Revised design analysis submitted has a restrained retaining wall but the drawings do not reflect any retaining wall or details. Please clarify upon the response. Page 11 A. 2. Please submit the design professional's stamp and signature for the Pro -built guard rails. 3. Engineer of Record (EOR), it appear the accidental torsion force was not applied to the horizontal diaphragm resisting elements. Please clarify upon the response. ASCE 12.3.1.1 & ASCE 12.8.4.2 4. The Metwood building solutions design analysis package submitted, during this review cycle, was not stamped by a licensed professional in the state of Washington. Since the framing is not prescriptive per the IRC then stamped documents are required. (the shop drawings were stamped by Jason M Conn and he is also required to stamp the analysis for his portion of the design) S. In the design analysis per intertek on page, 27 of 79 show the member are "bad". Please clarify why this is the case and revised analysis and drawings accordingly. 6. 1. Please submit an analysis for the web crippling as noted in the Metwood truss analysis. The analysis stamped by Jason M. Conn state web crippling will be checked manually. Please submit this upon the response. The analysis submitted used AISA-2001 spec. Reference and standards of IBC 2006 shall be 2004 and not 2001. Please resubmit or clarify upon the response why older code was used. IBC chapter 3 S 7. 2. There was not any lateral analysis for the Metwood building solutions. All that was submitted was the gravity analysis of the beams. Please submit this upon the response. IBC 1604.2. The response states `see revised letter from SDA attached'. However, there was not any analysis for the lateral load transfer for the diaphragm load as required. Details and analysis are required to be submitted. Also, the new analysis submitted states the lower floor dead load to be 12 psf. Please clarify how this was determined when the floor system will exceed this. Please revise and modify as required upon the response. 8. 3. Please submit lateral design for the ICFpanelize system used. This was not in the submitted information. IBC 1604.2. This appears not to be addressed at this time. Please clarify upon the response. Page 3 of 7 Plan Review Number 2 EECE 09-07 Tiegs 2009-0316 9. 5. EOR, please justify the plate height used in the analysis for the main floor. Based off the building sections the plate height used of IO feet appears to be lower then the sections specify. Please resubmit or modify drawings accordingly. The response states to see attached letter but no letter was submitted. Please clarify upon the response. 10. 6. EOR, please justify the plate height used in the analysis for the Upper floor. Based off the building sections the plate height used of 8 feet appears to be lower then the sections specify. Please clarify upon the response and resubmit or modify drawings accordingly. The response states to see attached letter but no letter was submitted. Please clarify upon the response. 11. 7. Please add to the drawings a statement of special inspections as required per 1705 and 1704.1. The responses states note added to structural notes. Please see sections 1705 for the items to be added to the drawings. It appears based off the revised submitted document this has not been addressed. IBC 1705 12. 10. EOR, the design analysis used "trib" height for the wall for the first floor of 9.5 and 4.75'. How was this determined? Based of the section cuts this appears not to be correct. Please clarify upon the response. It was not clear how this was addressed since there was not any letter from the EOR as per the response. 13. The drawings do not specify the thickness of the ICF walls. Please add this information to the drawings or clarify where this information is specified. 14. 15. For member BI from Metworks has an uplift load of 6.7 kips. Please clarify on the drawings how this force will be resisted. The response states inverted hanger but I was unable to find where this was specified in order to transfer the loads. Please clarify upon the response and modify drawings accordingly. 15. 16. EOR, there is a concrete column analysis but there is not any concrete column shown or detailed on the drawing. Please clarify upon the response. The response states `see letter from SDA' but there was not a letter in the submitted package. Please clarify upon the response. 16. 17. There are two lateral calculations that are different in the submitted analysis. One in the beginning of the analysis and one at the end use different heights and widths. They are not the same but they appear to be for the same part of the structures. For example, the A and B zone are different. Please clary the submit analysis upon the response with either a key or another way to distinguish where each portion applies to the structure. No letter was submitted for SDA. Please submit this upon the response. Page 4 of 7 Plan Review Number 2 EECE 09-07 Tiegs 2009-0316 Sheet A2.1 Upper Floor Plan 17. 19.

Please submit this upon the response. It was not clear where the analysis was provided. Please clarify upon the response. Sheet S2.1 Foundations Plan 18.22. EOR, please clarify the size and reinforcement for the footing mark 60 in order to complete the review. This is not on sheet S-2.0. EOR, the footing changed from 60 to a 48. Please submit an analysis for the footing to be smaller than on the originally submitted drawings. 19. 25. EOR, please provide a detail for the concrete column note on the foundations plan. Where is the steel to be placed? How are the vertical bars tied? Please modify the drawings to show the construction of the concrete column. ACI 7.10.5. This still has not been addressed. Grid 3A shows a concrete column without any supporting documents. Please submit and revise accordingly. Sheet S2.2 Upper Floor and Lower Roof Framing Plan 20. 26. EOR, the drawings only show three sided lateral vertical resisting elements. The analysis submitted has not accounted for this type of lateral resistance. Please resubmit analysis and modify the drawings to show how the horizontal lateral forces will be transferred. ASCE 12.14.7.4. Letter was not submitted to justify the thrce-sided diaphragm to resist the lateral design loads. Please submit this upon the response. SheetS3.1 Details 21. 30. Please provide a licensed design professional's stamp on this sheet. This is not conventional framing per the IRC and a design professional is required to stamp this sheet. IBC 106.1 The response states `now stamped by the EOR', but there is not a stamp on this sheet. Please submit this upon the response. Sheet S 1.0 Structural Notes 22.

Detail I & 2: Please clarify the size of the IFC hanger noted in the details to support the design loads. IBC 106.1.1. The design analysis submitted for the Metwood hanger states to use 7 -gage steel but the details state use 10 -gage. 10 gage thickness is .1345 and 7 -gage is .1793. Why are the drawing specifying smaller gage then required by analysis? Please clarify upon the response and modify accordingly. Sheet 4 of 9 METWOOD 29.40.
