Geotechnical Investigation Survey in Delhi NCR 

Successful construction begins with understanding the ground. Prior to the construction, excavation, piling, or infrastructural development, it is necessary to obtain reliable data on the state of soils, rocks, water bodies, and the entire subsurface structure. Geotechnical Investigation Survey in Delhi NCR is a crucial step at this point.

Continuous construction and development of Delhi NCR involve residential buildings, commercial constructions, industrial facilities, highways, metro projects, warehouses, bridges, and other infrastructural objects. Each site requires specific investigation prior to the construction of foundations because of different states of soils and groundwater.

Accurate Surveying and Construction offer professional surveying and investigation with the use of the services of experienced civil engineers, surveyors, equipment and techniques. The company's portfolio includes such services as geotechnical investigation, soil testing, GPR survey, land survey, topographical survey, piling work, and other specialized works.

Geotechnical Investigation Survey – What Does It Mean?

Geotechnical investigations refer to the process of evaluating the geological conditions at a proposed construction site. This helps in assessing the engineering behavior of soil and rocks and assists in providing data needed for planning purposes.

A Geotechnical Investigation Survey in Delhi NCR could include activities such as boring, soil sample collection, standard penetration test, groundwater observation, field testing, laboratory testing, and technical investigation report.

This data assists engineers in making appropriate decisions about the type of foundation to use, excavation methods, piling needs, among others.

Importance of Geotechnical Investigation in Delhi NCR

Delhi NCR consists not only of Delhi but also of fast-developing regions like Noida, Greater Noida, Gurugram, Ghaziabad, and Faridabad, and each location may have different construction conditions.

The existing service information provided by Accurate Surveying and Construction about Delhi NCR states that there are different soil conditions in this region, which consist of alluvial deposits and the Aravalli belt areas.

Geotechnical Investigation in Delhi NCR will help to determine soil properties before starting construction.

Essential Aspects of a Geotechnical Survey

1. Desk Research & Site Exploration

The team conducts a desk research and explores the site with the help of maps, past history & data from neighboring projects.

2. Boring

Boring to a certain depth based on the load & dimensions of the structure. Disturbed and undisturbed samples are taken at various depths to note the soil profile.

3. Standard Penetration Test (SPT)

Conducted inside the bored holes based on Indian standards, this test provides N-value indicating soil density and bearing capacity.

4. Groundwater Level Observation

The groundwater level is noted and observed as it is essential in basement construction, pile foundation design, and excavations.

5. Laboratory Tests

Tests conducted include grain size analysis, moisture content, Atterberg limits, shear strength, consolidation, and chemical composition such as sulphate and chloride contents. Reliable soil testing in Delhi NCR forms the basis for decision making.

6. Plate Load & other Tests

Some of the projects require conducting plate load test, cone penetration tests and geophysical investigations as well.

Benefits of a Professional Geotechnical Investigation

• Safer structures: Structures are constructed according to the actual geology.
• Financial savings: Over-design is avoided in addition to costly failures and repairs.
• Legal compliance: A soil investigation report is necessary for many permits and structures.
• Proper planning: Information about groundwater and strata makes excavations predictable.
• Risk mitigation: Problematic soils like soft sandy or clay strata are detected early on.
• Increased longevity of buildings: A properly supported structure requires less maintenance.

Combining Geotechnical Investigation with Other Surveys

Contemporary constructions may involve more than one survey process at one construction site. Combination of different surveys can give more detailed insight into a project area.

For instance, GPR may assist with investigating chosen subsurface features, while DGPS and Total Station Surveys can assist in accurate positioning and measurements of the site. Geotechnical investigation deals specifically with engineering properties of soils.

Accurate Surveying and Construction offers wide range of surveying services, including GPR, DGPS, Total Station, drone, hydrographic, geological, topographical, land, geotechnical, and soils testing surveys. Combination of proper surveys will allow collecting required information for each construction stage.

A Step-by-Step Guide to Professional Geotechnical Investigation Survey

The procedure typically takes a structured order that is usually as follows:

Step 1: Project Discussion
The technical team becomes aware of the nature of the project, its location, the structural needs, and the investigation goals.

Step 2: Site Assessment
The project site is assessed and investigation points are selected.

Step 3: Field Investigation
Tests on boreholes, sampling, SPT, groundwater, and any other field tests are carried out.

Step 4: Laboratory Investigation
Investigation on the physical and engineering properties of the soil samples collected is carried out.

Step 5: Data Assessment
Results from the field and laboratory investigations are assessed by the technical professionals.

Step 6: Technical Report
The report is prepared.
