Even contractors without a design license often take on design-build, design-assist, value engineering, or delegated design responsibilities that create professional liability exposure. Errors in plans, specifications, or professional advice — whether they come from you, your design subs, or consultants you coordinate — can trigger claims a standard general liability policy may not fully address.
When contractors should consider professional liability:
You’re signing design-build or CM-at-risk contracts, or you’re providing constructability reviews, sequencing plans, or means-and-methods guidance the owner relies on for project decisions.
You subcontract design work to engineers or architects but stay contractually responsible for their performance in the owner’s eyes — your exposure doesn’t disappear just because someone else drew the plans.
You perform value engineering, select systems or products, or coordinate complex trades like MEP, structural components, or building envelopes, where an error could cause significant cost overruns or rework.
You work on high-stakes projects — healthcare facilities, data centers, public infrastructure — where even an alleged professional mistake can lead to large defense costs and delay claims.
How Liberty structures your protection: We combine contractors professional liability with pollution and protective coverage where it makes sense, sitting it alongside your GL, umbrella, and builder’s risk — so you’re protected even when you’re not “the designer” on paper but still carry professional exposure under the contract.
