Earthworks Calculator for iOS

Calculate the most cost effective production rate for earthworks by adjusting the number of trucks required.Compatible for iOS 7 and iOS 8. Calculator can use both imperial and metric units. Currency and number format are location specific.Use this pocket estimating tool to help make decisions on site like: A truck is unavailable today, what will that do to my production rate? The excavator bucket cycle has decreased, what will that cost me? Is it more cost effective to use fewer trucks that have a higher capacity? Do I hire the expensive excavator operator with a better cycle time or the cheaper one? What will increasing the time for breaks for an excavator operator do to my production rate?Definition of terms: Haul Distance: The distance between the excavation site and the fill / spoil site (one-way). Average Speed: The average speed of the trucks along the route between sites. Truck Volume: The amount of spoil/fill a truck can haul. Dump Time: Extra time required by truck to manoeuvre at fill / spoil site. Can be zero. Bucket Volume: The volume of the bucket / scoop of the excavator. Bucket Cycle: Time to load bucket + swing with load + dump load + return swing. Productive Time: The average number of minutes within an hour that are productive during excavation. Actual Production Rate: The production rate taking into account the number of trucks.
