10) FP pages show sprinkler system information but does not outline all design criteria. An ENGINEERED sealed Design Criteria for a fire sprinkler system exceeding 49 heads is required to be submitted with the general construction documents. We are unable to approve the plan until this information is provided. (FAC 61G15-32.002(5)) (The signed and sealed design criteria is the general guidelines with design and scope of the sprinkler system. It is not a full set of shop drawing.) THIS IS WHAT IS REQUIRED BY FLORIDA ADMINISTRATIVE CODE 61G15-32.004, (A-M) as of June 19th, 2015, Design of Water Based Fire Protection Systems.
Wednesday, July 25, 2018 Response to comments indicates "Sheet FP3 has been updated to include all design criteria according to Florida Administrative Code Chapter 61G15-32. The owner's certificate is included in this resubmission. The shop drawings will be submitted by the sprinkler contractor."
Upon review of the sprinkler design criteria the following needs to be clarified or addressed in accord with the requirements of FAC61g15-32:
- Page FP3 box 61g15-32.003(4) indicates that the fire protection contractor will need to get their engineer to sign and seal the shop drawings. Per FAC 61G15-32.002(5)(6) after the Fire protection system engineering documents (Criteria) is submitted with the building plans, the shop drawings, when submitted, require no additional engineering input or seal.
Please either: 1) Remove this comment or 2)clarify the comment preparing the fire sprinkler contractor to provide: a) Have ___new engineer____ submit a registered letter to ___EOR____ notifying to reuse the already sealed contract documents therefore assuming all legal responsibility for the system in accordance with FAC 61G15-27.001. or 3) Have the owner or project engineer submit a letter to our office completely removing ___EOR____ as engineer of record for the project. or 4) Have the engineer of record provide a note on the shop plans they approve for design requirements and performance only.
- c) On page FP3 box 61g15-32.004(2)(c) directs me to box 61g15-32.003(3) which tells me everything will be light hazard unless otherwise noted. Below light hazard, ordinary hazard group 2 is listed but I am not sure where this will be? Please list hazard location for each room or area.
- e) unable to locate water supply characteristics such as main size and location, dead end or circulating, distance to nearest circulating main, minimum duration and reliability for the most hydraulically demanding design area. If I am over looking please point out.
- f) flow test provided is over a year old (4 6 17). Base off flow test less than 1 year old.
- g) unable to locate if backflow is electrically monitored. Looks like the response from architect under item #4 above will require the backflow to also be monitored. Please address.
- h) Regarding MIC, the comment currently reads our Office monitors the water supply. We do not monitor the water supply therefore can not comment MIC. I have seen severe pipe corrosion in more than one location. Those building owners have choose to repair system only and not have water tested. Other sprinkler engineers have addressed MIC in their submittals. It is the responsibility of the Engineer to evaluate the water supply and make a determination of the corrective action if needed. Please clarify if the system will need corrective measures then identify what correction will be taken.
- m) owners certificate provided on 8x11 but not signed/sealed by EOR. Either show owners certificate on signed/sealed FP pages or have EOR sign/seal 8x11.
Wednesday, January 16, 2019 Response to comments indicates "On sheet FP3, 61g15-32.003(4) - The engineer of record shall provide a note on the shop plans that they approve for design requirements and performance.
c) The hazard classification types are listed on sheet FP3, 61g15-32.003(3) and the areas listed are on sheet FP0, Fire Protection General Notes #6.
e) See sheet FP1 for fire main size entering the building and the longest/ most demanding inside the building. See sheet FP0 for Preliminary Sprinkler Calculations. Distance from fire riser to most remote/demanding is given there. See civil site utility plans for fire main outside of the building.
f) See sheet FP0 Preliminary Sprinkler Calculations for updated flow test dated 8-30-2018.
g) Backflow preventer is existing. See sheet FP0, Fire Protection General Notes #20 and #21.
h) Owner to test the water for MIC.
m) See sheet FP4 for Owner's Certificate.
Upon re review the following remain unaddressed:
c) hazard class for parts , night drop and receiving were classified as OHG1. NFPA 13:5.3.2 classifies these as OHG2.
f) what is the hydrant butt coefficient and location of test in relation to the hydraulic point of service?
h) The state of Florida requires the Engineer to identify if MIC is an issue or not. If it is, it is the EOR's responsibility to call out the corrective measures.
