Engineering surveys and their role in construction

The survey work complex includes services for engineering and geodetic and geological work. Geodesy, like geology, is carried out immediately before the development of design and estimate documentation for the construction of a future facility and are mandatory stages.

As part of pre-project work, engineering and geodetic surveys usually involve performing a topographic survey of the construction site. Subsequently, the designed buildings are added to the survey and geological workings are tied in. Completion of geodetic work is the beginning of geology work on the site.

Soil research on the territory under construction is of primary importance. It is the results of geological surveys that allow planning the appropriate type of foundation for the future building, taking into account all the characteristics of the land plot and the groundwater level. Incorrect or poor-quality laboratory research, or negligent attitude of geologists can lead to destructive consequences for the building under construction.

There are frequent cases when a survey organization, using archival materials of study, neglected to take soil samples and issued a conclusion based on outdated data, not taking into account changes in the natural and climatic conditions of the site, which, accordingly, also affected the physical and mechanical properties of soils and the level of groundwater. This kind of savings can lead to incorrect calculations during design, which in turn will entail the appearance of structural defects in the new building.

When choosing a contractor for survey work, it is necessary to pay attention to the availability of the appropriate license and the necessary fleet of devices and equipment. For high-quality geology, an appropriate drilling rig is required, allowing drilling wells of the required diameter and depth. Do not forget about the experience of the contractor and the availability of letters of recommendation. A self-respecting company always cares about its image and the content of its portfolio.
