Geotechnical Investigation Survey in Raipur 

Construction work needs to start beneath the surface. It is important for any engineering designer to know the properties of the ground beneath the building site before he starts designing a building, industrial plant, warehouse, road, bridge, or any other type of construction.

A Professional Geotechnical Investigation Survey in Raipur will provide the engineer with the required information regarding the ground conditions prior to the start of any construction activity.

Raipur is witnessing an increasing pace of development in its residential, commercial, industrial, institutional, transport, and infrastructure sectors. With each passing day, the need for ground investigation to understand the underground conditions which are not obvious at first sight increases.

Accurate Surveying and Construction offers geotechnical investigation services in addition to DGPS, GPR, Total Station, drones, topographic, land, mine, pipeline, and other specialized surveys.

The Problem: What is Hiding Below the Ground?

There is likely a huge difference between the soil conditions at two adjacent construction sites. While one may feature dense soil just below the ground, the other may be filled with soft, weak, expansive, and/or saturated soils.

Engineers are unlikely to have enough knowledge about the following aspects without any investigation:

Type of soils

• Depth of soil layers
• Ground water condition
• Strength of soils
• Soil bearing capacity
• Settlement possibilities
• Depth of hard strata

That’s why geotechnical investigation is a necessary step for any construction project.

What Is Geotechnical Investigation Survey?

Geotechnical investigation is an in-depth study of the soil, rock, groundwater, and other subsurface properties of a construction site.

Generally, a geotechnical investigation involves field exploration, borehole drilling, in situ testing, sampling, laboratory testing, and interpretation.

Based on project needs, a geotechnical investigation can include:

Borehole Drilling
Borehole drilling enables access to deep soil and rock layers and creates subsurface profiles.

Standard Penetration Test (SPT)
SPT gives resistance to penetration values that will enable engineers to assess soil conditions.

Soil Sampling
Disturbed and undisturbed soil samples can be taken for further laboratory testing.

Observation of Groundwater Levels
Water level observations can be done since water conditions affect excavation and foundations design.

Lab Testing
Soil samples can be tested for physical and engineering properties.

Plate Load Test
Plate load test can give information about soil behavior under loading when required for specific projects.

ASurvey lists these techniques as their soil investigation and subsurface exploration survey services in Raipur.

Importance of Geotechnical Investigation in Raipur

The Geotechnical Investigation Survey in Raipur makes it possible to convert unknown soil conditions into valuable engineering data.

Foundation Design

There is a need for the structural loads to be transferred effectively to the ground by the foundation systems. This requires investigation to get data to be considered during design and selection of an appropriate foundation system.

Identification of Weak Strata Early

Investigation can help identify any soil layer which is weak or varying and will require additional engineering attention.

Groundwater Considerations

Groundwater may influence the excavation process, construction methods, behavior of the soil, and foundation considerations. It is thus essential to document groundwater conditions for the right projects.

Lowering of Construction Uncertainty

It is essential to have information about the ground profile prior to the construction of a project.

Good Engineering Data Collection

Proper preparation of the geotechnical report ensures collection of good engineering data.

Geotechnical Investigation Services in Raipur: Typical Procedures

Professional Geotechnical Investigation Services in Raipur usually proceed according to a pre-planned schedule.

1. Site Investigation

The investigation team examines the project site in terms of topography, accessibility, presence of buildings, drainage, and available data about the site.

2. Investigation Planning

On the basis of the project requirements, the team finds out the suitable locations of boreholes, depth of investigation, field tests, sample collection, and laboratory tests.

3. Borehole and Field Investigation

Boreholes are drilled at the designated places. The SPT, sampling, groundwater investigation, and any other necessary field investigations are conducted.

4. Sample Collection

Suitable samples are collected, labeled, preserved, and sent to the laboratory for the necessary tests.

5. Laboratory Tests

Depending upon the project requirements, some possible laboratory tests include moisture content, grain size analysis, density, compaction, shear strength, consolidation, permeability, and many others.

6. Data Interpretation

Field observations and laboratory data are analyzed together in order to obtain an understanding of the site geotechnical data.

7. Technical Report

A typical report includes borehole logs, soil profiles, test results, groundwater investigation, graphs, interpreted data, and engineering recommendations, if any.

Advanced Investigations of Complicated Sites

It is not necessary that all sites have to go through the same type of investigation programme.

Depending on the project requirements, the investigation may include:

• Electrical resistivity investigation
• Seismic investigation
• Plate load test
• Bearing capacity of soils
• Laboratory tests
• Ground water studies
• Pile investigation

The use of electrical resistivity and seismic investigations will provide more data regarding variations and geology of the subsurface where needed.

Geotechnical Investigation and Piling

In some cases, large buildings may need piles because of ground conditions close to the surface and the need for deeper foundation.

For piling, the engineers may require knowledge of:

• Stratification of soils
• Depth of the soil stratum
• Ground water
• Soil resistance
• Behaviour of the piles
• Underground obstructions

Therefore, geotechnical investigation is an important source of information for piling and foundation planning.

ASurvey provides pile investigation and geotechnical investigation among their services.
