Complete, code-compliant fire sprinkler design and shop drawings — engineered to pass plan check the first time and install cleanly in the field. Hydraulic calculations, stock listing, and detailing included, with a turnaround that keeps your projects moving.
Request a Free QuoteA great fire sprinkler design does more than satisfy the code — it saves your installers time, reduces RFIs, and keeps fabrication on schedule. Calculated Fire Suppression LLC produces fully detailed design packages for fire protection contractors, combining accurate hydraulic modeling with practical, buildable layouts drawn the way your crews actually install.
What’s included in a design package
- Working plans & shop drawings — plan, riser, and section views with full dimensioning and hanger/seismic detailing.
- Hydraulic calculations — remote-area analysis sized to the correct density/area or room-design method, with a clean calc summary.
- Stock list / material take-off — itemized pipe, fittings, heads, and devices ready for ordering and fabrication.
- Cut sheets & specifications — coordinated submittal data for the AHJ and general contractor.
- Revisions & back-check support — quick response to plan-check comments so approvals don’t stall.
System types I design
Familiar with all types of water-based fire protection across residential, commercial, industrial, and high-piled storage occupancies:
- Wet pipe and dry pipe systems
- Pre-action and deluge systems
- ESFR and in-rack storage protection
- Standpipe and hose systems
- Fire pump sizing and design
- Residential systems under NFPA 13D and 13R
- Antifreeze loops, foam-water, and water-mist applications
Designed to the right code
Every layout is built to the applicable edition of NFPA 13, 13R, or 13D and the adopted local amendments, with the occupancy hazard classification and water-supply data documented up front. That means fewer surprises at plan check and a design your installers can trust. If you only need a second set of expert eyes, I also offer independent plan review and consulting.
Why contractors work with a freelance designer
As a freelance fire sprinkler designer, I plug directly into your workflow without the overhead and long lead times of a large firm — which means competitive pricing, flexible payment terms, and a genuinely quick turnaround. I work with contractors throughout California, Idaho, and Arizona, and have delivered projects nationwide.
Frequently asked questions
What do you need to start a design?
Architectural/structural backgrounds (CAD or PDF), the occupancy and commodity information, and water-supply data (flow test or city data). If something’s missing, I’ll tell you exactly what to request.
How fast is turnaround?
It depends on size and complexity, but quick turnaround is a core promise — share your deadline and I’ll confirm a realistic schedule before we start.
Do you provide hydraulic calculations?
Yes — every design package includes hydraulic calculations and a stock list unless you request drawings only.
Which CAD format do you deliver?
Industry-standard fire sprinkler design software output, delivered as DWG and PDF. Let me know your contractor’s preference.
