We have used 503.1.1, as discussed, which allows us to use Type IIB as our construction type. This then changes all of our values in Table 601 to be 0's. 2. The box for ESFR has been un- checked as we have learned from the sprinkler providers that you cannot have an ESFR system over 40 feet. We have discussed all of this with Dale Coffey, City of Newton Fire Dept. and have added smoke and heat vents according to the Fire Prevention Codes. I have provided a drawing showing the number and location of those vents. P ig 76, y3. The 3 hr. firewall as described is non -load bearing. There will be no unprotected openings when complete. I don't think the existing firewall has to project above the roof, based on 1 or 2 of the exceptions in 705.6 and also under 705.6.1 stepped roofs. X 4. We will provide the engineered rack drawings as soon as possible. However, as you suggested, I am attaching the structural design portion of Appendix B for those drawings. 5. The card readers only restrict persons from entering a space without the use of an access card. Once in the space, you or anyone else can exit the space unrestricted. The card is not required for exit. When the exit device is pushed it releases the lock and allows unrestricted passage out. 6. The Statement of Special Inspections is attached to this submittal. i Member of the American Institute of Architects • National Council of Architectural Registration Boards Certified r i f Thank you for your time reviewing our project. Please call if you have any further questions or concerns. Sincerely, J. Stan Winstead, AIA Sales (800) 614 -4162 th mmim Customer Service (800) 659 -1342 Leading Manufacturer of Structural Steel Storage Systems James, The appendix B information you asked for is attached. A few of The items are not filled in due to the explanation from Dan Clapp, the Structural engineer for Frazier. If you have any additional questions for Mr. Clapp feel free to call him. Stan - I understand the blocks that you are suggesting we fill in, however, those apply to building construction not rack supported building construction. The wind shear will vary across the rack structure with the exterior frames taking a very different shear than the interior frames. Further, in the down -aisle direction the wind shear will be distributed to all the rack columns and is generally not a design consideration. The Basic Structural System is a 'Rack- Supported Building ", in accordance with the specific seismic requirements as spelled out in the RMI Specification (RMI /ANSI MH16.1- 2008). The seismic base shear also varies across the building just like the wind shear. In a rack - supported building the lateral design is controlled by three factors - Wind, Seismic and Stability. Different parts of the structure are governed by different factors. For instance the exterior frame horizontal and diagonal braces may be governed by the wind forces while the interior frame braces may be governed by the seismic requirements. I trust this is the information you require. If you have any further questions feel free to call me.
