Flag explanation

Section 1708.1 requires an engineering assessment (structural analysis and/or in-situ load test) whenever there is reasonable doubt about the strength, stability, or load-bearing capacity of an existing structure for expected loads. The project clause acknowledges that the original roof design documents are unavailable and that new point loads from mechanical equipment (including the 2,000 lb allowance for BM-7) cannot be verified, which constitutes exactly the kind of 'reasonable doubt' condition triggering the mandatory engineering assessment. Instead of performing or committing to the required structural analysis/in-situ load test, the clause merely proceeds with an assumed allowable pending future verification, which does not satisfy the code's requirement.

Project clause '8':
8. Existing roof structure to remain except as noted; new point loads from mechanical equipment require verification against the original roof design documents, which are not available for this building -- the 2,000 lb allowance noted above for BM-7 is an assumed allowable
pending that verification.

These candidates are local amendments to the national model building code (e.g. IBC), not the full code. You may draw on your own general knowledge of standard model-code provisions to judge whether the project clause is consistent with normal practice, but any conflict you report must be grounded in - and cite - one of the local amendment clauses shown above, since those are the only things a human reviewer can independently verify against this jurisdiction's actual adopted text.

Does the project clause conflict with or fail to meet any of these code requirements? Call report_conflicts with your findings, or an empty conflicts list if there's no real conflict.
