TO BE USED WITH FIRE FLOW CALCULATION INSTRUCTIONS
Fire Dept Use Only
1) Building Name: 14' AV' FMZ / /
PA - 1 L e
2) Address: 1 (0 5`l �, � . 1■ City /Co 1 f,,A D 1,4A
3) Type of Structure: (Check 1 Box) Date:
❑ I FR, II FR
❑ II One Hour, III One Hour
❑ IV Heavy Timber, V -One Hour
❑ II -N, III -N
C' V -N
4) Total Building Square Footage: 4' 920
Use the largest aggregate floor area of all floors inclusive of mezzanines as defined
by UBC Section 407 floor area. In Types I and II FR construction only, the three
largest successive floor areas shall be used.
5) Building Fire Flow (BFF): 7') 0 from UFC Table A- III -A -1.
(See handout on UFC)
6) a Single Occupancy Hazard:
1 C j t7 (BFF) X 1, 3 (Occupancy Factor) = Required Fire Flow (fill in line 8)
b Multiple Occupancy Hazard:
Occupancy
occ sq ft _ bldg sq ft = %BA f f
Occupancy
occ sq ft - bldg sq ft = . %BA
Occupancy
occ sq ft _ bldg sq ft = %BA
Occupancy
occ sq ft ± bldg sq ft = %BA
7) Occupancy X Factor:
% BA X gpm BFF X (occ fact) = FFfff
% BA X gpm BFF X (occ fact) = FF
% BA X gpm BFF X (occ fact) = FF
% BA X gpm BFF X (occ fact) = FF

8) Total Required Fire Flow: '2, 'Vi 5
9) Credited Required Fire Flow: (Use only one of lines a, b, or c)
a. Multiply Line 8 by 75% for full fire alarm or
b. Multiply Line 8 by 50% for automatic sprinkler protection
or
c. Multiply Line 8 by 25% for central station supervised automatic sprinkler
protection
10) Available Fire Flow': 9 (p 0 (P
f Round off numbers to nearest whole if Building Area ttt Fire Flow
Example: Apartment building with garages Type V -N construction, aggregate square
footage 12,000 square feet. Garages 3,500 square feet, apartments 8,500
square feet, BFF = 3,000 gpm.
Apartment 5,000 ± 12,000 = 71% of BA
Garages 3,500 - 12,000 = 29% of BA
71% (BA) X 3,000 gpm (BFF) X 1.0 (occ fac) = 2,130 gpm
29% (BA) X 3,000 gpm (BFF) X 1.1 (occ fac) = 959 gpm
Total Required Fire Flow 3087 gpm
The required fire flow of this standard is greater than 3,000 gpm, therefore, either area
separation walls (see Section 22 of Fire Prevention Ordinance) complying with UBC Section
505(0 would need to be installed or one of the automatic sprinkler alternates or central
station supervision alarm system as found in Section 25E (1), (2), and (3) of The Fire
Prevention Ordinance. One may also upgrade the type of construction to comply. The same
applications are true if required fire flow is greater than available fire flow.
•
1. If single occupancy hazard, place answer on Line 8. If multiple
occupancy hazard, skip to line 6b. When multiple occupancy hazards
are housed within a single fire flow area, the building fire flow
shall be factored out to the ratios of floor areas housing various
occupancies. Each portion of the building fire flow for a given
occupancy hazard shall be multiplied by the occupancy factor and
then added together to produce a required fire flow.
2. This information is available from the fire district unless the
building is in a newly developed area or new fire mains are to be
installed. If the latter is the case, please provide engineered
calculations showing estimated flows for the area.
