Risk assessment

Our organization offers its services to insurance, financial and construction companies to assess the risk of occurrence of a particular emergency situation and the security assessment of the building or structure against natural hazards. Our experts will help in optimizing the design documentation and construction process and increasing its efficiency taking into account local natural specifics.

The risk of occurrence of emergency situations of natural and technogenic character, from the point of view of insurance, are rare according to the frequency of its repetition, but with high destructive capability. Usually, consequences of emergencies are large economic losses, up to complete destruction of assets and costly measures for its repair and restoration.

According to the world Bank over the past 20 years natural disasters in the world have affected 4.4 billion people, claimed 1.3 million lives and caused economic losses of USD 2 trillion. Statistics shows that the danger level of natural disasters is increasing. It is expected that annual losses from natural disasters such as earthquakes, tsunamis, cyclones, floods, will increase from about 300 billion $ to 415 billion $ by 2030. The number of victims in the world suffered from the devastating natural phenomenon in recent years increased by 4.3% and victims — by 8.6% annually. Economic losses increase by 6% per year on average.

The exact time of occurrence of a particular emergency situation with the correct date of its origin is a quite complicated task, for example, to predict the exact date of the earthquakes, even taking into account current scientific and technical progress, is still not possible. However, to assess the risk of earthquakes in a certain period of time is a solvable task.

Often the risks of man-caused emergency are the consequence of unaccounted natural conditions, complicated by one or another factor, for example, construction in the regions with the development of atmospheric catastrophic phenomena of nature – heavy rains, hurricanes, and tornadoes. For instance, these phenomena according to the EMERCOM affect 28% of the total number of emergencies in Russia. We all remember the tragic consequences of the floods in 2012 in the Krasnodar Region caused by heavy rains.

Well known that a large part of Russia, a significant part of Canada, China, Norway, and other countries covered by permafrost rocks. These areas are very rich in mineral resources, and the world's largest companies lead the territory development in our time. The specific properties of frozen soils, global warming trends lead to the development of complex engineering-geological processes at the base of plants, to emergencies and destruction of buildings and structures.

The special soil composition, state and properties also include swelling, subsiding, soft, etc which are spread throughout the world. These soils under environmental change (humidity, temperature, vibration, etc.) is moving into a new state, which is accompanied by a weakening of its construction characteristics, emergency deformations of buildings and structures built on these soils without taking into account its specific properties.

For example, subsiding soils (loess and others) when humidity increases, the result of soaking them up from external sources or from below — by the impoundment provide additional vertical deformation — subsidence from external loading and (or) the self-weight of soil. When designing on such soils an engineering preparation and layout of construction sites, types of activities used to ensure the normal operation of buildings and structures (elimination of subsidence properties of soils; the cutting subsiding soil piles; construction activities), the impact on the projected design uniform and non-uniform vertical (subsidence) and horizontal displacements of the subsoils, presence in the zone of influence of new construction of surrounding buildings and their technical condition and other also should be taken into account.

Swelling soils (clay) when humidity increases, the increase in volume. When design buildings and structures on such soils there is a possibility of swelling of soil due to rising of groundwater or infiltration - moistening of soils by production or surface waters, due to the accumulation of moisture under structures to a limited depth zone as a result of violations of natural conditions of evaporation during construction and asphalting of the territory (shielding of the surface). Swelling and shrinkage of soil in the upper part of the unsaturated zone can occur due to changes in the water-thermal regime (seasonal and climatic factors) and other factors.

Structure bases, composed of filled soils, must be designed due to its significant inhomogeneity in composition, non-uniform compressibility, the possibility of self-compaction, especially under vibration impacts, changing of hydrological conditions (soaking), and also due to decomposition of organic inclusions.

A threat to buildings and structures pose a dangerous geological processes such as karst, landslides, underwashing, mudflows, avalanches, sinking and flooding of territories and other.
