Page 2 of 5 EECE#: EDM 07-54 Zimmerlund Residence 2007-1039 STRUCTURAL COMMENTS General 1. The design analysis shows a member being overstressed. Please submit analysis for the member not to be overstressed and modify drawings accordingly. 2. Please note on the drawing that the bottom chord of the roof trusses shall be designed for a live load of 20 PSF. Table R301.5 3. Architect of Record (AOR), please submit analysis for the Beam U01 through U05. This was not in the submitted documents. 4. Design analysis state shear wall shall be P2-3 but this wall is overstressed. Please modify accordingly. 5. Design analysis appears not to have beam U10 and U11 design. Please note for beam U10 the beam is dropped and only will have a connection at the beam U08. Analysis must account for the unsupported compression zone based on the locations supported. Please modify accordingly. Sheet A4: Foundation Plan/ Main Floor Framing Plan 6. AOR, please specify the required footing under the post supporting the covered entry. Noting is specified at this time. Sheet A5: Main Floor Plan/ Upper Floor Framing 7. AOR, please specify the required connection of the 2X10 joist bearing on the dropped beam. I was unable to determine this from the drawings. 8. There is no information for the attachment of the deck ledger. Please add this information to the drawing. R502.2.2 9. AOR, please provide a detail for the connection of the beam marked UOI to U04. The joists have a depth of 9-112" and the beam (U01) the depth is 9". Since there is a different depth, a detail is required at these locations to show proper beam to beam connections. 10. AOR, please provide a detail for the connections of the U17 and U18 beam intersections at the 6X8 post diagonally. A detail is required at this location to assure complete code required load transfer. Please add this to the drawings. 11. AOR, Please clarify the post to beam connection for the 6X10 to the 8-3/4 GLB. Page 3 of 5 EECE#: EDM 07-54 Zimmerlund Residence 2007-1039 12.

Engineer of Record (EOR), please provide analysis and detail for the half wall to resist the code prescribed guardrail forces. 14. Please specify the required blocking in the floor diaphragm to transfer the shear wall forces where the exterior shear walls that intersect at the opeing in the floor diaphragm. The shear walls are P 1-4 and currently there is not any method to transfer these forces. Please modify accordingly. Sheet A8: Building Sections 15. EOR please provide analysis for the 2x6 hem -fir #2 exterior stud walls to support the design loads for 18 foot clear span. (Also note there are window openings in this wall that must be accounted for) The code requires the maximum unsupported height to not exceed 10 feet unless analysis is submitted to justify. Sheet S 1: Lateral/ Shear Walls 16. The drawings specify a P2-2 shear wall but this wall is not shown in the shear wall schedule. Please modify accordingly. 17. The design analysis shear wall requirements appear not match analysis. Please modify accordingly. 18. EOR, please verify location of the hold downs shown on the main floor shear wall & hardware plan. Hold downs shall be placed at each end of the shear wall. Currently the diagonal wall shows the hold down on the interior of the wall. Please clarify on the response. 19. EOR, please provide analysis to justify that the hold down is not required for the shear wall P1-4 at the opening in the floor diaphragm. Sheet S2: Lateral/ Details 20. Detail 14: This detail is being specified where the lateral shear force will exceed 150 pl£ Toe nailing can not be used to transfer forces that exceed this. Please modify accordingly. IBC 2305.1.4 ORDINANCE COMMENTS General Page 4 of 5 EECE#: EDM 07-54 Zimmerlund Residence 2007-1039 21. Please specify the required light activation at the top and bottom of the stairs, per R303.6.1. 22. Please note on the drawings the required fire blocking information on the drawings.
