Plans n Subject: Liebreich Residence By /A Date �' (9- // Modifications to residence UTF Job Number: 11 -004 T �T Dear Mr. Weeks: REVISION � lb ! r i This office was asked to modify the plans to add a, new bonus /storage room at the upper . level that was previously a lower roof. This included modifying the upper floor plan, A'' roof trusses and framing, as well as the upper floor framing. Attached are the revisions to those plans, as well as the revised elevation. Also, a further analysis was necessary to determine if the upper floor framing was still adequate with the additional floor loading. It was determined through analysis that the upper floor framing, specifically over the garage as previously designed and specified is adequate. One additional 5 1/8" X 15" glulam will be required under the upper level floor plans. We have also concluded that no additional lateral supports were needed, as the wind loading did not increase, and there was a minimal and insignificant increase in seismic weight. As specified above, and as drawn on the attached drawings, we conclude that the general framing of the structure is sufficient to adequately support the new addition, with the new beam and modified framing as shown. If you have any questions please do not hesitate to contact this office. OFFICE COPY Respectfully, - 4. UTF Consulting •` r , ? O t' } Geoffrey . right, 4s7 ' ' Principal G014 Encl.
