mass haul export

A quantity of the mass earthwork material to be hauled and dispersed to a location where it is needed (which is generally associated with the same construction project) from a specific station along a corridor construction job site. The material is to be removed from the corridor's mass earthwork volume, independent of those materials that may be sent to waste sites. The mass haul export volume must be used on the subject construction project; excess material exported at a location must then be hauled to other locations until used; a deficit caused by export needs to be compensated for by the system. Exports and imports are used to evaluate the sharing and movement of mass earthwork materials between different aspects of the same construction project, each analyzed using a different corridor model.
