The article examines architectural approaches to the design of temporary museums and exhibition pavilions. Particular attention is paid to the concept of modularity as a tool for spatial adaptation and rapid installation, as well as mobility as a strategy for expanding cultural presence beyond stationary institutions. Historical and contemporary examples are analyzed, including so-called pop-up museums, container galleries, and disassemblable exhibition modules. The role of innovative materials, digital design, and transport logistics in the formation of a flexible architectural environment is emphasized. The article reveals the potential of temporary exhibition structures as a tool for social inclusion, urban renewal and cultural decentralization. Special attention is paid to Russian and international experience. The modular museum is presented as a type of architecture sensitive to time, place and cultural context.

The article is dedicated to analyzing the changes in museum design in the context of the rapid integration of digital technologies. It examines the ways of integrating multimedia systems, virtual and augmented reality into the architectural structure of museum spaces. Based on the analysis of domestic and foreign examples, new approaches to exhibition formation are identified, built on principles of flexibility, interactivity, and immersiveness. The emphasis is placed on the changes in typological models of museums: from traditionally hierarchical to adaptive, transformable formats. Special attention is given to the evolving role of the architect, acting as a mediator between digital scenarios and spatial expression. As a result, the museum of the future is envisioned as a complex spatial-technological ecosystem, in which architecture becomes an active participant in communication with visitors through digital content and technological interfaces.

The article presents a study of the hydrophysical properties of modified cement concretes, namely frost resistance and water resistance. The compositions of modified concretes for research are determined. It is established that the use of mineral fertilizer production waste in combination with the superplasticizer "Osnovit Safescreen SPP1" allows to increase the frost resistance, water resistance and strength of concrete composites.

The paper reveals the problem and causes of the formation of fetid compounds in the systems of transportation and wastewater treatment. Various methods used at the moment to eliminate and neutralize unpleasant odors, as well as a number of measures to clean the air from fetid compounds are considered. A new method is described to prevent the formation of odors of fetid compounds in wastewater transportation and treatment systems and a device for its implementation using low-intensity cavitation. The scheme of the device for sewage treatment from smells of fetid compounds. The principle of operation of this installation is described.

The article substantiates the expediency of classification of technical heat-saving methods in the operation of residential and public buildings. The results of the study of the physical nature, efficiency and rational application of these methods were used in the classification according to their main function. The proposed classification of heat-saving methods is recommended for use in the integrated assessment of heat efficiency of residential and public buildings, and in determination of sources of heat savings during their operation.

The simulation of the magnetic field distribution in magnetic conductors of electrotechnical devices for the purpose of assessment of their characteristics in the operation modes is considered. The task has a form of the boundary value problem for the elliptic type equation in the ferromagnetic environment with nonlinear characteristics. We suggest using block elements in the form of arbitrary configured multipolar networks in the combination with nonlinear multangulars. The veber-ampere characteristics of the multipolar network are the result of a single solution of the boundary value problems for the multangulars forming block elements. The boundary value problems are solved using a complex finite element method, which provides direct solution for equations of constraints between magnetic strains and multipole fluxes. The nonlinearity of the characteristics is taken into account as a result of calculating the field distribution at the boundary of the multipoles by correcting the magnetic permeabilities of the block elements, which is performed iteratively.

The article describes the main principles of the movement around the circumference of the cranes circular steps. It is proved that the defining characteristics of the organization of the movement of the crane on the circle are the geometric parameters of the mutual reversal of the running wheels of the crane, not the observance of the reversal determines the transverse slippage of wheels of the crane, and the shape of the wheels depends only on the elastic longitudinal slide. The result of slides and slippage is firing the head of the rail with one hand and the loss of stability when moving the crane. Stability stability ensures the achievement of the precision targeting of the gripping device. These parameters are the main performance characteristics that should be valued in absolute terms should be minimal.

the article presents the study in the control of the geometric parameters of wheels of cranes circular steps. The options considered to determine the radii of the wheels by indirect methods, of which the most effective are those based on the construction of the measuring triangle at the open part of the forming. As the final results and proposals noted the following: both control provide almost ravnovesnye results definitions of the geometric parameters of the wheels; more universal is the way to control the radius of the wheel, using calipers and this method is recommended when addressing these and similar problems.

the Basic meaning of the content of the article is to reveal the formation of professional competence of students of higher education construction professions on the example of a business game. Business game "facade" is the functional-architectural meeting ambitious designers" was held under the second course in the discipline "Construction materials". The essence of this method is that students demonstrate certain production situation, which is characterized by conditions and actions of its participants. The task is to find the best modern methods of construction technologies. As a rule, the production situation in construction occur on the object, in our game object – the building of the Palace of culture, which was commissioned 10 years ago. During the operation of the building facade cladding in some places, damaged, cracks, and loose tiles. It was necessary to find the right solution for the replacement of the cladding material, to previously conduct a survey and identify the cause of the damage. For this group of students was divided into subgroups and each defined role. Each of the groups in the course of a game functioned, however, all must understand by simulating the situation and content of the actions of other groups. The problem was the following, as a preliminary survey of the damage to the facade of the object (performed measurements, photos, samples provided to the facing surfaces of the facade), it was necessary to establish the cause of the damage and propose the most optimal, effective and meets all the architectural, technological, technical and economic requirements methods of eliminating damage.the new enterprises, redistribution of investments in interests of the organization and development of new production on available floor spaces. The most important organizational economic targets of a diversification of management are presented by innovative activity of the industrial enterprise.
