| Description | Geological and geotechnical survey is an essential part of preparation for the design and following construction of underground structures. Quantitatively and qualitatively conducted survey has a decisive influence on the accurate planning of costs in preparation of construction and to reduce any unexpected events. To correctly assess the actual state of geological and geotechnical properties of the rock complex is important to observe every single part of survey. Nowadays, the trend is to reduce resources spent on geological surveys. This leads to a lack of resources due to the limitation of carried on work. Series of unexpected situations are reviled during the actual construction. We have examples of well-secured surveys, that they avoid the necessity of extra work and revealed potential risks in construction. But sometimes, the opposite situation may occur. Engineering geological survey is a set of information that adds value to the complex geological structure. Drilling survey as the most common way of getting information provides only a partial information. Survey of surface around the building sight, in the form of a simplified mapping, is an indispensable source of information. In combination with geophysical and other methods, we can get a wide range of data that geologist / geotechnical can well interpret. However, if there is not enough time and financial area, it is not possible to cover the entire range of data and it is necessary to turn to archival information. It is necessary to count with an estimated production of these documents with regard to the current state of knowledge at that time. Then it is quite common that the available detailed geological maps may not fully reflect the actual state of the geological structure of the area. Also, to this are related certain responsibilities from the current surveys and construction to future generations. And the newly acquired information will facilitate similar implementations in the future. Cooperation among geologist, geotechnical engineering, designer and contractor in all phases of construction on the basis of adequate and well-processed survey leads to cost-effective implementation of project well in advance eliminates the occurrence of unexpected events. |
