What is ground surveying?

In short, the study of the underground. It is the examination of the basic gold of the structures to be made. The weight of the structure itself,the load given by the wind, the snow load accumulated when the snow falls, if there are moving loads such as trains passing through the structure or the loads of vibrating machines working within the structure, finally, the loads coming to the structure at the time of the earthquake are taken into account. This is to examine the ground or rock conditions that come under the foundation of the structure according to static and dynamic loads.

Geology is useful from the disciplines of Geophysics and civil engineering while soil surveying. Many methods are used while ground research is carried out. The most common ground drilling, seismic refraction, seismic MASW, microtremor, resistivity, presiometer and laboratory services where samples from drilling are examined.

As a result of all these studies, the soil data report, which we call soil survey, is formed.In the light of this data, civil engineers make static calculations of the structure.

Soil survey data is vital for building statics.

It also occurs at this stage if improvement on the basis of structure is required. Uses for structural statics soil survey and geotechnical data also affect the amount of concrete and iron to be used in the structure. The ideal and optimum engineering benefit is possible only with soil survey.

Who does the ground surveying?

Geological engineers, Geophysical engineers, civil engineers, geotechnical graduates, etc.

He is mainly engaged in geology and geophysical engineers in our country. Standards and regulations in our country authorized these two professions. The formation of the sector is also in these two engineering groups. To be able to do soil survey, it is necessary to have been trained in geosciences.

How long does the ground study take?

Ground surveying takes 1 day on the parcel and the field can take many months. Its duration depends on the size of the parcel and how a ground survey is requested.

For example, let’s consider a parcel on the site of the construction of 500 square meters. Municipalities and development directorates determine what will be done in the soil survey work to be done in this field. Taking into account the current earthquake regulations, 3 units of 20 square meters of soil survey drilling and 2 seismic refraction 1 resistivity 1 microtremor 1 well preciometer tests are required for 500 square meters. Work on this land takes about 2 days. 2 days in the office soil survey report calculation and writing takes. In short, plots up to 1000 meters of Soil Survey time can say 1 Week. This lengthens as the field grows.

Building floor survey prices?

It depends on the content of the work to be done. It varies by province. The work depends on the terrain. It depends on the bureaucratic processes that will be encountered during the project.

For a 500 square meter residential parcel, it ranges from 5000 10000 lira in Istanbul to 5000 8000 lira in Kocaeli to 6000 9000 lira in Yalova to 4000 7000 lira in Sakaria.

These prices also vary according to competitive conditions. For earthquake investigation/performance analysis of old buildings, these prices fall up to 2000 tl.In urban transformation projects, the cost is reduced because only seismic refraction masw is required. It can be made up to 1000 pounds. The situation in industrial structures is changing. It varies between 10000 tl and 100000 tl according to the desired study.
