2950 Lone Oak Cir - Change of Construction ClassificationCraig Novaczyk From: Quinn Hutson [ghutson ©cnharch.com] Sent: Wednesday, November 24, 2010 9:21 AM To: Craig Novaczyk Subject: RE: 2950 Lone Oak Circle Attachments: Architectural Drawings R1.pdf Hi Craig, I looked at the area calculations and agree that changing the construction classification to Type IIB makes much more sense. I didn't originally do that because I knew that there was at least some wood construction in the existing offices. The change however will bring the building closer to the allowable areas if the building were to meet current IBC 2006 requirements. It is 17% over area for IIB under new codes; however, since this is an existing condition, would not need to be addressed at this time. Obviously, no change in use or addition would be allowed without addressing the allowable area with fire suppression or area separation fire walls. I have attached the revised plans in pdf format showing the new classification and changing the few new walls to metal stud. I will also drop off a set of revised plans around noon today. If you have any other suggestions or questions, please let me know. Thanks and Happy Thanksgiving! Quinn S. Hutson Quinn S.

Unfortunately, the plans that we have are lacking a code analysis. There are not any wall types listed either. The building was built of masonry and steel (in 1968) according to our records. Knowing these facts, I would ask that you work up a code analysis that supports the use of combustible construction for the walls in this remodeling proposal, or change the construction of the new walls to non combustible materials.
