You Should and Shall

Years ago, I went to a seminar about proper language included in Construction Documents... it was a lunch seminar. Somewhere between dessert and the 160 calorie chips, I may have forgotten it all. Going thru the b/w NFPA chapters, it clicked back again. When detailing, especially exterior envelopes IMHO, we shall note carefully. Don't just copy paste from another project, we should verify that the information still applies to the current project, weather conditions, and desired aesthetic outcome.

As NFPA clearly states:

3.2.3 Shall. Indicates a mandatory requirement.

3.2.4 Should. Indicates a recommendation or that which is advised but not required.

Happy detailing!
