Dominick J. Dunnigan, director of marketing for Oak Contracting, attributes that success to building relationships that gain repeat clients and a K-12 market that was not hit as hard economically as other segments.

“The money and the spending are still there” in building schools, Dunnigan says.

Oak constructs schools, churches and university projects throughout the state. In 2009, the company built the $66.7-million, 262,424-sq-ft Bel Air replacement high school; the $71.3-million, 268,354-sq-ft Edgewood High School; and the $24.3-million, 103,052-sq-ft Deerfield Elementary School, all in Hartford County. It continues working on the $62.3-million, 266,046-sq-ft Linganore High School in Frederick, Md., and began site work on the $59.2-million, 227,971-sq-ft George Washington Carver Center for Arts and Technology in Baltimore.
