Use of more current codes for shop drawings
Use of more current codes for shop drawings
(OP)
How do others handle delegated engineered shop drawings done for more current codes than the structure was permitted under? It seems reasoable to use more current codes but in some situations the required design criteria has actually been reduced.
It doesn't feel prudent to reject them.

OBC 106.7.1 Design criteria. An alternative engineered design shall conform to the intent of the provisions of this code and shall provide an equivalent level of quality, strength, effectiveness, fire resistance, durability, and safety. Materials, equipment, or components shall be designed and installed in accordance with the manufacturer's installation instructions.
However, if the newer code relaxed something, I typically require the item be adjudicated.

The EOR does not have the right to blow off the applicable code (as adopted by the governing jurisdiction) and simply go with the newer code.
RE: Use of more current codes for shop drawings
There was another post on this topic a good while back. As was pointed out there, the city will specify a date of IBC/UBC to be used. In Chapter 35, IBC specifies a particular date of ASCE 7 to be used. Then the ASCE 7 specifies a particular date of other standards to be used. The problem is that each standard specifies other standards that are several years older, so going down two or three layers also means going back 10 years.
Motivation to use the newer standard might include uniformity of designs, use of computer programs referencing the newer editions, or clarity of newer editions.
