If you own or develop large construction projects in California, your insurance spend is bigger than you probably think. It’s hidden inside every subcontractor’s bid, marked up, and duplicated dozens of times across the job site. This article shows you exactly how an Owner-Controlled Insurance Program (OCIP) recaptures that money, with real numbers and examples, so you can see whether a wrap-up makes financial sense for your next project. It’s written for owners, developers, and project managers running builds large enough that insurance becomes a line item worth optimizing.

Key takeaways

  • An OCIP typically saves 1% to 4% of total construction costs, which on a $200 million project means $2 million to $8 million.
  • Savings come from buying insurance in bulk once, instead of paying every contractor’s marked-up, duplicated premiums.
  • OCIPs also cut claims costs through centralized safety programs and a single carrier handling every dispute.
  • The savings are not automatic; they depend on proper setup, accurate insurance-cost “back-out” from bids, and experienced administration.
  • Kavana Insurance designs and administers OCIPs for California owners and developers to capture those savings cleanly.

Where the money is hiding

On a traditional construction project, every contractor and subcontractor carries their own general liability and workers’ compensation insurance. They build the cost of that coverage into their bid, add overhead and profit on top of it, and pass the whole marked-up figure to you. Multiply that across 30 or 40 trades and you are paying for insurance many times over, with a margin stacked on each layer.

An OCIP flips the model. Instead of every contractor insuring themselves, the project owner buys one master policy that covers everyone enrolled on the job. According to Davis Wright Tremaine’s analysis of wrap-up programs, an OCIP bundles workers’ compensation, commercial general liability, contractor’s pollution liability, and umbrella/excess coverage into a single consolidated program. Buying once, in volume, eliminates the duplication and the layered markups.

The first source of savings: bulk buying and bid back-out

Here is the mechanism that drives most of the savings. When an OCIP is in place, each contractor must remove the cost of insurance from their bid, since the owner is now providing that coverage. Brown & Brown explains that contractors normally fold insurance, profit, and overhead into their bids, so stripping the insurance line out produces an immediate, measurable reduction in what the owner pays.

The consensus figure across the industry is a savings of 1% to 4% of total construction costs. Multiple brokers put the range at 2% to 4% for well-run programs. To make that concrete:

Project sizeSavings at 1%Savings at 4%
$50 million$500,000$2 million
$100 million$1 million$4 million
$200 million$2 million$8 million
$500 million$5 million$20 million

On a $200 million California office tower, a 3% savings is $6 million returned to the project budget – money that would otherwise have disappeared into contractor markups.

The second source: bigger limits for less

OCIPs don’t just cost less; they often buy more coverage per dollar. Because the owner is purchasing limits for the entire project at once, the buying power is enormous. Davis Wright Tremaine notes that subcontractors who might individually carry only $1 million or $2 million in limits can be covered for $25 million under a single OCIP.

That matters financially in two ways. First, you get catastrophic-loss protection that individual subcontractor policies could never provide. Second, you stop paying for redundant limits – 40 separate policies all carrying their own (inadequate) limits is far less efficient than one program with deep, shared limits.

The third source: fewer, cheaper claims

The savings aren’t only on premiums. A well-run OCIP lowers the cost of claims over the life of the project, and on a multi-year build that adds up fast.

With a single carrier and a single safety program covering everyone, there’s no finger-pointing between insurers when something goes wrong. Doug Esposito’s wrap-up analysis points out that wrap-ups improve safety outcomes, eliminate coverage gaps, and reduce litigation – all of which drive down the total cost of risk. Fewer disputes mean fewer legal bills and faster resolutions.

Consider a workers’ compensation claim under the two models. In a traditional setup, an injured worker’s claim runs through their employer’s carrier, which may differ from the GC’s and the owner’s carriers, inviting cross-claims. Under an OCIP, that same injury is handled by one carrier under one policy. In the Bay Area office-tower example we’ve used before, that single-carrier structure resolved a concrete subcontractor’s claim in six weeks instead of the six months a multi-carrier dispute would have taken – saving both money and schedule. 

A worked example: the $180 million development

Let’s put real numbers to it. A California developer is building a $180 million mixed-use project with 35 subcontractors.

Traditional model. Each subcontractor carries its own insurance and builds roughly 2% of its contract value into its bid as insurance cost, plus overhead and profit on top. Across the project, the owner ends up paying an estimated $4.5 million in stacked, marked-up insurance costs baked into the bids.

OCIP model. The owner buys one master program for an estimated $3 million in premium, and requires every subcontractor to back the insurance cost out of their bids. Net result: roughly $1.5 million in direct savings – about 0.8% of project cost – before counting the claims-cost reductions and the value of higher limits. With a cleaner safety record and fewer litigated claims over the build, the developer’s total savings climb toward the 2–3% range by project close.

The lesson in the numbers: the premium you pay for the OCIP is smaller than the sum of what every contractor would have charged you for their own coverage – and that’s before the indirect savings.

Why the savings aren’t automatic

OCIPs are powerful, but the benefits depend entirely on execution. Doug Esposito’s analysis is blunt on this point: wrap-up benefits are not automatic and require experienced administration, careful policy review, proper insurance-credit methodology, and attention to state-specific rules. A few things that make or break the savings:

  • Accurate bid back-out. If contractors don’t truly remove their insurance costs from their bids, you pay twice. Tight contract language and audits are essential.
  • Right project size. Most California carriers want a sizable construction value for an OCIP to pencil out. Brokers commonly cite a $50 million-plus threshold for owner wrap-ups, with mega-project economics improving as size grows.
  • Disciplined administration. Enrollment tracking, payroll audits, and carrier reporting all have to be managed correctly, or the program leaks money.

How Kavana Insurance helps you capture the savings

Kavana Insurance designs and administers OCIPs for California owners and developers, with more than 20 years of experience in complex construction risk. We model the savings before you commit, write the contract language that ensures contractors actually back insurance costs out of their bids, and handle the enrollment, audits, and claims so the program delivers what it promises. Because we work with hundreds of carriers, we shop your project across the market to secure the lowest premium for the limits you need.

Conclusion

The math behind OCIP savings is straightforward: buy insurance once, in bulk, instead of paying every contractor’s marked-up, duplicated premiums – then layer on lower claims costs and bigger limits. On a large California project, that routinely returns 1% to 4% of total construction cost to your budget, which can mean millions of dollars. But those savings only materialize with proper setup and disciplined administration.

If you’re planning a project north of $50 million, it’s worth running the numbers before you default to the traditional model. Reach out to Kavana Insurance today and we’ll model the potential savings for your specific build.
