Professional liability and AI in engineering design
The professional liability of an engineer for their design work is not reduced by the use of AI tools. An engineer who seals drawings produced with AI assistance is certifying that those drawings meet applicable professional standards — the certification applies to the final product, not the process by which it was produced. If an AI-generated structural design contains errors that cause a building failure, the engineer who certified the design carries the professional and legal liability, not the AI tool provider.
This liability framework has a practical implication: AI-generated design outputs must be reviewed with the same rigour as manually produced designs. The standard of review must be sufficient for the reviewer to identify errors in the AI's output — which requires both technical expertise in the domain and understanding of the AI tool's characteristic failure modes. An engineer who reviews AI-generated structural calculations by checking only that the numbers are internally consistent, without verifying the underlying assumptions and boundary conditions, has not provided adequate professional review.
Professional indemnity insurance and AI
Professional indemnity insurance for engineering and architectural practices was designed before AI-assisted design was common. Many standard PI policies contain exclusions or limitations that may be relevant to AI-generated work product — exclusions for computer programs or software errors, limitations on coverage for new or unproven technologies, or requirements that work product be the result of the insured's professional skill and judgement. Engineering firms deploying AI in design work should explicitly raise this with their PI insurer and obtain written confirmation of coverage. The cost of an uncovered PI claim from an AI design error is likely to be orders of magnitude greater than the cost of a PI policy review and any necessary endorsement.
