Also the entire sprinkling thing is non-sense Lbear. There are so many ways to avoid sprinkling a building, its all in the code. Obviously things need to be done to avoid a sprinkler (such as in a school, the biggest thing is 1 hr rated corridors and 12,000 sqft building separations according to IBC)

Out here in AZ the code mandates that even residential homes above a certain square footage require sprinkler systems. When it comes to commercial properties, it's always mandatory to have sprinkler systems. I am not familiar with FL or codes out east.

Some areas are even more strict. Out in Anthem, AZ all residential homes (even single story under 2,000 sqft) are required to have a fire sprinkler system. It's the local code and it overrides IBC.

so if its required, how do they handle low flow pressures on main water supplies where a sprinkler system is not possible? Install fire pumps all over?

interesting. would you mind giving a cost per sq of construction for this? Not price per panel, but rather construction, if you know. Maybe you do not know the other trades. 80% of our projects are schools, always brick and block up here. Mostly around $150-160 sqft construction costs. We do a lot of smaller additions too so something like this may make sense, especially in zone 6.

Izerarc,
We did not do the turnkey project, the owner wanted SIPs and we supplied and installed for their GC:
6" walls (4 walls), 8" roof(roof taped with TPO powerbond and will be the finished roof), window and door openings ,interior steel stud framing, 14" x 12 ga. Marinoware Joists with versaroc T&G sheathing and 12" SIP walkway bridge,
the cost for our work was $34/ sq. ft.
much less than masonry and much faster, ultimately more energy efficient

That is a question I don't know the answer to. My current home has a fire sprinkler system installed in it by the builder as it was required by city code. According to the pressure gauge in my garage it shows 120 psi. The sprinkler line is tied into the same main water line coming into the home.

I know that any new commercial structure that houses people must be have a fire sprinkler system, no exceptions.

I just read an article in a magazine that is all about wood structures. They are building high rises in some areas using wood and the codes even get more stringent on fire sprinklers.

sounds like code writers are in bed with sprinkler companies. Does not make any sense to me. About half of our projects a sprinkler for a new school would pull the water pressure from the entire small town. This is part of the reason why IBC and code books make exceptions to sprinkler codes or allows more options with a sprinkler installed, especially when it comes to school design.
Oh well...

I typically estimate about $30/ sqft of 8" cmu block, liquid sprayed air barrier, 3" XPS insulation, 1" air space, and 4" brick for a go to school wall. EPDM roofing over 4" poly iso on metal deck is king around here as well, even though I am pushing TPO in our office.
I would be curious to see what sorts of time savings that would equate to cost savings could be had in a steel sips. Would have to add an exterior clad to that as well as some sort of high abuse interior finish. I have used a product called Genwall which is about the closest product to steel sips seen around here (even though its not sips at all...).
Change from stacked block or even precast is tough in my parts unfortunately.

A jockey pump is used ina areas with low pressure, 120 PSI is extremely high right off the municipal line,
residential waterline pressures in our area are 35 - 60 PSI

our project is an addition to an existing sprinklered building, therefore is has to be sprinklered as well
the "dried in" - "Box" was stood in just 3 days,
the GC - Tandem Construction in Sarasota was completely blown away by the speed,
this project will be clad with 7/8" thick wire lath and stucco
I will continue to update with photos

Except for high-rise buildings I've always seen fire hydrants more demanding of municipal water supply than sprinklers. Sprinkler demand is usually far less than hydrants. Sprinklers really are the best way to fight a fire if you have a combustible structure. Most people don't realize how fast a fire moves. More often than not the fire department is just there to douse the ashes and keep additional structures from catching fire. A sprinkler can actually save the structure.

Chris, I'm curious what you think of the Versaroc. It looks like it is over twice the weight of plywood per inch. Was it any more difficult to screw down?

Torben,
it is 150 lbs per sheet, it is fairly easy to screw, specs call for T& G to be glued
too pricey @ $110. /sheet plus $800.00 freight

12" SIP elevated walkway

12" SIP elevated walkway

Will they cover the walkway with any type of material or just leave it as the exposed metal SIP?

Power Bond taped SIP joint , to be permanent roof

Is the tape already installed?
Does the neoprene washer go on the underside of the larger washer or on the underside of the screw head?
Is there a specific torque setting on the screw heads? I assume it is being attached to a metal ridge beam of some sort.

after this photo was taken a 1/4" hardi-underlament was applied and it will be waterproofed by another sub-contractor

the neoprene is bonded to the aluminum washer

no torque setting, just drive in sufficiently to dimple metal skin , that will firmly set the rubber to the skin

it is a mono sloped roof with attachment at the high and low walls

ready for stucco

Chris,What kind of fastener do you use for the lathe? Is this 6" on center?

Torben,
use a #8 wafer head screw (sharp point) aka lath screw 12" oc & 6" oc at overlap

I love these SIP projects. Keep them coming Chris. I'm mainly commenting so this gets saved in my threads. It's really amazing though how sleek it all looks.
