Attention: John Thoresen, contact person Sent via e-mail FROM: Ann Bullis, Building Official RE: Plan Check: 2008-0463, 0464, 0465 Project: Sunset 100 LP Mixed Use Project Address: 121, 123, 125 Sunset Ave N During the re -review of the above noted project, it was found that the following issues still need to be addressed. We have redlined some minor issues to help keep things moving forward, but the items below still must be addressed and revised plan sheets provided accordingly. Please provide written responses to each comment as to how it has been addressed and where changes can be found on the plans. Please resubmit revised plans to Marie Harrison, Senior Permit Coordinator for this project. 1. Previous Item 6: Details 6 & 8 on Sheet A13 now reference an STC of 50 or more (IBC 1207), but as noted in the past comments, the listed and tested assemblies referenced (UL V471 & G512) did not include sound testing. Provide the sound testing documentation for these assemblies. 2. Previous Item 10: Coordinate new detail 11/A13 with structural detail requested by the City's structural consultant (see structural comment 427). Clearly show how fire rating will be maintained. Currently the detail shows sheetrock between the joist Danger and shearwall. 3. Previous Item 11: The construction supporting vertical and horizontal fire rated assemblies must be protected to the same fire rating. Notes are provided on the plans that generally state this, but no listed and tested assembly details for fire rated beams and columns could be found on the plans. Please provide to fully address this issue. This was previously discussed with the architect. 4. Previous Item 15: On Sheet Fl, clarify where the duct penetrations will terminate to the exterior of the building for all three mechanical rooms on the garage level. See IBC 716.6 for duct penetrations of horizontal assemblies and limitations. As shown, the duct penetrations do not meet the exception to IBC 716.6.1 (must meet all items in exception). A 2 -hour shaft will be required at each location. Also, if the ducts are routed as shown on the plans, the shaft will affect the stairways. This issue still needs to be addressed. 5. Previous Item 30: The datum point must still be provided with an elevation (on which height calculations are based) and be Iabeled. 6. Previous Item 33: Special inspection Agreements must still be submitted. 7. A separate permit is required for the trash enclosure located on the adjacent property. The adjacent property owner must apply for and obtain the permit, or provide a letter from the adjacent property owner authorizing you to act as their agent on this issue and apply for and obtain the permit on their behalf. Please contact Marie Harrison to apply for the permit. See attached structural comments from the City's consultant. Please have your engineer contact him directly if he has questions regarding his review comments. Eagle Eye Consulting Engineers, P.S.

SCOPE OF REVIEW Page 2 of 6 Plan Review Number 02 EECE#: EDM 08-55 (2) Sunset 100, LP 2008-0463 The scope of this review is for the Structural, only requirements of this project. All features were checked only to the extent allowed by the submittals provided. All portions of this project are assumed to meet or will meet other departmental requirements, conditions and concerns before permit approval. STRUCTURAL COMMENTS General 1. EOR, the analysis uses a steel stud wall to resist the lateral forces in plane. Out of plane analysis has be submitted but not in -plane for shear wall resisting element. Please submit this upon the response. 2. 44. Engineer of Record (EOR), the geotechnical report is a preliminary report not the final report. Please submit the final report upon the response. The response state the owner shall provide, but this was not provided. Please submit this upon the response. 3. The new design analysis submitted on sheet page 51 shows the member failed. EOR, please clarify upon the response how the forces will be resisted and submit analysis to justify. 4. 48. The analysis state this is a two way PT slab but there are banded tendons in one -direction and distributive tendons in the other directions. A two slab is where distributive the one are spaced in both directions. Please justify upon the response how it was determined to be a two way PT slab. The new analysis submitted only has the output and not the input. Please submit the complete the input in order to complete the review. 5. 49. The design analysis for the PT slab only has three sheet of floor plan diagram output printed. Please submit the complete input and output analysis of the PT slab upon the response. In addition, it is not clear what PT program has been used. When resubmitting please verify the current ACI 318-05 has been used in the design of the PT slab. The response states please see Rain concept Output. But the input used in the analysis is required to be submitted in order to complete the review. There is no way to complete the review without this. Please resubmit this upon the response. 6. 50. EOR, the structures are attached with a stairway without considering lateral effect due to this. Please submit analysis of effect of the lateral loads on the stairway or provide some type of separations. ASCE 7-05 12.12.3. Submit analysis to show the stairway are independent of the structures. Currently there is no separation shown. Page 3 of 6 Plan Review Number 02 EECE#: EDM 08-55 (2) Sunset 100, LP 2008-0463 Sheet S 1.1 Structural Notes 7. 51. Continuous special inspection is required for the installation of the stud rails. Please add this to the inspections schedule. ESR -2494. The response states stud rails are not used but the analysis submitted state stud rails are required. In addition, sheet 52.3 clearly state studs rails are to be used at the column on grid 4. Please modify analysis and drawings accordingly. Sheet S 1.2 Structural Notes No comment for this sheet at this time Sheet S 1.3 Structural Notes No comment for this sheet at this time Sheet S2.1 Foundations Plan 8. 56 FOR, please submit analysis for the pile cap specified on this sheet. This appears not to be addressed in the analysis submitted. The response state see sheets P1 -P5 but this was not in the submitted analysis. Please submit this upon the response in order to complete the review. Sheet 52.2 Post Tension Plan 9. 57. The minimum clear of bonded reinforcement steel for post tension concrete shall not be less than I". This sheet shows CGS of the slab at 1". Please modify design and analysis to maintain a 3 -hour lid. IBC table 720.1.. The design analyses submitted still have the CGS at 1" but the drawings state 1.25 at the mid span. Resubmit PT analysis for the CGS shown on this sheet.. 10. 58. FOR, drop panels or stud rails are required for the slab system at the columns due to shear loads. There are stud rail details on sheet 55.2 but the stud rails are not specified on any of the slab plans. Please modify accordingly. ACT 421.1 R- 08. The analysis submitted state stud rails required or drop panel are required. However, the response state studs are not to be used. See Reinforcement SSR plan 41. 11. 59. FOR, please provide the tendon profile at the opening in the slab and submit analysis to transfer this force around openings. ACI -05 18.2.3.. EOR, provide analysis at the corner of the opening of the PT slab to resist the design forces. This still has not been provided at this time. The opening at the stairway is required to show the profile at the corner. There is not a concrete wall at this location. A tendon profile is required to be specified at this locations Also the Page 4 of 6 Plan Review Number 02 EECE#: EDM 08-55 (2) Sunset 100, LP 2008-0463 opening South of grid C and a little to the East of grid 2 analysis at this locations should be provided. I was unable to determine this form the submitted information. 12. EOR, the tendon profile specified on this sheet does not inatch the analysis submitted. Please clarify upon the response and submit analysis for the tendon profile specified. Sheet 52.3 Mild Steel Plan 13. EOR, please adjust the text between grid 3 and grid 4 near the opening in the slab in order to read the requirements. The text over laps and it is unreadable to see what is required. 14. 61. EOR, it appear the top reinforcement does not match page PT -3. For example at the stair, or at the perimeter, etc. Please modify accordingly or clarify upon the response why this does not match the analysis submitted. The reinforcement specified on this sheet does not match the analysis submitted. For example, the analysis state 32 45 top but this is not specified on the drawings between grid 3 and grid 4. Please modify the analysis or the drawings accordingly. Sheet 52.4 Second Floor Framing Plan 15. 63. EOR, please specify the required collector elements for the horizontal diaphragm on this level to drag the forces into the interior shear walls. The response state see revised plan but there appear not to be any collector elements nor the required nailing specified on the drawings. Please clearly show the requirements for the collector elements to transfer the lateral horizontal diaphragm forces to the vertical resisting elements. 16. 64. EOR, please provide a detail for how the beam marls BM3 is connected to the tube steel post/beam. Nothing is specified at this time. EOR, please submit analysis for the cantilever beamm. The connections and alternate span loading shall also be considered. Base off the back span the uplift forces appear not to be resisted. Please clarify upon the response. 17. EOR, the detail at the 2 -hour separation wall 1/56.2 appears not to be an assembly for 2 hours. Please modify the detail and submit analysis to maintain the required separations. This is required at grid C and 2. Please clarify how the rated assemblies will be maintained. A UL number, ICC report number or IBC approved rated assembly shall be used. Please modify accordingly.
