Location:
Sewaren, New Jersey

Owner:
PSEG

Year Completed:
2017

In order to support the electrical system reliability, PSEG made the decision to build a new 540-MW, dual-fuel combined cycle power plant at the existing Sewaren Generating Station site in Sewaren, New Jersey. This project would replace Sewaren Units 1,2,3, and 4 after almost 70 years of use. The new combined-cycle plant consists of clean, state-of-the-art generating technology which includes full emissions control. Ferreira performed all of the underground (anchor bolt down) civil work to support the new power plant. Ferreira’s scope of work included installing 58,500 SY of vertical wick drains, 3,830 LF by 48 feet in length of sheet pile wall, and 171,000 CY of imported site fill that elevated the site 15 feet to eliminate potential damage from future storms. In addition, Ferreira was contracted to install the entire substructures package which included 4,200 pipe piles, concrete foundations requiring over 30,000 CYs of concrete, 4 million pounds of reenforcing steel, 32,000 LF of underground mechanical piping, and 165,000 LF of 2” to 6” PVC and RGS duct banks (concrete encased). Ferreira installed all the site drainage and final site restoration items.
