Thing about is you can't always point the finger at the EOR.  As a
contractor I did a some of our own design work and saw things installed
by MY company that didn't match MY drawings.  Fortunately I could roll
some heads over the screw up and get it fixed, unfortunately the fix
cost ME money, but at least I knew it had been put in right.  Some guys
just don't read and some think their little change isn't significant.  

So moral of the story is that even if their was an EOR, you can't lay
the error completely on him.  For the most part the fire protection
engineers and designers rarely get permission by their employers to
visit job sites once their drawing has left their office. (bigger AE
firms are less likely to grant someone like fire prot a plane ticket to
visit the job site) So they have no input on the installation.
Acceptance of installations are often left to the discretion of some
General Contractor's field superintendent or the local inspector.

Subject: RE: Do you look up?

When I "look up" at work that is incorrect, I always wonder if there was
an engineer of record involved on the project. Then I wonder how much
money they were paid to be the "engineer of record."  Then I wonder how
much time they actually spent on their "performance spec" that included
no performance criteria outside of references to code.

Obviously, mine is a cynical perspective of my colleagues in the
engineering world.  I certainly understand the reality that there aren't
enough skilled engineers to be involved on all sprinkler projects. To
say the typical "performance spec" is criminal may be excessive (maybe
they couldn't get enough fee to do the project justice...?) But I do
know that all engineers who rely on their blanket statement about
systems "meeting code" (but don't have the ability to verify compliance)
to are teed-up nicely to lose the litigation battle should a fire ever
occur. As Chris has reminded us, there seem to be an inordinate number
of screwed up systems out there, so it's really a wonder why more
engineers aren't brought to task through litigation.  Sometime I wonder
if it is because of the ironic fact that "everyone" knows the mechanical
engineer is not the expert - it's the sprinkler contractor.  So
engineers are forgotten when problems arise...???

Don't mean to tangent into another PE-bashing thread, but it just peeves
me that there are "professionals" getting paid for being lazy fools.

Subject: Do you look up?

I imagine, like me, you all (ya'll for some of you) on the very rare
occasions you are not working look around at sprinkler systems where you
live, shop and play. 

 

It's a very rare occasion I don't see something that appears deficient.
For
example, in a grocery store the one head on the back side of the main is
missing over HPS and a mess of piping creating a ceiling without heads
under them, at a Home Depot 190 psi on the wet side of an auxiliary dry
valve, or the local high school with sidewall heads about 15-20' down
from the peak of the very large skylight.  This is all in the last two
days as an example but see similar all the time.  

 

The sad part is I'm not really trying.  What if I had the plans and
calcs, how much more would there be?  Or really looked at the whole
building instead of a casual look at where I happen to be?  Or the scary
part what if I actually considered the hazard vs. the design?  

 

I also realize two issues - most times what I see probably won't cause
the system to fail in a fire IF that is the only thing wrong.  There is
a "probably" and an "if " in the last sentence which means there are
cases
that will fail, just not many IMHO.   And second we make mistakes too.  

 

The heads at the peak - just because an AHJ didn't call it a deficiency
doesn't mean it's OK.  Certainly it is possible there is a documented
and proactively approved alternate method out there on this but I
strongly doubt it.  Now I'm sure the missing head has a perfectly
rational explanation of how it got like that.  The W.O. is there and it
must be plugged or the system is off.  It's not a TI thing long after
the original construction; this is a very new building.  Can't
rationalize how you get 190 psi by accident or approval.  

 

MN is more regulated than most (but not all) areas.  Do you see this
stuff
too?  What if anything can you really do about it?
