Tobolsk is a unique town-monument in the open air. Cultural heritage and historical sites are currently undergoing work for conservation and restorative renovation. “Station hospital” is one of the historical and cultural landmarks, which is situated in the “upper” part of the town. It was built at the end of 18th century – the early 19th century. This paper shows results of “Station hospital” basement floor computational modeling applying the program PLAXIS with regard to step-by-step work. The paper presents descriptions on construction of the basement, including soil densification of strip foundation by injection piles, step-by-step soil excavation and erection of insitu reinforced concrete caisson and basement deck. The authors examined building construction and monitored the procedure. This method of basement floor building excluded additory deformation of the structure and can be applied in analogous conditions.
