Abstracts: Most building defects are avoidable. They occur in general, not through a lack of basic knowledge but by non-application or misapplication of it. Knowledge seems to become mislaid from time to time. Certain basic properties of materials, such as their ability to move through changes in temperature and moisture, seem to be overlooked and a rash of difficulties occurs.. The level and nature of defects in building construction currently encountered suggest that more guidance is required. The purpose of this project is to provide this positive guidance in a suitably compressed form. It does not set out to describe every possible way in which a building may become defective. Such a task would scarcely be possible and certainly would not be particularly helpful. It seems better to aim at identifying the principal defects and their causes which, if wholly eliminated, would prevent the great majority of the defects which currently occur, save occupants of buildings much annoyance and discomfort, and reduce the national bill on maintenance and repair by scores and, possibly, by hundreds, of millions of rupees annually. The project aims to identify the nature and cause of important defects occurring in buildings, with emphasis on those affecting the fabric of a building and its associated services. It does not deal with issues of aesthetics, lighting, or thermal or acoustical comfort. While concerned primarily with the avoidance of defects, the text also gives guidance to aid in their correct diagnosis when, unfortunately, the situation demands cure rather than prevention. Except in a general way, the repair of such defects is not covered. Any one specific failure needs a detailed examination to decide on the most appropriate repair, form this depends not only upon technical considerations but also upon the type of building and its age, and upon related economic and social considerations. There are few standard solutions to problems of repair. Most defects occur through the effects of external agencies on building materials and the two or three succeeding methods used for the identifying the defects in structures. In this project we case study of three different type of structures which are as follow: 1. New residential building: raj residency, 150 feet ring road, Rajkot- 360005 2. Overhead tank: near dharma (reliance) cinema, rajkot-360003 3. Lab (chemical industries): ayu chemical lab, gondal road chowkdy, Rajkot.
