Fire Sprinkler System Plan Review.
I have reviewed the plans to 1999 Edition of NFPA 13 and make these written comments. Additional
notations are provided on the plans if required.
The adequacy and dependability of the water source are of primary importance and shall be fully
determined, with due allowance for its reliability in the future. Plans were reviewed with current water
information provided.
This fire sprinkler system was designed, showing that there would be 64.15#static pressure at the base of
the riser. If this design pressure is not available you may need to provide a fire pump, or redesign the
system.
Due to the limited supply in water pressure, changes in the field will be held to the minimum and shall be
approved by the Authority Having Jurisdiction (AHJ) before changes are made.
GENERAL NOTES:
1. BRACING: Bracing shall be provided at the top of each riser.
2. CONTRACTOR CERTIFICATION: All underground pipes serving the fire protection system, including fire
hydrants shall be installed by a Washington State Fire Marshal licensed contractor with a "U" designation.
Contractor stamped underground testing documents shall be provided to the local AHJ before providing
water to the sprinkler system.

Attention: Ray Mow
Project Name: Hood Canal Elementary School
Project#: 205-048
Dear Ray:
The fire protection sprinkler system shop drawings (dated July 28'h, 2006), hydraulic calculations (dated
July 27th, 2006), seismic bracing calculations, and equipment submittals for the above named project have
been reviewed. Please have the sprinkler contractor re-submit additional manufacturer's literature,
hydraulic calculation #4A, hydraulic calculation #5, a certified pump curve, and revised drawings for
approval. The latest edition of N.F.P.A. #13 adopted by the State of Washington is the 1999 and is the
edition utilized by the fire protection sprinkler system contractor in the design. The 1999 edition of N.F.P.A.
#13, project specifications, and the contract documents will be used as the basis of this review.
Equipment Submittal Comments:
1. Per Specification Section 15340 Paragraph 1.01.A.2 and Sheet 1 of 23 of the submittal
drawings, the start point is 5'-0" outside of the building's footing. Pipe submittals for the
piping to be installed in the underground have not been provided, unless the In-Building
Riser(submitted on)extends 5'-0"outside of the building's footing.
2_ Per Specification Section 15335 Paragraph 2.13.A, the air compressor is required to have
a 10 gallon minimum air tank. The equipment submittals do not indicate that the tank
model air compressor is being utilized and could be the tankless package also indicated
on the line item. The fire protection sprinkler system contractor shall provide the tank
mounted style indicated on the line item identified.
3. Per Sheet M6.01 and M6.05 of the Contract Documents, a 10" 24 Volts D.C. electric bell
is required for the Main School Building and a 10" 110 Volts A.C. bell is required for the
Fire Pump House. The equipment submittals only indicate a 10" 120 Volts A.C. electric
bell. The fire protection sprinkler system contractor shall provide both bells indicated in
the contract documents.
4. The equipment submittals for the Access Doors do not meet project specifications.
Specification Section 15330 Paragraph 2.18 and Specification Section 15335 Paragraph
2.21 require the Access Door to be constructed of 14 gauge materials not the 16 gauge
material indicated in the submittal. The Access Doors are also required to be key
operated cylinder lock style and not a sliding bolt with a ring style. This criteria is also
Plan Review Page 1
t
indicated on Sheet 8 of 23 of the submittal drawings. The manufacturer submitted
"Elmdor' is not a manufacturer listed on the prior approved list of manufacturers and a
"Request For Substitution" form was not generated prior to the bid date as required in
Specification Section 15055 Paragraph 1.05 and Specification Section 15335 Paragraph
1.13.C.
5. Per Specification Section 15335 Paragraph 1.13.D.11 and Sheet M6.01 of the contract
documents, an air maintenance device is required to be submitted and has not been
included in the submittal package.
6. Per Specification Section 15335 Paragraph 1.13.D.16 and Sheet M6.01 of the contract
documents, air pressure gauges are required to be submitted and have not been included
in the submittal package.
7. Per Sheet M6.05 of the contract documents and Sheet 3 of 23 of the submitted drawings,
flanged fittings are required as part of the fire pump installation and have not included in
the submittal package.
8. Per Sheet M6.05 of the contract documents and Sheet 3 of 23 of the submittal package,
the pressure maintenance pump shall be rated for a maximum horse power rating of 1
H.P. The equipment submittal indicates that the pressure maintenance pump is rated for
1'/z H.P. The electrical service does not support this large of a motor and will be the
responsibility of the fire protection sprinkler system contractor to pay for the fees
associated with upsizing the electrical service. Also the rating of the jockey pump
indicated in the equipment submittals is 201 feet of head (78.1 p.s.i.) @ 15.85 g.p.m. with
a shutoff pressure of 280 feet of head (121.3 p.s.i.). The contract documents indicate that
the shutoff pressure is to be in the area of 80.7 p.s.i. and per N.F.P.A. #20, the pressure
maintenance pump is to be sized so that the flow from the smallest single sprinkler head
installed cannot be maintained by the pressure maintenance pump. It appears that this
pressure maintenance pump is oversized and a smaller pump shall be selected by the fire
protection sprinkler system contractor that meets the project requirements.
9. The certified pump curve for the selected diesel driven fire pump is not included in the
submittal package and shall be included.
10. Per Specification Section 15345 Paragraph 1.08.D.17 and 1.08.D.18, equipment
submittals are required for the exhaust pipe insulation to be installed and have not been
provided in this submittal package.
11. Per Specification Section 15345 Paragraph 1.08.D.19 equipment submittals are required
for the wall thimble to be installed and have not been included in this submittal package.
12. Per Specification Section 15345 Paragraph 1.08.D.19 equipment submittals are required
for the hose valves to be installed to test the fire pump and have not been included in this
submittal package. These valves are shown on Sheet M6.05 of the contract documents
and Sheet 3 of 23 of the submitted drawings.
Drawing Comments:
13. Sheet 1 of 23: The site plan indicates that a 4" swing check valve is to be installed in a
vault for the yard installed fire department connection_ The check valve is shown as part
of the riser piping in the riser detail shown on Sheet M6.01 of the contract documents and
Sheet 2 of 23 of the submittal drawings. The check valve shown in the underground is a
duplicate and should be removed.
14. Sheet 2 of 23: Specification Section 15335 Paragraph 1.12.A requires a table to be
created adjacent to the riser detail that indicates the pipe size, pipe type, pipe diameter,
Plan Review Page 2
L�
the associated lineal length for each pipe size, and the sum of volume of air contained
within the dry system piping to verify the air compressor sizing. The submitted drawings
just indicate the overall capacity of 130 gallons and cannot be verified.
15. Sheet 2 of 23: The elevation view and plan view of the riser detail do not match and shall
be revised. The elevation view indicates that the fire department connection piping goes
straight down through the finished floor and the plan view shows the piping penetrating
the finished floor near the exterior wall. A note indicated on the elevation view indicates
that the plan view indicates the correct routing. The elevation view should show the
elbows and offsetting indicated in the plan view with the penetration closer to the exterior
wall, but not at the same location as the supply flange (for clarity).
16. Sheet 2 of 23: The piping indicated in the riser details do not have the associated lengths
indicated for each piece of pipe. The details are not complete and cannot be used for
fabrication, installation, or verifying the hydraulic calculations.
17. Sheet 2 of 23: Sheets 9 to 23 of 23 indicate that 1,065 sprinkler heads are required on
this project. The riser equipment list on Sheet 2 of 23 indicates that a single twelve head
spare head cabinet is to be provided. N.F.P.A. #13 requires a stock of 24 sprinkler heads
when more than 1,000 sprinklers are installed on a project. The fire protection sprinkler
system contractor shall provide an additional spare head cabinet.
18. Sheet 3 of 23: The Fire Pump Criteria indicated in the middle of the drawing cannot be
verified without the certified pump curve being part of the equipment submittals.
19. Sheet 3 of 23: The Fire Pump Set Points cannot be verified without the certified fire pump
curve and the submittal information for the jockey pump does not match the values
stated.
20. Sheet 3 of 23: Sheet M6.05 of the contract documents indicate that a wet pipe automatic
fire protection sprinkler system is required to protect the fire pump house. The pump
house drawings submitted by the fire protection sprinkler system contractor does not
indicate that a sprinkler system is to be installed to protect the fire um house.
pump
Construction note#6 also references the inspector's test discharge and sprinkler system
main drain discharge. The fire protection sprinkler system contractor shall provide the
sprinkler system required.
21. Sheet 3 of 23: There are two 4-way seismic braces indicated in the elevation view of the
fire pump house and the equipment list only indicates one.
22. Sheet 3 of 23: Equipment list #31 points to a drain line that is shown on Sheet M6.05 of
the contract documents. The drain line has been removed on the submittal drawings and
equipment list#31 points to nothing.
23. Sheet 3 of 23: The piping indicated in the fire pump house details do not have the
associated lengths indicated for each piece of pipe. The details are not complete and
cannot be used for fabrication, installation, or verifying the hydraulic calculations.
24. Sheet 3 of 23: Equipment list#55 indicates one spare head cabinet is to be provided and
it is not shown on the fire pump details.
25. Sheet 4 of 23: The fuel tank equipment list item #9 is indicated as a quantity of 0, but the
item is part of the diesel tank detail. Sheet M6.06 of the contract documents also
indicated this incorrectly.
26. Sheet 9 of 23: It appears that the extended coverage sprinkler heads are spaced for a
18X18 head spacing. The sprinkler head shown in Clothing #124 is placed for a 20X20
head spacing. This room also has surface mounted light fixtures and the extended
Plan Review Page 3
coverage semi-recessed sprinkler head appears to be placed less than 12" from the light
fixture and does not meet N.F.P.A. #13 obstruction requirements.
27. Sheet 10 of 23: Kitchen #217 contains a cooking hood between Gridline "A14" and "A15"
at gridline "B13". It appears that two semi-recessed sprinkler heads are shown in the
same location as the cooking hood. The fire protection sprinkler system contractor shall
verify that these heads can be installed where they are shown.
28. Sheet 15 of 32: Special Education Toilet#238 has surface mounted light fixtures and the
extended coverage semi-recessed sprinkler head appears to be placed less than 18"
from the light fixture and does not meet N.F.P.A. #13 obstruction requirements.
29. Sheet 17 of 23: Between Gridline "A17" and "A18" and Gridlines "616" and "1317" there
are several ducts being placed against each other creating a plenum box prior to
penetrating the exterior wall. The ductwork is over 48" in width and requires sprinkler
protection beneath.
30. Sheet 20 of 23: All the pendent sprinkler heads shown Special Education Classroom #23
on Sheet 13 of 23 are not shown on this drawing.
31. Sheet 21 of 23: Provide an inspector's test valve for the wet system or indicate where the
inspector's test valve is located on the drawings.
32. Sheet 22 of 23: At Gridline "AF and "B9" there are several ducts that enter a plenum box
prior to penetrating the exterior wall. The ductwork is over 48" in width and requires
sprinkler protection beneath.
33. Sheet 23 of 23: Provide an auxiliary drain valve for the piping installed under the platform.
34. Sheets 16 to 23 of 23: Many of the drops to pendent sprinklers are from branch lines
installed at the roof level with upright sprinkler heads. The upright sprinkler heads are
required to be installed parallel to the roof level and does not allow pendent sprinkler
heads to be installed plumb, unless the outlets are welded at an angles that compensates
for the roof slope or additional elbows are added. The fire protection sprinkler system
contractor shall install all pendent sprinkler heads true and plumb.
35. Sheets 16 to 23 of 23: Many of the branch lines are indicated as being installed near the
roof with very long drops to pendent sprinkler heads. These long drops shall be verified
during a site inspection for excessive movement per Specification Section 15330
Paragraph 3.01.F and shall be restrained accordingly.
36. Sheets 16 to 23 of 23: The requirements of N.F.P.A. #13 (obstructions) shall be verified
for all semi-recessed pendent sprinkler head locations (extended coverage or standard
spray) shown on the drawings near surface mounted lights in areas consisting of gypsum
wallboard ceilings.
37. Sheets 16 to 23 of 23: Per the manufacturer's literature, dry sidewall sprinklers can onl�r
be installed into threaded tee fittings and are not approved for installation into 90
threaded elbow fittings and threaded couplings. Revise drawings to show threaded tees
with plugged outlet for installation of dry sidewalls.
Seismic Bracing Comments:
Plan Review Page 4
38. All Brace Calculations: The calculation indicates that the attachment is to a stud wall per
the details shown on Sheet 7 of 23 of the submittal drawings. A '/2' X 4" long lag bolt is
indicated as being the fastener for this brace. The point of connection shall not be into a
2X4 or into the side of other 2X framing members in which the lag bolt protrudes through
the wood on the backside. If the lag bolt protrudes through the wood members they shall
be removed and replaced with through bolts with nut and washers and re-evaluated for
conformance with project specifications and N.F.P.A. #13 load restrictions.
Hydraulic Calculations Comments:
39. All Calculations: The certified pump curve is required to verify the pump cure utilized in
the hydraulic calculations.
40. All Calculations: The pipe segment from the "Base of Riser' to the "Underground2"
indicates a pipe diameter of 6.16 and a C-factor of 100. These numbers appear to be
smaller than expected and adds an additional safety factor and is acceptable.
41. Hydraulic Calculation#4: The sprinkler heads on partial branch lines shall be the sprinkler
heads closest to the cross main. This creates a more demanding situation and is shown
in N.F.P.A. #13 this way. Sheet 19 of 23 of the submittal drawings indicate the sprinkler
head at the end of the branch line was calculated. There is a large enough margin left in
the calculations that the hydraulic calculations are acceptable.
42. Hydraulic Calculation #4A: The sprinkler heads on partial branch lines shall be the
sprinkler heads closest to the cross main. This creates a more demanding situation and
is shown in N.F.P.A. #13 this way. Sheet 19 of 23 of the submittal drawings indicate the
sprinkler head at the end of the branch line was calculated.
43. Hydraulic Calculation #4A: The remote area contains 7 extended coverage sprinklers
heads and the hydraulic calculations only included 6 sprinkler heads. The pendent
sprinkler head adjacent to upright#407 appears to have been omitted.
44. Hydraulic Calculation#5: The remote area indicated on the drawings contains 5 sprinkler
heads in the corridor. This corridor is not rated and does not contain self closing doors.
N.F.P.A. #13 considers this corridor unprotected and requires 7 sprinkler heads to be
contained within the remote area.
When these issues have been resolved and the information that has been requested is gathered, have the
sprinkler contractor re-submit additional manufacturer's literature, hydraulic calculation #4A, hydraulic
calculation #5, a certified pump curve, and revised drawings for approval. Any portion of the sprinkler
system that is to be installed exposed shall be addressed in writing with sketches (prior to the piping being
Y e Po 9 (P P P 9 9
fabricated or installed) to the Architect and Engineer to evaluate. Please feel free to call if you wish to
discuss any of these issues in more depth. Thank you for your time.
