The article presents the results of testing bored piles with a diameter of 2 meters and a length of 55 and 65 meters during the construction of the Lakhta Center tower. The tests were carried out with a bidirectional load using lowering jacks. As a result of the tests, it was found that the resistance of the soil both along the side surface and along the lower end. The resistance along the lower end is on average no more than 10% (when moving 40 mm) of the resistance along the side surface, has a large spread and may not be taken into account in the margin of reliability when calculating. It is also found that the soil deformation modulus determined by reverse calculations based on the results of pile testing is 2...3 times higher than the values determined during standard soil tests, and the soil shear resistance calculated according to SNiP 24.13330.2016 is several times higher than the experimental values. In this regard, it is proposed to determine it taking into account the Coulomb-Mohr dependence, taking into account the over-compaction of the soil.

Currently, a new generation of IT technologies has appeared: cloud computing, intelligent computing, the Internet of things, big data, etc. Many solutions are built on the basis of the Internet, moreover, their implementation required the development of a new Internet protocol IPv6 - to expand the address of the previous version of IPv4. Some of the solutions relate to modern telecommunications: wireless communication channels, modern versions of wi-fi, wireless sensor networks. The list goes on, it is constantly updated and expanding. A number of solutions related to new IT technologies are used in the construction industry, it is necessary to comprehend the accumulated experience, others are clearly not used enough, it is necessary to assess the possibilities of their implementation. The article conducts a study of new IT technologies from the point of view of the possibility of their use in the construction industry.

Introduction: The calculation of heat loss of the room is a mandatory part of any project. Most of the information required for calculations is present in the building information model and can be extracted from it automatically. An example that requires the transformation of digital model information is the task of constructing room zones when calculating heat loss through the floor. Existing software products do not have modules that allow you to automatically calculate the heat loss of a room, including through the floor, breaking it down into zones. The object displacement functions built into the software products are not intended for constructing floor zones and cannot be used as a component of the developed module. These reasons determine the need to develop an algorithm for constructing zones that are necessary for calculating heat loss through the floor, and its implementation. Materials and methods: An algorithm for the formation of floor zones of a room is presented. The algorithm allows you to build zones for placing an arbitrary layout. Results: A plug-in for Autodesk Revit, which implements the proposed algorithm, was tested on the calculation of heat losses in the rooms of the technical floor of the building. As a result of the experiment, a reduction in the time required for the preparation of the initial information and for the calculation, from 4 hours to 2 minutes, was revealed. Conclusions: The developed software module, designed to calculate the heat loss of premises through the floor of premises, broken down into zones, is a step in the development of software products that use a digital building model as initial information.

The article proposes a method for calculating the bearing capacity of the foundation together with the soil base, where the reinforcement of the slab part of the foundation is calculated, in which the destruction by bending and punching occurs at the same ultimate load, taking into account the strength characteristics of the soil base and the non-uniformity of the contact stress diagram. For this method, calculations were carried out for various types of soils and the scope of its application was determined.

A priori, both buildings and structures under construction and in operation throughout all life cycles are subjected to various external and internal static, dynamic and other types of impacts. Wind loads play a special role and share of dynamic impacts, the force effect of which, their modules, impact lines and application points are difficult to predict. Nevertheless, such impacts obviously cause kinematic movements with complex trajectories of individual components of buildings and structures, their individual structural elements with different amplitude and frequency. The paper develops an algorithm for finding the kinematic parameters of these structural elements, their speeds and accelerations, which can subsequently be used in digital "BIM" models of buildings. Conceptually, the buildings and structures under consideration were virtually subjected to horizontal high-rise "expansion" during the study by a set of separate material points of the corresponding structural elements in the form of horizontal disks, or separate material points of a set of structural elements performing complex kinematic trajectories as a result of external influences. The algorithm uses definitions given by L. Euler, such as precession angles, nutation angles and angles of proper rotation.

Statement of the problem. The subject of the research is information models of a complete life project in the sector of architecture, design, construction and operation of buildings and structures. The purpose of the study is to build a model that implements the forecasting of the progress of the calendar plan and optimizes management decisions aimed at minimizing the negative consequences of external stochastic impacts. Results. An information model of construction based on a vector description of basic structures and hierarchical construction of derived structures is constructed. All model structures are divided into static and dynamic components. Based on the information model, optimal algorithms for monitoring the implementation of the calendar plan and optimizing management decisions in the conditions of external stochastic influences are formulated. Dynamic indexes are obtained that allow optimizing both strategic and operational management decisions. The optimal monitoring frequency in terms of the cost/return ratio has been determined. The software implementation of the algorithms proposed in the work in the shell of the relational database management system has been performed. Conclusions. The results of the study allow us to conclude that in the conditions of external stochastic impacts, information technologies significantly simplify the dynamic monitoring of the implementation of the construction schedule and the development of management decisions. The introduction of a vector description of the information model of the full life cycle into the practice of the construction industry makes it possible to optimize both local models and mechanisms of interaction between project participants.

Statement of the problem. Low-rise construction is characterized by a relatively low cost and a possibility of forming effective insulating structure shells. Frames and massive walls are used as load-bearing structures, it is also possible to use concrete. Taking into account the current realities, the most relevant is the orientation of systems to the use of domestic materials including those capable of functioning effectively in harsh climatic conditions. Results. It was established that the properties of polyethylene foam and products based on it make it possible to recommend this material both in facade and roof insulation systems as well as in those in contact with the ground. It was found out that polyethylene foam causes almost no changes in the properties under freezing conditions down to minus 70 °C and in the range of sign-variable temperatures from -60 to +70 °C. With prolonged contact with water or water-saturated soil, the properties of the material are also stable. Conclusion. The use of rolled polyethylene foam is promising both in terms of the properties of the material itself and in view of the possibility of forming seamless insulating shells. The formation of seamless insulating shells creates practically impenetrable heat-vapor- and water-insulating barriers along the perimeter of the insulated object. The study of the properties of polyethylene foam in various operating conditions and insulation systems was the goal of the research described in the article. Methods approved by domestic standards were adopted as the basis for the research.
