The article presents an evaluation of geotechnical state on the project construction site and an evaluation of deep excavation impact on the current site development. It also provides an optimal design for the deep excavation, an impact analysis of horizontal shifts in the shoring of excavation, an assessment of bending moments in the shoring and the forces in thebracing structures. The numerical modeling was carried out for developing variants of the deep excavation as well as a preliminary assessment of the impact that the projectedunderground structure produces on the surrounding buildings and constructions. Some recommendations on choosing a reliable variant of the undergroundstructural arrangement and the engineering operational technology are suggested.
