Disturbance Analysis and Their Impact On Delays in Construction Process

Despite the development of: modern technologies, the software supporting the management of construction projects, popularizing of the tools for data analysis and numerous studies on factors interfering the efficient course of the construction process, the delays are still a phenomenon often present in the construction industry. Based on the literature, it should be noted that the main goal of the researchers is to try to rank the factors causing delays in the construction and their classification into groups. Frequently, the classification criterion is the participant’s status in the investment process (a designer, a contractor, an investor, etc.); the general macro division into factors related to an investor/a company, a contract, the external environment or the division by resources, i.e. human factors, hardware factors and material factors. The subject of investigations of the authors of this article is to identify the types of disturbances causing delays and their classification depending on the scale and degree of influence on the further implementation of construction processes based on the implementation of a commercial and service building. Analysing the course of the implementation of the construction project, it is possible to indicate those factors that cause the necessity to engage considerable resources and change the sequence of processes to minimize the delay. Therefore, it is important to monitor the processes and control of work progress indicators, enabling early detection of delays and planning alternative solutions.
