Deep Pit Excavation | Contractor Talk
Hi, I am trying to get an idea of the equipment needed and timeline to excavate a 20x80 by 60 feet deep pit. I am assuming that 2 or 3 excavators will be used on benches to haul the soil out of the pit, about 30,000 CY. How many excavators should be used and how many yards of dirt can each excavator move in a day? Thanks
