The article compares the indicators of experimental and calculated bearing capacity of bored piles installed using DDS technology, according to static tests and normative calculations. The article also presents results of compression tests of soil samples around the placed piles using the Drilled Displacement System (DDS) method. The authors established dependence of the deformation properties of the soil, such as the modulus of deformation, the angle of internal friction and adhesion, on the diameter of the bored pile. The coefficient of working conditions of the soil of the lateral surface of bored piles installed using DDS technology is obtained based on the results of numerical modeling of bored piles located according to the traditional and proposed DDS method. The article describes the innovative DDS technology, explanations of the operation of the drilling auger during drilling and displacement of soil, and in general, the advantages of the above-mentioned technology and its economic efficiency.

As a result of the increasing need to study the choice of the assigned value during the inter-laboratory comparisons is becoming more and more relevant. Since the assigned value is a reference point when comparing the results of the participants of the qualification test. Frequently, qualification verification providers face a number of problems when choosing the assigned value. An incomplete analysis of the results of interlaboratory comparisons will lead to an inaccurate assessment of the competence of the laboratory, which contributes to the revocation of the certification of the accreditation of the laboratory participant. This article attempts to provide a complete statistical analysis of the results of interlaboratory comparisons from the beginning to the end of the tour with the content of all statistical analyses recommended in GOST ISO/IEC 17043-2013. The results of interlaboratory comparisons conducted in testing laboratories of Kazakhstan aimed at ensuring metrological traceability of pH measurements in a buffer solution are presented. The reference values of the buffer solution are determined in the state scientific metrological center.

In the L.N. Gumilyov Eurasian National University, there was discovered the “Concept of a digital ecosystem for 2021–2025”, according to which the digitalization and optimization of the University’s business processes in all areas of activity were carried out in stages. According to the identification of all senses, coming in a single “Smart.ENU” package for seamless data exchange between information studies. The article describes the methodology for developing digital services of the University, based on the mobile application "Smart.ENU". Formal methods of modeling information systems, building UML diagrams, prototyping, and conceptual and logical modeling of business processes are used as research methods. The Smart.ENU mobile application is intended for students, teaching staff, received and structural divisions of the University. The uniqueness of the application includes the most complete functionality, but without duplicating the functions of the Learning Management System.

In modern architecture, there is an increased need to design constructions in conditions of dense development. It is important to implement a project without hitches. However, during the construction process, design flaws or environmental impacts can often arise in the end result. Therefore, proper design and monitoring allow taking preventive measures that helps to avoid overhaul of buildings in the future, which also affects to the cost of project, and sometimes-human casualties. During and after the construction of high-rise permanent structures often-unacceptable cracking can occur in the external walls and at the base slab of the basement. Respectively, groundwater starts to leak through the cracks of basement, compromising the serviceability and durability of the basement and rendering it unusable. The paper presents the use of fiber-optic sensor technologies geotechnical engineering. In this paper, it has been established the possibility of foundation monitoring system using fiber optic sensors during the construction process. The monitoring system includes a distributed fiber-optic voltage measurement system using a fiber-optic cable, which allows you to control deformations that occur on the surface of the plate. This study involves an investigation of the foundation system in a high-rise buildings and structures in Nur-Sultan city.

The article is devoted to the definition of promising excavator designs. The paper presents current models of excavators operating on the territory of the Republic of Kazakhstan. The main technical characteristics of the machines are considered. Statistical analysis and processing in the software environment were carried out. Summary statistics for each of the selected data variables are provided. It includes measures of central tendency, measures of variability and measures of form. Based on the correlation matrix of indicators, it was revealed that the weight of the excavator has the greatest relationship with the digging depth, its capacity and bucket volume. Cluster analysis was carried out using the software package. As a result of cluster analysis, it was determined that the existing excavator designs can be divided into three groups. Histograms of the distribution are constructed. With their help, modal intervals and the middle are determined. The criterion of significance and the weighting coefficient for each indicator are determined. The coefficient of the technical level is calculated. Based on the results of the technical level, promising indicators of power values, digging depth, bucket volume and excavator weight are proposed.

Historical structures are part of the heritage humankind hands down to posterity. As records, they not only describe past construction technologies, but they also carry information about the social system and culture of their time. Many historical civil engineering structures constructed during and after the Edo era still remain in Japan. Some of these structures, such as the Yokosuka dry docks, played an important role in the fate of the nation (Shogaki, 2014). However, such sites have not been the subject of systematic geotechnical research or publicity. The strength of construction materials at historical sites built since the Meiji era was investigated using the rebound hammer test (JGS 2013) and evaluated with regard to construction age, facility use, and material. The tested materials were rocks (andesite, granite, and sandstone) at 10 sites, concrete at 6, and brick at 3.
