In addition to that:
Make specs/plans job specific - they usually put general notes and details. We have one engineer that puts the same info on all and it reads any pipe 2" and under to be threaded sch. 40.. And the riser detail always shows alarm valve, OS&Y, retard chamber, water motor gong, etc. I know the engineer and he says these are general notes and details and we can make any changes we need to at design time as long as it is per the required codes for the project; local, NFPA, FM, etc. 90% of the jobs do not require this and we have had changes in our shop drawings denied based on the info on the plan not matching the engineer's info.

The details are easy for contractors to work through. The hard part is working behind BAD general info, incorrect code references, bad water supply data, heads laid out that are not even close and a contract that says you will comply with the (incorrect) drawings, etc. Greg On Thu, Mar 10, 2011 at 7:48 AM, Chris Cahill <[email protected]>wrote: > I'd combine Craig's 4 and 5 and add a new 5 water supply analysis. > Otherwise that is what the A/E should focus on. > > Chris > -----Original Message----- > From: <[email protected]> > Sender: [email protected] > Date: Thu, 10 Mar 2011 06:37:18 > To: <[email protected]> > Reply-To: [email protected] > Subject: RE: top five list > > Duane, > > When you say consulting are you talking about A/E firms? > > In real basic, simple terms (definitely not all inclusive): > > A/E Fire Protection Specialist: > 1.
