Mr. Brad Rzechula Leading Edge Construction, LLC Plan Check Number: B1803-029, First Review May 4, 2018 13. Building foundations are shown in Sections 8/S-3.1, 10/S-3.1, and 11/S-3.1. The following comments shall be addressed: a. Sections 10/S-3.1 and 11/S-3.1 are not specified on the Foundation Plan on Sheet S-3.0. The extent of all foundation sections shall be specified on the plan; unused sections should be removed from the drawings. See IBC Section 107.2.1. b. The sections shall specify the minimum required footing depth of 18 inches. See IBC Section 1809.5 Item 5. 14. Sections 10/S-3.1 and 11/S-3.1 specify vertical #5 reinforcement at 48-inch spacing for the full wall height. See IBC Section 1901.2. The reinforcement shall be revised based on the following: a. The areas of reinforcement is less than required by ACI 318-14 Table 11.6.1. b. The spacing or reinforcement exceeds the limit of Section 11.7.2.1. 15.The foundation plan on Sheet S-3.0 indicates the 8-foot tall foundation wall per Section 8/S-3.1 is the typical condition. The following comments should be addressed: a. The architectural elevations on Sheet 1-of-10 indicate the retained soil depth is less than one-half the first story height of 8 feet. Documentation verifying the retained soil depths for the project should be submitted for review. See IBC Section 107.2.1. b. The structural calculations for the 8-foot wall on page 26 appear to consider active soil pressures on the wall. The wall extends to and is restrained by the Main Level floor diaphragm. Calculations substantiating the design considering restrained-condition soil pressures shall be submitted for review. A minimum value of 60 pcf shall be used in the design unless a lower value is specified by the geotechnical engineer. See IBC Section 1610.1 and Table 1610.1. 16.The Wall Footing Schedule on Sheet S-3.0 specifies footing depths below-grade of 1 foot for both FW2- and FW3-type footings. The schedule shall clarify if this is measured to the top or bottom of the footing. If measured to the bottom of footing, the depth shall be increase to 18 inches. See IBC Section 1809.5 Item 5. 17.The foundation plan on Sheet S-3.0 references Detail 6/S3.1 showing a thickened slab-on- grade at the posts. The slab is identified as"by others"in Note 2/S-3.0, and is therefore not include in the design. The footing should be revised as an isolated footing. See IBC Section 107.2.1. 18.The foundation plan includes strip footings for the shear walls at Grid B/2 and B/4. Calculations substantiating the design of the footings to resist loads from the shear walls shall be submitted for review. The calculations shall demonstrate that the footings provide adequate strength and resistance to transfer overturning forces from the shear walls. See IBC Section 1604.1 and 1604.4. Gravity System: 19. Sheet S-4.0 appears to indicates that the Main Level floor framing is supported on Grid 3 by 8x8 wood posts. A connection between the posts and the beam should be specified.
