In the process of the zero cycle construction works, significant deviations from the design solution may often occur, the legality of which can be justified by making changes to the design documentation within the framework of scientific support. The article considers an example of a new construction of a multi-level underground parking lot with a complex of buildings in the urban development and analyzes the problems encountered during construction works of the zero cycle. The condition of the construction pit and the neighboring buildings was analyzed using numerical modeling and analytical calculations. Based on the results of the analysis, there was assessed the safety of the introduced changes for the surrounding buildings. Geotechnical deformation monitoring was carried out throughout the zero cycle. When significant additional settlement of the neighboring buildings was detected, protective measures were implemented to stabilize uneven deformations. As practice shows, at many construction sites in St. Petersburg, in conditions of weak soils, scientific support of zero-cycle works is a necessary component (and in some cases - a mandatory type of work) for successful commissioning of buildings and structures of new construction.
