6/11/2012 amended status per e-mail discussions: "OK for F&F".
.
1st Review: 5/17/2012 - Provide a response to comments along with revised plans. It may be helpful to shedule a meeting to discuss issues before making any changes or response. A 2hr or less meeting should be sufficient. Note: Since this initial review was done using reduced drawings items may have been missed or incorrectly interpreted and therefore new comments may be added to the 2nd review. I did not review in detail or verify compliance of all rated walls and assemblies. This will be responsibility of the architectural reviewer as part of IBC Chapters 6 & 7
1. Provide MOA approval letters signed by the "Fire Marshall and/or Building Official" allowing the design to be based on the 2006 code editions and allowing exiting design to be based on a single function use of the space rather than the entire building occupant load. See comments 2.
2. It appears that the calculated exit capacity for the main entrances does not take into account that both the auxillary/practice gym and the performance gym could be occuppied at the same time. There is no provision in the code that specifically allows this approach therefore it would have to be documented and approved by the building/fire official. Since these spaces share the main common entrance additional egress doors and width is required at both main entrances or an alternate means or MOA approval letter shall be submitted.
3. The egress barrier gates leading to the basement in stairs 4 & 5, level 1 appear to encroach into the stair/exit width. Stair 4 when fully open and Stair 5 during the swing. Verify the egress width is sufficient and is in accordance with IBC 1005.2. What is the actual width at these landings? The gate in Stair 4 could encroach upto 7 inches and the swing in Stair 5 shall not encroach more than 1/2 the required width. Please verify the numbers.
4. Due to the long narrow width of the main entrance/lobby this area appears to essentially be a corridor. The width at its narrowest point <19ft is insufficient to handle the expected/calculated occupants that are intended to egress through this area. I think that this condition relates to the overall exit capacity of the two main entrances.
5. Stair width requirements shall be based on the largest occupant load served. It is extremely difficult to verify this number due to the complexity of the egress layout. It appears that egress width at the landing of stairs 3 & 4 @ level 1 maybe obstructed/reduced. What is the required and actual width at the narrowest poing?
Please set up a meeting to go over and verify these numbers as well as other exiting concerns.
6. Provide a layout of fire extinguisher (FE) locations. One or two full size sheets of each level may suffice. It may be helpful to highlight each FE location for initial review. FE cabinets in rated walls shall be listed or the wall construction detailed to maintain the rating. FE's are required in each elevator equipment room per the elevator code.
7. Provide both the location of the required "Knox" box and the Bld Address. Show on elevation sheet.
8. Provide a revised door schedule showing hardware types and other missing info. All doors that require Panic or Fire Exit (Rated Panic) Hardware need to be noted as such on the door schedule sheet for verification during review & inspection. The door schedule sheet A711 seems incomplete as main vestibule and stair doors are not included. Based on the info provided a thorough door review could not be accomplished since there are missing doors and door types on the schedule such as 4070A & B, OH1, 1255A & B, 1245C, 1000G thru J, etc. If possible provide a list or all electrical rooms or at least all electrical rooms that require panic hardware per IBC 1008.1.10.
Note: Mezzanine area F corridor 4070 shows most doors as 60 minute to include restrooms. Door 4075 to the small closet is not rated. Why or why not?
9. It appears the combined occupant load of rooms 1270, 1275, 1280 & concession stand is > 50. Door 1280A requires the door swing to be reversed, panic hardware and exit signs to be added to both exit doors 1280A & B.
10. Provide occupant load signage as required for each assembly area. Show locations on plans. It might be easier to include this info on a separate sheet showing each specific assembly room & corresponding occupant load before making final changes to drawings.
11. On sheet A232 the space between doors 3025A & B is less than 4 ft and therefore does not meet IBC 1008.1.8.
12. Provide an exit sign at stair 3 - Door 153B & Stair 4 - Door 154B to prevent exiting back into the building through doors 153A & 154A. (Sheet E215 & E211)
13. Add an exit sign at the 2nd required exit from Fitness Room 1290 sheet E212 door 1290B &
14. The code study Sheet A020 references the building height as 90 ft & also does not classify the structure as a high rise. What is the 90 ft height actually pertain to? Is this ceiling height from the playing floor, roof height from lowest fire department vehicle access, an error in the drawings, or some other reference? If this is height to the roof it appears there is no affect on the design.
15. Provide a cut sheet with testing verification for the 2 hr glass at the stair enclosure.
16. The roof garden on sheet A246 appears to be an assembly space. Provide an occupant load for the space. Add required panic hardware, exit signs, occupant load signage to the drawing. Acknowledge and include required fire alarm devices for this space in the fire alarm design submital.
17. Basement Electrical Room B1095 exit doors appear to encroach into the egress width of stair 3 entry doors and possibly corridor (sheet A206).
18. Closet 2017 is over 10 sf. Therefore at least one of the doors is required to be a minimum 32inches wide per IBC 1008.1.1. (Sheet A226 & A711).
19. Mezzanine meeting room 4005/6 (Seating Area) shows an occupant load of 102 based on table & chair factor. It doesn't appear to include the occupant load of storage rooms within this suite. ** - What is the space between coat rm 4009 & exit door 4005A? Is this some form of room divider? If the room is intended to be divided into two rooms based on the OL of 102 at least one on the spaces would contain >50 occupants by calculation and require two exits. See comment 20.
20. The occupant load calculation for the mezzanine area may be inaccurate. Sheet A024 shows the meeting room and each luxury suite OL's based on seat counts that are not matching up. The roof top garden uses a factor if 15sf but does not show a seating plan for table & chairs. It does not appear that the egress capacity is affected but the correct number will be needed for posting required occupant loads.
21. Will a fire pump be required to supply the sprinkler system. If yes it is required to be in a rated room. Provide location of fire pump room and details for rated walls, ceiling, doors, & other openings for ventilation etc? The emergency generator will require a seperate submital, review, & permit forwarded to the fire system plans reviewer, Mark Warren. the room or enclosure housing the generator is required to be equippped with a separate battery powered emergency light fixture. Please acknowledge or show on plans.
22. Is it your intent to use or provide turnstiles whether tempory or permanant for admitance to events. If yes show number & locations to ensure they do not interfere or reduce the required egress width/capacity.
Note: I am researching for a requirement that does not allow "Unoccuppied Spaces" such as Mechanical Room 3025 to exit directly into an exit enclosure. If you are aware of this please call to discuss. This was used and approved on an earlier project where the owner treated the boiler room as an occuppied space and was later questioned by OSHA and not allowed. I would like to avoid this conflict if applicable. When/if the specific code section is found a new comment will be added after discussion.
