Engineer of Record (EOR), please submit the original geotechnical report for this remodel. The memoranda states to follow this report but it was not in the submitted package. Also, the general notes state site class E: IBC 104.11.1. The response states this will be provided by the architect. This was not submitted by the architect as per the response. Please submit this with the response. 2.3. Design analysis pipe piles from DCLU director rule.

The response states there is a soil report but this was not submitted with the response. Please submit this. 3.4. EOR, the design analysis states concrete on metal deck is fine to transfer the horizontal shear. How was this determined? Please submit the ICC report for the deck with concrete to transfer the required design force. IBC 1604.4. Calculations were not submitted to justify the deck would be able to transfer the lateral loads. Please submit an analysis to justify. Sheet S1.0 Structural Notes 4.8. EOR, please provide sections 01330 as noted under the steel joist sections 5200. IBC 106.1.1 The response states this has been changed to 1005 but the drawings do not reflect this. Please modify as per the response. 5.9. EOR, the ICC report for the steel decking is not per the IBC 2006 but the IBC 2000. Please provide current report for the current code. The ICC report is not per the adopted code. IBC 2000 is not the adopted code. Please provide an ICC report to the state adopted code (IBC 2006). Sheet S2.0 Foundation Plan 6.11. EOR, please provide an analysis for the new 6x6 post being added to the existing footing at enlarged plan 3. With the additional force being added to the existing footing, an analysis is required. IBC 106.1.1 IBC 108.1.2 This has not been addressed at this time. Please provide an analysis for the 6x6 post being added off center of the footing. 7.The architectural drawings show a 30” step. There are clearstory windows shown on architectural sheet A-4. This step in the roof and the opening is required also to be rated as per the ordinance comments for sheet A2. EOR, please revise accordingly. Page 3 of 4 Plan Review Number 2 EECE#: EDM 09-13 (2) Harbor Square Additions 2009-0530 Sheet S4 Roof Framing Plan 8.EOR, the architect shows clearstory window without structural support. Please provide details and analysis for the support of these windows. See west elevations on sheet A4. Sheet S6.0 Foundations Details 9.26. Detail 5: EOR, this detail is cut on sheet S5.0: Submit an analysis for the lateral loads to transfer for this connection. The X bracing at mid span would cause horizontal forces to be applied to be transferred to the base. Please clarify with an analysis how this transfer of force will be done. This was not in the submitted documents. The response states the members are well above the required. Please submit an analysis to justify. 10.29. Detail 8: EOR, please provide an analysis for the vertical load of the plinth being applied off center of the footing. This was not in the submitted package. IBC 1604.4. The response states the plinth is not drawn correctly and is only 2 feet tall. Modify the drawings to reflect this or note maximum height shall not exceed 2 feet. Sheet S7.0 Roof Framing Details 11.31. Detail 1,2,5,6,7,9,and 10; EOR please specify the required epoxy to be used for the connections of the bolt to the wall. I was unable to find where this was specified in order to check capacity. Also, submit an analysis to justify this epoxy will support the design loads. Also note if the fire rating {IIIA} of this building will not affect the epoxy used. Not all epoxies may be used in rated constructions. The response states all anchors are within the fire rated assembly but the architectural drawings do not reflect this. Please modify accordingly. Sheet S8.0 Roof Framing Details 12.35. Detail 6: EOR, please provide an analysis for the existing ledger to support the design loads. All that is noted is existing ledger without the size, bolts used, etc…. Sheet S4.0 has this section cut on the ‘Enlarged Roof Framing Plan’ but all that is stated is (E) 4X ledger. More information is required in order to verify this will support the design loads. EOR, this area is required to be 1-hour rated construction but the details do not reflect this. Please modify accordingly. See ordinance comment for the City of Edmonds. 13.38. Detail 12: EOR please provide torsion analysis for the curved beam shown in this detail.The response states torsion does not need to be addressed since it is not Page 4 of 4 Plan Review Number 2 EECE#: EDM 09-13 (2) Harbor Square Additions 2009-0530 large.
