About this Gig
Are you a fire protection contractor, engineer, or design firm that needs accurate, AHJ approved fire alarm riser diagrams and calculations fast?
I specialize in NFPA 72-compliant fire alarm riser diagrams, battery standby calculations, and voltage drop analysis for commercial, industrial, healthcare, and high-rise occupancies.
What you get:
- Detailed riser diagram showing zoning, circuits, devices, and panel connection
- Battery standby & alarm load calculations (24/60-hour requirements)
- Voltage drop calculations for NAC/SLC circuits
- AutoCAD/PDF deliverables ready for AHJ submittal
- Code-compliant documentation (NFPA 72, IBC, local AHJ standards)
Why work with me:
I understand that fire marshals reject submittals over calculation errors costing you time and money. I deliver clean, accurate, submittal-ready drawings the first time, with manufacturer-specific device data (Notifier, Edwards, Simplex, Fire-Lite, Honeywell) when needed.
Whether you need a single riser diagram or full calculation support for permit approval, I bring precision and code knowledge to every project.

FAQ
Do you provide calculations that meet local AHJ/fire marshal requirements?
Yes. All calculations follow NFPA 72 standards and can be adjusted to match your local jurisdiction's specific submittal requirements.
What information do you need from me to start?
Building floor plans, device count/locations, panel make/model, and circuit lengths. Full list provided in the requirements section after ordering.
Can you work with my existing AutoCAD or Revit files?
Yes, I can work from your existing CAD files, PDFs, or even hand-marked floor plans.
Do you sign/stamp drawings as a licensed engineer?
No I provide drafting and calculation support only. If your jurisdiction requires a PE stamp, that must be obtained separately through a licensed engineer.
What if my submittal gets rejected by the fire marshal?
I offer a discounted resubmittal revision add-on to quickly correct and resubmit based on AHJ feedback.
