Our Electrical Construction Division is at the heart of the company, dating back to its founding in 1911. O’Connell defines electrical construction as any and all electrical related services required to power and energize facilities and structures of any type and size—beginning at the service feeder, ending with the last outlet or fixture—we do it all. We electrically construct high rises, distribution warehouses, manufacturing facilities, universities, prisons, military complexes, power generation facilities, hospitals, casinos, airports, stadiums, data centers, cell towers . . . any type of structure or facility.

O’Connell Electric is a leader in LEED construction in New York State. We recently completed Syracuse University’s massive 230,000 square-foot Life Sciences complex and Rochester Institute of Technology’s College of Applied Science and Technology Building—bronze and gold certifications, respectively. Today we have several LEED projects in the works.

O’Connell keeps facilities running at peak performance through our custom maintenance programs. We provide periodic condition assessment reports with recommendations for upgrading lights, mechanical systems, and machinery with more energy efficient alternatives.

O’Connell provides the full electrical package for meeting the standard and technology driven needs of organizations today regardless of size, scope, and complexity. Continued improvement through training and education programs keep our managers and technicians up to date on industry technological advancements and customer requirements. Our tools and equipment are second to none. O’Connell’s track record of success is continuously demonstrated through safety, schedule, budget, and customer satisfaction measures. Repeat business has become our standard.
