Correspondence V 1 P ctIpha COMMUNITY DEVELOPMENT July 12, 2006 RECEIVED Steve Yurecko Windridge Homes JUL 1 7 2006 11401 NW Skyline Blvd. CITY OF TIGARD Portland, Oregon 97231 BUILDING DIVISION Re: Tigard Plan Review MST2006 -00101 Dear Mr. Yurecko: We have once again reviewed the letter from the city of Tigard regarding the plan check comments by Dan Nelson dated June 5, 2006. As you are aware, we were originally directed to provide calculations and drawings prior to the joist and truss manufacturer's layouts, and that the joist and truss manufacturer would comply with the structural drawings. Our initial response to the plan check comments was consistent with the above directive. At your request, we have now revised the structural drawings and calculations to comply with the joist and truss manufacturer's layouts and will reply to the plan check comments as such. Included with this letter are 3 sets of revised calculations and revised structural drawing sheets S2, S3 & S4 for both lots 9 & 13. The enclosed calculation pages are intended to replace ALL of the original calculation pages GI through G32 with the enclosed pages GI through G65. The calculation revisions include all necessary changes to match the floor joist and truss layouts. Also included are calculations for every beam, as ° requested. Please note, several modifications will need to be made to the joist manufacturer's layout. Attached with this letter is figure 1, which details the required changes. We respond to the plan check comments as follows: E ° Item 2: Drawings have been revised to match truss manufacturer's layout. See revised sheets S2, S3 & S4. Item 3: Drawings have been coordinated with the joist manufacturer's ° layout. However, as stated above, several modifications will need to be made to the joist manufacturer's layout. Please have the joist manufacturer modify there layout as per figure 1 and the revised structural drawings sheets S2, S3 & S4. 501 NE Hood Avenue, Suite 310, Gresham, Oregon 97030 [T] 503- 489 -1803 [F] 503- 489 -1843 Item 6: See Item 3. Item 7: See calculation pages G3, G5 & G9 for beam numbers & locations. Sincerely, ALPHA COMMUNITY DEVELOPMENT r A•vvw � Steven J.

We respond as follows. Item 1: Please have the appropriate entity add an additional section cut on the plans as indicated by City of Tigard. (By Others) Item 2: It is our understanding the truss & joist manufacturer will revise there layout and analysis to comply with S3 & S4 of the structural drawings. Item 3: Joist manufacturer to match the beam sizes as indicated on S3. Item 4: We have revised the S2 sheet to include the location of the holddown anchors. Attached are three stamped copies of the revised S2 sheet. Item 5: Please refer to the revised S3 sheet included with this letter. We have added an additional note and detail as requested. 0 Item 6: We have reviewed the structural drawings and did not find any discrepancies between the architectural floor plans and the structural drawing set. Please have the joist and truss manufacturer review their drawings to match the architectural floor plans and all structural information within the stamped structural drawing set, sheets Si through S6. If it is determined there are differences between the architectural floor plans and the structural plans, please specify the location and we ° will update our drawings accordingly. Item 7: All beams have been grouped and named according to size and then assigned an individual number. For example, we have grouped together all 3.5 x 11.785 LVL beams and titled the group as 3.5 x 11.875 LVL to avoid confusion. Group designations and locations for beams are shown on calculation sheets G2, G4 & G8. The beam number 501 NE Hood Avenue, Suite 310, Gresham, Oregon 97030 [T] 503 489 - 1803 [F] 503- 489 -1843 • corresponding to each individual beam is located on sheets G3, G5 & G9. The Woodworks software, which we use for our wood design, automatically identifies the most critical member for each group and summarizes its findings on G1 of our calculations. For example, under the "Critical members and design criteria" table on G1 of the calculations, the program has identified member b39 as the most critical beam of the 3.5x1 1.875LVL group. We therefore provide a calculation of each of these critical members. In the case of b39, the calculation is listed on calc sheet G20. Typically we do not provide calculations for the remaining "non- critical" beams within each group as we've already shown the worse -case beam is satisfactory, unless requested. Item 8: The shearwall was analyzed and designed as a 2' -4.5" wide shearwall; however the detail incorrectly reads 3' -1.5 ". We have revised detail 9/S6 to match the foundation plan. Please see the attached copy of the revised structural sheet S6. Sincerely, ALPHA COMMUNITY DEVELOPMENT Steven J.
