1) Looking back at my building notes this building is 78000+ sf. I see that the stand alone stand pipes and sprinkler piping branch off the main bulk riser. Then looking at sprinkler piping for floors 1-4 (pages FP1.1-FP1.4) I do NOT see how the sprinkler is broken in to separate systems either by floor or so that it serves less than 52000sf. 13r:6.1.1 Show how the 13r sprinkler system does not cover more than 52000sf.
Wednesday, July 13, 2022 Response to comments indicate "See NFPA 13r handbook discussing the intent of section 6.1". Below this response was 13r:6.1. Essentially the 52000sf limitation is per floor. The over all building SF is 78000sf.

2) Plans show SIN R3516 head with k factor 4.9 being used. Manufacturer spec sheet page 3 for this SIN shows max coverage area of 16 x 16. How is this head being used in many locations that appear to exceed the 16x16 max coverage area. Example of SOME spaces: 20 x 20 bedrooms, living room areas in 2 bdrm on corners of building, corridor heads are located 18' apart. 13r:6.4.6.3
Wednesday, July 13, 2022 Response to comments indicate "Reliable 4.9k pendant is listed for up to 20x20 spacing. The sprinkler spacing is defined as 18x18 unless noted otherwise. You may be looking at the 3.0k pendent on page 3 of the cut sheet which the spacing is limited to 16x16 spacing."

3) Page FPD.2 shows detail for antifreeze. Confirm this is a standard detail and that this isn't being used in this system. If antifreeze being used in this building, point out where antifreeze will be used.
Wednesday, July 13, 2022 Response to comments indicate "Only building 1 has the antifreeze system. This sheet is updated to state this detail applies only to building 1."

4) I am confused looking at typical floor control detail (stand pipe) on upper left of FPD.1, it shows a stand pipe with a connection above the hose connection looks like what would goto supply floor sprinklers. Upper mid page of FPD.1 also shows building elevation detailing the stand pipe for buildings 1- 3. But page FP1.0 shows the stand pipes are not combined with the sprinklers. Looking at piping the bulk main splits and feeds the stand pipes and then the sprinklers separately.
Either: a) update typical floor control detail to show just stand pipe with no sprinkler floor tie in and show this tie in on elevation detail upper mid page of FPD.1 for this building 5 OR b) clarify what that tie in is on the typical floor control detail on upper left of FPD.1 and show this tie in on elevation detail upper mid page of FPD.1 for this building 5 OR c) update the piping pages to FP1.0-FP1.4 and stand pipe elevations showing correct piping layout for this building 5.
Wednesday, July 13, 2022 Response to comments indicate "Detail regarding the floor control assembly has been removed."

5) Unable to locate gauges at main drain connection and top of each stand pipe. 14:5.5.1
NOTE: I will then be looking for shut off valve and drain at each gauge. 14:5.5.1.2
Wednesday, July 13, 2022 Response to comments indicate "Pressure gauge is located at the top of each standpipe. Please see the standpipe cross sections shown in the details sheet."
I am still not seeing the gauges, shut off valve and drain at the top of each stand pipe. What page number? Where? At the top of FPD.1 there is small blurred print at the top of the stand pipes that is illegible. Is this what you mean? What does it say?

6) Where are the isolation valves for each stand pipe? 14:6.3.2
Wednesday, July 13, 2022 Response to comments indicate "Isolation valves are shown on the bulk standpipe layout sheet. Also each isolation valve is labeled in the keynotes section of the drawing."
I found it on FP2.0 Keynote 4.
