Mining and Earthmoving Contractor Insurance — What You Need on Site

Contractors working on mine sites, in gas fields or on civil earthmoving projects face a distinct combination of insurance requirements. Site entry conditions, contractual insurance schedules and the high value of plant and equipment all need to be considered when structuring cover. Getting it wrong can mean being turned away at the gate — or facing an uninsured loss in a high-consequence environment.

Public and products liability

Public liability is non-negotiable for any contractor working on a mine site or major civil project. Most site entry requirements specify a minimum limit — commonly $10 million, $20 million or higher for principal contractors or those operating heavy plant near critical infrastructure.

What mine sites commonly require

• A minimum limit of indemnity (check the contract’s insurance schedule — don’t assume)
• The principal and sometimes their financiers or government authorities noted as an interested party
• Cross-liability provisions — so that claims between contractors on the same project are covered as if each held a separate policy
• Waiver of subrogation in favour of the principal
• A certificate of currency matching the requirements in the contract exactly

The specific requirements vary by site and contract. Read the insurance schedule carefully — a general liability policy that meets most requirements but misses a specific endorsement can create a compliance issue that delays site access.

Plant and equipment insurance

For earthmoving and mining contractors, mobile plant is typically the most significant asset on the balance sheet. Plant cover needs to reflect the way equipment is owned, financed and used.

Owned plant

Plant and equipment policies cover owned machinery for physical loss or damage. Key considerations include:

• Agreed value vs market value — agreed value policies pay the insured value without depreciation deducted. For high-value or specialised plant, agreed value is generally preferable.
• Schedule accuracy — every machine should be correctly identified (make, model, serial number, value). Unscheduled plant is often not covered or may only receive cover up to a limit.
• Finance and lease interests — if equipment is financed, the financier’s interest should be noted on the policy.
• Road risk — plant travelling on public roads needs road risk cover, which may not be automatic under a plant policy. Check whether road transit between sites is covered.

Hired-in plant

If you hire in equipment, the hire agreement usually makes you responsible for loss or damage during the hire period. Your policy should clearly cover hired-in plant or you’ll need to assess whether the hire company’s own policy provides adequate cover for your exposure.

Dry hire vs wet hire

Dry hire (plant without an operator) and wet hire (plant with an operator supplied by the owner) are treated differently by insurers. If you’re providing plant to others on a dry hire basis, you retain ownership risk during that period — check how your policy treats this.

Workers compensation

Workers compensation for mining and earthmoving operations is compulsory and state-specific. The classification of workers — direct employees, labour hire, subcontractors — affects premium calculation and must be accurately declared. Mining operations have specific classifications in most state schemes.

For operations that cross state borders, understanding the applicable jurisdiction for each worker is important — workers compensation legislation is state-based, and the rules for determining which state’s scheme applies can be complex for mobile workforces.

Professional indemnity

Not all mining and earthmoving contractors need professional indemnity — but it becomes relevant when you’re providing:

• Geotechnical assessments or advice
• Survey or design input as part of your scope
• Blast design or explosive management
• Environmental or rehabilitation services
• Project management or supervision roles with design responsibility

If your contract scope includes any advisory or design element, check whether your contract requires PI cover and whether your current policy covers that scope of services.

On-hire liability

If you supply labour to another contractor or principal on a labour-hire basis, on-hire liability cover addresses claims arising from the actions of your workers while they’re working under another party’s direction. This is a niche but important cover for contractors who supply labour to mine sites under secondary agreements.

Preparing your certificate of currency

Most site entry processes require a current certificate of currency that matches the contract’s requirements exactly — correct policy number, correct noted parties, correct limit. Certificates generated automatically by insurers may not include all the required endorsements.

Allow time to obtain a properly endorsed certificate before your planned start date — last-minute certificate requests can delay site access if the insurer needs to make specific endorsements to the policy.
