Fire Sprinkler Plan Design Needed

I need a code-compliant fire-sprinkler layout drawn up for my place of business. The premises are under 1200 sq ft and, unfortunately, I have no existing architectural drawings, so the project will start from a blank slate. You will either have to create a base floor plan from site measurements (which I can help gather or arrange virtually) or advise me on the exact data you require.

I expect a complete, permit-ready package that satisfies News York City jurisdiction’s adoption of NFPA 13 and any local amendments. The final documents must be suitable for submission to both the building department and my chosen sprinkler contractor.

Deliverables I will check for:
• Scaled floor plan with sprinkler head locations, pipe sizing, and zone annotation
• Riser detail and legend of all symbols used
• Hydraulic calculations and material specifications
• PDF set for permit plus editable CAD (DWG or similar) files

Please outline your process for gathering field dimensions, confirm the software you use (AutoCAD, Revit, or equivalent), and state any required turnaround time for reviews so we can keep the project moving smoothly.
