Abstract

Concreting operations commonly utilize a large range of equipment that generates a considerable amount of greenhouse gas (GHG) emissions. Equipment idle time is considered as a non-productive time that it increases the fuel use and emissions without any production. Reducing idle time in operation implies the opportunity to improve productivity, cost efficiency, and emissions reduction. Continuous efforts have been made to determine the efficient solutions in reducing emissions of construction operations. Existing publications on concreting operations have focused on cost and production, with little attention being given to emissions. In response to this need, this paper aims to examine the influence of equipment idle times towards emissions, costs and production performance. This paper investigates the link between idle time, equipment utilization, production, emissions, costs, and optimum equipment configurations. Case study data along with Monte Carlo simulation are used to develop a model for cyclical concreting operations. The results highlight that eliminating most of the truck waiting time translates to higher utilization of both trucks and loader, thus increasing the non-idle fuel use and consequently increases emissions.
