Stockpile volume measurement is very important, especially in highway construction sites. Monitoring inventories, as well as keeping records of stockpiles, is one of the key elements in the success and optimizing the construction site works. Inventories in the case of construction sites are constantly changing; the raw material stored is on the one hand supplied by the suppliers and on the other hand transported and used on the site. Within this paper we aim to compare different methods of measuring and determining volumes. We also develop a workflow for UAV photogrammetric measurements and compare the volumes obtained with different specialized software. Using different software even on the same UAV data set, we obtained relatively similar results, the differences being due mainly to the different 3D modelling of the surfaces. To determine as precisely as possible highway construction sites, stockpile volumes the UAV photogrammetric method is the most precise in terms of the accuracy of the results obtained. This method also saves a lot of time on the site and is also risk free.
