Abstract
Earthworks are an integral part of the vast majority of infrastructure projects. As it is commonly defined in the construction field, earthwork operations basically consist of excavating, moving or placing large quantities of soil or rock from one particular location to another. Also included in the extensive category of earthworks are activities, including but not limited to, the preparation of foundations and embankments, and the disposal of excavated materials. The diverse processes involved in earthworks highly contribute to greenhouse gases (GHG) and particulate matter (PM) emissions which cause local air quality degradation, as well as global warming. This research is primarily concerned with the identification of sustainability indicators regarding earthwork machinery deployment and operations. Sustainability indicators with respect to earthwork machinery operations vary according to different operating modes commonly characterized as idling mode, moving mode and working mode. This research provides an assessment of the relevance of sustainability indicators to achieving more efficient operational levels and their respective environmental impacts. For instance, particulate matter (PM) emissions, Greenhouse Gases (GHG) emissions and excessive energy consumption, all harm the environment from the construction site to its surrounding areas. Thus, such parameters may serve as indicators of the levels of operational and environmental efficiency being achieved. Accordingly, this study focuses on promoting sustainable earthwork operations by assessing the sustainability level of heavy duty construction equipment with respect to their engine efficiency and the potential negative impact on the environment due to emissions. Promoting a cleaner environment is important for a healthier future; and Identifying construction equipment as one of the main sources of air pollutant emissions is a feasible approach. The implementation of the proposed methodology will aid the decision making process by helping to explain, control and predict events.
