************ yes, walls moved, and I believe the design area changed from 1,500 to 3,000, as this is a job on a military base whose last renovation occured in 1994. ************ > > > If the changes to the system are significant enough, is he providing a new > hydraulic calculation for the system?

This is something I feel should be on the plans. So I will do it, because the GC knows the AS contractor doesn't want to, and it will take a long tim. (The AS reluctance may be justified, depending upon whom you ask, the specs indicate some level of detail is required in documenting the source of water to the building, but I did not know the specs, when I asked the AS contractor to document this water supply information). ************* > As far as you asking for bracing, based on what?

I received them...not wrote them. these specs are vague...from previous thread the specs say to "describe seismic bracing, restraint and protection features for non-structural building systems and installed components." for new construction on another project at same site this sub and I worked together we put EQ bracing up on that project. that was a bit like pulling teeth getting the calcs complete. for this renovation, i stand corrected and back down, I change my mind. no EQ bracing...the pipe can fall down. Earthquakes happen in central Cally. **************** > > > > > Sounds like a big truckload of info needs to be coming from the EOR first. > As the reviewer you should not be doing the engineering on the job, and if > the contractor is slow in responding according to the GC, that's not your > problem. NFPA 13 doesn't specifically define what's part of a scope of work or not, the contract documents do. So you can't enforce NFPA 13 as his contract duty. Obviously he is obligated to install to meet NFPA 13 requirements, but 13 doesn't define the limits of work. If the EOR left vital information off his construction documents, then it's HIS responsibility to learn how to execute a protect correctly and provide the necessary information to the contractor so ultimately you have what you need to do a thorough review. The issue is, are you asking to do things that were not part of his contract? ************** that's the issue, that is why I asked for advice. thanks for helping scot deal excelsior fire _______________________________________________ Sprinklerforum mailing list http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
