Earthwork Logistics Optimization in Road Construction Project
Earthwork requires the movement of large quantities of soil from borrow areas to fill areas, typically for embankment and subgrade preparation. These operations contribute to a significant component of a project and deal with the balancing of cutting and filling volumes cost-effectively. Earthworks contribute about 25% of the total cost of a road project, out of which one-fourth is spent on the earthmoving operations alone. Careful planning of earthmoving operations can make considerable savings in the logistics cost due to many feasible options available to the project team. This paper aims to demonstrate the optimization technique’s ability to provide cost-efficiency in managing the logistics of raw material (earthwork) supply chain in the road project. This study focuses on planning the logistical operations of earthwork for a 14 km road construction project between two Indian towns. A large quantity of soil is needed to be procured to prepare these embankment and subgrade layers for which 14 borrow sites were identified. This paper presents the transportation problem as a linear programming formulation for the optimal planning and distribution of earthwork from borrow areas to different segments of the road (fill areas). The objective function is to minimize the total cost of transportation of soil from borrow sites for the construction of embankment and subgrade layers constrained by the total demand at construction sites and total supply at borrow sites.
