The diploma paper deals with the analysis of productive, unproductive and additional time by the final felling and production of conifers. On a chosen intersection in Pokljuka a study of time was made and a work process of a forest worker was being recorded for ten days. Field conditions were being estimated and daily effects on the forest worker were being measured. The reasons for differences between the recorded and calculated time were being assessed and analysed with regard to standard times. The recording took place in two separate working fields, but they were not different enough to show that the change in field essentially contributed to the share of productive and unproductive time. The share of productive time was 61, 26 %, while the share od unproductive time was 38,74%. The forest worker cut 224 m3 of conifers in 10 days, on average therefore 22,4 m3 daily. It also overfulfilledthe daily norm for more than 100%, mostly on account of very thick trees and spent 15, 82 minutes on a m3. We proved that there are huge differences between state standard times and the actual effects by felling andprosessing.
