convergence occurs is calculated as a horizontal element of egress using

0.15”/person or 0.2”/person.

a. Please confirm that the stair landing at level 1 discharge should

be sized (in length) at 0.15” per person.

6. At Level 1, stair discharges of Stair 6 and Stair 3 need to be ‘readily visible

and identifiable from point of termination to enclosure’.

a. Please confirm that the stair discharges on Level 1 comply with

“readily visible and identifiable from point of termination to

enclosure” for application of SBC 1023.

7. Assembly uses, as defined by Table 1004.2.1, are to be calculated as “net”

rather than gross.

a. It is our understanding based on net versus gross definitions that

circulation areas are not loaded when stories are primarily

assembly use.

b. Pre-function areas are considered non-simultaneous use to the

main assembly area they serve. In our exiting calculations we have

determined the max occupancy of ‘both’ spaces in a simultaneous

use situation, and have selected the higher occupancy space as




that which contributes to exiting requirements. Please confirm this

is See Sheet G212, Level 3 for an example of this condition and

calculation.

Seattle Requirements for High-Rise Secondary Water Supply

Water Tank: An automatic secondary on-site water supply storage tank shall be provided for

high-rise buildings in accordance with SFC Sec. 903.3.5.2, and meet the requirements of

NFPA 22 and the following:

OPTION 1 Single Fire Pump with Storage Tank Having Automatic Refill Features

Tank Refill Lines:

Dual automatic refill lines, each capable of refilling the tank at a minimum rate of 150 percent

of the fire pump(s) capacity, shall be installed. Ref: NFPA 20 - 4.31.3.1.1




A manual tank fill bypass designed for and capable of refilling the tank at a minimum rate of

150 percent of the fire pump(s) capacity shall be provided. Ref: NFPA 20 - 4.31.3.1.3

Tank Fill Valves and Control Systems: The two automatic refill lines shall have separate

automatic tank fill valves that are listed for fire service and arranged for automatic operation.

Each automatic tank fill valve shall be provided with a separate approved means of actuation

such as float assemblies, pressure sensors, etc. that are supervised by the fire alarm

system. The status of the valves (i.e., ‘open’, ‘closed’) shall be indicated at the valves and in

the Fire Command Center (FCC).

The tank shall be kept filled, and the water level shall never be more than 4 inches below the

designated fire service level. Ref: NFPA 22 - 14.4.3

Tank Level Indicators: Two tank level indicators are required, one located in the FCC and

another in the immediate vicinity of the tank fill valves. The tank level indicator monitoring

shall be provided through the fire alarm system in accordance with NFPA 72.

Two separate and distinct signals shall be initiated: one indicating that the required water

level has been lowered or raised (off-normal), and the other indicating restoration. Ref: NFPA

72 - 17.16.3.1

The off-normal signal shall be initiated when the water level falls three inches or rises three

inches. Ref: NFPA 72 - 17.16.3.2.1

Tank Low Level Alarm: Separate and distinct tank low level audible and visible alarms shall

be provided in the FCC and in the vicinity of the tank fill valves, and activate when the tank

water level drops below 50% capacity. The tank low level monitoring shall be provided

through the fire alarm system in accordance with NFPA 72. The signaling devices shall be

clearly labeled “Water Tank Low Level Alarm” or equivalent. An independent silence switch

shall be provided for the tank low level alarms in the immediate vicinity of the alarm devices.

Tank Overflow Protection: An approved means to prevent the tank from overflowing into the

building shall be provided. Where an automatic shutoff valve is provided, it shall be listed for

fire service and have dual (redundant) means of actuation such as two float assemblies,

pressure sensors, etc. that are supervised by the fire alarm system. The valve shall be

supervised by the fire alarm system and status (i.e., ‘open’, ‘closed’) indicated at the valve

and in the FCC.

Pump By-pass: A full size by-pass shall be installed around the storage tank and the fire

pump in accordance with NFPA 20. The by-pass shall be installed on the supply side of the




tank fill valves and connected to the system on the downstream side of the fire pump and any

sprinkler system pressure regulating valves installed on feed mains.

OPTION 2: Two Fire Pumps and Storage Tank Without Automatic Refill Features

The primary fire pump shall be supplied by a dedicated fire service main and the secondary fire pump supplied from the storage tank. The pumps shall operate at the same rated flow capacity and at similar discharge pressures. When using Option 2, automatic refill of the tank is not required. The means to fill the tank shall be sized to fill the tank in a maximum time of 8 hours. Ref: NFPA 22 – 14.4.2 The tank shall be kept filled, and the water level shall never be more than 4 inches below the

designated fire service level. Ref: NFPA 22 - 14.4.3

Tank Level Indicator: A tank level indicator is required in the immediate vicinity of the tank

fill valve.

Pump By-pass: A full size by-pass shall be installed around the primary fire pump in

accordance with NFPA 20. The by-pass shall be connected to the system on the

downstream side of any sprinkler system pressure regulating valves installed on feed mains.

Seattle Requirements for High-Rise Generator Fuel Tanks

Ensure that the as a minimum the following information is provided on the on the architectural plan submittals:

1. Provide detail on plans indicating type of tank (i.e., UL-142, UL-2085, or other type of tank), type of fuel, and how much will be stored on-site.

2. Provide detail on plan (plan and elevation views) showing the location of the diesel fill

connection, located on the exterior of the building, at least 5 feet from building openings and property lines in accordance with SFC Section 5704.2.7.5.2.




3. Provide details on plans indicating location (plan and elevation views) and routing of normal vent for diesel tank (manifolding of normal vents is not allowed) in accordance with SFC Section 5704.2.7.3.3.

4. Provide details on plans indicating location and routing of emergency vents diesel

tanks (manifolding of emergency vents is not allowed) in accordance with SFC Section 5704.2.7.4.

Seattle Requirements for Protection of Wiring Required by Section 909.11

1. Power and control wiring that serves the pressurization and other smoke control equipment, regardless of voltage, shall have fire-resistance-rated protection (rated cable, installation in shafts, embedment, etc.) of at least two hours. Exception: Fire-resistance rating is not required for wiring serving a generator in an unprotected area in a garage that is separated from the rest of the building by 2 hour-rated construction.

2. Where wiring protection is provided by installing in a rated shaft, protection of wiring is

required between the fire command center and the shaft.




3. Protection of wiring is not required for rooftop or penthouse wiring where installed outside the building envelope or in a penthouse that is not required to be protected.

4. Protection is not required for HVAC fans used to exhaust intermittent floors.

5. Protection is not required for the dampers on the HVAC equipment unless dedicated

for shaft pressurization.

6. Wiring required to have 2-hour protection can be in a shaft with other wiring. The "independent route" requirement in Section 909.11 means separate raceway from normal power.

Seattle High-Rise Requirements for a Roof Hatch When Approved as a Penthouse Alternate
