Building Survey

A building survey is an engineering work to determine the load-bearing capability of the main units and structures of the building, the state of its utility systems and its general technical condition. The main task is to detect any critical defects and deformations which prevent further safe operation of the construction or to determine whether it can be reconstructed. Following the results of the survey, a conclusion can be made about the safety and functionality of the building, its foundations, load-bearing structures and utility systems. Based on the results of the survey, works on building renovation design can be started.

The main work in buildings survey is the analytical comparison of the existing design documentation with the findings of the visual and instrumental analysis received in the course of work. In the process, actual values of the predetermined dynamic and geometric parameters specified in the survey plan are measured; these parameters, called "controlled parameters”, characterize the current state and actual operation capabilities of the main elements of the building under survey.To instrumentally determine the strength and technical state of the structures, APBP uses modern research devices, such us reinforcement detectors, flaw detectors, dynamometers, densimeters, crack width gauges, sclerometers, thermographs, tensometers, deflectometers, using a variety of methods to test materials – acoustic, ultrasonic, neutron, etc.

The survey results are documented in the form of the technical statement, issued in due form approved by the regulatory instructions, with the description and photofixation of the defects, findings of the works performed and recommendations on the reinforcement of the structures. The works end with the qualified statement that determines the possibility and conditions of the further safe operation of the building, eliminating any possible emergency situations in the future, and instructing on the necessary restoration, reinforcement and modernization of the construction.

   Standard situations that require surveying the technical state of the buildings:

  1. Two years after the building or the structure was put into operation.
  2. Once every ten years in the course of operation for standard capital construction projects.
  3. Once every five years for the buildings, constructions and their separate structures located in the zones of seismicity, permafrost, exposed to high loads, aggressive environment, water or vibration.
