CIPA 2003 XIX th International Symposium, 30 September - 04 October, 2003, Antalya, Turkey
• Working prospecting shafts, including the ones with a
discharge
• Geophysical examination methods
The following works are conducted as a result of engineering-
geological examinations:
• Determination of a geologic-lithological construction
and engineering-geological conditions
• Determination of hydro-geological conditions
• Determination of physic-mechanical properties of the
soil
• Assessment of a potential development of unfavorable
engineering-geologic processes
• Determination of the construction and resistance
characteristics of the foundations
• Assessment of the carrying capability of basements
and foundation soils
• Issuance of recommendations related to re
enforcement of basements and foundation soils
Examination of foundations and basements include the
following works:
1. Examination of foundations.
Such examination comprises the working of prospecting shafts
(including the ones with a discharge even when a very
insignificant inflow of water is present) in order to determine
types, constructions, geometric parameters, materials and depth
of foundations; disclosure and description of defects and
determination of the condition of foundations; determination of
resistance characteristics of foundation materials applying
methods of non-interfering control.
2. Examination of the foundation ground.
In the course of such examination the following works are
performed: selection of soil probes of broken and non-broken
structure directly out of the foundation base; drilling of holes
with a 10-meter depth out of prospective shafts selecting
samples of soils and water; field tests of the foundation ground
in prospecting shafts, including shifting, stamp test and
conducting electro-dynamic boring.
3. Issuance of a report on the condition and supporting
capacity of basements and foundation grounds.
In order to prepare a final report the following works are to be
completed: calculation of the degree of strain under the
foundation base that resulted from the existing load; assessment
of the carrying capacity of basements; assessment of the
carrying capacity of the foundation ground.
Examination of carrying constructions of on-the-ground and
underground parts of buildings comprises the following works:
Collection of initial information:
• Obtaining and analysis of historic and archive project
materials, results of previously conducted
examinations, materials of operating services;
• Disclosure of production and technological influence
on the buildings.
Preparation of a constructive scheme of the building:
• Description of the scope-planning solution for the
building;
• Preparation of a three-dimensional scheme of
placement of major carrying constructions;
• Assessment of the general stability and firmness of
the building.
Measurements of constructions and their elements:
• Determination of a constructive decision, composition
and geometric dimensions of walls, ceilings and the
covering;
• Determination of sections of construction elements.
Assessment of the condition of constructions:
• Description of general deformations of the monument;
• Disclosure of mechanical defects that occurred in the
process of operation of such monument;
• Disclosure of cracks and increased deformations of
constructions;
• Determination of the extent of corrosion of steel
elements, splitting-off of concrete (if any) and stone
constructions;
• Search for fungoid affection on constructions.
Assessment of the carrying capacity of the building:
• Determination of the load onto elements of the
building with the account of completed openings;
• Determination of the strain in constructions utilizing a
prepared calculation scheme;
• Controlling calculation of elements of the building
with the account of the current condition of
constructions and resistance-related characteristics of
materials that were obtained through a series of tests.
Assessment of the overall condition of the building:
• Analysis of examination results, including an
assessment of deformation, condition of constructions
and calculation results;
• Determination of the category of the condition of the
building (normal, satisfactory, unsatisfactory,
emergency).
Preparation of recommendations in order to ensure the
operational applicability of the monument:
• Preparation of a list of elements to be restored or re
enforced;
• Preparation of recommendations aimed at completion
of hydro insulation, elimination of leaks, liquidation
of corrosion and fungoid consequences.
Engineering-environmental examinations are conducted in order
to assess contamination of soil, ground, surface and subsoil
waters with chemicals or their combinations of various toxic
categories, both of a non-organic and organic nature.
On the basis of a complex examination of natural and man-
created conditions the following works are conducted:
• Evaluation of an environmental danger and risk;
• Evaluation of a current environmental condition of
specific elements of the natural environment and
ecosystem in general, their resistance against any
influence of a man-created nature and their capacity to
return to their normal functioning;
• Preparation of a forecast of potential changes of
natural (natural-technical) systems in the course of
construction, operation and liquidation of the site;
• Preparation of a feasibility study for environmental
and compensation events aimed at the maintenance,
restoration and recovery of the environment;
• Preparation of recommendations and (or) a program
for organization and conducting of a local
environmental monitoring.
The entire above-presented complex of examinations was
utilized in the course of a complex engineering and technical
examination of the Church of Ascent in the State Outdoor
Museum Kolomenskoye in Moscow.
Over its almost five-century existence this church survived
several wars, various natural disasters, fires and restorations.
It should be noted that before the beginning of the twentieth
century even when full-scaled restoration works were conducted
more or less significant examinations of construction,
basements, foundations were never carried out.
On the basis of previously conducted examination works in
relation to the Church of Ascent in Kolomenskoye a conclusion
should be made that an acute need has arisen in the conducting
