Aipedia: Structural and civil engineers
AI clash detection can find conflicts across federated BIM models quickly, but it does not decide who is responsible for resolving them or whether the design works. When a missed clash becomes a site problem, designers often end up in contribution disputes.
Part of: AI in structural and civil engineering
In short
On federated BIM models, AI tools now group and prioritise clashes, filter out false positives and check models against rules. They only test what is modelled and what the rules cover, and a clean report can hide unmodelled elements, tolerances or load paths. Part 2A reg 11K expects designers of part of a project to consider how their work relates to other design work. Collateral warranties widen the circle of people who can claim. PI usually responds to coordination failures alleged against the engineer, subject to the wording and to any net contribution clause.
Structural and civil engineers use AI-assisted tools to run clash detection between structure and services or architecture, cluster thousands of clashes into a manageable set, auto-dismiss clashes judged irrelevant, check model geometry against rules (for example minimum openings or cover zones), and summarise issues for coordination meetings. On large projects these tools make coordination practical. They also change who looks at what: dismissed clashes may never be seen by an engineer.
Model data raises its own questions. Federated models combine information from several firms, and AI tools may process them in the cloud. IStructE advises access controls, client permission before storing data and avoiding AI tools on sensitive projects such as hospitals, government buildings and critical national infrastructure, where model detail can itself be sensitive. Check the project's information requirements before switching on any AI feature.
Typical failures include an AI tool dismissing a clash as a duplicate when it is real, clash rules that ignore tolerances or fire protection thickness, elements not modelled at all (temporary works, fixings, builders' work holes), and federated models out of sync with the latest drawings. When the problem appears on site, each designer may say the coordinator should have caught it, while the coordinator says the clash was outside the agreed rules.
Illustrative scenario: an AI clash tool groups a services penetration through a transfer beam with minor clashes and marks it resolved. The beam is fabricated without the opening, and the contractor cuts a hole on site. Strengthening and delay costs follow, and the contractor claims against the structural engineer, who seeks a contribution from the services designer.
PI usually responds to an allegation that the engineer failed to coordinate or check with reasonable care. Contribution claims between designers are common in coordination disputes. Collateral warranties to funders, purchasers and tenants extend who can sue, and some contain obligations wider than the appointment, which PI may not mirror. Net contribution clauses can limit an engineer's share. Our guides on collateral warranties for consulting engineers and engineers' collateral warranty PII explain the issues. Cover is subject to the policy wording.

Apex arranges PI for consulting engineers working in BIM environments. A broker reviews your cover, collateral warranty terms and how your policy treats AI-assisted coordination.
The software supplier is rarely the answer for the client. Responsibility usually follows the appointment and BIM protocol: who was to coordinate, who designed each element, and whether each designer checked interfaces with reasonable care.
For primary structure, yes. Dismissed clashes are where real conflicts hide. Agree a review rule in the BIM protocol so an engineer sees any dismissed clash involving structural elements before it is closed.
IStructE advises avoiding AI tools on sensitive projects and names hospitals, government buildings, critical national infrastructure and NDA projects as examples. Check the client's security and information requirements first, and get written agreement before processing model data with any AI tool.
They let funders, purchasers and tenants claim directly, so a coordination error can generate several claims. Check that warranty terms match your appointment and that your PI is set up to respond to warranty claims.
