Plan reviewed for the installation of a new aboveground fire sprinkler system for a proposed large storage warehouse SHELL. The system is a 3,044 head NFPA 13 system designed with 7 different systems which are fed from 3 different risers that are independently fed from the fire main which connects all three (3) risers.

Each riser has a manifold which serves multiple systems. This is an Early Suppression Fast Response [ESFR] Automatic Fire Sprinkler System designed in accordance with NFPA 13 recommendations to protect Solid-Piled or Single/Double-Row Rack Storage of Class I-IV Commodities and Rack Storage of Cartoned Unexpanded Group A Plastic Commodities. Multiple Row Rack Storage is NOT permitted. Maximum storage height Shall NOT exceed 35’ and Shall maintain a clear distance of at least 3’-0” between the top of storage and sprinkler deflector.

**Riser Details and Systems noted on Sheet FP-8**

1/FP8: 10” underground, 6” Check Valve and manifold to 6” risers for systems #06 and #07

2/FP8: 10” underground, 6” Check Valve and manifold to 6” risers for systems #03, #04 and #05

3/FP8: 10” underground, 6” Check Valve and manifold to 6” risers for systems #01 and #02

Thursday, March 6, 2025 DF: Review of 1st Resubmittal.

1) It is my understanding from conversation with Plans Reviewer Stephanie Murray that the Fire Pump for Buildings 4 and 5 along with a water storage tank (Sheets FP-9 and FP-10) will be removed from within this building and placed in a standalone Fire Pump Building. If this is indeed the case, you will need to remove any Sheets containing Fire Pump and Water Storage Tank information.

-------------------------

Thursday, March 6, 2025 DF: RTC: As discussed on the phone, the Fire Pump and Tank are still in the included in the submittal but a note on the Sheet stating For Reference Only has been added. The Fire Pump and Tank will be a separate submittal and permit.

3) The building has 3 separate risers (undergrounds) that then branch off at the manifold. Each riser is fed independently from the Fire Main that supplies the building. Based on this, these are considered three (3) completely - separate sprinkler systems that will each require their own Fire Sprinkler System Permit application.

Provide individual permit applications for each riser and ensure that the head count per system on the application is accurate.

-------------------------

Thursday, March 6, 2025 DF: RTC: We have now provided 3 fire sprinkler permit applications for the 3 fire pump lead ins as requested.

5) I am not able to find where the sprinkler design criteria have been provided [61G15-32.004]. Provide the 61G15-32.004 information (wet sealed and wet signed by a Fire Protection Engineer) or have the shop drawings wet sealed and wet signed by a Fire Protection Engineer.

-------------------------

Thursday, March 6, 2025 DF: RTC: The fire protection drawings are now wet sealed and wet signed by a fire protection engineer as requested.

7) I am not able to locate an air vent in each system [13:8.1.5].

Point out the location of the air vent(s) in each system. Provide the manufacturer’s specification sheets.

-------------------------

Thursday, March 6, 2025 DF: RTC: Air Vents are now provided on each system and noted on the shop drawings.

9) The underground for this building has not been submitted/reviewed. Until the underground has been submitted, reviewed and approved the Fire Sprinkler Plan cannot be approved.

-------------------------

Thursday, March 6, 2025 DF: RTC: Noted. (Underground approved on 02/24/2025)
