The aim of planning earthworks is to provide a efficient and economical scheduling of the available resources. However, it is common for unforeseen situations to occur, as a result of breakdowns in mechanical resources, or adverse weather conditions, leading to the need to constantly reorganise the workflow on the construction site. This paper describes an innovative methodology to support the decision-making process throughout all construction phases, providing optimal solutions for resource allocation and corresponding costs and duration. During construction, support for decision-making is provided through sensor-based monitoring, which allows for a constant assessment of equipment performance. The system can provide suggestions for readjustments to resource allocation when necessary to ensure that work progresses optimally. The methodology is applied to a case study concerning the earthworks project for the construction of a motorway in Portugal.
