Heavy duty diesel (HDD) construction equipment plays an important role in building and rebuilding Indonesia's infrastructure and has a significant impact on national energy consumption in the form of diesel fuel. This paper demonstrates an 'energy-productivity' (ENPROD) model, a practice-ready methodology in developing an energy estimating model for HDD equipment that establishes a baseline of current fuel use based on the equipment's productivity rates. The model was formulated by using the productivity model to obtain the total duration of work, and combined with the NONROAD's brake specific fuel consumption (BSFC) to gain the fuel consumption rate in term of liter per horsepower-hour (liter/hp-hr). ENPROD model is good to be used as a benchmark for estimating fuel use from some certain types of construction equipment performing earthwork activities. Based on the methodology presented in this paper, the results revealed several trends related to total fuel use of the equipment. © 2016 Author(s).
