The article deals with the integration of a three-dimensional model of a parametric architecture object created by Autodesk Revit and its finite element model. The features of IFC formatting expand the possibilities of presenting design data for solving problems of integration information and computational models. The advantages and disadvantages of this approach to the modeling of unique high-rise buildings, the architectural solution of which is a complex geometric surface, are illustrated. The resulting finite element models allowed us to perform a static calculation and analyze the characteristic movements of the frame elements of a unique building. The practical significance of the presented research results lies in the possibility of using a parametric architecture for designing objects using BIM with subsequent analysis of the stress-strain state of the frame of a building or structure.

Soviet industrial heritage is huge. Nowadays with latest growing of industrial sector in country, material base including architecture became very necessary. More and more buildings are reconstructed to new industries or just updating for new requirements for existing technological processes and production. Mostly reconstruction of existing industrial buildings is covering facade with facade systems without any aesthetic conceptual component which creates a problem for city reconstructed facade situated on. The article includes 7 conceptual models of aesphetical forming of industrial building's facade.

The problem of transmitting an image in a transmitter-receiver system over a noisy data transmission channel in JPEG 2000 and JPWL format under conditions of a previously unknown and varying intensity of noise is considered. This task is considered for the conditions of the IP network. The article aims to build methods for estimating the intensity of noise by the JPWL decoding results in the receiver and dynamically adapting the parameters of the JPWL transmitter to the current assessment of the noise intensity, ensuring the highest quality of the decoded image with the shortest length of the transmitted encoded stream. An experimental study of the relationship between the parameters of JPWL, the intensity of noise and the quality of the decoded image was carried out. It is shown that for any JPWL parameter there is a region of one-to-one correspondence between the percentage of fully recovered tiles and the probability of losing a network packet. A technique for estimating the intensity of noise by the decoding results of a single image is described. This technique can be expanded to use the results of decoding a series of images.

This article discusses the development of measures for the protection of atmospheric air during the construction industry. Particular attention is paid to the development and implementation of MPE projects and their implementation in the construction process. Also an important factor for environmental protection, including atmospheric air is the calculation of the radius of action of the sanitary protection zone of each construction site, depending on the sources of pollution. Particular attention is paid to the allocation of fine dust on the construction site, as well as measures to reduce these emissions. The article presents the results of the implementation of certain technological and organizational measures to reduce the release of PM10 and PM2. 5 fine dust particles on one of the construction sites of Rostov-on-don.

The paper deals with the study of the dynamic characteristics of the coating farm. Due to the changes in the company's technological regulations, it became necessary to install additional ventilation equipment with its output to the roof of the shop. The study showed that to ensure safe operation in the structural scheme of bearing structures it is necessary to organize additional units. Dynamic load on the supporting structures is created by the operation of ventilation equipment. The spectrum of natural oscillation frequencies is determined. The values of these frequencies were compared with the frequency of forced oscillations of the fans. Graphs of the changes in natural frequencies when the fan operating frequency. According to the chart, when the frequency of the driving force coincides with the frequency of natural oscillations, the inertia forces increase sharply, which indicates the passage of the resonance zone. A study of changes in dynamic forces due to rotor imbalance was conducted. The value of the gap arising at wear of bearings at which there will be a destruction of a basic element of a farm was calculated.

The article is devoted to the issue of improving the environmental safety of the construction industry by improving dust collectors of dust removal systems for the aspiration schemes of the construction industry/ It was proposed use additive-integrated dispersive analysis of variance of dust particles emissions throw out into the atmosphere by aspiration systems. The article proposes the improvement of complex analysis of variance using hydrodynamic criteria in output functions. Modified output data and additive-simplex allows getting approach to evaluate characteristics - equivalent sizes and speeds of sedimentation-soiling of dust particles with a higher degree of accuracy of the results. It makes possibility to determine the ranges of size’s and velocities’ changes with real ability. It is possible to obtain more reliable data of sedimentation rates and equivalent particle sizes for the studied dust samples of building materials using the distributions of the hydrodynamics criteria. Analytical approach to determining the density’ distribution of the numerical values of the hydrodynamics criteria in the output function allowed us to clarify the more real values of sedimentation rates and the equivalent particle sizes and the range of their changes both. This way analysis of variance of dispersed dust particles could call additive-complex or simplex approach. The obtained regressions in processing the research results were used in the development of devices for capturing dust of dispersed building materials from emissions. This way could significantly reduced dust leakage out from aspiration collectors of decreasing dust systems while purifying emissions at the building enterprises. This approach is one of the most effective ways to improve the environmental safety of the building industry.
