About the survey of buildings and structuresOctober, 15th, in Saint-Petersburg State Polytechnical University (SPbSPU) the conference "Problems of buildings and structures survey and ways of its solutions" took place. In his opening speech senior lecturer, head of laboratory in the department "Technology, organization and economy of construction" of SPbSPU Alexey V. Ulybin mentioned that such event has been about to happen long ago.

This article is devoted to the problem of agreed price formation on the
market of buildings and structures survey. The authors consider such
aspects as absence of one common catalogue of reference prices for
buildings and structures survey; dumping at tenders and auctions;
disparity of prices in business proposals of different organizations.
For successful realization of survey it is necessary to solve varioius
technical and organizational problems. Each of them influence on
completeness and reliability of information and thus, objectivity of
conclusions about real state of structures and building as a whole, and
also forecasting of its further exploitation. In the article the
classification and brief analysis of these problems is given.

In the article the analysis of major methods for monitoring of masonry
buildings for the purpose of cracking. Also different ways of
reinforcement are given. The authors focus attention on comparison of
national and foreign practice in this area. Modern methods of
reinforcement are depicted such as Fibre Reinforced
(FRCM) and Brutt Technologies.

The authors emphasize two types of brick walls defects: defects of
mortar and defects of masonry stones. Causes of these defects are
analysed, such as moisturing of masonry; material quality;
quality of contractor work; project errors.
In the article different types of biological destructors and mechanism
of their influence on building structures are examined. Experience in
the survey of masonry, brick, metal, wooden, reinforced-concrete
buildings damaged or destroyed biologically is depicted.
Recommendations for microbiological survey of buildings are

In the article the mechanism of water influence on different reinforced
concrete structures is considered. Two examples are analysed: influence
of ground water on the tunnel lining and influence of man-caused water
on the floor structure of industrial building.
Resistive electrocontact method of nondestructive check was developped
for estimation of residual mechanical stresses that keep in metal goods
after its production. In this article based on the results of
theoretical and experimental research the monitoring technology of
operational mechanical stresses in building structures using this
method is proposed.
The technology of facade measurement with using digital camera and
particularized software is depicted. Main adventure of this technology
is use of metric properties of transformed pictures in full measure. At
the same time the measurement process itself is minimized and
practically it is combined with designing or modelling.

Several variants of architectural monument fixing using photogrammetric
method are considered: black-and-white and colour three-dimensional
point models; black-and-white and colour orthophotomaps in
format SPO; black-and-white and colour orthophotomaps in standard
raster formats. For different aims authors recommend corresponding data
Microclimate monitoring for public and industrial buildings is
principal and single way to determine actual loads that are usually far
from design values, and to determine air parameters. The method of
thermo-, moisture-, steam- and gas-air balances is little known for
designers and so unclaimed. But the information that could be
received is objective and is a basis for design of passive buildings.
