Major building projects, like high-rise buildings, cannot be kickstarted without a foundation inspection performed by qualified and experienced professionals. Skipping this step can only lead to severe repercussions and your budget can go haywire. During the preliminary stages of industrial construction projects, it is crucial to conduct Soil testing The procedure is geotechnical in nature determining the soil below the structure. A series of boreholes are drilled in the structure, and the soil is examined. The samples are then sent to the laboratory for testing. Then, the results are compiled into a report and are sent to the structural engineer, who is the key person handling building designs.

Such tests can give the owner of the high-rise projects the confidence to proceed, as the foundation and settlement issues are minimized. Though the Soil testing provides only partial information, it is a great support to the structural engineer in providing a measure of confidence in their design. Soil testing could make the designing and certification process easier. It is important to complete this step before the finalization of the construction documents. It can also mitigate the risks involved in project building practices.

Types of Soil testing

The structural engineers of top industrial construction companies will decide on what type of soil test needs to be taken and again it depends on the type of soil. The first step in any construction planning, the test results help to determine if the soil is suitable for the construction work. For excellent performance, the soil should be able to withhold the stress coming from the structure. If the soil is weak to hold the structure, there is every possibility the structure may collapse.

Test to check the moisture content

The water content in soil is a crucial parameter for the building process. This can be tested using various methods like oven drying, torsion balance, calcium carbide, pycnometer, sand bath, alcohol, and radiation method. Among these, the oven drying method is the most precise and commonly used method. In this method, the soil sample is taken and placed in the oven to dry at 110o 5oC. The difference in both the weights is calculated and the moisture content in the soil is determined.

Test to check specific gravity

This test is the ratio between the unit weight of the soil and water. There are many ways to determine specific gravity and these include the density bottle method, gas jar method, pycnometer method, measuring flask method and shrinkage limit method. Among these above-mentioned methods, the pycnometer and density bottle method are the simplest to use.

Test to check the dry density

Dry Density Test is the process of determining the weight of the soil in a sample. It depends on the ratio and the specific gravity of the soil. The values help to classify the soil into dense, medium or loose soil. The test can be conducted using the core cutter method, water displacement method, and sand replacement method.

Test to check the limits

The Atterberg defines the three limits that exhibit the soil’s properties in different conditions. The limits are divided as liquid, plastic, and shrinkage. These can be calculated using individual tests.

Test to check the compaction

Proctor devised the test to check for the compaction of the soil. It is done by compacting the soil by reducing the air voids by densification. The compaction is measured with regards to dry density.

While starting new industrial construction projects, Soil testing is a prerequisite. It plays an integral role. The factors that are crucial for hiring a soil testing professional services are listed below:

  • The test helps to ascertain the safety quotient while constructing a building over that
  • It helps to understand if the land is on a floodplain
  • It helps to ascertain if the site is on the slope and the possibility of water run-off
  • To check the suitability of the soil for the construction of a sewer tank
  • The chances of a basement
  • Check the possibility for potential landslides

The Soil testing services help to determine these factors and ensure the safety of the constriction. There are certain limitations that are to be considered while planning the construction. Depending on the kind of soil the construction strategy is laid out. Only a professional
