Design and Build

We provide a feasibility study, insurance requirement analysis, cost-benefit analysis, hydraulic calculations, and computer-aided program (CAD) sprinkler drawings.

We design/build, install, retrofit, and repair sprinkler systems in the following types of buildings:

Residential

Single Home
Multi-Dwelling Units
Mixed-Use Buildings
Apartment Buildings

Commercial

Office Building
Retail Store

Industrial

Warehouse
Parking Garages

Institutional

Senior Living / Assisted Living
Nursing Homes
Hotel
Churches

If you'd like a proposal for a sprinkler system for your property:

Email: Bids@dndfp.com with the following information:

PDF drawings of your building
Contact Info: Name, Business Address, Email, Phone number
Description: ie) I need a proposal for a sprinkler system in my new house

If a site visit is required to your property, our Project Estimator will reach out to schedule an appointment to see the conditions for your new or existing sprinkler system.

Types of Sprinkler Systems

Wet Sprinkler System

The most common of all fire sprinkler systems, wet sprinkler systems consist of water that is constantly maintained within the sprinkler piping. When a sprinkler activates, this water is immediately discharged onto the fire.

Wet sprinkler systems are best used for:

Churches, Schools, Event Centers, Retail stores, Healthcare Buildings (Senior living/assisted living), Multi-Living and Dwelling Units (apartment buildings, condominiums, and hotels)

Dry Sprinkler System

Dry Systems are typically used when wet pipe systems can't be used because of the chance of freezing temperatures or when temperatures cannot be maintained above 40 degree Fahrenheit.

Dry Sprinkler Systems typically have pipes pressurized under air or nitrogen, have a dry valve, and must be pitched so water doesn't freeze within the pipes.

Dry sprinkler systems are best used for:

Garages, Loading Areas, Unheated Warehouses, Cooler Storage, Outdoor Enclosures

Anti Freeze System

Anti-freeze systems are are typically used in wet pipe systems to keep the water from freezing. In places where the temperature may drop below 50 degrees, an anti-freeze loop can be added to the sprinkler pipes.

Anti-freeze systems must only use anti-freeze listed for the purpose of use in fire sprinkler systems.

Fire Pump

Fire Pumps are typically used when a building's water source does not have adequate water pressure for the protection of a system. Even residential sprinkler systems may need a small fire pump.

Fire pumps are typically used in:

Nursing Homes, Multi-story Apartment buildings, Warehouses, etc.

Standpipe System

A standpipe system is a fire hydrant system inside a building. It allows fire fighters to connect hose to a water source to manually fight a fire without having to run the hose from the outside into and through the building to the fire. Standpipe systems share the water supply with the fire sprinkler.

Applicable codes: NFPA 13, 14, & Life Safety Code.

NFPA classifies standpipe systems into 3 types: Class I, II, III

Standpipe systems are typically used in:

Tall or very large buildings.
