Abstract: A large number of reinforced concrete structures in early stage of life show symptoms of deterioration which are consequences of mistakes in design documentation, or based on poor execution. Problems of structure durability and quality insurance by proper recognition of the environmental conditions in which the structure is placed in are often treated with lack of attention and mostly craftmenshiply, with insufficient data in design documentation. It is especially visible in problems of design and thickness definition for coating layer, curing conditions and maintenance. In the paper are given some of typical damages caused by wrong presumed environmental conditions, incorrect material selection for structure execution or insufficiently elaborated quality requirements in technical description, bill of quantities etc. By that mean, after analyzing location conditions and possible harmful actions on the observed structure, possible repair techniques are shown due to minimize costs and optimize results required for usage as it is designed. In some cases mistakes by improper environmental conditions assumptions are visible after a certain period of time, when structure is in use, which causes more problems in repairment process, and, in addition, larger expenses and inability of structure usage due to its prior design.
