Soil Investigation

Before planning for a structure, engineers perform Geo-technical Investigation or Soil Investigation activities, to obtain related information about the physical and chemical properties of soil and rocks beneath the site surface. This will help the engineers in designing earthworks and foundations required for withstanding the structure in the soil conditions. This can also be helpful for the repair of distress caused to the earthworks and structures caused by soil conditions.

Soil investigation/ Geo-technical Investigation provides the vitals of the soil which enables the Engineers for suitability of the soil materials for well informed decision making in site development and planning.

A geotechnical investigation generally includes surface and subsurface appraisal of a site. Occasionally, geophysical methods are used to obtain preliminary qualitative data about sites. Soil Investigation usually involves in-situ testing such as the standard penetration test and cone penetration test. Additionally, site investigation will often include soil sampling and laboratory testing of the retrieved soil samples.

Test pits, trenches, and large diameter boring may also be used to learn about soil conditions at depth for direct visual and manual examination of the soil and rock stratigraphy. The extent of investigation depends on whether the area is built up or not and the size of the structure.

WORK TOGETHER

Soil Investigation consists of the process

Type of soil encountered during the investigation can be peat, gravel, clay, silt, sand, or loam soil, understanding the soil properties of a site helps make good construction decisions leading to the success of the project. Therefore, the structural engineers can efficiently and accurately design the structural elements for the long-term viability and soundness of the project. The geotechnical investigation also helps to determine whether there is a need for soil stabilization and the foundation depth to attain the required soil bearing capacity.

1. Drilling

At Suncon Engineers Private Limited, we use rotary drills, percussions type of systems for drilling in the surface for carrying out Soil Investigation. Selecting the most appropriate drilling equipment is an important for any subsurface exploration. The equipment must be capable of meeting the project requirements, have sufficient mobility, and be able to convert rapidly from one drilling technique to another.

2. Soil Sampling

In land/ Engineering survey it is a vital role of control points/ baselines/ traverse survey to achieve control on large surveys in roads, railways or areas. Application of high-end instruments is necessary to achieve benchmarks like DGPS or 1’ (one second) accuracy total stations.

3. In-Situ Tests

The In-situ tests conducted at site by us are Standard Penetration Test, Dynamic Cone Penetration Test, Helical Probe Test, A Flat Plate Dilatometer Test, Plate Load Test

4.Laboratory Tests

A wide variety of laboratory tests can be performed on soils to measure a wide variety of soil properties. Some soil properties are intrinsic to the composition of the soil matrix and are not affected by sample disturbance, while other properties depend on the structure of the soil as well as its composition, and can only be effectively tested on relatively undisturbed samples.
