ABSTRACT
The earthwork plays a vital role in road construction
projects. The planning of certain aspects of the
earthwork process, such as the transportation of
excavation material and the choice of construction
equipments for cutting and filling, is only inad-
equately supported by the existing IT system. The
given solutions that currently function as a plan-
ning basis are the 2D vertical and 2D horizontal
alignments and the 2D mass profile containing the
amount of cutting and filling materials and the
approximate positions (centre point) of the cut and
fill areas. Many decisions, like choosing the number
and the type of excavators and trucks required,
are made on the basis of experience from previous
projects. However, this often leads to over-or under-
estimating the capacities needed for the project
concerned, which may result in delays or increased
costs, respectively.
