Closing, relocating or modernising a factory leaves behind machines, structures, utilities and stores. Handled well, dismantling can recover significant value and leave a clean, safe site. Handled badly, it can cause accidents, legal problems and a fraction of the value you should have received. This guide explains how to plan plant dismantling and sell machinery and structural scrap well.
Step 1: Take inventory
Start with a complete list:
- Production machinery: Lathes, CNC machines, presses, furnaces, extruders, mills.
- Utilities: Boilers, compressors, DG sets, transformers, HT/LT panels, cooling towers, chillers.
- Material handling: Cranes, hoists, conveyors, forklifts.
- Structures: Sheds, mezzanines, tanks, silos, pipe racks, chimneys.
- Electricals: Cables, bus ducts, lighting, motors.
- Stores and spares: Bearings, gears, tools, consumables.
- IT and controls: PLCs, computers, servers.
Record make, model, year, condition and approximate weight where possible.
Step 2: Separate resale from scrap
Not everything should be scrapped. Working machines, utilities and spares may sell as used equipment for far more than their metal value. Consider:
- Age and condition: Well-maintained equipment from recognised makers often has resale demand.
- Market demand: Some machine types sell quickly; others are obsolete.
- Time: Selling machines individually takes longer than a single scrap deal.
A practical approach is to identify high-value resale items first, offer them for a fixed period, and scrap the rest.
Step 3: Estimate scrap value
For scrap items, value comes from metal content:
- Ferrous structures and machine bodies (MS and cast iron).
- Copper and aluminium in motors, transformers, cables and windings.
- Stainless steel in process equipment and tanks.
- Brass and gunmetal in valves and bushes.
Estimate weights from drawings, manufacturer data or experience, and apply current grade-wise rates. This gives you a benchmark to evaluate offers.
Step 4: Understand dismantling costs
Dismantling involves:
- Gas cutting and mechanical cutting.
- Cranes and lifting equipment.
- Skilled labour and supervision.
- Safety equipment and scaffolding.
- Transport.
- Debris removal and site cleaning.
- Disposal of non-recyclable waste.
In most industrial dismantling, the scrap value exceeds dismantling cost, so the buyer pays the owner. For complex or hazardous sites, the net may be smaller.
Step 5: Invite combined offers
Ask qualified contractors to quote dismantling and scrap purchase together. Request:
- Scope of work and exclusions.
- Grade-wise rates for scrap, or a lump sum.
- Timeline and work sequence.
- Safety plan and insurance.
- Equipment and manpower deployed.
- Payment schedule.
- Site restoration commitments.
Compare offers on net value, safety credibility and timeline, not only headline price.
Step 6: Plan for safety
Dismantling is high-risk work. Insist on:
- A written method statement and risk assessment.
- Hot work permits for gas cutting, with fire watch and extinguishers.
- Isolation and lock-out of electrical, gas and steam lines.
- Work-at-height controls: harnesses, scaffolding, edge protection.
- Lifting plans for heavy items, with certified cranes and rigging.
- PPE for all workers.
- Insurance covering workers and third parties.
- A competent supervisor on site at all times.
The site owner retains significant responsibility, so do not compromise here.
Step 7: Handle hazardous materials
Old plants often contain:
- Transformer and hydraulic oil: Must go to authorised used-oil re-refiners.
- Asbestos: In older roofing and insulation; requires specialised removal.
- Chemicals and residues: In tanks and pipelines; clean and dispose properly.
- Lead-acid batteries: To authorised recyclers under battery waste rules.
- E-waste: To authorised recyclers under e-waste rules.
- Refrigerants: Recover properly from chillers and AC units.
Ask the contractor how they will handle each, and get disposal certificates.
Step 8: Contract and payment structure
For larger projects, structure payments to protect the owner:
- Advance or security deposit from the buyer before work starts.
- Lot-wise payment against weighbridge weights as material leaves.
- Balance and deposit release after site handover and completion.
Include clauses on schedule, penalties for delay, safety breaches, theft, and dispute resolution.
Step 9: Weighment and gate control
- Every outgoing truck is weighed at a certified weighbridge.
- Gate passes and challans match truck numbers and weights.
- The owner's representative supervises loading.
- Weekly reconciliation of weights against estimates.
Step 10: Documentation and accounting
- Board or management approval for asset disposal.
- Fixed asset register write-off.
- GST invoices on sale, with correct HSN codes and treatment of metal scrap rules.
- E-way bills for movement.
- Hazardous waste disposal records.
- Final site handover certificate.
Capital goods sold as scrap may also have GST implications related to input tax credit previously claimed. Consult your accountant.
Typical timelines
- Small workshop: a few days.
- Medium factory shed with machinery: two to six weeks.
- Large plant: several months, often in phases.
Common mistakes
- Scrapping machines that could have been sold as working equipment.
- Selecting a contractor on price alone.
- Allowing cutting without hot work permits.
- Ignoring hazardous materials until they become a problem.
- Releasing full possession before receiving payments.
- Poor gate control leading to theft.
A worked example: valuing a closed foundry shed
A small foundry in Purvanchal closes one shed containing an old induction furnace, moulding machines, an EOT crane, a 500 kVA transformer, cables, and a steel structure shed of about 1,500 square metres.
The owner breaks the project into parts:
| Item | Approach |
|---|---|
| EOT crane | Check resale demand; often sells as working equipment |
| Transformer | Identify winding material; quote whole-unit and component-wise |
| Moulding machines | Mostly cast iron; resale if serviceable, else CI scrap |
| Induction furnace | Copper coil and power electronics have value; refractory is waste |
| Cables | Sell on recovery basis |
| Steel shed structure | Weigh estimate from drawings; MS scrap after dismantling |
| Refractory, debris | Disposal cost to be included |
By offering the crane and some machines for resale first, then inviting combined dismantling-plus-scrap offers for the rest, the owner recovers more value than a single "as-is" sale and gets a clear net figure.
Dismantling checklist for site owners
- Complete inventory with photos.
- Resale assessment for working equipment.
- Hazardous materials identified and plan agreed.
- Contractor shortlisted on safety record, equipment and references.
- Written scope, timeline, payment structure and security deposit.
- Permits, isolation and insurance confirmed before work starts.
- Daily supervision, gate control and weighbridge records.
- Site handover inspection and final settlement.
Typical timeline for a medium factory dismantling
| Week | Activity |
|---|---|
| 1 | Inventory, photos, drawings, resale list prepared |
| 2 | Resale offers invited; hazardous materials identified |
| 3 | Combined dismantling-plus-scrap quotes; contractor shortlisted |
| 4 | Contract signed, deposit received, permits and isolations done |
| 5–8 | Machinery removal, cutting, loading and weighbridge weighment |
| 9 | Structure dismantling, debris removal, site cleaning |
| 10 | Final reconciliation, payments, handover certificate |
Larger plants run in phases over several months, but the sequence is the same: value first, safety plan second, physical work third, paperwork throughout.
Questions to ask a dismantling contractor
- How many similar projects have you completed, and can we speak to those clients?
- What lifting equipment and gas-cutting teams will be deployed, and are they yours?
- Who is your site safety supervisor, and what insurance do you carry?
- How will you handle oil, asbestos, chemicals, batteries and refrigerants?
- How will weights be recorded, and how often will payments be made?
Value often missed during dismantling
Spare parts stores, unused cable drums, copper bus bars inside panels, brass valves on utility lines and stainless tanks in effluent plants are frequently overlooked when a plant is valued only by its structure. Walk every building, utility room and store before finalising the inventory.
