Construction insurance: how coverage attaches to projects, contracts, and companies

Two chassis: coverage that follows the company, coverage that follows the project

Construction insurance runs on two distinct chassis, and most confusion in the class comes from mixing them up. The first is the practice program: annual policies written on the firm itself — general liability, workers compensation, commercial auto, inland marine, umbrella — covering everything the company does across all of its jobs. The second is project-specific placement: policies written around a single job, term matched to the schedule, limits matched to that project’s values. Builders risk is the canonical example; wrap-up programs and project-specific general liability are the others.

The distinction decides who buys what, what your own policies respond to on a given site, how your premium audit treats each job’s payroll and receipts, and what the contract is actually asking for when its insurance exhibit lands on your desk. A two-person trade shop may go years touching only the practice side; a general contractor running concurrent commercial projects is managing both chassis on every job, simultaneously.

If you are still orienting on the practice program itself — which policies, who requires them — start with our contractor insurance guide. This one stays at the project and firm level: how coverage attaches to construction work, and how the architecture changes as the work scales.

Project-specific placements: builders risk, wrap-ups, and project GL

Builders risk is property insurance for the structure while it is being built: the limit is set to the completed value of the work, the term matched to the schedule, and coverage typically ends at occupancy or acceptance. It is the policy that pays when the half-framed building burns, and either the owner or the general contractor can buy it — a decision the construction contract should make explicitly. The mechanics, the exclusions that bite, and the renovation wrinkles are covered in depth in our builders risk guide; here it is enough to place it on the map as the project-side property chassis.

Wrap-ups are the project-side liability chassis. On larger projects, the owner (an OCIP — owner controlled insurance program) or the general contractor (a CCIP) purchases a single program covering every enrolled contractor on that project, typically general liability and often workers compensation, with dedicated limits and one carrier. Owners use wraps for coherent reasons: uniform coverage instead of sixty subcontractors’ sixty different policies, project limits other jobs cannot erode, centralized claims and safety programs, and fewer cross-party lawsuits inside the project team. For an enrolled subcontractor the effects run the other way: your own GL gets a wrap-up exclusion for that project, wrapped payroll and receipts are typically carved out of your exposure base at audit, and enrollment paperwork is a real task with deadlines.

The thing every wrapped contractor needs to hold onto: the wrap covers the project work, not your business. Tools, vehicles, off-site fabrication, and every unenrolled job stay on your own program — and telling your broker a job is wrapped before it starts, not at audit, is the difference between a clean carve-out and an argument. Project-specific general liability rounds out the project side: a standalone GL policy written for one job, used when a project’s risk or required limits do not fit the practice program, or to keep one large project’s claims from eroding the aggregate every other job depends on.

Contract requirements: how owner and lender paper flows downhill

Insurance requirements on a construction project flow downhill, and reading them in sequence explains most of what lands on a subcontractor’s desk. The lender sets minimum terms in the loan agreement — builders risk naming the lender, liability limits, sometimes flood — because the collateral is a half-built building. The owner passes those obligations into the prime contract with the GC, adding an indemnity clause and an insurance exhibit specifying limits, additional insured status, waivers of subrogation, and primary and noncontributory wording. The GC then flows the same structure down to every subcontractor, frequently adding margin — higher limits, per-project aggregates — so the paper it collects from subs is at least as strong as the paper it gave the owner.

The indemnity clause and the insurance exhibit are two halves of one risk transfer and should be read together before bidding, never after winning. The indemnity says who absorbs whose claims; the exhibit makes sure a policy stands behind the promise; and state anti-indemnity statutes limit how much of an upstream party’s own negligence a sub can lawfully absorb — limits that vary meaningfully by state. The endorsement mechanics that get a certificate past GC review are covered in our general liability guide; the project-level point is that none of it is negotiable in practice, and the leverage is in pricing the requirements into the bid and pre-building them into the program.

Certificates are how compliance is policed at every tier: a GC that cannot show the owner clean certificates from every sub has a contract problem, and a sub whose certificate fails review has a crew standing in the parking lot. Certificate discipline is the mechanism the whole project uses to verify the risk transfer actually exists.

Inland marine: equipment floaters, installation floaters, and property in motion

Construction property that is not the building itself lives on inland marine forms, because standard property policies are written for things that stay put and construction property never does. The contractors equipment floater covers the machines — excavators, skid steers, lifts, generators — usually scheduling the big iron individually and sweeping small tools under a blanket limit. The placement decisions that matter: valuation basis (replacement cost versus actual cash value on aging equipment), leased and rented equipment — leases obligate you to insure the lessor’s machine and name them, paper that is checked at claim time — rental reimbursement to keep a job moving while a covered machine is down, and equipment of others in your care.

The installation floater is the trade contractor’s analog to builders risk: it covers your materials and equipment destined for a project — from warehouse, through transit, on site, and once installed — until the work is accepted. A mechanical contractor with rooftop units staged for a Monday crane pick, an electrician with switchgear in a rented warehouse, a glazier with curtain wall in transit: that property is the installation floater’s job, and assuming the project’s builders risk covers it is a gamble on someone else’s policy, sublimits, and deductible. Trades carrying meaningful material values should control their own coverage.

Theft drives the loss frequency on both forms, and underwriters price the controls: secured yards, tracked equipment, serial-number inventories, and tool-checkout discipline that surfaces losses in days rather than at year-end.

Commercial auto: the fleet is where severity lives

Construction firms run vehicle-heavy operations — pickups, service bodies, dump trucks, trailers, the occasional low-boy — and commercial auto is where the catastrophic liability severity in the class increasingly concentrates. Jury verdicts in commercial vehicle cases have trended sharply upward for years, which is why underwriters scrutinize construction fleets harder than they used to and why contracts routinely require one million combined single limit with the umbrella above it.

The program decisions are concrete. Every vehicle and every regular driver belongs on the application as they actually operate — radius, cargo, who takes trucks home. Hired and non-owned auto coverage is mandatory in practice for any firm whose employees ever drive personal vehicles for work, because the employee’s personal policy may deny a business-use claim while the injured party names your company regardless. Trailers and the equipment they carry need coverage sorted deliberately between the auto policy and the inland marine floater before the low-boy rolls. And driver controls — MVR checks at hire and annually, a written phone and personal-use policy, telematics on larger fleets — are what keeps a construction fleet placeable at sane terms.

Pollution and professional: where design-build changes the program

Two exclusions in the standard general liability form matter enough in construction to drive their own placements. The pollution exclusion reaches ordinary jobsite events, not just Superfund scenarios: a ruptured fuel tank on an excavator, silt runoff reaching a creek, disturbed contaminants in a renovation, a refrigerant release. Contractors pollution liability (CPL) is the standard response — written for construction operations, available as a practice policy or per project, and increasingly required by owners on exactly the trades most likely to trigger the exclusion: earthwork, demolition, utilities, mechanical.

The professional services exclusion is the other. The moment a contractor takes on design responsibility — design-build delivery, delegated design, value-engineering a stamped detail — claims arising from the design itself fall outside the GL form, and contractors professional liability is the placement that responds. Design-build growth has pulled this into the mainstream of the class: a GC signing a design-build contract is warranting design it subcontracts to architects and engineers, and its own professional policy stands behind that warranty alongside the designers’ policies. Combined professional-and-pollution forms built for contractors often price efficiently; the screening question is simple — if the alleged error could live in the drawings, calculations, or specifications rather than the installation, GL is the wrong policy.

How the program scales from a two-person shop to a GC running concurrent projects

The same lines appear at every size; what changes is the architecture. A two-person trade shop runs entirely on the practice chassis: GL, commercial auto, a tools floater, workers comp where state law requires it, and a license bond — the work is keeping certificates clean and exposure data accurate. As the shop grows into commercial work, the contract-driven layer arrives: an umbrella to meet exhibit limits, blanket additional insured and waiver endorsements structured at bind, an experience mod that suddenly matters because GCs screen on it, and the first installation floater when staged material values get real.

A general contractor running multiple concurrent projects is operating a different machine. Subcontractor risk transfer becomes the core of the program — subcontract wording, flow-downs, and a certificate file that is actually enforced — because the GC’s own GL backstops every sub’s failure. Per-project aggregates stop being optional once several jobs share one policy year, builders risk becomes a per-project decision made at contract signing, wrap-up enrollment appears on larger work, and practice-level professional and pollution coverage joins as delivery methods demand. At the top of the range, a GC with enough concurrent volume starts evaluating whether to sponsor its own CCIP rather than keep paying for the margin in every sub’s individually placed coverage.

The throughline: rebuild the program deliberately at each step change in the operation rather than patching it. The most expensive construction programs we review grew by accretion — a shop-sized program with GC-sized exposure bolted on one endorsement at a time.

How Delegance structures construction programs

We place construction insurance as architecture, not a stack of quotes: practice program and project placements designed together, contract exhibits read against the policies before bids go in, wrapped work carved out cleanly at audit, and certificates issuing through the portal in seconds rather than broker phone tag. Coverage terms, sublimits, endorsement availability, and pricing vary by carrier and state and are always subject to underwriting.
