Fuel Consumption Efficiency in Construction Equipment Operations: A Mixed Methods Analysis of Determinants and Practices

John Alvin M. Gabriel | Peter G. Narsico

Discipline: building

 

Abstract:

This study examines the key factors affecting fuel consumption effi-ciency in construction equipment operations. Using a mixed methods approach, it combines quantitative regression analysis with qualitative interviews of equipment operators. A survey was conducted to gather data on operator behavior, equipment maintenance, equipment condi-tion, worksite environment, and operator experience and training. Re-gression results showed that among these factors, only operator expe-rience and training significantly predicted fuel efficiency, with R² = .31. Other variables, such as operator behavior, maintenance practices, equipment condition, and worksite environment, were not statistically significant predictors. Qualitative interviews supported these findings. Operators emphasized the importance of situational awareness, expe-rience, and task-specific adjustments in saving fuel. Common strategies included managing engine RPM according to workload, shutting down equipment during idle periods, and using neutral gear on downhill slopes when safe. These practices rely more on operator judgment than on technical specifications. While maintenance, equipment condition, and environmental factors were frequently mentioned, their influence appears indirect or context-dependent. This suggests that technical im-provements alone are insufficient without skilled operator input. The study concludes that operator training and experience, play a central role in fuel efficiency. It recommends that construction firms invest in targeted training and behavior-based monitoring to promote sustaina-ble and efficient equipment use.
