| Summary: | The construction industry of Ukraine has a number of problems and barriers that hinder its development. The main problems affecting Ukraine are corruption, high level of opacity, inefficient use of resources and inefficient process management. Moreover, ineffective design and construction management reduce labor productivity and leads to reworks. Unfortunately, in Ukrainian construction industry most cases of rework have been accepted as a part of construction activities. Rework is one of the main factors in the growth of total costs and the excess of the schedule for the construction project. The problem of rework costs is important and needs to be studied more to alleviate these overruns in the future. However, rework data are usually quite difficult to obtain and most studies have been conducted in developed countries. It can be assumed that there is a greater probability of reworks and rework costs in developing countries than in the developed ones. Thus, the purpose of this article was to determine and systematize reworks factors, quantify amount of direct rework costs, determine the relationship between actual project costs, project duration variation and rework costs.
