While comprehensive, SP-4 is not a substitute for engineering judgment. It is a guide to design, not a code itself (though it is mandated by reference in the International Building Code). It assumes the user has a basic understanding of statics and strength of materials. Furthermore, the document is heavily U.S.-centric (using imperial units and North American lumber standards), requiring careful conversion for international use.
