This article studies modern software packages used in drawing construction master plans and their elements. A special emphasis is placed on increasing the level of design works, improving their quality, and expanding the community of technically unskilled users. The article describes approaches to solving the task of visualization of organizational and technological solutions and gives a comparative analysis thereof. It presents a visualization diagram of an organizational and technological solution for the construction of a building. It also highlights the most promising direction in graphic modeling of a construction process for buildings and structures with visualization seen as the most objective solution to address the assigned task.

Economic indicators of construction production are directly related to the choice of the optimal number of machines. The lack of machines for the production of construction and installation works leads to the impossibility of their implementation in the directive period. The pace of construction and installation work and labor productivity depend, to a large extent, on the degree of provision of construction facilities with machines (level of labor mechanization). The article considers the calculations of the need for construction machines for the building site, trust and the ministry. When determining the need for machines for construction sites, it is necessary to take into account ensuring the execution of works in the planned timeframe, increasing the level of complex mechanization, increasing labor productivity and reducing manual work, improving the use of the machine park and their operation. The article presents a consistent set of formulas that must be used when choosing construction machines and determining their number.

The article discusses several particularly significant questions related to seismic stability of steel frames. The tests produce the result of steel frame endurance under different loads, implying the condition of structure’s weakening. The paper presents the study of natural seismic noise indices fluctuations, displacement amplitude, noise decrease under various designs and implication of the dynamic loads. The issue of the impact made on the dynamic characteristic of changes are represented in the article’s sections, as well as the review of possible experimental methods of determining the endurance of the frames under seismic loads. The paper represents the empirical study of artificially damaged steel frames performance under the dynamic load, calculation of the extent of steel frame joints displacement, the degree of changes under natural and artificial seismic noise with load implication. The work aims at objective conclusion of frame performance, and states that loads and artificial damages modeling produces ineffective results for estimating the performance of frames in real/natural conditions, due to the fact that the effect made by frame’s connection nodes and the base was not taken into consideration. The paper implies further research in the area, with regard to the joint functioning of the foundation base and the frame under the dynamic load.
