Engineering-geological conditions of St. Petersburg, which are characterized by a large thickness of soft water-saturated lake-glacial deposits, are presented. The main characteristics of soils and examples of static sensing results are given. There are considered the main technical characteristics of the foundations of the compound "Lakhta-Center", including a 462-m-hight skyscraper - the tallest building in Europe and a multifunctional center of 85 to 15 m. The main technical characteristics of the foundations of the unique Gazprom-Arena football stadium with an opening roof and a retractable field are presented. Engineering-geological conditions of St. Petersburg, which are characterized by a large thickness of soft water-saturated lake-glacial deposits, are presented. There are considered the main technical characteristics of the foundations of the compound "Lakhta-Center", including a 462-m-hight skyscraper - the tallest building in Europe and a multifunctional center of 85 to 15 m. Saint Petersburg is the northernmost city in the world which has the population over one million people. The lake-glacial deposits - clays, loams and sandy loams - are practically pervasive and have the stratified or ribbon structure. Within the city area, primary deposits are represented by Proterozoic, Paleozoic and Ordovician deposits covered by Quaternary sediments. A space between three slabs of the box foundation is formed by underground floors, in the center of which a reinforced concrete core of the skyscraper is located with 10 radial walls going from it to the external perimeter.
