The Croton Water Treatment Plant is a clean water treatment plant located in the Bronx, and is the largest public works project in the history of NYC.  E-J was selected from amongst the largest and best known electrical contractors in New York City to take over and complete the Croton Water Treatment Plant Project.  E-J’s engineering centered approach to project execution, extensive successful large project experience and a world class team ready to go to work were the primary differentiators that earned E-J the contract.

Upon its completion, the Croton Project will supply 10 percent of New York City drinking water and will have the capacity to treat 1.2 million cubic meters of water per day, improving the quality of the drinking water.

E-J was responsible for all low and medium voltage electrical distribution, controls and auxiliary and life safety systems procurement, integration, design and installation.  The electrical installations included the following quantities and engaged more than 250 IBEW Local 3 Craftsmen:

>10M Linear Feet of Wire and Cable

>1.4M Linear Feet of Conduit

>20,650 Linear Feet of Cable Tray

The Astoria Energy Phase II Expansion Project added a new 540MW to the 1000MW facility, consisting of 2 GE Frame 7FA Gas Turbines and 1 GE D11 Steam Turbine Generator. E-J’s complete scope included 345kV overhead lines and GIS switchgear, PDC’s throughout the plant, air cooled condenser, HRSG, GIS bus, fire alarm, and all electrical work for instrumentation. Installation included 100,000 ft of underground conduit, 100 miles of electrical cable and 25 miles of above ground conduit.

E-J supported the EPC contractor with design assist starting 12 months before construction. During the design phase, the EPC contractor’s electrical designers incorporated E-J’s vast power plant knowledge by working hand in hand with E-J’s engineering team at their home office.

Because of the project’s fast track schedule, E-J was tasked to complete the Above Ground Electrical package within 10 months. Due to the compressed schedule and small plot of land, E-J employed “just in time deliveries” and worked multiple shifts in order to meet deadlines.

Installation of (6) six new General Electric LM-6000 PC Sprint aero-derivative gas turbines with SSS Clutch, and balance of plant facilities operating in simple cycle mode. Upgrade will provide an additional 300-megawatts of power to the neighboring communities during the peak demand periods and subsidize the base load plants.  Other installations include medium voltage switchgear and cabling, control and instrumentation systems as well as lighting, heat trace, lightning protection and security systems.

Installation of (3) three GE LM6000 Natural Gas Turbine Peaking Plants.  The plant was designed to provide an additional 150 mega-watts of power to the neighboring communities during the peak demand periods and subsidize the base load plants.  Other installations include medium voltage switchgear and cabling, control and instrumentation systems as well as lighting, heat trace, lightning protection and security systems.

The Hunts Point Wastewater Treatment Plant is one of the largest of New York City’s 14 water pollution control plants. The plant treats wastewater from a 16,000-acre area located in the northeast part of the Bronx and has a dry weather flow capacity of 200 million gallons per day and a peak wet weather capacity of 400 million gallons per day.  The project included numerous plant automations and the installation of a polymer addition system to upgrade the plant to comply with federal and state water quality controls in the east river

Electrical work upgrades and installations included new MCC equipment, outdoor distribution center to power existing buildings, lighting and a 480v sub-distribution in various buildings located throughout the plant.  The various systems installed included lightning protection, security and heat trace, all located in Class 1 Division 1 environments.

E-J was additionally responsible for the development and implementation of a Health and Safety Plan (HASP). The discovery of lead and asbestos throughout the project forced the team to remain solution oriented to push the project forward, while maintaining high safety standards and contract required remediation.

The work at the NYPA500 project included the erection, installation and testing of (2) 200MVA GSU, (1) 234MVA GSU and (2) auxiliary transformers, in addition to the installation and testing of (1) isolation transformer and (3) excitation transformers.

Dead end and PT structures along with associated 138kV switches were constructed to connect two of the three GSU transformers to the overhead transmission lines fed from the Astoria West substation. For design diversity, a pothead structure along with the associated switches was assembled to connect the third GSU to an underground 138kV feed which was also derived from the Astoria West ring bus.

The low side of these GSU transformers utilized a field welded 18kV Isophase bus to make the necessary connections to the combustion turbine and steam turbine generators as well as the auxiliary transformers. Power from the auxiliary transformers was delivered to the 4160V switchgear via a 5kV cable bus.

New 800,000 sq. ft. mechanization facility required as an extension of the existing Morgan Station. The project involves a high level of coordination and intense scheduling. Our installation involves a 480 volt Con-Edison service and distribution, lighting, fire alarm, temperature control, security systems and a 400kW generator.

As a member of the design/build team, we continued to evaluate time and cost saving ideas as the construction progressed, completing the project on time and under budget.

Power and control wiring for four new “GOSS” printing presses. Each press consisted of seven printing stacks. Installed over 2 million feet of power and control cables in 6000 feet of cable tray.

Furnish & install 13.8kV, 480V, 120/208V distribution equipment and feeders & circuitry. Furnish & install UPS, fiber optic, direct transfer trip and automatic control systems and motor work.

Rehabilitation of all electrical and mechanical ventilation equipment. This project is the total replacement of a fully redundant electrical and mechanical system for the ventilation of the Holland Tunnel. Equipment being replaced is medium voltage switchgear, 480V switchgear and motor control centers. This equipment resides in four buildings, two New York, two in New Jersey. Equipment removals and replacements must be staged perfectly so that there is no interruption to tunnel service.
