Flag explanation

The project clause specifies an exit stair handrail height of 30" AFF measured vertically from the leading edge of the treads. Local amendments 5b625195-d0ea-4e0f-9073-f49c50580dfc and 6cf5148e-30d8-4931-bdc7-16fed0101474 require handrails/guards on open sides of stairs (including where a guard serves as a handrail) to be not less than 34 inches and not more than 38 inches measured vertically from a line connecting the leading edges of the treads. The noted 30" height falls below this required minimum of 34", conflicting with the applicable code range.

Project clause '6':
6. Exit stair handrail (Detail A-102.1): the exit stair handrail at the rear egress stair is noted at a height of 30" AFF, measured vertically from the leading edge of the stair treads. Confirm this height against the applicable handrail/guard height range for stairs before
installation; the height as noted appears low relative to the typical 34"-38" range used elsewhere in similar occupancies.

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.
