The high exit signs will be added under the T.I. permit as the exits may <br />change as tenant improvements get developed. <br />B. The exit sign notes under the legend on sheet AN-1 was updated to include this information. <br />3. The following comments should be addressed for the Door Plan 3/A0.4: <br />A. The minimum 18-inch side clearance should be dimensioned. <br />B. The plan appears to show that a ramp may begin within 5 feet of the building face. Ramps are required to <br />include a minimum 5-foot landing at doors. The landing may overlap with the maneuvering clearance, but <br />not the door swing. The plan should show a minimum 5-foot clearance from the end of the door in its fully <br />open position to the start of ramps. See IBC Section 1101.2 and ICC 117.1-09 Section 405.7.5. <br />RESPONSE: <br />A. A dimension has been added to detail 3/A0.4 noting the 18" clear dimension. <br />B. Detail 3/A0.4 is not intended to depict a ramp condition. The locations of detail 3/A0.4 are called out on <br />the site plan (A0.1) by keynote 4. Therefore this condition does not apply. <br />4. Sheet AN-0 states that the component performance method of WSEC-15 Section C402.1.5 was used, and <br />specifies a minimum thermal rating for the roll -up doors of R=17.5. However, Sheet AN-0 indicates the <br />thermal rating should not exceed U=0.057. The stated R-value appears to be the inverse of the calculated U- <br />value. This relationship is generally not correct for composite systems. Documentation should be submitted <br />substantiating doors rated at R=17.5 will have a maximum rating of U=0.057. Alternatively, Sheet AN-0 may <br />be revised to require a maximum rating of U=0.057, or the calculation may be revised. <br />RESPONSE: <br />4. The value listed on the cover sheet was changed to require a max U-value of 0.057. <br />STRUCTURAL: <br />1. Structural and geotechnical special inspections are required for this project. A statement on special <br />inspections is provided in the "Statement of Special Inspections" section of the General Notes on Sheet 51.0. <br />The statement should include a table listing each type of special inspection and should specify the extent of <br />each inspection (e.g., continuous, periodic) per IBC Section 1704.3.1. The table should include special <br />requirements for seismic and wind resisting systems as required by IBC Sections 1704.3.2 and 1704.3.3, <br />respectively. See IBC Sections 107.1,1704.2.3 and 1704.3. <br />RESPONSE: Please see response letter from Shutler Consulting Engineers Inc. <br />
