Insurance is the most predictable cause of tender exclusion in Australian civil construction, and the least interesting to fix. A certificate that expired three weeks before the closing date, a public liability limit of $10 million against a stated requirement of $20 million, a certificate of currency for the wrong entity in a group, a policy schedule submitted where a certificate was asked for — none of these are judgement calls by an evaluation panel. They are compliance checks, they are made before any technical assessment begins, and failing one is generally fatal regardless of how good the rest of the submission is.
That is the administrative half of the problem, and most contractors eventually solve it. The commercial half is harder and much less discussed: satisfying the tender’s stated limit is not the same as being insured for the work. A $20 million public liability policy that excludes excavation below two metres, or damage to underground services, or vibration and removal of support, will pass the compliance check on a drainage tender and then fail to answer the claim that the drainage work actually generates.
This guide covers both halves. It assumes you are bidding government and council civil work in the $50,000 to $2 million band. For where insurance sits inside the broader compliance and prequalification picture, see our prequalification reference guide; for how to present it inside a document, see the capability statement worked example.
One necessary caveat before anything else. Nothing here is insurance advice, and insurance is one of the few areas of tendering where a competent broker genuinely cannot be substituted with reading. Policy wordings differ materially between insurers, the same cover is named differently by different underwriters, and the questions raised in this guide are questions to put to a broker who understands civil exposures — not answers.
Why insurance is a gate, not a scored criterion
Understanding where insurance sits in the evaluation sequence explains why it behaves so differently from the rest of a submission.
Most civil tenders separate mandatory conformance requirements from weighted evaluation criteria. Insurance almost always sits in the first group. It is checked as a yes-or-no question — does the tenderer hold the specified covers at the specified limits, evidenced as specified — before the panel reaches methodology, program, capability or price. A non-conforming tender can be excluded from further consideration at that point without any scoring occurring.
Three consequences follow, and they are all counter-intuitive.
- There are no marks for exceeding the limit. Carrying $50 million public liability where $20 million was required buys you nothing in the evaluation. It is a cost with no scoring return. This is the most common form of over-insurance among growing contractors, usually a legacy of one large project’s requirements never being revisited.
- There is no partial credit for nearly complying. A $19 million limit against a $20 million requirement is a fail, not a small deduction.
- Insurance is rarely where the risk actually is. Because it is a conformance item, contractors treat it as an administrative box. The commercial exposure — whether the policy answers a civil claim — is invisible to the evaluation and therefore invisible to the bid team.
There is a second gate that is easy to miss. Where a tender requires cover you do not currently hold — a higher limit, or a cover you have never needed — you will generally be permitted to tender on the basis of an undertaking to effect that cover on award. What you must not do is assert current cover you do not have. A broker’s letter confirming that cover at the required limit is available and will be bound on award is the correct instrument, and it should be obtained before submission, not after.
The six covers a civil tender asks for
Requirements vary by agency, contract value and scope, but the set converges. For civil works in the $50,000 to $2 million band the following is the working expectation, and $20 million public liability has become the de facto standard across state road authority and significant council work, with $10 million still accepted for smaller council and subcontract packages.[1]
| Cover | Typical requirement | What it actually responds to |
|---|---|---|
| Public and products liability | $20 million per occurrence for road authority and significant council work; $10 million sometimes accepted for smaller council and subcontract work[1] | Your legal liability for third-party injury or property damage arising from the works |
| Contract works / construction all risks | Full contract value, commonly plus a margin for variations, professional fees and debris removal[2] | Physical loss or damage to the works themselves and materials on site — first-party, not liability |
| Workers compensation | Compulsory cover under the scheme of each state or territory in which you employ workers | Statutory entitlements of injured workers |
| Motor vehicle and mobile plant | Comprehensive cover for fleet and registered plant; CTP as required by state law | Own damage and third-party liability arising from vehicles and mobile plant |
| Professional indemnity | $5 million to $10 million where any design, engineering or advisory element is in scope; Victoria’s Construction Supplier Register requires $5 million for works categories[3] | Liability arising from professional advice or design, including negligent omissions |
| Environmental impairment liability | Project-specific; increasingly requested on works near watercourses, contaminated land or sensitive receptors | Gradual pollution and clean-up costs that general liability typically excludes |
Note the boundary between the first two rows, because it is the distinction contractors most often collapse. Contract works is first-party material damage cover on the works under construction. Public liability is third-party cover for injury and damage you cause. They are different policies answering different events, and holding one does not mitigate the absence of the other.[4] A storm that destroys a partially completed retaining wall is a contract works claim. The same storm washing sediment into a neighbouring property is a liability claim.
One point of sequencing worth knowing. Insurance minimums are rarely specified at the prequalification stage — they appear in the tender documents and the contract.[1] Contractors who assume prequalification has settled their insurance position are frequently surprised at first tender.
Public liability: the limit is the easy part
Public liability is the cover that gets all the attention in tender documents and almost none of the attention it deserves in policy review. The number is easy to check. What the policy actually does is not.
Four structural questions determine whether your policy is fit for civil work, and none of them appear in a tender’s insurance schedule.
- Is the limit per occurrence or in the aggregate? A $20 million limit in the annual aggregate is a materially weaker instrument than $20 million per occurrence, particularly for a contractor running several jobs concurrently. Tenders usually specify per occurrence; policies do not always deliver it.
- Is products liability included, and on what basis? Relevant where you supply materials — quarry products, precast items, asphalt — as distinct from installing them.
- What is the excess, and who bears it? Civil policies commonly carry differentiated excesses, with a much higher excess for specific exposures. Damage to underground services is the classic example, and negotiating that excess down is one of the more valuable things a broker does for an earthmoving contractor.[5]
- Is there a worker-to-worker excess? Many policies impose a separate excess where the claim is for injury to a labour hire worker or another contractor on site — commonly in the $10,000 to $25,000 range and sometimes as high as $50,000.[5] On a civil site running subcontract crews, this is one of the most likely claims you will ever make, and it is the one your policy is quietly least generous about.
The civil exclusions that make the limit meaningless
This is the section of this guide that matters most, and it is the one that has no equivalent in any tender document. Standard public liability wordings were not designed around excavation, and the exclusions that follow apply directly to the core activity of a civil contractor. Every one of them is common, and several are routinely present in policies held by contractors who believe themselves fully covered.
| Exclusion or condition | What it removes | What to ask your broker |
|---|---|---|
| Underground services | Damage to buried pipes, cables, conduits and services. Commonly excluded outright, or covered subject to conditions such as obtaining service location records before excavating[6] | Is this covered, at what sublimit, at what excess, and what pre-excavation evidence does the insurer require? |
| Vibration, removal or weakening of support | Subsidence and cracking to adjoining structures from excavation, demolition or driven piling. Excluded outright in some policies, sublimited or conditioned in others[7] | Is the extension purchased? What is the sublimit against the value of adjacent assets? |
| Depth and height limitations | Work beyond a stated depth. Exclusions at one or two metres are common in general business liability policies; some civil policies cap at ten metres without endorsement[8] | What is the depth limit on my policy, and does it cover the deepest trench I have priced? |
| Care, custody or control | Damage to property in your care, custody or control — which on a civil site can include the principal’s existing assets[9] | Is the extension available, and does it respond to principal-owned infrastructure I am working on? |
| The part being worked immediately upon | Damage to the very element you are working on. Broadly interpreted, and a live issue on rehabilitation and renewal scopes[9] | On a renewal contract, what is “the part being worked upon” and how is my exposure structured? |
| Hot works | Cover for welding, cutting and grinding is typically subject to conditions including fire watchers and permit systems[7] | What exactly must my site procedures do for cover to hold? |
| Asbestos | Asbestos-related liability is commonly excluded. Directly relevant to asbestos cement main renewals and older road and building substrates[8] | If AC pipe or ACM is in scope, what cover exists and what is required to trigger it? |
Read the underground services and depth entries together, because in combination they describe an excavation contractor with no meaningful cover for excavation. Striking a buried service is among the highest-frequency claims in civil work and can readily exceed tens of thousands of dollars.[8] A policy that excludes it, or covers it subject to conditions your site procedures do not actually satisfy, is not fit for the work regardless of what the certificate says.
The conditional nature of the underground services cover deserves particular emphasis. Where cover is subject to obtaining service location records before excavating, that is not a suggestion — it is a condition of the policy responding. Which means your dial-before-you-dig process, your service location records, and your evidence of having done both are simultaneously a work health and safety control, a methodology inclusion and an insurance requirement. If your WHS management plan and SWMS describe a service location process you do not follow in practice, you have created a documented gap between your stated controls and your actual ones, and an insurer will find it.
There is an instructive contrast in how differently regulators treat some of these exclusions. Victoria’s ministerial insurance requirements for building practitioners expressly prohibit policy terms that exclude cover by reason of claims for personal injury or property damage arising from the erection, demolition, alteration of or addition to buildings or temporary structures, or any vibration, or any removal or weakening of support caused thereby.[10] That is a regulator identifying the vibration and support exclusion as unacceptable in a mandated cover. It applies to a different category of practitioner and does not carry across to civil contracting, but it tells you how significant the exclusion is understood to be.
Contract works: sum insured, the margin, and when cover stops
Contract works insurance, also sold as contractors all risks, covers physical loss or damage to the works during construction — storm, fire, flood, accidental damage, theft of materials — together with materials and equipment awaiting installation and, usually, temporary works such as formwork and falsework.[7]
Every standard-form major works contract in Australian use, from AS 4000 and AS 2124 through AS 4300 and the building industry forms, contains a clause obliging a party to arrange and maintain insurance on the works, and specifying which parties are to be covered.[4] Failure to comply is generally a ground for suspension of payment or termination.[2] Note that AS 4000 was updated in 2025 — Standards Australia released AS 4000:2025 on 30 June 2025, retaining the core structure while modernising provisions to reflect current legislation and practice.[11] If you are working from a familiarity with the 1997 edition, check which edition the contract you are pricing actually incorporates. Our comparison of AS 4000 and AS 2124 covers the differences that matter commercially.
Four practical points on the cover itself.
- Insure the full contract value plus a margin. The conventional allowance is at least ten per cent for variations and professional fees, plus a sum for debris removal.[2] This is not conservatism for its own sake — underinsurance can trigger an average clause, which reduces the claim payment in proportion to the shortfall.[2] A contractor who insures a $900,000 job for $900,000 and then executes $150,000 of variations has quietly created an underinsurance position across the whole policy.
- Know when the cover ends. Most contract works policies cease at practical completion, handover, or when the principal takes possession or occupies the works, whichever occurs first.[2] That leaves the defects liability period covered by a different mechanism, if at all. Where you are returning to site to rectify defects, confirm what responds.
- Check whether subcontractors and principal-supplied materials are covered. Both differ between insurers, and neither is safe to assume.[2] Principal-supplied materials are a live issue on council work, where the council may supply pipe, precast units or aggregate.
- Note the interested parties correctly. Construction contracts usually require the principal, and sometimes subcontractors and financiers, to be noted on the contract works policy so that they hold an insurable interest.[4] A policy that does not name them does not comply with the contract, whatever its limit.
A related terminology warning. The same product is labelled contract works by some insurers and construction all risks or CAR by others, and the structures are not identical.[2] Read the schedule rather than the product name.
Existing structures and the part being worked upon
This is a genuinely difficult area and it is where a great deal of SME civil work sits — culvert rehabilitation, pavement renewal, water main replacement, kerb replacement, bridge repair. The common feature is that you are working on or immediately adjacent to an existing asset you do not own.
The liability path is unattractive. Public liability responds to your legal liability, which means a claim requires establishing fault. It generally excludes the part being worked immediately upon, an exclusion open to broad interpretation. It may exclude property in your care, custody or control. And it commonly excludes or sublimits vibration and removal of support — the very mechanisms by which renewal work damages adjacent structures.[9]
There is an alternative structure that is under-used by SMEs. Where an existing structure is insured under a material damage policy — either for its full value or on a first-loss basis for a nominated amount — the position changes substantially. Material damage cover removes the need for the insured to prove legal liability, mitigates the liability exclusion for the part being worked immediately upon, and in practical effect renders the vibration, weakening and removal of support exclusion redundant for that structure. It also mitigates the problem of the owner’s own damage and can satisfy contractual indemnity requirements that go beyond what the law would impose.[9]
Two qualifications. First, material damage policies commonly exclude loss resulting from fault, error or defect in workmanship, design or material — so the structure is protected against the consequences of your work, not against your work being wrong.[9] Second, where any existing structure passes into your care, custody or control, appropriate sum insured allowances must be made and the policy’s care, custody and control terms must be accounted for.[9]
The practical instruction: on any renewal or rehabilitation contract, identify at tender stage which existing assets are exposed, what they are worth, and who insures them. If the contract makes you responsible for damage to them, the question of whether a material damage arrangement is required belongs in your bid, and in your price.
Plant, motor vehicle and hired-in equipment
Plant cover is the least contested of the required covers and the one most likely to contain an unnoticed gap, because plant arrives on a civil site through several different commercial routes and each is insured differently.
- Owned registered plant and vehicles. Comprehensive motor cover plus compulsory third party as required in the state of registration. Straightforward.
- Owned unregistered mobile plant. Excavators, rollers, compactors and similar. Covered under mobile plant or contractors plant and equipment sections, which respond to own damage. Third-party liability arising from their operation may sit under the plant policy or the public liability policy depending on the wording — and the boundary is where disputes occur.
- Dry-hired plant. The hire agreement almost always makes you responsible for damage to the machine and for its continuing hire charges while it is out of service. Hired-in plant cover, including a hiring charges extension, is the specific answer. Contractors regularly discover its absence after an incident.
- Wet-hired plant and labour. The operator’s employer carries the workers compensation exposure and usually the plant cover, but your liability for the operator’s actions on your site is a separate question governed by the hire terms.
- Plant on hire to others. If you hire your plant out between jobs, confirm that cover follows it.
Tender documents rarely specify plant insurance limits with any precision, which is why this section is easy to skip. The exposure is nonetheless real and immediate: a $400,000 excavator damaged on a $600,000 contract is an event that ends a small contractor, and it will not be answered by the public liability policy the tender asked about.
Workers compensation and the cross-border trap
Workers compensation is compulsory wherever you employ workers, and it is administered separately in each state and territory — icare in New South Wales, WorkSafe in Victoria, WorkCover in Queensland, and the equivalent scheme in each other jurisdiction. It is the one cover in this guide that is not a commercial negotiation: the scheme sets the terms and the premium is calculated on your wages and industry classification.
Three issues arise repeatedly for civil contractors and all three are avoidable.
- Cross-border work. A contractor headquartered in one state that sends crews to work in another needs to establish which scheme covers those workers. The tests turn on the worker’s state of usual connection rather than on the location of a single job, but they are not intuitive and the consequences of getting it wrong are statutory rather than contractual. Tenders in a neighbouring state should trigger this question before submission, not after award.
- Working directors and contractors. Whether working directors, sole traders and independent contractors are covered — and whether they must be — varies by scheme. A tender’s insurance schedule may ask for cover for “all persons engaged in the works”, which is a broader statement than a standard policy necessarily delivers.
- Currency evidence and the ordering of documents. Workers compensation certificates are generally issued for a policy year and are a routine element of the compliance cabinet. They are also among the most frequently expired documents at the moment of tender submission.
Where a tender requires evidence that your subcontractors hold workers compensation cover — increasingly common — that obligation is yours to discharge and it requires a collection and verification process rather than a request at the last minute. That collection also protects you against liability for a subcontractor’s unpaid premiums, as our guide to workers compensation and injury management explains.
Professional indemnity: when construct-only is not
Most SME civil work is construct-only, and construct-only work does not on its face require professional indemnity cover. In practice the boundary is far less clean than contractors assume, and PI requirements appear in tenders that nobody described as design-and-construct.
The design responsibility you may be carrying without noticing:
- Temporary works. Shoring, trench support, falsework, formwork, propping, temporary traffic arrangements and site access are generally your design responsibility even on construct-only contracts, and they are frequently required to be certified by a qualified engineer.
- Contractor-proposed alternatives. Any value engineering or alternative method you offer transfers design responsibility for that element to you.
- Erosion and sediment control design. Frequently a contractor deliverable rather than a designer deliverable.
- Traffic management design. Traffic guidance schemes and traffic management plans carry professional responsibility and, in several jurisdictions, must be prepared by a qualified person — see our guide to traffic management plans and traffic guidance schemes.
- Mix designs and product selection where the specification sets a performance requirement rather than a prescriptive one.
Where PI is required, $5 million to $10 million is the usual range for the SME band, and Victoria’s Construction Supplier Register sets $5 million for works categories.[3] Two features of PI cover matter more than the limit. It is written on a claims-made basis, meaning the policy that responds is the one in force when the claim is made, not when the work was done. And that in turn creates the need for run-off cover — continuing PI after you stop performing that type of work, or after the business winds up, for as long as claims may still emerge. Contract requirements to maintain PI for a period of years after completion are common, and they cannot be satisfied retrospectively.
Environmental impairment liability
General liability policies typically respond to sudden and accidental pollution events and exclude gradual pollution. Civil work generates both, and the gradual variety — sediment-laden runoff over weeks, hydrocarbon seepage from plant, dust deposition, disturbance of previously contaminated ground — is precisely the category most likely to produce a regulatory notice and a clean-up cost.
Environmental impairment liability, sometimes written as pollution legal liability, is the specific answer. It is not universally required in tenders, but it is increasingly requested where the work involves watercourses, potentially contaminated land, sensitive receptors, or scopes with a known contamination risk such as asbestos cement main renewal or former industrial sites. For contractors working in remediation and contaminated land it is a standing requirement rather than an occasional one.
The commercial reason to take this seriously has little to do with the tender’s insurance schedule. Environmental obligations on civil contracts are backed by statutory penalties that sit outside the contract, and the controls you commit to in your environmental returnable are the controls a regulator will hold you to. Our guide to the construction environmental management plan covers what that document must contain; the insurance question is what happens when the controls fail.
Principal-arranged insurance: what it does not do
On some government work the principal arranges contract works and public liability insurance for the project rather than requiring the contractor to do so. Several jurisdictions run standing programs of this kind. Tasmania’s principal-arranged contract works and public liability arrangement is a useful published example of the structure: cover provided by a named underwriter, applying to contracts up to a stated contract value ceiling, with a third-party legal liability limit of $20 million, and with a defined list of project types that must be referred to the principal’s broker for individual terms rather than being automatically covered.[12]
That referral list repays close attention, because it reads like a list of civil scopes. Road construction including tunnels, pipelines, micro tunnelling and horizontal directional drilling, underground works, breakwaters, dams and weirs, flood repair works, existing property, and wet risks where more than twenty per cent of the contract value is in, on or over water are all identified as project types requiring referral.[12] In other words, much of the work an SME civil contractor performs does not sit inside the automatic cover — it requires specific terms to be arranged.
Where principal-arranged insurance does apply, four things remain true.
- You still need your own liability and plant cover. A contractor working under a principal-arranged program still requires its own liability cover and plant cover for exposures the project policy does not pick up.[4] Your operations away from the site, your plant, and your activities outside the insured works are yours.
- You still need workers compensation. It is never part of a principal-arranged program because it is a statutory scheme obligation of the employer.
- The excess is a live question. Contract works excesses under principal-arranged programs are frequently allocated to the contractor by the contract, whether or not the contractor arranged the cover. Establish who bears it and at what level before you price, because on a modest contract the excess can exceed the margin.
- Read the interaction, not just the two policies. The point of failure in dual-insurance arrangements is the seam between them, and the seam is defined by the contract rather than by either policy.
The indemnity clause your policy will not answer
This is the most serious mismatch in the whole subject and it is almost never raised at tender stage.
A public liability policy covers your legal liability — liability the law imposes on you. It does not necessarily cover liability you have assumed by contract beyond what the law would impose.[13] Many liability policies contain a contractual liability exclusion which, read strictly, removes cover for contractual liabilities arising from contracts you enter with customers or suppliers.[8] Indemnities assumed by contract for which a contractor would not ordinarily be liable are generally treated as a commercial undertaking on the contractor’s part rather than an insurable one.[9]
Now consider what government and council civil contracts routinely require. Broad indemnities in favour of the principal. Indemnities extending to consequential loss. Obligations to indemnify irrespective of the principal’s own contribution to the loss. Assumption of responsibility for damage to the principal’s existing assets. Liability for third-party claims arising from the works generally rather than from your negligence specifically.
Each of those pushes your obligation beyond what the law would impose, and each of them therefore sits — potentially — outside your policy. The consequence is that a contractor can be fully compliant with the tender’s insurance requirements and simultaneously carry a substantial uninsured exposure created by the same contract’s indemnity clause.
There is no neat solution, but there is a correct process, and it is a three-way conversation rather than a two-way one:
- Identify the indemnity and risk-allocation clauses at tender stage, not at contract execution. On a standard form, these are known clauses. On an amended standard form or a bespoke council contract, they need reading.
- Put them to your broker with the specific question: does my policy respond to this obligation, and if not, what is available?
- Where cover is not available, price the retained risk or depart. A stated departure in the tender is a legitimate commercial position. Silent acceptance of an uninsurable indemnity is not a strategy.
This is also the point at which insurance stops being an administrative item and becomes a go/no-go input. A contract whose indemnity regime is uninsurable at your scale is a contract to decline, and our go/no-go framework should carry it.
Subcontractor insurance: your obligation, your exposure
Whether your policy extends to subcontractors working on your behalf depends entirely on the wording. Some policies extend cover to declared subcontractors; others exclude subcontractor activities.[6] Contract works policies differ on whether subcontractors are automatically included.[2] Neither is safe to assume, and the assumption is common.
As head contractor on government civil work you generally carry three separate obligations here: to ensure your subcontractors hold their own cover at appropriate limits, to verify it, and to keep verifying it as policies renew mid-contract. The practical minimum discipline:
- Specify required covers and limits in the subcontract, aligned to what the head contract requires of you rather than to a generic figure.
- Collect certificates of currency before site access, not after.
- Record expiry dates in the same register that tracks your own, and re-collect on renewal. A subcontractor’s policy lapsing mid-contract is your problem.
- Confirm with your broker how your own policy interacts with subcontractor exposure — specifically, whether it responds if a subcontractor’s cover fails.[6]
Where labour hire is used, the interaction with the worker-to-worker excess discussed earlier becomes directly relevant, and it is worth pricing.
Certificates of currency: what evaluators actually check
The evidence, not the cover, is what fails at tender. What an evaluator checks is narrow and mechanical, which is precisely why it should never be failed.
| Check | The common failure |
|---|---|
| Is the document a certificate of currency? | A policy schedule, renewal notice, invoice or broker email is submitted instead. Tender documents ask for a certificate of currency; supply exactly that |
| Is it in date at the closing date? | Expired certificates. The single most common avoidable exclusion in civil tendering |
| Does it extend past the contract period? | A certificate valid at tender but expiring mid-contract. Where it does, state the renewal date and confirm the cover will be maintained |
| Is the insured entity the tendering entity? | Cover held by a related company, a trustee, a former name, or the operating entity where a different entity is tendering. Group structures cause this constantly |
| Is the limit at or above the stated requirement? | A limit below requirement, or an aggregate limit where per-occurrence was specified |
| Does the description of activities match the work? | An insured business description that does not encompass the tendered scope — the quiet failure, because it passes the tender check and fails the claim |
The entity question deserves emphasis because it is a structural rather than administrative error. If you tender as one entity and insure as another, you have a compliance failure at tender and a coverage problem afterwards. Where a group structure is genuinely required, the certificate must name the tendering entity as an insured, and a broker can arrange that.
The systemic fix is a compliance cabinet with an expiry register — every certificate, licence, registration and certification, with expiry dates, reviewed monthly. It is dull, it takes an hour a month, and it eliminates an entire category of loss. Our guide to building a tender content library sets out how to structure one, and our list of common tender mistakes explains why compliance failures cost more work than weak writing does.
Pricing insurance into the bid
Insurance is a real cost of government work and it is systematically under-recovered by SMEs, usually because annual policy premiums are absorbed into overhead and never allocated against the contracts that drive them.
The costs that belong in a bid:
- Project-specific contract works premium where the cover is placed per project rather than under an annual policy.
- The incremental cost of any uplift the tender requires — a higher public liability limit, an endorsement for depth or vibration, environmental impairment cover, or PI where design responsibility has been transferred.
- Retained excesses, including the differentiated excess for underground services and the worker-to-worker excess, priced as an expected cost rather than ignored as a contingency.
- Existing structures cover where a renewal scope requires it.
- Hired-in plant cover and hiring charges extensions for the plant the job actually requires.
- The administrative time to collect and verify subcontractor certificates and maintain currency through the contract.
Two disciplines make this recoverable. First, allocate your annual premiums across expected turnover to get a defensible percentage-of-contract insurance cost, and carry it as a line in your pricing model rather than as a rounding item. Second, and more importantly, read the insurance and indemnity requirements during the tender period rather than after award. That is the only window in which an uplift can be quoted by a broker, priced into the bid, and either recovered or used as a reason to decline. Our guide to pricing strategies for government tenders deals with the wider compliance cost stack this belongs to.
Where to start
A practical sequence, in the order that removes the most risk for the least effort:
- Build the expiry register. Every certificate, licence and certification, with expiry dates, reviewed monthly. This eliminates the largest single category of avoidable tender exclusion and takes an afternoon to establish.
- Confirm the insured entity on every policy matches the entity you tender as. A structural error, cheaper to find now than at award.
- Take your actual policy wordings to a broker who understands civil work and ask specifically about underground services, depth limits, vibration and removal of support, care custody and control, the part being worked upon, asbestos, and the worker-to-worker excess. Ask what is excluded, what is sublimited, and what is conditional on site procedures.
- Reconcile your policy conditions against your own documents. If cover for underground services is conditional on service location records, your WHS management plan, methodology and site procedures must all describe a process you actually follow.
- Map where design responsibility sits in the work you bid — temporary works, ESCP, traffic management, alternatives — and decide whether professional indemnity is genuinely optional for you.
- Read the indemnity clause on your next three tenders and put each to your broker. This is where the uninsured exposure lives.
- Price it. Allocate premiums against turnover, carry insurance as a real line item, and quote uplifts during the tender period rather than absorbing them after award.
The framing that helps most: the tender’s insurance schedule is a compliance test, and passing it is necessary and insufficient. The question worth answering is not whether you meet the limit, but whether the policy behind the certificate would answer the claim your specific scope of work is most likely to generate. On civil work, the honest answer is often no — and finding that out during the tender period is considerably cheaper than finding it out afterwards. What happens when the claim actually arrives — notice, evidence and the renewal consequence — is covered in our guide to making an insurance claim on a civil job.
All limits, ranges and examples in this guide are illustrative and drawn from published sources at the date of writing. Insurance requirements are set by the individual tender and contract, and policy wordings differ materially between insurers. This guide is general information and not insurance, legal or financial advice; obtain advice from a licensed broker on your own circumstances before relying on any figure here.
- Industry standards for civil SMEs synthesised from Australian state prequalification scheme guidelines and tender conditions: $20 million public liability as the de facto standard for road authority and significant council work, $10 million sometimes accepted for smaller council and subcontract work, compulsory state-based workers compensation, professional indemnity of $5–10 million where design is in scope, and contract works, mobile plant, motor vehicle and environmental impairment as commercial essentials sized to the project. Insurance minimums are rarely specified at the prequalification stage — they appear in the tender documents and the contract. $20 million public liability is described as the standard minimum across the major eastern-seaboard state schemes, with workers compensation mandatory in all jurisdictions and professional indemnity required where design, engineering or advisory services form part of the scope. Confirm the specific requirement against each tender. ↩ ↩ ↩
- Australian insurance broking guidance on contract works and construction all risks cover: every standard form major works contract in Australian use obliges the builder to arrange and maintain insurance on the works for at least the contract sum plus a margin, and failure to comply is usually a ground for termination or suspension of payment; insure for the full contract value plus an allowance of at least ten per cent for variations and professional fees, together with an amount for debris removal; underinsurance can trigger average clauses which reduce claim payments in proportion to the level of underinsurance; most policies cease at practical completion, handover or when the owner occupies the works, whichever occurs first; either structure can be labelled Contract Works or CAR by the insurer, so the schedule should be reviewed rather than the product name; and whether subcontractors are automatically included and whether principal-supplied materials are covered differ between insurers. ↩ ↩ ↩ ↩ ↩ ↩ ↩ ↩
- Victorian Construction Supplier Register requirements as summarised in Australian prequalification guidance — professional indemnity of $5 million required for works categories; professional indemnity generally required where the contractor carries any design responsibility.

- Australian construction insurance broking guidance — most Australian construction work is let under a standard-form contract, commonly AS 4000 (general conditions of contract), AS 2124 (its older but still-used predecessor) or AS 4300 (design and construct), each containing an insurance clause setting out who insures the works and which parties are to be covered; contracts usually require the principal, and sometimes subcontractors and financiers, to be noted on the contract works policy so they hold an insurable interest; contract works is first-party material damage cover on the works themselves while public liability is a separate third-party policy; and a contractor working under a principal-arranged program still needs its own liability and plant cover for exposures the project policy does not pick up. ↩ ↩ ↩ ↩
- Australian earthmoving and civil insurance broking guidance — differentiated excesses apply to specific civil exposures, with the excess for damage to underground services a commonly negotiated item; and some insurers impose a separate “worker to worker” injury excess of up to $50,000, most commonly in the range of $10,000 to $25,000, where a claim is made for injury to a labour hire worker or another contractor on site. ↩ ↩
- Australian civil construction insurance broking guidance — many standard public liability policies include an underground services exclusion, or apply cover subject to conditions such as requiring prior service location records before excavation, and contractors should confirm whether the policy responds to underground services claims and under what conditions before excavation begins; whether a policy extends to subcontractors working on the insured’s behalf depends on the wording, with some policies extending cover to declared subcontractors and others excluding subcontractor activities entirely; best practice is to require all subcontractors to hold their own public liability insurance and to confirm how the head policy interacts with subcontractor exposure on each project. ↩ ↩ ↩
- Australian construction insurance guidance on contract works and liability policy features — vibration, removal or weakening of support is triggered by work near existing structures, with some policies excluding it outright and others providing it up to a sublimit or subject to specific conditions; hot works including welding, cutting and grinding are typically subject to conditions including fire watchers and permit requirements; and contract works cover responds to physical damage to the works during the construction period, materials and equipment awaiting installation on site, and temporary works including formwork and scaffolding. ↩ ↩ ↩
- Australian contractor insurance guidance — insurers commonly exclude asbestos work, hot works, working at heights above certain limits and underground services damage unless endorsements are purchased; it is common for a business liability policy to exclude work beyond one or two metres in depth, to impose height restrictions, to exclude damage to underground infrastructure, or to decline cover in undisclosed circumstances such as mine sites or work on water or electrical civil infrastructure; policies may include depth limitations often capped at ten metres without endorsement; claims from striking underground cables, gas lines, water mains or data infrastructure during excavation can readily exceed $50,000 and some policies impose significant excess conditions for this type of damage; and contractual liability exclusions generally mean most policies do not cover contractual liabilities arising from contracts entered into with customers or suppliers. ↩ ↩ ↩ ↩
- Australian insurance broking analysis of cover for existing structures — public liability policies generally contain an exclusion relating to the “part being worked immediately upon”, which is exposed to broad interpretation; exposure to liability for vibration, weakening or the removal of support is excluded by many policies or requires the risk to be quantified and added; insuring existing structures for their entire value or on a first-loss basis under a material damage policy removes the onus on an insured to prove legal liability, mitigates the liability exclusion for the part being worked immediately upon, essentially renders obsolete the exclusion for vibration, weakening and removal of support damage to existing structures, mitigates the issue of owner’s own damage, and mitigates some contractual indemnity requirements which may not ordinarily also be legal requirements; a common material damage exclusion applies where loss results from fault, error or defect in workmanship, design or material; where any existing structure in whole or part passes into the care, custody or control of the contractor, appropriate sum insured allowances must be made and specific policy terms relating to care, custody or control must be taken into account; and indemnities assumed by contract for which a contractor would not ordinarily be liable are generally considered an entrepreneurial or commercial-risk undertaking on the contractor’s part. ↩ ↩ ↩ ↩ ↩ ↩ ↩
- Analysis of Victorian building practitioners’ insurance requirements under the applicable Ministerial Order — the required policy must not contain terms which exclude cover by reason of claims in respect of personal injury or property damage having arisen directly or indirectly from, or having been caused by or in connection with, the erection, demolition, alteration of or addition to buildings or temporary structures by or on behalf of the insured, or any vibration, or any removal or weakening of support caused thereby. This requirement applies to registered building practitioners under the Victorian scheme and is cited here as a contrast, not as a requirement applying to civil contracting. ↩
- Gilbert + Tobin — Modernised, but familiar: key changes to AS 4000:2025 explained (Standards Australia released the updated AS 4000 General Conditions of Contract on 30 June 2025; the update keeps the core structure of the 1997 edition while introducing changes reflecting current legislation, industry practice and drafting standards, including provisions responding to the Personal Property Securities Act 2009 (Cth), the GST regime, harmonised WHS laws and digital communication). ↩
- Tasmanian Government Purchasing — Annexure to Fact Sheet: 2025–26 Principal-arranged contract works and public liability insurance (cover provided by a named underwriter; the Policy covers contracts with a contract value up to a stated ceiling; the third party legal liability limit provided by the Policy is $20,000,000; project types to be referred to the Principal’s insurance broker to determine appropriate terms and a premium rate include road construction including tunnels, tunnels — new — road, rail or pedestrian, pipelines — new, micro tunnelling and horizontal drilling, underground works, breakwater, dams including weirs, flood repair works, existing property, insolvency projects, mining, offshore risks, inland rivers, power transmission lines and power generation, and wet risks where over twenty per cent of contract value is in, on or over water). Cited as a published example of the principal-arranged structure; terms are jurisdiction- and year-specific and must be confirmed against the current arrangement. ↩ ↩
- Australian construction insurance guidance on contractual liability — standard liability policies cover the insured’s legal liability but not necessarily liability assumed by contract beyond what the law would impose; vibration and removal of support is often excluded from standard liability policies or subject to sublimits and specific conditions; and most policies impose conditions around locating services before excavation which site procedures must satisfy. ↩
