Four days from failing grid test to full compliance
Benchmark: 51% coverage — Acceptance: 100% passing
Clawson Manor is a 15-story senior-living co-op in Clawson, Michigan — the kind of building where first responders cannot afford a dead zone. Benchmark grid testing showed the high-rise failing emergency-responder coverage at just 51% in critical areas.
WZC performed the grid testing, then designed a COMBA CriticalPoint passive DAS in iBwave and coordinated the plan directly with the AHJ. With the design approved, the crew installed the system in four days.
The result: 100% passing coverage across the building, at a total investment of $67,500.
