The correct estimation of the productivity of construction machines in the construction activity is a priority, especially in times of increased competition. At the same time, it must be done in safe conditions for both workers and passers-by and residents. The innovation of the book is the unified treatment of the production process with the analysis of its influencing factors, such as the characteristics of the machine, the work method and the human factor. The productivity calculation methods are presented comparatively, in a way that demonstrates their differences and similarities but also facilitates their application. Thus, the book aspires to be a useful aid to both students and manufacturing engineers concerned with structural machinery productivity estimation, safety and cost management.
