Innovations' application of techniques and technologies to modern construction production, along with the reduction of manual labor, also boosts its technical and economic performance. Construction production is one of the fields in the country that plays the most important role and reflects the dynamics of the development of the economy in itself.  In our country, the issue of organizing a cheap housing market has an importance among  a number of socio-economic issues. The programmes adopted in this direction and the initiatives  dealing with the improvement of housing conditions for people from a number of categories are evident proof of this. And this, in its  turn, requires the solution of a number of organizational and technological problems of construction work carried out by monolithic reinforced concrete structures before both the designers and builders. The article explores the ways of timely commissioning of high-rise monolithic reinforced concrete buildings, improving the organization of work, and increasing the technological efficiency to reduce the cost of construction products. It was determined that during the reinforcement of monolithic reinforced concrete structures, automation of works will reduce labor costs, material consumption, product cost and construction time, while technological efficiency is increasing.

The study of the influence for design solution detailing on the cost of reinforced concrete structures during their optimization is carried out. A hypothesis is formulated on the final improvement of the target criterion with an increase in the number of variable parameters. Depending on this number, the concepts of three levels of detail are introduced, at which optimization can be carried out, and the degree of risk of failure of the structure is indicated for them. Using the example of finding a constructive solution for a reinforced concrete beam by the cost minimization criterion, the relationship of the cost change is shown when the number of independently variable parameters changes. The normal operation of the beam and the emergency action effects in the form of local damage to a single corner connection are taken into account. Genetic algorithms are used for the optimization.


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.
