Yes...code required Class II & Sprinkler 30 years ago when building was built. Original pump is 500 GPM (locked up...and scrap) limited service 30 Horsepower. AHJ first required controller jump to internal auto transformer then came back with this 100 psi deal. Customers electric service and emergency gen set won't handle the load.
AHJ is saying he wants pump and standpipe now to comply with current 100 psi requirements...so I said ...ok...in that case he only needs a pump if his sprinkler demand on the 5th floor requires it. AHJ is now delaying approval of change out while he tries to manufacture a counter to our last submittal ....he has had it for 15 days now and seems to be stumped. BTW...5th floor calcs need the 500 gpm at 65 + city to work as piped. Best all around deal is to R & R existing pump/controler....owner has 3: identical buildings like this all built at the same time ...so we are trying to get the deal right the first time with the city.
