S&J Construction Co. was founded in 1981 by Simone and John Kapovich Sr. in South Holland, Illinois. John retired in 1999. Simone purchased his share of the company and maintains 100% ownership. The main office resided in South Holland, two other locations were also rented by S&J to house equipment and personnel. In September of 2013, S&J moved to its current facility in Oak Forest, Illinois. The move to the new facility enabled S&J to join the bridge division with the signing and drilling division and all of its equipment under one roof.
