In the middle of the 1960s, Brooklyn Union Gas Company invented the air lance, air compressor, and vacuum truck as a more efficient way to dig and lower the price of the 30, 000 street openings required annually for gas distribution pipe replacement. Dravo Corporation of Pittsburgh, Pennsylvania created the AirSpade, a specialized air tool for digging, as a result of their experiments. Dravo split off Briggs Technology, Inc. As a separate business in 1985 to market this novel approach. In the 1980s and 1990s, additional utilities like Baltimore Gas & Electric, PECO, and Pennsylvania-American Water began to accept it generally. Thousands of experts across the world now use AirSpade as the gold standard for the business.
