Due to tight production schedules, we deployed two drill rigs and crews drilling approximately 50 holes per day keeping ahead of concrete placement and maintaining the general contractor's production schedule. As can be seen from the pictures this was difficult drilling due to water in and around the drilling excavation site, tight layout, and congested job site. Wet lignite lenses were encountered requiring us to drill past the lenses and utilize the tremmie pour method with all holes.
Aurora Water recently received recognition from Liberty Mutual for having a spotless safety record on the first contract for its Prairie Waters Project - Aurora's innovative and sustainable water project to deliver an additional 3.3 billion gallons of water to the city per year by 2010. Ludwig Drilling personnel received awards as part of that team.
