Project Brief

Holmdel Township renovated its EMS building on Crawfords Corner Road to give the crews a working station around the clock: dorm rooms, locker rooms, a kitchen and dining lounge, a training and meeting room, laundry, offices and the vehicle garage. KeRi was the MEP and fire protection engineer to Netta Architects.

Two new indoor air handling units on the mezzanine serve the building: a 5,500 CFM gas-heated unit and a 2,200 CFM electric-heated unit, each with its own air-cooled condensing unit on grade, variable speed return fans, and MERV 8 pre-filters followed by HEPA final filters to keep the living and training spaces clean for crews coming off calls. A ductless split system cools the IT room, gas-fired unit heaters warm the garage storage areas, and a 12 ft high volume, low speed fan moves air across the 3,600 SF apparatus bay.

Because the station has to stay in service during an outage, the existing generator was replaced with a 130 kW natural gas standby generator carrying the whole building through two automatic transfer switches, one for the emergency lighting panel and one for the 400 A distribution panel, behind a new 400 A service. The sprinkler heads were replaced throughout with a new fire department connection, and plumbing covered the locker rooms, kitchen and laundry.

MEP Engineering Scope

What We Engineered

MEP and fire protection for the EMS building renovation:

• Two mezzanine air handling units, 5,500 and 2,200 CFM, with HEPA final filtration
• Ductless split cooling for the IT room and gas-fired unit heaters for garage storage
• 12 ft HVLS fan for the 3,600 SF apparatus bay
• New 400 A electrical service and distribution
• 130 kW natural gas standby generator with two automatic transfer switches
• Sprinkler heads replaced throughout with a new FDC, plus locker room, kitchen and laundry plumbing

The Challenge

An EMS station is lived in around the clock and has to keep running when the power goes out, while crews return from calls into shared sleeping, eating and training spaces.

Our Solution

KeRi paired HEPA-filtered air handling with a 130 kW natural gas generator that backs up the whole building through two transfer switches, on a new 400 A service.
