About this project
In 2014, Liesfeld moved 900,000 Cubic Yards of earthen material at the Dulles International Airport. The project entailed relocating a stockpile generated from years of runway construction out of the way at the new Metro Railway Maintenance Facility at the end of the new Silver Metro Line. The grading crews averaged over 14,000 Cubic Yards per day and hit 30,000 Cubic Yards per day during high production periods. Liesfeld also performed additional work such as building haul roads and other site preparation measures.
