Flag explanation

Section 1606.2 as amended requires that the actual weights of fixed equipment be used for design dead load purposes. RTU-1's stated operating weight (3,200 lb) exceeds the 2,000 lb concentrated point load that beam BM-7 was actually designed for, meaning the structural design does not reflect the actual weight of the fixed equipment as required by this provision. The beam design must be revised or verified to accommodate the actual equipment weight before the unit is ordered or set.

Project clause '1':
1. RTU-1 is a 5-ton packaged rooftop unit located over Grid B3, with an operating weight of 3,200 lb including curb and rigging. This weight should be checked against the structural engineer's roof beam design at this location (see S-101, beam BM-7) before the unit is
ordered or set -- BM-7 is currently designed for a 2,000 lb concentrated point load at this location, which is less than RTU-1's stated operating weight.

The provisions of Section 1510 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.
