In the article the results of studying the experience of factories of the construction industry concluded that the production of products manufactured are loss of original building materials. The proposed method of elimination of losses and method of calculation of the amount of these losses. An algorithm is developed to determine the causes of losses, as well as recommendations on elimination of waste construction materials. The research results are recommended for practical application in the factories of the construction industry

the article presents the results of monitoring operation of a press for molding bricks. The proposed modernization of the press with the aim of eliminatingdefects of bricks. The aim of the study is the elimination of defects in the manufacture of brick. To achieve this goal it is necessary to solve the following tasks: to carry out monitoring of the press in operation; to identify the causes of defects in brick; to upgrade the press design. The research results are recommended for practical use in factories for the production of bricks.

The algorithm of determination durability parameters, loading and resource by means of analytical transition from selective data to population data is considered. The analysis of the executed calculations for this algorithm showed that receiving parameters of likelihood distribution for set on one casual sample is the confidant.
