Architects and engineers professional liability insurance
A design error, a missed specification or a construction failure traced back to your plans can bring claims against your practice and personal assets, often years after the project closes. We build programs for architects, engineers, surveyors and other design firms across the Pacific Northwest.

Design claims often surface years after completion
Professional liability, also called errors and omissions (E&O), is the foundation of protecting a design practice. Unlike general liability, which covers accidents, professional liability covers claims arising from your professional services. In the design professions, claims often emerge long after completion, when a building envelope fails, structural issues appear or latent defects surface, so coverage has to account for that long-tail exposure.
Core coverages for design professionals
Professional liability (E&O)
Claims alleging negligent acts, errors or omissions in your professional services, from design flaws to specification errors to project management failures. Typically written claims-made: coverage responds to claims made during the policy period, subject to the retroactive date.
- Design errors and omissions
- Specification defects
- Code compliance failures
- Cost estimation errors
- Project management negligence
- Defense costs and settlements
General liability
Third-party bodily injury and property damage from your business operations rather than your designs, such as office slip-and-falls or damage caused by employees at a job site.
- Premises liability (office visitors)
- Operations liability (job-site presence)
- Products liability
- Personal and advertising injury
- Medical payments
- Legal defense costs
Cyber liability
Design firms hold client data, proprietary designs and intellectual property. As work moves to BIM, cloud storage and digital collaboration, cyber coverage responds to breaches, ransomware and technology failures.
- Data breach response costs
- Client notification expenses
- Ransomware and extortion payments
- Business interruption from cyber events
- Regulatory fines and penalties
- Network security liability
Business property
Office space, furniture, computers, plotters and equipment, plus valuable papers coverage for the cost to recreate drawings, specifications and project documents if originals are destroyed.
- Office contents and equipment
- Computers and technology
- Valuable papers and records
- Business income / interruption
- Equipment breakdown
- Extra expense coverage
Understanding professional liability
A&E professional liability responds to claims that your designs, specifications, opinions and advice harmed a client or third party. Most policies are claims-made, covering claims made during the policy period, which matters when you change carriers or retire: you need continuous coverage for past work. The retroactive date sets how far back coverage reaches; ideally it goes back to when you first obtained coverage.
Key point: if you cancel a claims-made policy without buying tail coverage (an extended reporting period), you lose protection for all past work, even projects completed years ago. When changing carriers or retiring, secure tail coverage or confirm the new policy covers prior acts.
Professional liability covers: design errors and defects; specification mistakes; building code violations; cost overrun claims; delay and scheduling errors; construction observation failures; feasibility study errors; and defense costs, even when a claim is groundless.

How design claims happen
Illustrative examples of A&E claims, and the coverage that typically responds.
A foundation design failure
A structural engineer's foundation design proves inadequate for soil conditions. The building settles unevenly and needs foundation remediation.
Illustrative example. Real outcomes depend on the facts and your policy terms.
Contract terms that affect your coverage
Contracts that waive limitation of liability, require indemnification for others' negligence or impose design warranties can create uninsurable exposures. We don't provide legal advice, but we flag common problem areas and recommend legal review when needed. Careful contracts, documentation and scope definition reduce claims and can improve terms and pricing.
Indemnification
Broad indemnity can create uninsurable exposure.
Limitation of liability
Caps on liability protect against very large claims.
Insurance requirements
Match contract requirements to available coverage.
Scope definition
Clear scope prevents scope creep claims.
Standard of care
"Reasonable care" versus warranty language.
Statute of limitations
Contractual limits on claim timing.
Subconsultant terms
Flow-down provisions and certificates.
Document ownership
Intellectual property and reuse rights.
Common coverage gaps, and how to close them
Inadequate limits
Limits that haven't kept pace with project size and claim severity. Review annually against your largest projects; most established firms should carry at least $1M to $2M per claim / $2M to $4M aggregate.
Gaps when changing carriers
A new policy with a later retroactive date can leave past projects uninsured. Match your original retroactive date, or buy tail coverage from the old carrier.
No tail coverage at retirement
Claims-made policies stop covering past work unless tail coverage is bought. Budget for it in retirement or dissolution planning; multi-year tails typically cost 150 to 200% of the final annual premium.
Contractual liability
Broad indemnities, express warranties or waivers of limitation can create excluded exposures. Have contracts reviewed and negotiate problem provisions before signing.
Subconsultant gaps
Claims against a subconsultant's work can fall back on the prime. Require certificates with adequate limits and retroactive dates, consider additional insured status on their GL, and verify annually.
No cyber coverage
Client data, designs and project information stored digitally create exposures standard policies don't cover. Add cyber covering breach, ransomware, business interruption and network security liability.
