The project

Four days from failing grid test tofull compliance

Benchmark: 51% coverageAcceptance: 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.
