Pre-Design Survey Work For Reconstruction And Overhaul Of Buildings

Abstract

The main problems regarding the organization of high-quality implementation of pre-design survey work carried out during the reconstruction and overhaul of buildings and structures and their solutions are considered. The specifics of conducting engineering surveys and survey work with the use of modern technical means and equipment, making it possible to accurately assess the reliability and safety of buildings, are underlined. The results of the survey of the technical condition of bearing structures and engineering-geological surveys of the administrative building site in the Yamalo-Nenets Autonomous District (Salekhard City) are given as an example of high-quality pre-project studies. Numerous defects of reinforced concrete structures of foundations, formed as a result of construction and installation works - poor quality pile splicing to the design level of the bottom of the grillage with low strength concrete without anchoring the reinforcement, tilting of separate piles and factually their emergency condition - were revealed. According to the results of the survey, recommendations were developed to strengthen the bearing structures. The importance of the problem of creating an engineering organization, whose activities will be aimed at improving the survey work, including the survey of the technical condition of existing buildings, and the creation of high-quality overhaul and reconstruction projects based on them, is noted.
