The article explores a model in which it is possible to predict the timing of obsolescence of a construction site. The purpose of the described techniques is to ensure stable operation and reliable operation of facilities. The presented methodological approaches make it possible to improve the accuracy of the assessment of degradation processes, covering both technical elements and structural parts of buildings and infrastructure systems. The article focuses on effective tools and methods used to survey the current state of real estate, as well as to anticipate changes in their performance over time. The paper considers the application of a generalized computational wear scheme that demonstrates changes in the organization and destruction of building elements throughout the service life. This scheme takes into account the continuous influence of external conditions on the structure of the structure. The universal formula proposed for the analysis serves as a research tool and displays the course of changes in the state of technical systems under the influence of prolonged loads.

For neural network algorithms to work successfully when processing 3D point clouds, it is necessary to provide a detailed point cloud of the external environment. A similar task arises when a manipulative robot is operating in a new environment, where before processing a cloud of scene points, it is necessary to obtain a detailed representation of the external environment using an RGB-D camera mounted on the end link of the robot. To solve this problem, this study proposes an algorithm for adaptive control of a manipulative robot to build a model of the external environment. By applying an adaptive approach, during the research of the external environment, the manipulative robot moves the RGB-D camera, taking into account the changes in the current environment model introduced by the previous RGB-D image. The results obtained allow us to judge the effectiveness of the proposed approach, showing that due to adaptability, it allows us to achieve high scene coverage rates.

This article examines the key features of the functional planning and architectural spatial organization of the typological group of public buildings and structures in the renovation of industrial buildings in coastal areas in order to create promising models of two different types of multifunctional spaces: creative clusters and multifunctional complexes. Both approaches take advantage of the structural and spatial advantages of these buildings while simultaneously implementing modern architectural and environmental techniques. For both types of renovation, adaptive space reuse, integration of green elements, sustainable energy solutions, increased accessibility, and preservation of industrial heritage are common methods. The specific changes for creative clusters include the transformation of the main workshops into flexible exhibition and cultural spaces, the inclusion of artistic elements and the creation of public areas. Conversely, multifunctional complexes turn these spaces into office areas, coworking areas, commercial premises and residential apartments. Overall, these renovation models not only revitalize the physical environment, but also contribute to the cultural, social and economic development of coastal urban areas, creating an incentive for future urban renewal projects.

The article presents the results of static and dynamic calculations of a 14-storey administrative building with two underground floors. The building is located in the city of Sochi. The seismicity of the construction area is 9 points. As a result of calculations under seismic influence, characteristic isofields of movements of the building system in different directions, stress isofields in load-bearing monolithic reinforced concrete floors, and force plots in core elements were obtained. According to the results of the verification calculations of the load-bearing reinforced concrete structures of the building frame, it was revealed that the strength of the individual columns of the underground floors of the building is not ensured. Options for reinforcing columns using various options are presented: classic reinforced concrete cage, metal cage, pasting with composite tapes, steel-reinforced concrete cage. As a result of comparing all reinforcement options, the most optimal reinforcement option was adopted from the point of view of technology, economic feasibility and strength parameters.

The impact of various types of loads on the integrity of the insulating shell is being evaluated and proposals are being developed to improve the operational resistance of light mineral wool slabs in the pitched roof structure. The result of the research was the development of mineral wool products with an alkali-resistant glass mesh reinforced outer layer. The operational resistance of the insulating shell increases by 1.7 times compared to light slabs based on stone wool and by 2.4 times compared to slabs made of glass wool.

The paper presents a simulation of flight control of an unmanned aerial vehicle (UAV). A distributed control system is proposed that sequentially includes internal and external circuits to control the state of motion of the aircraft. The control efficiency of a cascade PD controller (proportional-differential) is higher than that of a traditional PID controller (proportional-integral-differentiating). A new cascade control algorithm with a PD controller is proposed. First, the dynamics of the UAV is modeled based on the Newton-Euler method, then the state of motion of the device is controlled by a distributed control system based on cascaded levels of proportional derivatives of the internal and external contours. The simulation results show that the controller, developed on the basis of proportional-derivative control speed of internal and external circuits, is able to achieve fast tracking of the position and orientation of the UAV in case of external disturbances and has good control quality. The developed algorithm has increased the control efficiency by 5-7% compared to the traditional PID algorithm.

The authors of this article raise the issue of the correct selection of internal material for sandwich panels. The use of these structures is widespread in the construction of industrial facilities, so it is important to consider all the parameters of possible options for the optimal choice. The authors define the objectives of the article as the creation of an auxiliary comparative table with the parameters of the most popular thermal insulation materials for sandwich panels based on regulatory and theoretical information, as well as the formulation of recommendations for the use of a certain material depending on the specified conditions. Particular attention in the study is paid to such properties of materials as moisture resistance, flammability, durability, density and thermal insulation.

The article is devoted to the analysis and optimization of the stability of engineering structures to wind loads through the use of innovative structures of support and anchor foundations. In modern construction, when the requirements for reliability and stability of buildings have increased, special attention is being paid to the development of effective foundations capable of withstanding both compressive and pulling loads. Support and anchor foundations are presented as a comprehensive solution, including combined anchors and a monolithic slab (grillwork), ensuring uniform load distribution. The main focus is on the combined anchor, which acts as the main working element that receives the forces from the structure and effectively transfers them to the ground. Unlike traditional piles, the proposed design significantly increases the resistance to pulling due to the use of wire anchors with high load-bearing capacity.

This article presents a conceptual framework for assessing the maturity of construction control and supervision systems at construction sites. A multi-level assessment model has been developed, integrating the Analytic Hierarchy Process (AHP) and fuzzy comprehensive evaluation method. A five-level taxonomic system for grading the maturity of regulatory mechanisms in the construction industry is proposed. The procedures for forming a hierarchical structure of assessment indicators, constructing judgment matrices, determining weight coefficients, and applying the fuzzy comprehensive evaluation method to quantify the maturity level of supervision systems are described in detail. The developed methodology represents a universal tool for conducting comparative analysis of construction control and state supervision systems in various national and regional jurisdictions based on objective quantified criteria.
