The nature is typified by continual changes, in some cases by predictable evolution, however, much of nature is unpredictable. When unpredictable natural events become extreme in their occurrence, they may constitute a danger to life and environment. These in turn cause generally predictable problems of various kinds: environmental; health; social, economic, political; and administrative. One can then take steps to prevent the disaster, or prepare for the disaster and substantially reduce, or mitigate, its impact. At B S Engineering we provide services to safe the life and envoirnment.
