Engineering and geological surveys (EGS)
Engineering and geological surveys are carried out before the start of any construction, but have their own specifics and features depending on the type of object; Their purpose is to obtain the most complete information about the properties of the geological environment of the survey site, this includes data on:
terrain
geological structure of soils
composition and properties of soils
hydrogeological conditions of the site
geological processes on the site
Types of work that includes geology for construction
Geology for construction is carried out at the stage of project development or preparation of working documentation. It may include the following types of work:
-
Collection and study of engineering survey archive materials
-
Route observations
-
Drilling of geological wells and excavation of pits if necessary
-
Geophysical research
-
Field and laboratory studies of soils
-
Laboratory studies of groundwater
-
Preparation of a technical report, which includes systematization of the obtained geological information, development of a digital terrain model (DTM)
-
Defense of the report in the examination, correction of comments
Risks associated with failure to conduct engineering and geological surveys for construction
-
Uneven building settlement
-
Cracks appearing
-
Flooding of the basement
