FUS Calculations
PROJECT: 289 Island Hwy. CLIENT: Glentanna Date: August 21, 2020 File: 32668
Type of Construction: Mixed Coefficient (C) based on type of construction = 1.2 Total Floor Area: 4,886 m² Fire Flow From Formula ($F = 220 \cdot C \cdot A^{0.5}$): 18,453 L/min. (a) $\Rightarrow$ 18,000
Type of Occupancy: low Hazard: Hazard Allowance: <25%> (a) = <4,500> L/min. Sub-Total: 13,500 L/min. (b)
Automatic Sprinklers: Yes Sprinkler Allowance: 50% x (b) = 6,750 L/min. (c)
Exposures:
- North: 15 m (Separation) | 7 percent (Max. Charge)
- South: >45 m (Separation) | 0 percent (Max. Charge)
- East: 20 m (Separation) | 10 percent (Max. Charge)
- West: >20 m (Separation) | 10 percent (Max. Charge)
Exposure Allowance (75% Maximum): 27% x (b) = 3,645 L/min. (d)
TOTAL FIRE FLOW REQUIRED: (rounded) 10,395 L/min. (b-c+d) $\Rightarrow$ 10,000 TOTAL FIRE FLOW REQUIRED: 167 L/s
Construction Coefficient
- C=1.5, Wood Frame
- C=1.0, Ordinary (brick or other masonry walls, combustible floor and interior)
- C=0.8, Non-Combustible (unprotected metal structural components, masonry or metal walls)
- C=0.6, Fire-Resistive (fully protected frame, floors, roof)
- Floor Area includes all storeys, excluding basements at least 50% below grade
Hazard Allowance
- -25% dwellings, apartments
- -20% hospitals, elem. schools
- -15% high schools
- (*) Values to nearest L/minute
Separation and Maximum Charge
| (1) Separation | (2) Max. Charge |
|---|---|
| 0 to 3 m | 25% |
| 3.1 to 10 m | 20% |
| 10.1 to 20 m | 15% |
| 20.1 to 30 m | 10% |
| 30.1 to 45 m | 5% |
