This bulletin describes the information to be provided when plans are submitted for a building permit to install or modify a fire sprinkler system. Legible and readable working plans shall be drawn to an indicated scale (not smaller than 1/8 inch = 1 foot), on sheets of uniform size (11 inches by 17 inches minimum), with a plan of each floor. The scope of work must be indicated and the standards used must be referenced, including the edition (e.g., NFPA 13, 13D, 13R). Plans shall show those items from the following list which pertain to the design of the system. All details and information on drawing must be of sufficient size and clarity to be legible and microfilmed. Plans must not be submitted on a reflected ceiling plan.
Please note that only the drawings are microfilmed and that all pertinent information regarding the sprinkler system shall be on the drawings. Therefore any references to submittal specification sheets or hydraulic calculations are not acceptable.

16. Other sources of water supply, with pressure or elevation;
17. Underground pipe size, length, location, weight, material (complete description i.e. cement lined ductile iron), and point of connection to city main; the type of valves, meters, and valve pits; and the depth that the top of the pipe is laid below grade;
18. Piping provisions for flushing;
19. Approximate capacity in gallons of dry pipe system;
20. Pipe type and schedule of wall thickness;
21. Nominal pipe size and cutting lengths of pipe using center to center dimensions; Note: Where typical branch lines prevail, it will be necessary to size only one typical line.
22. Location, size and length of riser nipple or drop;
23. Type of fittings(including description i.e. 125# cast iron threaded fittings, mechanical joints, above/belowground) and joints and location of all welds and bends. The contractor shall specify on the drawing any sections to be shop welded (non-restraint type joint) and the type of fittings or formations to be used. For mechanical joints on underground piping provide thrust block size and details.
24. All control valves, check valves, drain pipes, and test connections including inspectors test assembly, also show 1/4" relief valve for grid systems;
25. Make, type, model, and size of alarm or dry pipe valve;
26. Make, type, model, and size of preaction or deluge valve;
27. Kind and location of alarm bells;
28. Size and location of hose outlets, hand hose, and related equipment;
29. The setting for pressure-reducing valves, include both static and residual pressures;
30. Information about backflow preventers (manufacturer, size, type);
31. SIN (Sprinkler Identification Number), manufacturer, manufacturer's model number, response type, temperature rating, sprinkler type, orifice size, and any other necessary identification information for all sprinklers used;
32. Temperature rating and location of high-temperature sprinklers;
33. Manufacturer's installation instructions and technical data for any specially listed equipment, including descriptions, applications, and limitations for any sprinklers, devices, piping, or fittings. This includes backflow preventers, fire pumps (including pump curves), and pressure reducing valves, special design systems and accessory devices.
34. Total area protected by each system on each floor;
35. Number of sprinklers on each riser per floor;
36. Total number of sprinklers on each dry pipe system, pre-action system, combined dry pipe-pre-action system, or deluge system;
37. Hydraulic calculations or pipe schedule design criteria;
38. For hydraulically designed systems, the information on the hydraulic data nameplate for the most remote area for each hazard;
39. Hydraulic reference points shown on the plan shall correspond with comparable reference points on the hydraulic calculation sheets. Outline/highlight remote area;
