Fire Protection & Life Safety
Last year, we provided life safety inspections to over 24,900 facilities. This includes fire extinguishers, kitchen systems, dry chemical systems, emergency lighting, fire alarm testing, and fire/smoke damper testing.
Whether for the immediate distribution of clean water or the safe transportation of unwanted waste, quality plumbing is a key component to any building.

Building controls – also called Building Automation Systems (BAS), Building Automation and Control Systems (BACS), or Building Control System (BCS) – have quickly become vital in maximizing efficiency, sustainability, and profitability in today’s buildings.
