July 22, 2025

Essential Guide to Professional Liability Insurance for Architects and Engineers

In the architecture, engineering, and construction (AEC) industries, precision isn’t optional—it’s expected. But even the most detail-oriented professionals face risks that can’t always be controlled. That’s where professional liability insurance comes in.

At I.S.C.A., we specialize in helping AEC firms—from sole proprietors to multi-state operations—protect their reputation, financial stability, and client relationships with coverage that truly fits.

Why Professional Liability Insurance Matters
Unlike general liability policies, professional liability insurance (also known as errors and omissions or E&O insurance) covers the cost of defending against claims of negligence, design errors, or failure to meet contractual obligations. For architects, engineers, and land surveyors, a single claim can mean thousands in legal fees—even if the issue wasn’t your fault.

You’ve spent years building your expertise. A tailored professional liability policy helps ensure one project misstep doesn’t jeopardize your future.

What It Typically Covers

Your professional liability policy may include coverage for:
  • - Legal defense and court costs

  • - Alleged design or planning errors

  • - Missed deadlines or cost overruns

  • - Claims arising after project completion

  • - Breach of contract or negligence claims

With I.S.C.A., your policy is built around the work you actually do, ensuring the coverage reflects your risk—not a generic industry standard.

Tailored Coverage for AEC Firms

Not all policies are created equal. Our team works with architects, engineers, and land surveyors nationwide to craft custom insurance solutions that:

  • - Meet state licensing and contractual requirements

  • - Address specific project types and exposure levels

  • - Scale as your firm grows

Integrate with other essential policies like general liability and commercial auto

We also assist with annual reviews and renewals, ensuring your coverage evolves alongside your business.

When Should You Apply?

The best time to apply for professional liability insurance is before you need it. Many clients require proof of coverage before you can even bid on a job. Others may require specific limits or endorsements tailored to project scope.

Even if you’ve never faced a claim, having this policy in place offers peace of mind—and strengthens your business credibility.
