Details shall be provided to clarify the construction. <br /> c. The proposed decking shall be specified. Fastener requirements between the decking and <br /> framing shall be specified. <br /> d. Calculations substantiating the design of the framing and connections shall be submitted for <br /> review. The design shall consider the live loads per IBC Table 1607.1 Item 30. <br /> e. Details for the connections between the existing construction (i.e., deck and house) and the <br /> new deck shall be included in the construction drawings. Where the new deck imparts <br /> additional loading to existing structures, calculations verifying the existing structures shall <br /> be submitted for review. <br /> Lateral System: <br /> 9. The deck appears intended to be fastened to the existing structure for lateral support. Details <br /> for the connections shall be included in the construction drawings. Calculations substantiating <br /> the capacity of the connections in both principal directions shall be submitted for review. <br /> Where connections support both gravity and lateral loading, the connections shall be designed <br /> for concurrent loading. See IBC Sections 1604.1, 1604.4, 1609.1,and 1613.1. <br /> Miscellaneous: <br /> 10.The project includes guards (i.e., handrails and supporting posts). The guards shall be <br /> designed to resist the loads per IBC Section 1607.8.1. Calculations substantiating the design <br /> shall be submitted for review. Details for the connections between the railing and posts, and <br /> the posts and supporting structure, shall be included in the construction drawings. Where posts <br /> connect to rim boards and stair stringers, additional calculations and details shall be provided to <br /> prevent torsion in the framing and develop the loads into the supporting framing. See IBC <br /> Sections 1603.1 and 1604.1. <br /> This review has been performed for general compliance with the building codes as adopted and <br /> amended by the state of Washington and the city of Everett.
