IBC section 2303.4.11 answers your first question, and 2303.1.8.2 answers your second question. PT wood (or any wood for that matter) should only be above 19% MC if it will be allowed to dry on site during construction before being covered up in the wall. I think there are some technical requirements for what “field drying” really entails.
~~ Eli Grassley
I am working on a project in Texas using Southern Pine. The specifications note that all lumber except pressure-treated shall contain not more than 19% moisture content. My questions are:
· Does Southern Pine require pressure treatment for uses like ledgers bolted to concrete or masonry, sole plates, etc.?
· If yes, why do you suppose it would be exempt from the stated 19% moisture content limit?
