Umbrella Policy

In Plain English

Extra liability insurance that sits on top of your other policies and pays when those limits run out.

Definition

An umbrella policy provides additional liability coverage above the limits of multiple underlying policies—such as CGL, auto liability, and employer's liability—and may also fill gaps where the underlying policy does not respond. Unlike excess liability, an umbrella policy can drop down to provide primary coverage for uncovered claims that exceed the underlying policy's retention. Large construction projects frequently require contractors to carry $5–$25 million umbrella limits.

Why It Matters in Bidding

Owner and GC contracts routinely set required umbrella or excess limits, and a bidder who cannot meet them may be deemed non-responsive regardless of price. Estimators should confirm the required limits early, since the annual premium is a real overhead cost that must be recovered through markup, and stacking higher limits for a single large project can materially affect the bid.

Example

Reviewing the insurance requirements in the bid documents, a subcontractor sees a $10 million umbrella limit required, confirms with their broker that their current $5 million policy can be increased in time, and folds the added premium into their overhead before submitting.

Frequently Asked Questions

Required limits vary widely by project size and owner risk tolerance, from a few million dollars on smaller jobs to much higher figures on large or high-risk work. The contract or front-end specifications state the exact amount. Bidders should verify the requirement during bidding and confirm their broker can provide compliant limits and certificates.
Excess liability simply adds limits over a specific underlying policy and follows its terms. An umbrella also adds limits but can broaden coverage and, in some cases, drop down to act as primary for claims the underlying policy excludes. Contract language and the policy itself determine how it actually responds.
Yes, indirectly. The premium for required umbrella limits is part of a contractor's general overhead, which is recovered through markup spread across jobs. When a single project demands higher limits than the contractor normally carries, the incremental premium should be considered in that bid's pricing.
