Fire Protection System Design Analyzer
Analyze sprinkler designs for NFPA code compliance and hydraulic performance
What You Can Do
You can rapidly review fire protection system designs by cross-referencing applicable NFPA codes, calculating system hydraulic demands, validating component selections, and identifying compliance gaps. The skill automates technical verification tasks—from pump sizing and sprinkler head spacing to water supply adequacy and backflow preventer specification—reducing manual review time and design errors during development and plan review phases.
Features
Computes pressure drop, K-factor verification, and system demand analysis across wet and dry sprinkler layouts
Cross-references designs against current NFPA 13, 14, 25, and 72 standards with specific requirement citations
Verifies sprinkler heads, pipes, fittings, valves, pumps, and controllers meet specification and performance requirements
Compares available flow and pressure against system requirements and hazard classification demands
Reviews pump performance curves, sizing calculations, and driver adequacy
Validates sprinkler spacing, obstruction clearances, and hazard area classification compliance
Checks backflow preventers, alarm devices, and ancillary component specification
Assesses code and performance implications of design changes or post-incident modifications
Example Output
Example 1: Hydraulic Demand Report
- Most remote sprinkler: K=5.6, operating pressure 70 psi, flow 25 gpm
- Pressure drop through 2" main: 8.2 psi
- System total demand: 450 gpm @ 105 psi
- Required pump curve: Must deliver 450 gpm at 105 psi (✓ Spec'd pump meets requirement)
Example 2: Code Compliance Finding
- Sprinkler spacing in warehouse: 12' × 15' (✗ Non-compliant per NFPA 13 Table 8.6.2 for light hazard—max 225 sq ft per head, current layout = 240 sq ft)
- Recommendation: Reduce spacing to 12' × 12' (144 sq ft) or increase head K-factor to 8.0
Example 3: Component Validation
- Backflow preventer: Double-check valve RP (✓ Approved for this occupancy per NFPA 13 Section 7.2)
- Main drain: 1.5" (✓ Adequate per NFPA 13 calculation: demand 450 gpm requires 1.25" min)
