Delays in construction works in Polish construction industry from the contractors’ point of view

Abstract

The construction industry is sensitive to changing random conditions that determine the occurrence of various disturbances during the construction investment process. These disturbances are the source of numerous delays during realization of the construction project. The identification of the reasons for delays and their impact on the progress of construction works allows for the efficient management of the construction project and planning of protective measures, which reduce the risk of their occurrence. The purpose of this article is to identify and then to assess, on the basis of the conducted questionnaire survey, the impact of disturbances on delays in construction works. In addition, the factors were ranked in terms of the degree of impact on the construction project by calculating the rank of the factor.
