Abstract

In this paper, the author provides provisions and definitions of the life cycle of buildings and structures. The life cycle is conventionally divided into five stages (the stage of the origin of the idea and scientific research, the formation of the design resource of constructive safety, the stage of construction (construction), the establishment of the initial (starting) resource of constructive safety, the stage of operation and its stages, the stage of technical inspection, reconstruction, strengthening and recovery, recycling stage and environmental aspects), definitions of each stage are given and conventional boundaries of each stage are proposed. In the world around us everything alive or not alive have its oven beginning and ending. The period between ending and beginning we can name as the period of existence or the period of life. We can use this abstract-philosophic statement about life period for all buildings and structures people has ever made. Some of buildings and structures made by humanity existed by ages and centuries, but other ones existed not for a long time and can disappeared from the face of the earth under the influence of set of outside and inside destructive factors.
