GENERAL INFORMATION:
The plans for the above-mentioned project have been reviewed. The following comments address areas of concern, non-compliance with the governing code, potential errors, or omissions
in the proposed design. The appropriate design professional must address each comment below and submit a written response in addition to revised plans and calculations if necessary.
Please cloud any revisions made to the construction drawings and provide the date of the latest revision on each revised sheet.FIRE COMMENTS:Hydraulic Nodes: Please indicate the hydraulic
nodes on the system riser diagrams for all applicable system nodes.Water Flow Test Data: It appears no reductions in the flow data have been provided to account for seasonal or daily
fluctuations as a result of increased demands or changes in the operation of the water system. Fire sprinkler designer to verify that such fluctuations have been accounted for.Hydraulic
Calculations: Several of the calculations indicate the most demanding heads are either at minimum PSI or minimum GPM (Node 107; Node 302; Node 500; Node 600; Node 807). Node 915 appears
to be below the minimums for both PSI and GPM. Please verify the system calculations and ensure that fluctuations have been accounted for as indicated in comment F2.Standpipe: Please
state on the plans which classification of standpipe is being provided (class I, II, III).CPVC Seismic Bracing: Seismic bracing shall be provided on all feed and cross mains regardless
of size as required by NFPA 13 section 9.3.5.5.1 and on all branch line pipe 2 ½ inches and larger per NFPA 13 section 9.3.5.6. Please revise the plans to indicate the required bracing.Trash
Chute: Clarify if the building has a trash chute and if the fire suppression system will protect the trash chute. Provide a detail for the trash chute (termination room to roof detail
showing chute and fire sprinkler locations). Sheet FP3 appears to indicate a trash chute.Dry System H2O Time: The dry pipe system size must be designed such that initial water is discharged
from the system test connection in not more than 60 seconds, starting at the normal air pressure on the system and at the time of fully opened inspection test connection. Place a note
on the plans indicating the required water delivery time as outlined by NFPA 13 section 7.2.3.6.1. [2013 NFPA 7.2.3.2; 7.2.3.6.1]Dry System Valve Room: Please confirm the following
requirements are being met for the valve room of the dry pipe system as required in 2013 NFPA 13 7.2.5.2:The valve room must be lighted and heated.The source of heat must be of a permanently
installed type.Heat tape cannot be used in lieu of heated valve enclosures to protect the dry pipe valve and supply pipe against freezing.The supply for the fire sprinklers protecting
the Valve Room Enclosure, must be connected on the dry side of the system.
General Information Sign: Fire sprinkler contractor to provide a general information sign as required by section 25.6 of NFPA 13 for each fire sprinkler riser to indicate the system
design basis and information relevant to the inspection, testing, and maintenance requirements required by NFPA 25. [NFPA-13:25.6]

Corrections and comments made during the review process do not relieve the permit applicant or the designers from compliance with code requirements, conditions of approval, and permit
requirements; nor are the designers relieved of responsibility for a complete design in accordance with the laws of the state of Washington. This review is for general compliance with
the International Building Code as it relates to the project.
