Over time reinforced concrete construction tend to lose their strength properties. An important factor in maintaining the integrity of reinforced concrete structures is the compliance of the parameters of the erected structure with its design values and operating conditions. Otherwise, the likelihood of defects such as the formation of cracks in the protective layer and corrosion of reinforcement increases. There are methods for restoring reinforced concrete structures that can return the strength characteristics to the design level or even exceed it.

Organizational and technological installation operations for flat arches and window boards in the window openings of brick buildings are developed based on innovative modern buildings, on economically justified methods of work production. It is proposed domestic technical rigging, tools, means of performed works quality control taking into account the solution of import substitution problem while works production. Regions of the Russian Federation having clay and sand as local materials for bricks production prefer to use the bricks in low-rise buildings construction. It is emphasized a need to resume the use of standard projects for construction of residential low-rise buildings, cultural, recreational, educational, sports, medical and commercial buildings made of brick as a local building material. One gives the algorithm of the construction process: storage on construction site, workplace supply and erection (installation) of flat arches and window boards in window openings of brick walls. The article describes in detail construction process organizational and technological solutions and techniques. General instructions on the safety of work, as well as the organization and methods of workers labor are given. The possibility of construction time reducing by typifying the low-rise buildings construction, including those made of bricks, using locally available construction materials is shown. The article shows the efficiency of use of labor resources and construction materials supply from storage site to installation spot, considering the correct assembled elements installation provision.
