AI for Sprinkler Coverage Analysis

Sprinkler coverage analysis verifies that every protected area of a building has adequate sprinkler protection — correct head spacing, no obstructions within the clearance zone, and hydraulic calculations that confirm adequate water supply to the most remote area. AI automates this verification by reading the fire protection drawings and checking against NFPA 13 requirements.

The spacing and coverage check is geometrically intensive. Each sprinkler head has a maximum coverage area that depends on the hazard classification, ceiling height, and obstruction conditions. AI identifies each head on the drawings, calculates its coverage area based on the spacing to adjacent heads and walls, and verifies that no area within the protected space falls outside the coverage of at least one head.

Obstruction analysis is where many sprinkler compliance issues arise. Beams, ducts, light fixtures, and other elements below the ceiling can obstruct the spray pattern, creating unprotected areas. NFPA 13 has specific rules about when obstructions require additional heads or repositioning of existing heads. AI identifies potential obstructions from the reflected ceiling plan and coordination model, flagging locations where the sprinkler layout may not provide adequate coverage.
