FAQ
Do you cover California specific code requirements (CBC / CFC)?
Yes. I design per NFPA 13, 13D, and 13R guidelines while accounting for California Building Code (CBC) and California Fire Code (CFC) specific amendments, including seismic bracing requirements and local AHJ submittal notes.
What information is included in the hydraulic calculation report?
The report details the design area, hazard group, density/area curves, friction losses (Hazen Williams formula), fitting equivalent lengths, required system pressure, and total flow demand (GPM) plotted against your water supply curve.
Can you help if the local fire marshal requests redline changes?
Absolutely. I provide support to revise and update drawings or hydraulic calculations based on formal plan check comments from the local fire department or reviewing authority.
Do you provide a PE (Professional Engineer) stamp?
I provide the complete design drawings, pipe sizing, and hydraulic calculation package ready for submittal. If your local AHJ strictly requires a wet or electronic PE stamp, your local engineer of record can review and seal the completed submittal package.
