ABSTRACT
Underground space development has become an indispensable part of the present-day construction and reconstruction projects. Being time- and labour-consuming, the installation of sites under reconstruction with multi-purpose subsurface structures and new basements involves a certain amount of risk. The article deals with engineering of an underground space in a basementless historic building. Through a series of zero-defect methods and operations, the building was installed with a 3-meter deep basement. This article presents field data and design solutions.
