Construction work in the conditions of existing health facilities requires compliance with increased requirements, which imposes additional restrictions on the application of known organizational and technological solutions, which in turn create a need to develop new or improve existing methods of organizational and technological design in the reconstruction of health facilities. In the development of organizational and technological documentation, it is necessary to take into account the fact that medical facilities are not classified as production facilities, although the restrictions for this type of facilities are very significant. The aim of the work is to improve the accuracy of calculations when planning the finishing (plaster) work in terms of labor costs. As a result of the study, based on the initial data, factors describing the limited workplace were identified, which will allow in subsequent studies to justify an increase in labor costs (reduced productivity) for working conditions in a limited space during the reconstruction of health facilities.
