Abstract
This authors propose an algorithm for estimating the operation reliability of complexes, sets and separate machines using statistical information based on the results od full-scale tests or modeling of their operation by Monte Carlo`s method. With this method it is possible to form a sample and calculate the basic parameters of the samples of construction machinery’s operation on any object. This will allow predicting for certain the period of construction and installation works at the design stage of construction. The authors determine the indicators of organizational and technological reliability of machines, standard of time, performance and cost of developing 1000 m3 of soil, as well as hours of operation, shutdowns and technological stops of excavator sets per shift. Keywords: organizational and technological reliability, organizational and technological risk, performance, excavator set, construction machines.

Abstract
The authors analyze probabilistic models of a static component of wind load and compare the calculated values obtained for each of the models with different "urgent" probability. The authors conclude that the probability of wind load’s normative values of the limiting state’s method corresponds to 5 - year period, and the calculated values - to 50 - year old. There are presented tables with the calculated values of wind load for all wind areas that are handy in designing high buildings.

Abstract
The authors present a design scheme of a bridge crane and also its simulation model. A regression model, which allows determining various parameters of the brifge crane’s working process, is built on the basis of the simulation model. It is concluded that the complexity of the regression expression by increasing the number of its items beyond 12 doesn’t lead to further increasing the accuracy of approximation.
