The basis for this paper is research conducted in 2010-2014 on the construction sites of water supply and sewerage systems located in the provinces of Lower Silesia and Opole. The research consisted of direct observations of construction sites and review of construction documentation. It showed that work stoppages on the examined construction sites were frequent. They were caused by violations of work discipline by the production employees, adverse weather conditions, and defects in the project documentation. The study demonstrated that in almost every case, these bad an adverse effect on the completion date and budget of the investment. The analyses show that in such important and expensive investments as water supply and sewerage systems, organizational structures in which a special role is assigned to middle-rank personnel should be adopted.}, type={Artykuły / Articles}, title={Przyczyny oraz skutki zdarzeń niepożądanych na budowach systemów wodociągowych i kanalizacyjnych}, title={Causes and effects of adverse events during water supply and sewerage system constructions}, URL={http://www.czasopisma.pan.pl/Content/84083/mainfile.pdf}, keywords={systemy wodociągowe, systemy kanalizacyjne, przerwy w robotach budowlanych, water supply systems, sewerage systems, work stoppages}, }
