Another Question re: USFS Fire Suppression System

[Alias]

Okay, here we go.

Sprinkler system has been added for the new USFS 24,684 sq. ft. building in lieu of other fire protection provisions.

Current approved plans contain drawings for a fire alarm system. I want to be ready if the project manager wants to delete something so my questions are:

1) With the addition of sprinklers, is the alarm system required (strobes, riser, etc.) or are sprinklers sufficient?

2) Is only a riser acceptable with sprinklers?

3) Can the fire alarm system be removed with the installation of sprinklers?

And finally, how do you calculate fees?

TIA,

Sue

Alarms and notification are two different things

Alarms are covered under 903.4

Notification for a Group B is 907.2.2

what code and edition is this reviewed under??? any admendments to the code??

 

[cda]

if nothing in place, base it on cost of the job materials and labor, then use whatever you have in place to fiqure a cost of a permit for a building.

Do not have access to CFC

But minimum IFC is a monitoring system

903.4 Sprinkler system monitoring and alarms.

All valves controlling the water supply for automatic sprinkler systems, pumps, tanks, water levels and temperatures, critical air pressures, and water-flow switches on all sprinkler systems shall be electrically supervised.

And Nfpa will require one outside device

What occupancy type is this??? That will drive whether a full blown system is required

Fantastic, mr. Wonderful has revealed himself!!!! Please keep on replying

 

[FM William Burns]

I’m with MT on this one whereas alarms are only required if applicable in accordance with 907.2.2



OMG….it’s great to see OFG is Poobah………..I have missed his wisdom!

Also did no think in this thing, your code may not require a full blown system, but the Feds may want one!!!!!

Mixed Use B/A-3. Owner/builder switched horses in mid-stream and decided to use fire suppression system with sprinklers instead of using the 2-hour fire resistance system on approved plans.

Now need to go back to the books

What is the A-3, and occupant load

 

[Alias]

cda -

A-3: Assembly uses intended for worship, recreation or amusement and other assembly uses not classified elsewhere in Group A including, but not limited to: .................. So, this is an 'other' at 110 occupancy.

B would be for the portion that will be the USDA offices.

I am fairly sure of this as there will be a dispatch office located within the building.

Sue

 

[cda]

Sorry to ask the question again

What will they be doing in the A-3. Training room, meeting, what is the other??

Not the dispatch room is it??

 

[Alias]

Sorry to ask the question againWhat will they be doing in the A-3. Training room, meeting, what is the other??

Not the dispatch room is it??

Due to the size (over 50 occupants) it will include the entire operations for the Forest Service unit located here - admin, dispatch, info desk, offices, conference room, break room, ad nauseum. The B portion is a similar set-up (less than 50 occupants) for USDA & RDA.

Sue

 

[cda]

Are you mixing B and A together and calling it A??

Or is it B with some " A" accessory use?

 

[Alias]

Mixed Use Building A occupancy - USFS offices - over 50 occupants

B occupancy - USDA offices - under 50 occupants

2 different agencies under the same roof with a wall between agencies.

Sue

 

[cda]

I am in the state of confusion

If an office has 1000 people in the same room, size Appropriate , it is still a "B".

 

[mtlogcabin]

Over 50 occupants in a single office setting is still a "B" occupancy use not an "A".

Think of a call center or news room where you have a bunch of little cubicles the employees work in. That is a "B" use even if you had 300 people working in the one room

 

[Alias]

Well, then their designer and the plan checker are wrong. Just another wrinkle in this convoluted project. Thanks.......
