This email will serve as the review <br />letter. The comments below should be addressed. <br />Revised copies of the drawings and calculations may be emailed directly to me to expedite the process. An itemized <br />response letter stating how each comment has been addressed should be included with the drawing. <br />Comments <br />The following comments should be addressed for the drawings: <br />a. The drawing need to be sealed and signed by the WA state licensed professional engineer performing <br />the design. See IBC Section 107.1 and RCW 18.43. <br />b. Note 4 provides only a generic requirement for anchors. The make, model, and dimensions for the <br />required anchorage should be specified in the drawings. <br />c. The anchor embedment is specified as 1.75" versus the minimum 2.5" embedment per the <br />calculations. In addition, the embedment specified in the drawings should be increased to account for <br />the non-structural layer of stucco coating the brick. A minimum thickness of 1" should be assumed <br />unless the actual thickness is verified. <br />The calculations specify three anchors. However, the drawings depict only two anchors. It is noted that <br />Note 4 is not consistent with the drawing, nor does it indicate the placement/spacing of the anchors. <br />The drawing should correctly state that the base material is unreinforced masonry (i.e., brick), not <br />concrete. <br />The following comments should be addressed for the structural calculations: <br />a. Wind loads appear to have been performed per ASCE 7-16 Chapter 30 as referenced by Section <br />29.3.2. However, this is not allowed as the sign is not located at least 3 feet from the top and side of the <br />building. Note that the adjacent building cannot be considered in the side distance as this structure <br />occurs on a different lot and cannot be relied upon to provide shielding (e.g., building could be <br />demolished, etc.). Revised loads per Section 29.3.1 should be calculated. It is anticipated that the <br />loading will increase as the current calculation is relying on shielding to reduce the wind pressure. See <br />IBC Section 1609.1. <br />b. The sign weight is based on 10 psf unit value. Two layers of 1/8" steel will weight 10.2 psf. In addition, <br />the baffle has an estimated weight of 15 LBS. The sign also appears to have an additional interior panel <br />on the inside of each layer backing the lettering in the sign. All of these elements will substantially <br />increase the sign weight. The weight should be revised. <br />c. Revised combined loading calculations should be submitted for review. See IBC Section 1605.1; either <br />combination 16-4 (i.e., 1.2D+1.OW) or 16-12 (i.e., D+0.6W) should be used. The load combination <br />should be commensurate with the design method (i.e., LRFD or ASD) for the anchor capacity values. The <br />load combination should include concurrent tension (from moments) and shear (combined for greatest <br />effect) from both wind and dead loads. <br />
