“…Yet another is the use of the composite solutions with the addition of waste, boehmite, formed in hydrogen produced from aluminum to establish "wall in soil" and to prevent its horizontal shift, and to effectively strengthen the bases of existing buildings standing on water-saturated soils (Panfilova, 2020).…”

According to the General Plan of the city's perspective development, it is planned to develop the territories of the irrigation fields and the adjoining dam. The article details the engineering tasks of erecting the foundation-basement construction of underground structures considering the geological and hydrogeological conditions of the low-lying area of the Odessa region. Features of occurrence and genesis of low-lying part sites have been elaborated. The paper also elucidates the methods of orientation employed and water lowering during the erection of underground structures. Technological order of work execution for reliable and effective structural scheme of underground structures in water-saturated soils is proposed. A device for vertical waterproofing of external walls and horizontal waterproofing of the floor of an underground structure has been developed.

“…The construction of such facilities is frequently implemented using unprecedented design solutions, new materials that have no standard or design strength and deformation characteristics; new design methods, as well as pre-fabrication and construction requirements [8][9][10][11][12][13]; and new construction methods and techniques. In this study, structures having such characteristics will be addressed as "sophisticated construction facilities", and works [14,15] focus on the difficulties arising during their construction.…”

A New Direction of Professional Activity of Consulting Engineers in the Construction Industry

Today, the professional activities of consulting engineers need new functions based on a research-based approach to the design, construction and operation of sophisticated construction projects. The authors introduce new terms and use the concept of technology platforms to present a research-driven platform for consulting engineers. This platform is a complex system that has three constituent subsystems, including “Processes”, the “Database of work items” and “Participants”. Formalized interaction between the platform constituents is based on a tree of goals. The implementation of actions, focused on each goal, allowed (1) clustering the requirements applicable to the new type of consulting engineers; (2) developing an algorithm that underlies the database of work items to be performed by new consulting engineers; (3) developing the principle of automated selection of work items; (4) making a graphical representation of activities, performed by consulting engineers in the form of a BPMN diagram. The platform is a concept for a novel approach to the activities of consulting engineers, who will contribute their experience and use the research-driven approach to ensure the reliability and safety of sophisticated construction projects.

“…Ensuring the operational suitability of buildings on structurally unstable soils can be carried out in the following main areas: full or partial elimination of uneven deformations of the base caused by the special properties of structurally unstable soils, by improving the characteristics of the base soils [6][7][8][9][10][11][12][13] or the use of deep foundations [14,15]. In this case, the operating conditions of buildings are practically no different from ordinary engineering and geological conditions; strengthening the supporting structures of the building based on the joint calculation of the <building -foundation -deformable base= system, which allows to effectively use the strength and rigidity of the supporting structures to absorb additional forces caused by uneven deformations of the base [16][17][18][19][20][21].…”

The article considers the reduction of uneven deformations of the base of the foundations of a five-story building, caused by local subsidence of the soil, through the use of strip self-adjusting foundations. The dependences of settlement, subsidence and stiffness coefficient of the self-adjusting foundation base on the load acting on it were obtained. Using the obtained dependences, numerical studies of the interaction of a building with a non-uniformly deformed subsidence base were performed. The results obtained showed the effectiveness of the use of self-adjusting foundations to reduce uneven deformations of the base and ensure the operational suitability of frameless buildings on subsiding soils. The uneven deformation of the base under the given conditions was reduced by about two times due to an increase in the penetration of the foundation into the ground. At the same time, the maximum shear stresses in the walls of the building decreased by about 30%.
