JNG construction was founded in 1971 by James N. Giammarino. General excavation and utility work were the areas that James had expertise in from working with his grandfathers and fathers general construction business in Binghamton NY from a very early age. These areas of business opened the doors for opportunities in the petroleum and service station industry.

Through hard work, quality service and a nice smile James created many good relationships in the petroleum industry. This helped propel JNG construction to focus on pump, tank and service station work as our primary business interest. Pump and Tank work for Major oil companies paved the way for JNG to start building complete sites including convenience stores, service stations and interior renovations.

New to industry sites and raze & rebuilds are completed in house as we employ skilled craftsmen in all facets of construction trades including carpenters, electricians, plumbers, masons and operators. Over the years JNG has accumulated a large fleet of equipment that is required to be proficient at pump and tank services. This includes everything from large earth moving machines down to specialized pipe threading equipment.

Environmental remediation and clean up became a major focus for the large oil companies and in turn became an important part of the services that JNG construction offers. JNG construction removes storage tanks and contaminated soil for residential, commercial and industrial institutions throughout the North East US. We also work hand in hand with several environmental engineering consultants to be able to provide all of the necessary testing and analytical work required by today’s governing bodies.

In the 2000’s JNG construction purchased the necessary equipment to start self performing excavation support systems. This included temporary sheet piling and bracing. Once the news of this new service got around, competitors and new clients alike began to call on JNG to perform their excavation support installations also. This new service began to grow and some more specialized equipment was purchased to be able to perform more extensive scopes of work.

Geotechnical construction became another of JNG constructions specialized services that is now offered. We perform complete engineered SOE’s including but not limited to sheet piling walls and soldier pile and lag walls. These services also lead to large diameter drilling of caissons and secant pile walls. JNG now offers a comprehensive list of geotechnical construction services that we perform throughout the entire North East US.

JNG construction is still a small family owned business. We offer personalized attention for all of our clients specialized construction demands. Weather you need service in the petroleum industry or solutions in the geotechnical construction field, JNG construction will be here now as in the future to offer our years of experience, professionalism and quality service.
