In modern construction production, the volume of management, technical, economic and legal information has increased significantly. This increase relates to the design of buildings and structures, to the documentation of construction processes, as well as to the obtaining of permits and the assessment of compliance with the requirements of technical regulations. The reason for this growth is the widespread use of digital technologies by design, construction, regulatory and Supervisory organizations. The purpose of the work is to systematize and synchronize the documentary support with the stages of the life cycle of capital construction projects from the initiation of the capital investment project to the commissioning of the capital construction project. As a result of the formalization of the system-forming principles of documentary support for each stage of the life cycle of the capital construction project, the problems of documenting the construction industry are formulated: first, the need to automate the filling of standard forms of primary accounting and reporting, second, the improvement of information transfer and storage technologies, third, ensuring reliable protection of information that describes the processes of construction of buildings and structures. These problems should be solved in accordance with the national legislation of urban planning, approved standards of technical regulation and the current regulations for the technical safety of buildings and structures.

The methods of the diagnostics and oil-and-gas installations state analysis reliability increasing based on usage of the parametric methods of statistics are discussed in this paper. The variance analysis of the mechanical properties of the pump rods made of normalized steel is given in this paper (according to the data of the manufacturing plant for the period of 10 years). It is found that breaking point and yield stress are distributed with the truncated normal laws in the region of minimum values. The obtained average values and variation coefficients of the mechanical properties within the steel grade permit to calculate the statistically significant changes of the mechanical characteristics. The correlations between Vickers hardness and breaking point (Vickers hardness and yield stress) in the case of steels produced in the Russian Federation for the pressure-operated vessels are also presented in this paper. These correlations permit to determine the strength characteristics with the relative error of 12% according to the hardness value. In the case of transferring the obtained correlations on the steels produced in Japan the systematic underestimation of the yield stress is 0,85 fold with respect to the value given in the certificate. The factors that influence on the microanalysis sensitivity and accuracy are revealed, the optimal scanning electron microscope mode and research conditions for the chosen patterns are also determined. Evaluation of the systematic inaccuracy of determining the carbon content in the steel is obtained in this paper. It is found that the measurement error for the scan area from 3 x 3 to 20 x 20 mm and accelerating voltage from 10 to 15 kv is minimal. The usage of the obtained results permits to increase the validity of the findings in the diagnosed installations condition evaluation and determining the conditions of their further exploitation.

In the article presents an analysis of changes in the flow of failures of trucks with diesel and methane-diesel engines. As a result of analysis revealed a change in the reliability of diesel cars converted to work on compressed natural gas. This led to a change in their effective operation because of the increased amount of downtime to repair. Another reason of the decline in effective work vehicles - reduction the carrying capacity, because of the need to transportation a extra weight in the form of compressed gas cylinders.
