Real case: an industrial warehouse with no geotechnical study and no fire resistance justification for the structure

Anonymised real case. Industrial warehouse project in Extremadura. Audit with the D-LINIEX AI verifier.

In industrial construction, two things concentrate the bulk of the technical risk: how the structure bears on the ground and how it behaves in a fire. In this project, both were left unresolved in documentary terms.

The two findings that mattered most

1. Missing geotechnical study. The allowable bearing pressure of the ground was assumed without any study to support it (CTE DB-SE-C requires ground investigation). Sizing a foundation on an assumed value means building on an unverified hypothesis.
2. Fire resistance of the steel structure not justified. There was no appendix substantiating the required R 30/60/90/120 (CTE DB-SI 6). Steel loses load-bearing capacity as temperature rises; without justifying the protection, stability in a fire cannot be guaranteed.

On top of these, there were missing items: the design report, the calculation appendices, the specifications, the quality control plan and the health and safety study, as well as expansion joint details (relevant in long-span warehouses) and waterproofing of roof junctions.

How the technician made use of it

The report grouped the findings into blocks (structure, fire, planning, documentation) with the relevant standard for each. The technician set priorities: first the geotechnical study and the fire calculation —what blocks the visa approval and triggers liability—, then the rest of the file. Without the AI, that orderly sifting would have taken hours of cross-checking.
