They are good for, 90 MPH wind if the following items are considered and used as specs for the window installation. • The sides of the windows must be 2-2x6 members that are balloon:Gamed from the first floor to th.e dormer gable lower framing or roof plate. O Cross headers on the smaller windows on the left of the large window shall include 3V inch header for wind support. 31A x 5'/2 inch Timberstrand.headers would be sufficient. • 3 V2 x 5'/z inch Tim,berstrands are correct for the large window openings as supporting cross members. • Ground level wind velocity reduction considered in this design. With this layout the structure will be structurally substantial and meet your code requirements. IBC2000. With these corrections, J approve the construction as structurally competent. I hereby certify that this letter report and/or specification has been.prepared by me or under my direct supervision and that I am a duly registered Professional Civil Engineer under the laws of the State of Minnesota. if you have any :further questions or if I can be of any further assistance,please do not hesatate,to„,phone or write.
