Automated Project Performance Control (APPC) of Construction Resources

ABSRACT: Real-time control of on-site construction is a growing field still in its infancy. A model for automated control was developed, implemented and validated in the field, to verify if Project Performance Indicators (PPI) can be automatically measured and controlled. The concept behind this development is that indirect data – locations measured automatically at regular time intervals – can be collected automatically and converted into PPI using computerized algorithms. The model was implemented in a concept-proving prototype for productivity measurement. The prototype was tested in four construction projects – three buildings, and one road – to validate the concept and test the feasibility of developing a full-scale prototype. The encouraging results of the field experiments confirmed that it is possible to convert the locations, automatically measured at regular time intervals, into productivity, and thus automatically control them. The expected accuracy of such a system is ±10-20% for building construction and ± 4-5% in road construction.
