AirEng, a nyb subsidiary, has been busy lying the groundwork for mechanical and electrical construction for the Gwalia project. They are providing a turnkey ventilation system for Australia's oldest and deepest golf mine, including primary fans, the electrical power unit, and civil construction systems. One major challenge is getting proper ventilation to the workers underground. The fans are about 60 feet high, providing static efficiencies above 85%. The foundation consists of over 1,5000 tons of concrete and 300 tons of steel, with over 50 full semi-truck loads of fan equipment being brought in. Pictured is some of the work completed so far, with the expected completion date of late 2019.
