In this paper, the un-controllability of construction labour, which is a basic factor in construction management is analyzed. This study is based on a field survey in a site of public housing project that has about one thousand collective dwelling units with the same plan and spesification. The object of the investigation is the prefablicated interior work, in which the work load and schedule time of the carpenters crews were fixed ahead. The investigation's summary results are as follow : 1. Each crew's way of work-dividing is different from the other. 2. Each crew's operation arrangement methods, and the sequence are different from the other. 3. The average amount of man-hours per unit of each crew varies and differs up to 1. 7 times. We can say that there is no same operation way in the sitework. In other words, each crew has its own operating method. As there is not much difference in the object and condition of the operation, we must consider that the difference depends on subjective factors, especially worker's skill. In short, skilled worker has autonomous control on his work, so that the controllability from the outside is comparatively in low level. It comes as the result of worker's self-adaptation to the various conditions of construction projects. Therefore, in the light of the above findings, we must consider the method of construction control in respect of the skilled worker's autonomous control ability.
