1 The sections and construction details in Details (1), (2), (3), (4) and (5), and Tables (1), (2), (3), , , and are intended to be representative and not all-inclusive. Adopting agencies are encouraged to add construction details and sections appropriate to their specific areas. Utilization of these tables should be correlated with local industry group practices and model code research recommendations. For SI: 1 inch = 25.4 mm.
