“…For the purpose of compliance with regulatory requirements with regard to foundation strength and deformation in conditions of fairly thick layers of loose, water-saturated soils, the project resorted to a common method for pre-construction compaction of loose soils with ballasting embankment using vertical geodrains [1][2][3][4][5][6][7].…”

The article presents the practical experience of pre-construction compaction of loose water-saturated clay foundation soils during the construction of Paradnaya Embankment in Kaliningrad. The engineering and geological conditions of the embankment construction site were complicated by the occurrence of a significant thickness (up to 15 m) of highly compressible flowing silts from the surface. The base preparation was carried out by preliminary compaction of loose soils with the ballasting embankment using vertical geodrains. The geotechnical monitoring system at the site was implemented after the construction of the ballasting embankment, in connection with which the designers made a premature conclusion that 90% of the degree of consolidation of soft soils according to the readings of pore pressure sensors was reached only 2 months after the filling of the ballasting embankment. The authors of the article analyzed the calculation methods of the consolidation process used in the design and the results of geotechnical monitoring. A repeated prediction of deformations of the soil mass from its compaction by the ballasting embankment was performed by a numerical method, taking into account the nature of the transfer of the load to the foundation, as well as the presence of shore protection structures of the embankment. A non-standard method was used to assess the total settlement of the ballasting embankment and the degree of consolidation of the foundation in the absence of correct monitoring data, which consists in determining the top elevations of loose soils by drilling control observation wells and comparing them with the results of engineering and geological surveys performed before the start of construction.

“…Tolmachev [1] plays a significant role as budget regulation. The state nature of pricing has been a priority in our country for more than two centuries, and considerable practical experience has been accumulated in this area, both in development methodology [2,3] and in application of estimate norms [4]. At the current stage pricing has serious problems connected both with standards and methodology of forming the cost of work at the stage of architectural and construction design.…”

The article presents the results of the analysis of the problems of regional investment in terms of determining the volume of investment costs in capital construction projects. The purpose of the study is to determine the relationship of the state's pricing policy in the construction industry to the process of allocating investments for the construction of infrastructure facilities in the regional context. The signs of uneven possibilities of budgets of different regions are highlighted. Pricing factors for construction products, in particular, due to the regulatory framework, are identified as local reasons for differences in capabilities. The types of construction objects with characteristic qualities for carrying out such an analysis are determined. Research methods are based on a piecemeal comparison of linear models of direct costs and cost conversion indices in territorial standards. Differentiation of state pricing standards is considered on the example of special types of work in the construction of urban infrastructure facilities. The estimation of the difference in the cost indicators of territorial standards is used in the assessment of the investment potential of the region. The results obtained show a multiple difference in the cost of construction resources in neighboring regions without proper justification. This makes it possible to determine the volume and cost parameters of construction projects, the creation of which is possible within the framework of the current regional budget. The proposed three-dimensional model of the timing, cost and risks of the project provides grounds for calculating the qualitative indicator when choosing objects of investment programs of the regions. It is concluded that there is a need to move from a system of loosely interconnected territorial and sectoral budget and regulatory bases to a unified information environment.
