Engineering News-Record (widely known as ENR) is a weekly magazine that provides news, analysis, data and opinion for the construction industry worldwide. Its subscribers include contractors, project owners, engineers, architects, public works officials and industry suppliers.

Since 1964, ENR has compiled and published rankings of the largest 400 construction and engineering firms annually, measured by gross revenues and over the past fifty four years, the rankings became a matter of pride and a matter of competition for contractors throughout the nation.  Hunzinger is the only local contractor that has been on the list every year since its inception in 1964.
