Flag explanation

The project clause describes excavation to 3 feet (36 inches) below finished grade along column line 18 for a utility tie-in, but does not indicate that fencing has been provided around the excavation area. Per the local amendment adding Section 3304.3, excavation exceeding 30 inches in depth must meet guard requirements per Chapters 10 and 16, and any excavation within 5 feet of a walkway must be fenced with fencing at least 4 feet high, supported against wind collapse. Since the excavation depth (36 inches) exceeds the 30-inch threshold, the clause fails to address these fencing/guard requirements, creating a potential conflict if the trench is near a walkway and unfenced.

The provisions of Section 1804 of IBC are adopted by reference with the following modifications:

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.
