@buildwitt: DREDGING — What is dredging? Dredging is the process of removing accumulated sediment from the bottom of bodies of water! In this case, @greatlakesdredge is actually removing rocky outcrops after underwater blasting in the Boston Harbor! — The Liebherr 996 is the largest Backhoe Dredge in the United States of America, and the second largest backhoe dredge in the world! #dredge #excavator #mining #heavyequipment #operator
