UFGS spec section 21 13 00.00 40 vs 21 13 13

Am I right in thinking that one should edit 21 13 00.00 40 for the piping leading into the fire riser room and delete the references to the sprinkler system (and any other unused interior piping) and specify the sprinkler system from the riser into the occupied space(s) using 21 13 13? David

Material cost - best practice for a Corps of Engineer Project

Having sprinkler contractors reprice an Air Force housing project we are working on. The RFP is a steel only job (tried to get approval for CPVC but no go). What are you seeing for materials that provide some cost control… Sch 7, galv thin wall, ?? David Toshio Williams, PE*, FPE – Lead MEP/FP

FA not sprinkler question

I’ve been asked to look at a new industrial building, generally unoccupied except for servicing, that has a fire and gas detection system and audible and visual notification devices. At this point I’m not sure this facility actually requires a FA system, as it might just be an owner requirement

RE: Fire Pumps and fire apparatus

We do a fair amount of design at an Air National Guard base that has a HP fire line to service various hangers and the associated AFFF systems. This system was installed before my time, but it does have a few hydrants on the system, I think mainly for flow testing as the system expands. I will

fire protection of Transformer yard "under" parking ramp

We have a transformer yard at grade that is located under an multistory open parking structure. We caught it in time to have FR3 oil supplied in the non-FM utility company transformers and we believe we have the proper separation distances according to FM 5-4. We have 5 feet from non-combustible

Re: Hollow Core Concrete Seismic Braces

Many times there is a topping slab that can cover a through bolt and backing plate, or the precaster “could” install embedments. Takes lots of coordination! I like to spec embedments in parking ramp decks for the mains as it is such a corrosive environment and I can’t count on SS drill in anchor

Location of hydrant valves in CA.

A civil engineer friend of mine is working on a state project in California and there is a fight between the water purveyor and the state fire marshal as to the location of the hydrant valves. The water purveyor wants the valves to be right off the main and does not feel a need to keep the valve

Metal Mesh Ceiling tile replacement

We have a community college client that wants to replace standard ACT with a perforated metal mesh tile that is 60% open. My assumption is that change would require installation of heads above the ceiling in the area of the metal mesh, perhaps putting a bulkhead around the area with the mesh pan

Hey Scott and other cold weather practitioners in Fire Protection. Any feed back on the “new” Tyco LFP antifreeze. Looks like it may have some use in southern MN locations, but with Duluth at annual 99% extreme of -24.9 and 50 year extreme at -36.6 maybe not such a good idea yet. We plan on stic

Re: STANDPIPES NFPA 14

That’s funny as I have in design right now an exterior standpipe that has a wrap-around stairway so that the landings are separated both horizontally and vertically by a substantial amount as the stair wraps around the end of the building. So both types of standpipes in one! Due to the facility

Re: 13R and Well Pump?
