Why Geotechnical Investigation is important?

Why Geotechnical Investigation is important?

Geotechnical investigation is an integral part of the construction process which is done to obtain information about the physical characteristics of soil/rock around a site. These investigations form the basis for planning, designing, and constructing the structures.

Are geotechnical reports required?

Geotechnical reports for building construction are required for nearly all projects when permit applications are submitted. Additionally, projects that involve steep slopes, elevated seismic code, roadways, underground transmission, oil, and gas lines rely on geotechnical reports.

What is the purpose of a site investigation?

The objective of a site investigation is to gather the information needed to carry out the risk assessment, in order to be in a position to assess the presence and significance of contamination of land.

What is the importance of site investigation?

The purpose of a site investigation is to make sure that the groundwater conditions are ideal, that the physical properties of rock and soil can accommodate construction, and that the building will be safe for anyone who enters it.

Who is responsible to provide the geotechnical report?

Geotechnical Engineer
Often, Geotechnical Reports are provided to the contractor as a reference document. Structural Engineers may also request or require the Geotechnical Engineer to review structural drawings and specifications to confirm the correct interpretation of geotechnical recommendations.

Is a geotechnical report the same as a soil report?

While soil report and “geo” report are often used synonymously, they refer to different yet related services. A soil report is prepared by a geotechnical engineer, or a soils engineer. As such, most reports include both a soil engineering and geologic portion, and as such are referred to as soil/geology reports.

What are the benefits of site investigation?

Helps Determine the Construction Materials A site investigation helps to determine the most suitable materials to use in construction. Some materials may not hold onto certain soils for long, which means cracks on the walls or even floors may appear not long after construction is finished.

What are the three important aspects of a site investigation?

Site investigations should include:

• Susceptibility to groundwater levels and flow.
• Underlying geology, and ground and hydro-geological properties.
• Identification of physical hazards.
• Identification of methane and other gases.
• Determining an appropriate design.
• Providing soil parameters for design and construction.

Why is geotechnical investigation important in civil engineering?

The purposes of a Geotechnical Investigation are to investigate the soil and geologic conditions of a property and to provide recommendations and design criteria for construction. Geotechnical investigations have become an essential component of every construction to ensure safety of human beings and materials.

What is a geotechnical report used for?

The geotechnical report is the tool used to communicate the site conditions and design and construction recommendations to the roadway design, bridge design, and construction personnel.

What is included in a geotechnical report?

Parts of the geotechnical report Location and surface conditions: specific address, current use, surface coverings, elevation, drainage, etc. Subsurface exploration data: soil profile, exploration logs, lab or in-situ test results, ground water conditions. Interpretation and analysis of data.
