The problems considered within the frame of scientific and technical support are shown on the example of design and construction of a unique high-rise building of "Lakhta Center" in St. Petersburg. The main results of design support and construction of steel, steel-reinforced concrete structures, as well as structures made of laminated glass are presented. The main reason for atypical design and technological solutions for steel structures are thickness of rolled steel and the material of structures non-standard for domestic practice. In addition, there was no normative approach to the design of steel-reinforced concrete structures and structures made of laminated glass at the time of design of the complex. The tests carried out within the scientific and technical support provided the necessary information for the design of unique structures. It is required to develop the set of rules defining the requirements for scientific research when constructing unique objects for a more orderly scientific and technical support and justification of the amount of work performed.
