Abstract

Current estimates of the actual productivity of
heavy construction machinery at a construction site are
not supported by an appropriate and widely used methodology.
Recently, for the purpose of estimating the actual
productivity of heavy construction machinery, visionbased
technologies are used. This paper emphasizes the
importance of estimating actual productivity and presents
a way (i.e. a research framework) to achieve it. Therefore,
the aim of this paper is to propose a simple research
framework (SRF) for quick and practical estimates of
excavator actual productivity and cycle time at a construction
site. The excavator actual productivity refers to the
maximum possible productivity in real construction site
conditions. The SRF includes the use of a video camera
and the analysis of recorded videos using an advanced
computer program. In cases of continuous application
of SRF, a clear and transparent base for monitoring and
control of earthworks can be obtained at an observed construction
site.
