Climactic and Geographic Design Criteria
Section R302.2 This section has been rewritten to allow for two one-hour fire-resistance-rated walls, called a “double wall” in the code. Thus, the previous amendment adding that provision to Section R302.2 is no longer needed.

Table R507.6 The portion of the table that identified the “maximum joist span” when used with a cantilever has been changed to “maximum cantilever”.
Mr. Schoenberg inquired whether further discussion should ensue regarding decks. Mr. Taralson stated that that the Inspections department would like recommendations from the Board. He furthered that the 2-ply sandwich beam has been allowed in Fargo as long as he could remember, with the exception of some changes to fasteners and tech screws. Mr. Taralson stated that there have been many issues regarding cantilevers over the years, where some decks were being overdesigned but did not comply because the code specified actual span. Mr. Hildebrand clarified that Mr. Taralson was referring to the cantilever on the joist and that working with the actual span would be preferred. Mr. Taralson stated that he would like the Board to review both the sandwich method and the cantilever issue. Mr. Schoenberg stated that the amendment to Section R507.5 should be fine as long as it specified that the joist must be one piece and cannot be spliced over the intermediate beam line. He furthered that the back span must be a certain length and that, by adding another beam line, the back span is shortened. He noted that this would be acceptable as long as the joist is one piece and goes from the cantilever to the house. Mr. Schoenberg inquired as to when the sandwich beam method had been removed from the code. Mr. Taralson stated that the method in question was never in the code, but has always been allowed in this and other surrounding jurisdictions in North Dakota. Mr. Schoenberg stated that if the City wanted to continue to allow the sandwich method, Table R507.5 regarding max post spacing, may have to be adjusted to allow that detail as there are no beams bearing on top of posts and all force is going through the bolts. Mr. Hildebrand inquired on the effect of two plies not being attached to one another. Mr. Schoenberg stated that, as long as the beams are connected to the joists, having them apart will not significantly affect the strength of them. Mr. Schoenberg stated that he would review this further but that Table R507.5 would have to be amended. Mr. Taralson inquired whether every span in the table might change. Mr. Schoenberg responded that the entire table would have to change. Mr. Dietrich inquired whether or not a larger bolt would be sufficient rather than changing the table, as the table us used by all contractors in the area and other jurisdictions also. Mr. Hildebrand stated that 1/2”galvanized bolts are currently being used in the field and that contractors are having success using them. Mr. Schoenberg stated that he would provide an opinion to staff. Further discussion ensued regarding the details of when the deck section entered the code book.
