Your plan notes that you will be sheathing the entire <br /> exterior of the building with OSB permitting the use of Table R602.10.4 Continuous Sheathing Methods,CS-WSP,CS- <br /> PF and PFH. Note that braced wall lines 3 and 6 are braced with bracing method GB. <br /> The attached sheets, BP 1,BP-2 and BP-3 indicate the locations of braced wall segments and the location of portal frames. <br /> See Details Si, S2 and S3. <br /> The sportcourt cannot comply with the prescriptive bracing requirements of the Minnesota State Building Code so an <br /> engineered solution is provided. See Details SW 1 and SW2. <br /> You also asked that I review the tall wall at the sport court. Frame the exterior walls of the sport court indicated on your <br /> Lower Floor Plan as walkout foundation walls with(2)2X6s#2 SPF @ 12"centers,the exterior walls indicated over <br /> foundation Look Out walls with(1)2X6#2 SPF @ 12"centers and over the foundation walls indicated as Full Height frame <br /> with(1)2X6#2 SPF @ 16"centers. <br /> You asked me to comment on the tall wall framing at the exterior wall of the stairwell on the front/right elevation. Please see <br /> Detail T1. <br /> A basic assumption of IRC bracing is that the rest of the structure is properly constructed and connected per the appropriate <br /> section of the code. Please note IRC Figures R602.10.8(1)and R602.10.8(2)Braced Wall Panel...to Floor/Ceiling <br /> Framing connection requirements for the continuous method(attached). <br /> The information and opinions contained herein are based upon the limited investigation described at the beginning of this <br /> report.No warranties are expressed or implied regarding the existence of other unknown conditions not specifically <br /> addressed.Our work is in accordance with generally accepted engineering standards and is not intended to be relied upon or <br /> transferred to individuals other than the addressee.
