Project Description

DB_NatGrid Bayshore_LEN0698The design and construction of a new 3,000 s.f. single-story masonry and steel framed building to house ozone generation equipment for National Grid. The building is designed to house sophisticated equipment to remove contaminants. The building is located on a high traffic corner lot in Bay Shore and borders on a residential area. The project was subject to rigorous site plan and architectural review by local governing agencies, and was well received by the Town of Islip.

Full Architectural/Engineering services, including surveying, permitting, drainage, site grading, landscaping, plumbing, sophisticated HVAC systems, electrical, and architectural design of both exterior and interior elements, from scope phase through construction and closeout.
The overall aesthetics of the building are more significant than typical treatment facilities.

D&B’s project responsibilities included design of the following systems:

Power Distribution

A new 13kv electrical service routed to a PSEG padmount transformer was provided to serve the Plant. From the transformer, a 480/277 volt, 400 amp underground service was installed to main distribution panelboard located inside the building. An automatic transfer switch for the emergency generator transfers power to building HVAC, lighting and life safety loads upon PSEG power failure.

Emergency Power

A 42 kw natural gas generator is located outdoors and housed in a weatherproof skin-tight enclosure. The generator provides power to the building HVAC, lighting and life safety loads via the automatic transfer switch inside the building.


The interior building lighting included fluorescent and metal halide fixtures, as well as emergency and exit lighting. A parking lot and site lighting system, consisting of pole mounted metal halide fixtures, was also included.

Building Fire Alarm System

A fire alarm system was designed for the facility. The system includes HVAC shutdown interlocks and central station monitoring.
