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

RESUBMITTING:
A. Make necessary changes and resubmit everything in person to the permit center. You may not make handwritten alterations on signed and sealed plan pages.
B. Once at the Permit Center swap out altered pages or insert new pages in EACH plan set (Job and Office). One copy of the removed/old pages from the JOB Copy will need to be submitted and marked "OLD". Do not forget to remove pages for work not associated to this permit. All plan papers must be the same size.
C. Provide a response to comments along with any supporting documentation. Response to comments is REQUIRED not optional.
- The response to comments sheet will need to include a response to each numbered comment and tell us where in the plans the comments was addressed. EX - "Top Left of Page E1-1" or "Page E1 Note 8".
- Code responses shall reference Florida Fire Prevention Code, 8th Ed.

 		 

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.

 		 

2) Based on the Comment above indicating the relocation of the fire pump from inside the building to an unknown location outside the building, the Hydraulic calculations will need to be verified by the Fire Protection Engineer that the Fire Pump relocation does not affect the calculation. Update the calculations if needed.

 		 

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.

 		 

4) A “Owner’s Certificate” has not been provided for this building’s Fire Sprinkler System [13:4.2].

Provide the Owners’ Certificate for review. Provide a copy to the Fire Protection Engineer for system design verification.

 		 

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.

 		 

6) I am not able to locate a recent hydrant flow test data in the sprinkler plans or in the documents provided. 13:4.6.1

Provide the hydrant flow test data conducted within the last 12 months.

 		 

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.

 		 

8) Plans indicated a fire pump inside the building. As noted above, the fire pump is being relocated to an exterior Fire Pump building. However, I noticed that the FDC consisted of a wall mounted 2.5” Siamese connection. St Johns County Fire Marshal’s Office requires that an FDC have a 5” STORZ connection with a 30° down angle be used for the FDC connection on all FDC’s 2.5” and larger.

When you are updating the system riser details on Sheet FP-8, also update the FDC connections and their locations.

 		 

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.
