between Friable and Non-Friable Asbestos in Demolition and Licensed Asbestos Removal Victoria: How to Verify Your Contractor.

The Friable Hot Spots Industrial Buildings Hide

Most industrial asbestos is bonded — the same Portland-cement matrix as residential cement sheet, just at industrial scale. The friable hot spots are where the project class can change:

Pipe and boiler lagging on hot-water, steam and process lines — often deteriorated, often disturbed by prior plant changeovers
Sprayed limpet insulation on structural steel — particularly in 1960s–70s buildings retrofitted with fire-rating after a code change
Millboard, asbestos rope and gaskets in furnace doors, boiler hatches and oven cavities
Fire-damaged areas — any historic fire on the site converts previously bonded ACM into friable material across an enlarged footprint
Mechanically degraded sheeting — Super Six roofs left exposed for decades develop matrix breakdown, particularly on weather-exposed ridges and downhill laps

The right approach at the survey stage is to scope these areas as assumed Class A until proven otherwise, with friability called by a competent person (licensed asbestos assessor or occupational hygienist). The right approach at the quote stage is to price Class A scope as a contingency line rather than pretend it doesn’t exist. We covered the survey methodology in Asbestos in Melbourne Homes: How to Identify Before Demolition; the same fundamentals apply at industrial scale, with a deeper inspection list.

Difference 4: Process Plant, Services and Trade-Equipment Decommissioning

A house has four services — electricity, gas, water and telecoms. We walk through them in How We Disconnect Utilities Before Demolition in Melbourne.

A factory has those four, plus a list that doesn’t appear on any residential site:

Refrigeration and HVAC Plant

Almost every commercial and industrial building has refrigerant somewhere — split systems, packaged rooftops, walk-in cool rooms, blast freezers, chillers, condenser units. Refrigerant gases (HFCs, HCFCs, the residual stock of older CFC plant) are regulated under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 (Commonwealth) and must be degassed and recovered by a licensed refrigerant handler before the equipment can be demolished or scrapped.

Industrial-scale refrigeration in cold stores, food-processing plants and beverage facilities can hold tens to hundreds of kilograms of regulated refrigerant — well into five-figure recovery costs if it’s not scoped correctly, and well into six-figure fine territory if it’s vented to atmosphere. This is not a corner you can cut.

Compressed Air, Hydraulic and Steam Systems

Industrial sites typically run compressed-air receivers at 700–1,000 kPa, hydraulic accumulators at higher pressures, and steam plant with stored thermal energy. All of these contain stored energy that has to be safely dissipated before any cutting, dismantling or demolition can begin. Isolation, depressurisation, lock-out/tag-out and documented sign-off — every line.

Electrical Systems Beyond the Domestic Switchboard

A residential disconnection removes 240V single-phase or occasionally 240/415V three-phase via the consumer mains. An industrial disconnection routinely deals with:

Three-phase 415V supply at 200–800A — sometimes higher
Building-mounted or pad-mount transformers owned by the distributor — disconnection and removal involves the distributor’s high-voltage team, on the distributor’s timeline, with documented switching procedures
High-voltage switchgear in older plants (11kV or 22kV)
PCB-containing components in pre-mid-1980s transformers and capacitor banks — Polychlorinated Biphenyls were widely used as transformer oil and capacitor dielectric, are classified as reportable priority waste under Schedule 5, and must be tracked through Waste Tracker
On-site solar arrays (often 100–500 kW on warehouse roofs), batteries, EV chargers
Standby diesel generators with diesel storage and exhaust systems

The high-voltage piece in particular sits on the distributor’s lead time — typically 6–12 weeks in Melbourne — which is one of the longest single tasks on an industrial demolition critical path. Lodging this disconnection late is the single most common cause of avoidable industrial demolition delay.

Fuel and Chemical Storage

Underground and above-ground storage tanks, drum stores, chemical dispensing systems, paint booths, solvent reclaim systems, lubrication systems, fuel-dispensing infrastructure on former service stations and depots. Every one of these is a separate decommissioning and remediation scope before structural demolition, governed by EPA Victoria contaminated-land obligations and (for fuel) by AS 1940 and related standards.

Underground fuel storage tank (UST) removal is its own specialist discipline — confined-space entry, hot-work isolation, vapour management, contaminated soil management around the excavation footprint. On former service stations, depots, and historic industrial sites, UST removal can be 6–10 weeks of standalone work before any structural demolition begins.

Process Plant, Racking and Specialty Equipment

Production lines, food-processing equipment, paint lines, plating tanks, kilns, ovens, conveyors, mezzanines, pallet racking systems (sometimes engineered for 5+ tonne loads per pallet position), overhead gantry cranes, monorails, hoists. Each is its own removal scope, each generates its own waste stream (often heavily recyclable), and each often has residual contamination — process residues, lubricants, plating chemistry — that has to be cleaned to inert status before the equipment leaves site.

The Sequencing Principle

The sequencing rule for industrial decommissioning is straightforward: services first, plant second, asbestos third, structure last. Compress that sequence — start demolishing while plant is still energised, asbestos is still on the roof, or chemicals are still in tanks — and you’ve created an incident waiting to happen.

This is why a properly run Melbourne industrial demolition has a critical path that runs 8–16 weeks before the first structural demolition strike — a fact that catches the most clients out at the quote stage. The plant doesn’t come down in week 1 because it can’t come down in week 1.

Difference 5: Contaminated Land — Why the Soil Underneath Is Often Part of the Job

This is the difference that costs the most when it’s missed.

Industrial and commercial sites in Melbourne carry a contamination history that residential blocks typically don’t. The big categories on Victorian sites:

Hydrocarbon contamination — fuel storage spillage, lubricant leakage, machine-shop oil staining, transport-depot footprints. Common across Brooklyn, Tottenham, Sunshine, West Footscray, Spotswood, Williamstown, Coburg North, Preston East, Thomastown, Dandenong South, Hallam, Heatherton and most former-industrial inner-suburban infill sites.
Heavy metals — historic galvanising, plating, paint manufacturing, foundry operations, battery manufacturing, metal recycling. Lead, chromium, zinc, copper, cadmium all turn up in measurable concentrations on the right type of legacy site.
Chlorinated solvents — historic dry-cleaning facilities, degreasing operations, electronics manufacturing. PCE, TCE and related compounds in soil and groundwater, often migrating off-site through fractured-rock aquifers. The hardest contamination class to clean up and one of the most regulated.
PFAS — increasingly identified on sites with a firefighting-foam training history (former fire stations, defence sites, airports — Tullamarine and Avalon precincts particularly), some industrial fluoropolymer manufacturing, and downstream of firefighting-foam users.
Asbestos-impacted fill — fill brought to the site decades ago, often from other demolition jobs, frequently containing fragmented asbestos cement that wasn’t disclosed at the time. EPA Victoria treats this as reportable priority waste under Schedule 5.
Filled and reclaimed land — particularly relevant to bayside, riverine and former-quarry industrial sites. Fill content is sometimes mixed, sometimes including municipal waste streams from pre-EPA-Act eras.
Acid sulfate soils — coastal and low-lying industrial precincts in Williamstown, Spotswood, Altona and parts of Geelong where natural soil chemistry plus historic disturbance creates acidity risk on excavation.

The Phase 1 / Phase 2 / Auditor Pathway

A properly scoped industrial demolition project starts with a Phase 1 Environmental Site Assessment (ESA) — a desktop review of the site’s history, prior uses, registered tank records, aerial imagery review, and a walk-over inspection by an environmental consultant. Typical cost: $3,500–$8,000 on a standard industrial parcel.

If Phase 1 flags risks (and on most legacy industrial sites it will), a Phase 2 ESA follows with intrusive soil and groundwater sampling. Typical cost: $15,000–$60,000+ depending on site size, number of bores, contaminant suite tested. Phase 2 results dictate:

Whether the soil can be left in place
Whether soil remediation is required before redevelopment
Whether an environmental auditor under the Environment Protection Act 2017 needs to be appointed to verify remediation
What disposal pathway applies to soil that must be removed (Category A, B, C industrial waste, or in serious cases categorised priority waste with its own levy schedule)

The contaminated-soil disposal cost on an industrial demolition can comfortably exceed the structural demolition cost. We’ve quoted jobs where the soil scope was 60–70% of the total contract value.

This isn’t a sales line. It’s the reality of redeveloping Melbourne’s industrial heritage suburbs in 2026. The right demolition contractor flags the contamination scope at the quote stage, prices the structural work transparently, and runs the contamination scope as a separate line item against the environmental consultant’s recommendations — never inside a single “demolition lump sum” where the assumptions are invisible.

The framework on the EPA side is in our EPA Victoria Construction and Demolition Waste Rules 2026 guide. The site-preparation framework that follows the demolition is in Site Preparation After Demolition Melbourne: Before the New Build.

Difference 6: WorkSafe Victoria’s High-Risk-Construction-Work Profile Shifts

The framework is the same as residential — the OHS Act 2004, the OHS Regulations 2017, the WorkSafe Compliance Code: Demolition (Edition 2, 2019). We walk through that framework in WorkSafe Victoria Demolition Requirements: A Plain-English Guide.

But the risk profile under that same framework shifts hard at industrial scale. The high-risk-construction-work catalogue gets ticked harder:

Working at Height Becomes a Dominant Risk

A residential demolition runs almost entirely at ground level — the highest point most workers occupy is a single-storey roof. An industrial roof on a portal-frame warehouse sits at 6–12 metres, occasionally 15+ metres on multi-level facilities. That’s true height, on a substrate that’s often asbestos cement (degrading), profiled steel (sometimes corroded), or both. Working at height on degrading roofing material is one of the highest-fatality combinations in Australian construction.

The control framework: edge-protection scaffold to AS 1576, engineered safety mesh under sheeting, harness-and-anchor systems where mesh isn’t viable, mobile elevating work platforms (MEWPs) where access permits, and no foot traffic on unprotected asbestos cement roofing under any circumstances. The 2019 WorkSafe Compliance Code: Demolition is explicit on this.

Structural Steel Cutting Adds Hot-Works Risk

Where hydraulic shears can’t reach (high-bay roof ties, internal trusswork, secondary bracing), structural steel is oxy-fuel cut or plasma cut. That’s hot-works territory — fire risk, fume hazard, falling slag, dropped-tool risk. Hot-works permits, fire watch, exclusion zones, fume monitoring — all standard, all WorkSafe-anchored.

Plant Movement in Tight Envelopes

Industrial sites often have constrained access — one entry point, narrow site lanes between buildings, neighbouring tenancies still operating in the same complex. Plant movement in that envelope is high-risk by definition. Pedestrian exclusion zones, vehicle movement plans, spotters on every reversing movement, exclusion barriers around the collapse envelope. The WorkSafe expectation is that the No Go Zone framework around overhead and underground services is treated as a non-negotiable.

Pre- and Post-Tensioned Concrete

The Compliance Code: Demolition calls these out separately. Pre-stressed concrete structures store energy in the steel tendons. Cut a tendon under load without controlling the release path and the structure can fail catastrophically — sometimes explosively. Industrial buildings with pre-tensioned beams and post-tensioned slabs (some modern carparks, some mid-rise industrial offices, some bridge-adjacent infrastructure) require structural-engineer-developed demolition methodology before any cutting, with specific load-release sequences and exclusion zones during the tendon-cutting phase.

Confined-Space Entry

Silos, vessels, tank internals, sub-floor service voids, sumps and pits. Confined-space entry is its own regulated regime under the OHS Regulations 2017 — atmospheric testing, ventilation, rescue plan, standby observer, entry permit. Industrial demolition routinely involves multiple confined-space entries. Residential demolition almost never does.

Notifiable Construction Excavation

Industrial slabs sit on substantial footing systems. Pad footings for portal columns commonly run 1.2–2.5 metres deep. Strip footings for masonry walls run 600–900mm. Pile caps, machine bases and special-load footings can go 3+ metres. Excavation to that depth where personnel could enter is notifiable to WorkSafe at least 3 days before commencement under the OHS Regulations 2017 — unless covered by a current Building Act 1993 permit. Industrial jobs run this notification. Residential rarely needs to.

The full framework is in our WorkSafe Victoria Demolition Requirements: A Plain-English Guide. The point for industrial demolition is that the framework is the same — but you’ll tick more of the high-risk-construction-work boxes on a single industrial job than across a year of residential work.

Difference 7: EPA Victoria’s Bite Scales With the Job

The same legislation. The same General Environmental Duty (GED). The same Waste Tracker. The same metropolitan waste levy ($167.90 per tonne from 1 July 2025, with further indexed increases scheduled). But the exposure scales hard with the project size.

The GED at Company Level

A residential demolition that goes wrong — say, asbestos cement is broken on site, fibres are released, the soil is contaminated — is a serious matter. A factory demolition that goes wrong is a serious matter at a different order of magnitude. The same fibres released across 4,000 m² of roof area; the same hydrocarbons released across a 6,000 m² slab; the same noise, dust and stormwater issues across a six-month project rather than a two-week project.

The GED expects you to take reasonably practicable steps to eliminate or reduce risk of harm. On a factory job, “reasonably practicable” is judged against the standard that a competent industrial demolition contractor would meet — a higher standard than for a residential demolition, because the risks are larger, the controls are better understood, and the precedents are clearer. The penalty bands under the Environment Protection Act 2017 — roughly $907,200 for individuals and $1,814,400 for companies per offence — sting at any scale, but on an industrial job the number of potential offences scales with the project too.

Stormwater, Sediment and Dust Across Industrial Sites

A residential demolition’s stormwater control plan is essentially: silt fence around the perimeter, sediment trap at the kerb, swept driveway. An industrial demolition’s plan is a serious document — perimeter sediment control to EPA Environment Protection Authority Victoria Civil Construction, Building and Demolition Guide (publication 1834) standards, on-site treatment swales, designated wash-down areas, settlement ponds on larger jobs, regular stormwater discharge monitoring at perimeter discharge points.

Dust suppression is its own scope. A demolition shift on a 6,000 m² site with concrete pulverising, roof tear-off and slab breakout produces dust at industrial volumes. The control plan needs:

Continuous water-mist suppression during demolition shifts
Wheel-wash facilities at every site exit
Daily street-sweeping of the haul route
Real-time perimeter dust monitoring on dust-sensitive sites (near schools, hospitals, residential areas)
Pollution incident response plan ready for immediate activation

EPA Victoria has been actively prosecuting dust events from demolition sites — particularly on industrial-to-residential conversion projects where the neighbours are sensitive and complaint-active. The duty to notify EPA of pollution incidents is real, and the penalties for failing to notify scale up the offence severity.

Waste Tracker at Volume

Every load of reportable priority waste must be tracked through Waste Tracker — the producer logs it, the transporter (holding A10a or A10b permission) logs it, the receiver logs it. Industrial demolitions generate dozens to hundreds of Waste Tracker entries on a single project. A missed entry, a transporter without the right permission, a destination facility without authorisation for the waste category — any one of these creates duty exposure for the producer.

This is why the documentation pack at the end of an industrial demolition is substantial: every Waste Tracker entry, every weighbridge docket, every disposal receipt, retained for a minimum of 5 years (we recommend 7). Future buyers’ due diligence on the cleared site will look for this paperwork. So will banks, insurers, and any party considering a redevelopment loan.

The Illegal Waste Dumping Taskforce

EPA Victoria’s Illegal Waste Dumping Taskforce has been actively running snap inspections on demolition and waste-transport operators across Melbourne and regional Victoria. The recent enforcement posture — on-the-spot fines, public naming, and court action with six- and seven-figure penalties — is the most active it’s been in over a decade. The economics of cutting corners on industrial demolition waste have flipped: getting caught now costs more than tipping legally, every single time.

Realistic Timelines for Melbourne Industrial Demolition

Every project is scoped against its specific structural typology, services complexity, asbestos quantity and contamination status. With that caveat, the typical durations we see on Melbourne factory and warehouse demolition work look like this:

Project Type	Typical Size	Total Project Duration	Notes
Small standalone industrial unit	200–500 m² GFA	6–10 weeks	Single building, modest asbestos, no contamination
Standard tilt-panel warehouse	1,000–3,000 m² GFA	10–16 weeks	One roof type, on-site crushing, modest plant decom
Mid-century manufacturing facility	2,000–5,000 m² GFA	14–22 weeks	High asbestos volume, moderate plant decom, possible Class A scope
Multi-building industrial complex	5,000–15,000 m² GFA	18–32 weeks	Multiple structural typologies, full plant decom, contamination likely
Heavy-industrial / process plant	Variable	26–52+ weeks	Specialist process decom, Phase 2 ESA likely, environmental auditor commonly involved
Heritage-listed industrial / facade-retention	Variable	26–40+ weeks	Council heritage process, engineered facade retention, slow methodology

These durations are end-to-end — from contract signature through to cleared, validated, documented site. The on-site demolition itself typically takes 30–50% of the total duration; the front-end (approvals, surveys, decommissioning, asbestos removal) and back-end (validation, documentation, environmental sign-off) take the rest.

The realistic critical-path drivers on a typical industrial demolition:

Distributor disconnections (high-voltage particularly) — 6–12 weeks
Hazardous materials survey + asbestos removal plan — 3–6 weeks
Section 29A and asset protection permits — 4–8 weeks (parallelable with planning permit if Heritage Overlay applies, which can run 3–6 months)
Phase 1 ESA (if required) and Phase 2 follow-up — 4–16 weeks
WorkSafe asbestos removal notification — 5 days minimum lead before commencement
On-site asbestos removal — 2–8 weeks depending on volume
Independent asbestos clearance — 1–2 weeks after removal completion
Structural demolition — 3–10 weeks depending on building size and methodology
Slab/footing breakout, on-site crushing and stockpile management — 2–6 weeks
Contaminated soil management (if required) — 2–8+ weeks
Final validation and documentation handover — 2–4 weeks

Compressing this critical path artificially is one of the most common ways industrial demolitions go wrong. A quote that promises an unrealistic timeline is usually pricing the plan, not the work. The full project lifecycle for residential is in From Quote to Cleared Site: Realistic Demolition Timeline Melbourne; industrial projects use the same underlying logic, scaled up and with extra critical-path items.

What a Melbourne Factory or Warehouse Demolition Actually Costs in 2026

Pricing for industrial demolition in Melbourne is normally quoted as a structured line-item scope rather than a single lump sum — the variables are too significant for a square-metre rate alone to give a meaningful picture.

As a 2026 reference range, the major line items typically sit in these bands:

Line Item	Typical Range	Drivers
Structural demolition (single-storey tilt-panel/portal-frame)	$45–$110 per m² GFA	Building height, slab thickness, footing system, access
Multi-storey or high-bay structural demolition	$90–$220+ per m² GFA	High-reach plant, structural complexity, exclusion zone
Heavy-industrial / process-plant demolition	Project-priced	Specialist plant, decom complexity, engineered methodology
Class B (non-friable) asbestos removal	$45–$140 per m² of ACM	Surface type, height, access, quantity, location
Class A (friable) asbestos removal	$200–$700+ per m² of ACM	Enclosure complexity, air monitoring, PPE class
Asbestos-contaminated soil management	$80–$180 per m³	Contamination level, transport distance, disposal facility
Hazardous materials survey (industrial)	$2,500–$15,000+	Site size, building count, sampling density
Phase 1 Environmental Site Assessment	$3,500–$8,000+	Site history, prior-use complexity
Phase 2 ESA (intrusive sampling)	$15,000–$60,000+	Number of bores, contaminant suite, groundwater work
Refrigerant decommissioning	$1,500–$25,000+	Plant count, refrigerant volume, gas type
Underground storage tank removal	$15,000–$80,000+ per tank	Tank size, contamination footprint, disposal pathway
Mobile concrete crusher mobilisation and operation	$15,000–$45,000 setup + per-tonne rate	Site size, expected throughput, duration
Dust suppression unit hire	$1,200–$3,500 per week	Unit class, water supply, shift coverage
EPA waste levy (metropolitan, 2025–26)	$167.90 per tonne	Tonnage to landfill — heavily reduced by on-site recycling
Asbestos waste disposal	Premium over standard levy	Authorised landfill, A10a/b transporter, Waste Tracker
Section 29A demolition consent	~$96.66 (statutory)	5.75 fee units, 2025–26 fee unit value $16.81
Asset protection permit and bond	$323–$465+ permit, bond varies by council	Council, kerb/footpath proximity, security bond schedule

A useful sanity check: a standard 2,000 m² tilt-panel warehouse demolition in a non-heritage outer-Melbourne industrial precinct in 2026, with moderate asbestos quantities and no contamination, typically lands in the $180,000–$420,000 range all-in. A 5,000 m² mid-century manufacturing facility in Brooklyn or Coburg with substantial asbestos and likely contamination typically lands in the $650,000–$1.4 million range. A heavy-industrial process plant in Dandenong South or Laverton North with full plant decom, Phase 2 ESA and environmental auditor involvement can run $2 million plus.

Anything dramatically below those ranges is — as with residential — usually pricing a different, non-compliant job. The most common compliance shortcuts in cheap industrial quotes:

No on-site crushing scoped, with the disposal cost hidden inside an aggressive (often unachievable) recycling assumption
No separate Phase 1/2 ESA scope, with contamination treated as “not our problem”
Class A scope priced as Class B on materials that are clearly friable or borderline
Refrigerant decommissioning omitted or assumed-included without scope
No environmental auditor budget on sites that will need one
Inadequate dust suppression and stormwater control scope, with the implicit assumption that EPA won’t visit

A quote that itemises every line above is genuinely cheaper than a quote that hides them, even if the headline number is higher.

The asbestos-cost framework specifically is in The Cost of Asbestos Removal in Melbourne and Why It Varies. The methodology framework is in Excavator vs Wrecking Ball vs Implosion: Modern Demolition in Melbourne.

Melbourne’s Industrial Demolition Precincts: Where the Work Actually Happens

Industrial demolition isn’t evenly distributed across Melbourne. The work is concentrated in a recognisable set of precincts, each with its own characteristic building stock, contamination profile and redevelopment context.

Inner-West Industrial Heritage (Maribyrnong, Brimbank, Hobsons Bay)

Tottenham, Brooklyn, West Footscray, Yarraville, Sunshine, Spotswood, Williamstown North, Newport — Melbourne’s classic mid-century manufacturing belt. Heavy mix of Type B (steel-frame, Super Six roofing) buildings on parcels being progressively rezoned for medium-density residential and mixed-use. Significant contamination exposure on most parcels — historic foundries, plating works, paint manufacturing, chemical plants. Phase 1 ESA is standard practice; Phase 2 commonly needed; environmental auditor frequently involved. Inner-west councils (Maribyrnong, Brimbank, Hobsons Bay) are active on industrial transitions, with their own neighbourhood character work shaping the redevelopment envelope.

Inner-North Industrial (Merri-bek, Darebin, Yarra)

Coburg North, Brunswick East, Fairfield, Northcote, Preston East, Reservoir (mixed pockets), Collingwood, Cremorne, Richmond (legacy parcels), Abbotsford. A mix of Type A (pre-1950 brick mills) and Type B (steel-frame mid-century). Heritage Overlay coverage is dense across Yarra, parts of Merri-bek and parts of Darebin — many “warehouse demolitions” become facade-retention projects under council heritage process. Contamination exposure varies — long-running food manufacturing, brewing, paint and dye industries leave their marks.

Outer-North Industrial (Hume, Whittlesea, Mitchell)

Campbellfield, Somerton, Thomastown, Epping, Broadmeadows, Tullamarine, Coolaroo. Predominantly Type B and Type C — the mid-century steel-framed plants are progressively being replaced or retrofitted, and the post-1985 tilt-panel stock dominates. Lower contamination exposure on average than the inner-west, but still significant on legacy parcels — automotive (post-Ford), aluminium, manufacturing. Hume’s asset protection permit framework is among the more demanding in metropolitan Melbourne.

Outer-South Industrial (Greater Dandenong, Casey, Cardinia, Kingston)

Dandenong South, Hallam, Lyndhurst, Noble Park, Keysborough, Braeside, Moorabbin (industrial pockets), Heatherton, Springvale. The state’s largest single industrial precinct by GFA. Heavy mix of all four typologies — mid-century manufacturing, modern tilt-panel logistics, heavy-industrial process plant, food-processing facilities. Significant contamination history in Dandenong South particularly — automotive, metals, chemicals, plastics. Phase 2 ESA is the norm, not the exception, on Dandenong South redevelopments. Greater Dandenong council has a well-established industrial-to-residential transition framework.

Outer-West Growth Corridor (Wyndham, Melton, Brimbank-west)

Truganina, Derrimut, Laverton North, Altona North, Sunshine West, Deer Park, Ravenhall, Caroline Springs. The fastest-growing logistics-warehouse precinct in the state. Almost all Type C tilt-panel — and as the stock matures, the first wave of 1990s tilt-panel buildings are now reaching demolition age. Lower contamination exposure than the inner-west on average, though some legacy parcels carry historic landfill and quarry-fill complications. Wyndham’s permit framework is reasonably efficient compared with inner-city councils.

East and South-East (Whitehorse, Knox, Maroondah, Monash)

Bayswater, Kilsyth, Knoxfield, Scoresby, Mulgrave, Notting Hill, Clayton South, Mount Waverley, Burwood East. A scattered industrial fabric of mid-century light manufacturing and modern logistics. Generally lower volume than the major precincts, but with a steady stream of redevelopment work — particularly around the Monash precinct where industrial-to-medical-tech transitions are reshaping older industrial holdings.

Regional Victoria

Geelong (Norlane, North Shore, Corio, Breakwater), Ballarat (Wendouree, Delacombe, industrial west), Bendigo (East Bendigo, Inglewood Road), the Yarra Ranges industrial estates and the Macedon Ranges. Industrial-scale demolition in regional Victoria runs against the same EPA, WorkSafe and Building Act framework as metropolitan work — the regulators don’t change at the city limits. Travel and mobilisation cost more, council process can be slower in smaller LGAs, and contractor availability is thinner.

Industrial Demolition Red Flags: What to Walk Away From

A few specific red flags are worth flagging for industrial clients in particular:

A single lump-sum quote with no line-item breakdown. At residential scale this is bad practice. At industrial scale it’s a serious risk — the asbestos line alone can move six figures, and you can’t reconcile a $400,000 lump sum against any objective benchmark.
No Phase 1 ESA in the scope on a legacy industrial parcel. This is the single most expensive omission. If the contractor doesn’t even mention contamination, walk away.
“No asbestos found” on a pre-1990 industrial building without a written hazardous materials survey. Almost every pre-1990 industrial building in Victoria has asbestos somewhere. A confident “no” without survey evidence is a sales pitch, not a finding.
No named licensed transporter (A10a or A10b permission) for asbestos waste. EPA Victoria publishes the permission register. If your contractor can’t name their transporter, they don’t have one.
No independent licensed assessor named for the asbestos clearance certificate. The removalist cannot clear their own work — the assessor must be independent. If the same business is doing both, the clearance is non-compliant.
No on-site crushing in the scope on a project producing 2,000+ tonnes of concrete and brick. The economics don’t work, and the waste pathway is at best inefficient and at worst non-compliant.
No mention of refrigerant recovery, transformer assessment, or fuel-storage decommissioning on a project that obviously has these systems. Either the contractor hasn’t walked the site, or they’re planning to ignore the obligations.
No public liability insurance certificate showing asbestos coverage and adequate sums insured ($20 million is the working minimum for industrial demolition; $50 million is increasingly standard on larger projects). Licensed Asbestos Removal Victoria: How to Verify Your Contractor walks through the insurance verification.

Frequently Asked Questions

How long does it take to demolish a warehouse in Melbourne?

For a standard single-storey tilt-panel warehouse of 1,000–3,000 m² with moderate asbestos and no significant contamination, expect a total project duration of 10–16 weeks from contract signature to cleared, validated site. On-site demolition itself is typically 3–6 weeks of that window — the front-end (approvals, surveys, decommissioning, asbestos removal) and back-end (validation, documentation) take the rest. Larger multi-building complexes, mid-century manufacturing facilities, and heavy-industrial process plants run substantially longer — 18 weeks to over a year for the most complex sites.

How much does it cost to demolish a factory or warehouse in Victoria?

There’s no single per-square-metre rate because the variables are too significant. As a working reference for 2026: a standard 2,000 m² tilt-panel warehouse in outer Melbourne with moderate asbestos and no contamination typically runs $180,000–$420,000 all-in. A 5,000 m² mid-century manufacturing facility with substantial asbestos and likely contamination typically runs $650,000–$1.4 million. A heavy-industrial process plant with full plant decommissioning and Phase 2 ESA can run $2 million plus. Always insist on a line-item breakdown — structural demolition, asbestos, services decommissioning, contamination management, waste disposal, council fees — rather than a single lump sum.

Do I need a planning permit to demolish an industrial building in Victoria?

Only if the property is affected by a planning control that triggers one — most commonly a Heritage Overlay, but also sometimes a Neighbourhood Character Overlay, a Significant Landscape Overlay, an Environmental Significance Overlay, or a restrictive covenant on title. Industrial buildings in Yarra, Merri-bek, Maribyrnong, Hobsons Bay, and parts of Stonnington, Port Phillip and the City of Melbourne commonly sit inside Heritage Overlays and require planning permits before Section 29A demolition consent can be issued. The framework is in our Council Demolition Permits in Melbourne: A Suburb-by-Suburb Overview.

What’s different about asbestos in factories compared with houses?

The quantity is on a different order of magnitude — a mid-century warehouse can carry 5,000–10,000 m² of non-friable asbestos cement (mostly Super Six roofing), compared with 80–200 m² in a typical residential property. The friable hot spots are also more concentrated — pipe lagging, sprayed limpet insulation, boiler millboard, gaskets and switchboard backing are far more common in industrial buildings than in homes. And the height at which the work happens — industrial roofs at 6–12 metres — adds working-at-height risk that residential work rarely faces. The licence framework is the same (Class B for non-friable, Class A for friable), but the scale, sequencing and edge-protection requirements are different. We covered the licence framework in The Difference Between Friable and Non-Friable Asbestos in Demolition.

Do I need an environmental site assessment before demolishing a factory?

For most legacy industrial parcels in Melbourne, the answer is effectively yes — particularly if the site is going to be redeveloped for residential, mixed-use or sensitive uses. A Phase 1 Environmental Site Assessment is the standard starting point on any property with a contamination-prone history (manufacturing, foundry, plating, paint, chemicals, fuel storage, food processing). If Phase 1 flags risks, a Phase 2 ESA with intrusive sampling follows. Phase 2 results dictate whether soil remediation is required, what the disposal pathway is, and whether an environmental auditor under the Environment Protection Act 2017 needs to be appointed. This is rarely the demolition contractor’s primary scope — it’s an environmental consultant’s job — but a good demolition contractor will flag the requirement at quote stage.

Can the asbestos roof on an industrial building be removed while the building is still operating?

In principle yes, but with significant additional controls — exclusion zones around the work area, careful sequencing to avoid pedestrian traffic underneath, full edge protection, and either after-hours scheduling or staged closures of the operational floor. In practice, most industrial asbestos roof removals happen as the first phase of a full demolition, with the building decommissioned and the site cleared of personnel before work starts. Removing an asbestos roof on a still-operating warehouse is a legitimate scope where the building has a longer working life — we run those projects too — but it’s a different methodology and a different price than the demolition-phase removal.

Do I need to remove the concrete slab and footings, or can they stay?

This depends on the redevelopment intent. If the site is going back to industrial use with a new building roughly on the same footprint, structural slab and footing retention may be viable — subject to the new building’s structural engineer signing off on the geotech and existing structure. If the site is going to residential, sensitive use, or a substantially different industrial use, full slab and footing removal is almost always required. The slab is typically 150–300mm of reinforced concrete with strip and pad footings extending 0.6–2.5+ metres below ground. On-site crushing processes this into recycled aggregate; full removal is a substantial scope in itself. Our Site Preparation After Demolition Melbourne: Before the New Build guide walks through the post-demolition sequence.

What permits and notifications do I actually need for an industrial demolition?

Most industrial demolitions in Victoria require a combination of: a planning permit (where Heritage Overlay or similar applies), a Section 29A demolition consent under the Building Act 1993, a building permit for demolition issued by a Registered Building Surveyor, an asset protection permit from the local council, WorkSafe Victoria asbestos removal notification (5+ days before commencement for licensed asbestos work), WorkSafe construction excavation notification (3+ days before excavation where personnel could enter), distributor service disconnection applications (electricity including any HV, gas, water, telecoms — lodged in parallel, not sequentially), and EPA Waste Tracker registrations for every reportable-priority-waste stream. Our What Is a Demolition Consent and How Do You Get One in Victoria guide walks through the Section 29A piece.

Can I demolish my own factory if I own it outright?

You own the asset, but the regulatory framework applies regardless of ownership. WorkSafe Victoria still expects a competent person to identify hazards and prepare SWMS. EPA Victoria still expects waste to be classified, tracked and lawfully disposed of. The Building Act 1993 still requires Section 29A consent and a building permit for demolition. WorkSafe asbestos removalist licensing still applies to any asbestos work over the 10 m² / 1 hour exemption (essentially never on industrial work). In practice, industrial demolition is almost always carried out under a registered demolition contractor’s licence, with the building owner as the client — the in-house “do it yourself” route doesn’t realistically work at industrial scale.

What happens to the asbestos waste from a factory demolition?

It’s pre-classified as reportable priority waste under Schedule 5 of the Environment Protection Regulations 2021, regardless of quantity. Every load must be: wrapped in 200 µm polythene (sheets) or double-bagged (smaller pieces) and clearly labelled; transported by a permission holder (A10a for high-risk RPW or A10b for other RPW); tracked through EPA Waste Tracker by the producer, transporter and receiver; and disposed at an EPA-authorised landfill licensed to receive asbestos waste. The producer (the demolition contractor and ultimately the property owner) remains legally responsible for the waste until it reaches the authorised place. Disposal cost runs at a premium over the standard $167.90/tonne metropolitan levy because asbestos categories attract their own fees.

Is on-site concrete crushing worth it on an industrial demolition?

For most industrial demolitions producing 2,000+ tonnes of concrete and brick, yes — comfortably. The metropolitan waste levy alone on raw mixed-waste disposal of 4,000 tonnes is over $670,000 at 2025–26 rates, before tipping fees. On-site crushing converts clean concrete and brick (typically 60–80% of the waste stream by weight) into recycled aggregate that avoids the levy entirely, often holds modest resale value, and can be reused as fill or sub-base for the new build. The crusher mobilisation cost is $15,000–$45,000 typically, with a per-tonne processing rate, but the net economics on any large industrial job are decisively in favour of on-site processing. The exception is small industrial demolitions (under ~1,500 tonnes) where mobilisation cost doesn’t pay back.

What’s the difference between a Class B and Class A asbestos licence for industrial work?

The same as for residential work — Class B covers non-friable (bonded) asbestos like Super Six roofing, cement-sheet wall cladding, vinyl floor tiles and most fibro panels. Class A covers friable asbestos like pipe lagging, sprayed limpet insulation, boiler millboard, gaskets, and any ACM whose condition has degraded (fire-damaged, water-damaged, mechanically broken). Industrial buildings are more likely than residential properties to need both licence classes on the same project, because the friable hot spots (lagging, insulation, gaskets) are more common in factories than in homes. We hold a Class B licence in-house and partner with Class A specialists where required.

What’s the largest single demolition risk on an industrial site?

Working at height on degrading asbestos-cement roofing is the highest-fatality combination on Australian construction sites by a substantial margin. Industrial roofs sit at 6–12 metres, the substrate is brittle and weather-degraded, and the asbestos exposure is significant once the sheeting is disturbed. Properly controlled work involves edge-protection scaffolding to AS 1576, engineered safety mesh under the sheeting, harness systems where mesh isn’t viable, and an absolute prohibition on unprotected foot traffic on asbestos cement roofing. The WorkSafe Victoria Compliance Code: Demolition (Edition 2, 2019) is explicit on this — there is no “shortcut” version of this control framework that’s compliant.
