Inspection of foundations and structures

A foundation survey may be needed invarious cases. The most obvious options are long-term construction, which has been decided to resume, or simply old buildings, in which some reconstruction is planned to a modern day. Often it happens that the customer begins to freeze the construction for a while, because he has some problems. And then, when it comes time to re-enable it, the reliability of the constructed structure is in doubt. Has not the foundation received any deformations invisible to the eye that will affect the strength of the future building? Survey of foundations is able to answer these questions.

Old buildings are often reconstructed withsubsequent superstructure, increase in number of storeys. And this means an increase in the load on the foundation of the structure. To find out whether it is possible to translate such plans into practice, and first of all, a survey of foundations is done. The results of such surveys may lead to changes in the design, use of lighter structures and materials, or a reduction in the estimated number of storeys of the reconstructed building. In some cases, it is possible to strengthen existing foundations, but more often inspection of dilapidated buildings leads to their recognition as emergency.

Inspection of structures of buildings and structuresbegins with a visual inspection. If the cracks already visible in the walls, it is unlikely that experts will be able to give a positive conclusion. Then follows an instrumental examination. For example, with the help of a georadar, it is possible to establish the presence of defects inside reinforced concrete structures, without violating their integrity. Mechanical, ultrasonic, vibrational and other methods are used, allowing to make a complete picture of the presence of defects and damages.

The survey of premises is, as a rule, notduring the construction, and before the purchase. In this case it is possible to establish with absolute guarantee what hidden defects a house, cottage or office building has, what mistakes were made in the course of its construction or operation, how much will it cost to eliminate them, whether it makes sense to purchase real estate with such characteristics. Such a procedure can also give an answer to the question "Is it possible to repair or reconstruct this room".

As a rule, a survey is first conductedfoundations. Then, the technical condition of the walls and other supporting structures, engineering communications, and also the roof is assessed. Violation of their integrity is often recorded in photographs. Surveys are also conducted after various emergency situations, for example, after a fire, in order to assess whether the surviving structures will recover, how much money may be needed for this. In addition, such work should be ordered if there are doubts about the quality of the work of the builders. The results of the survey and construction expertise can be used in court.
