Engineering and technical center "Quality" provides services for the examination of buildings, structures and designs with the execution of a full technical report.
Buildings section number 1.
The right to carry out this type of work is confirmed by a certificate of admission.
The survey is caused by the need to evaluate the technical condition of the building structures due to the existing deformations of the structural elements.
The design documentation for the examination of the building structures includes the following types of work:
- Perform measurement work to determine the parameters of the structural elements of the building;
- assessment of the actual technical condition of the main supporting structures and the building as a whole;
- issuance of recommendations to ensure the further operational suitability of the building.
Based on the results of the survey conducted in accordance with the requirements
SP 13-102-2003 and GOST 53778-2010, a present report compiled, including:
- Drawings of the building (plans, cuts, facades);
- results of the examination of structures (walls, overlapping, coatings, structural elements) with the photo application of the existing defects;
- conclusions to assess the technical condition of the structures;
- Recommendations to ensure the further normal operation of the building.
When performing work, the following documentation was used:
1. Technical certificate on a warehouse building.
2. Fragment of topographic shooting site of the building.

Overlapping basement - reinforced concrete plates.
Coating - reinforced concrete ribbed and crowded plates.
The beam, which relieves the slabs of the overlap in the axes "1" - "2" - metal.
Jumpers over window openings are metallic.
Roofing - from roll-up materials.
Plans, cuts and facades are shown on sheets of graphic part and in photosappendix 4.1.
