Minimize Risks and Complications With Soil Testing for Foundation Construction
A geotechnical soil investigation is one of the earliest and most critical steps in excavation and construction projects. These site investigations provide essential information about the suitability of the earth at a proposed construction by determining soil conditions, water presence, and the location of rock. The results of geotechnical soil testing help FNA Engineering Services design plans that ensure the efficiency of projects and the long-term performance of a structure.
Soil testing for construction sites begins by drilling a multitude of holes to collect samples. Once laboratory testing is complete, FNA’s team of geotechnical engineers designs ideal, risk-mitigating foundation solutions based on subsurface conditions, type of structure, adjacent buildings, and various requirements. FNA’s geotechnical soil testing expertise is crucial to each subsequent phase of a project as well as a structure’s safety and long-term success.
What Does a Geotechnical Soil Investigation Test?
Geotechnical site investigations provide a wealth of information about the properties of soil to engineers, developers, and contractors . Understanding and classifying the types of soil at a site and how the dirt, silt, soils, and rock beneath a structure will absorb stressors and react to saturation, seismic activity, compaction, and many other factors are important to the proper performance of a foundation.
FNA’s geotechnical investigation team closely studies soil samples and can conduct several tests, including:
- Standard penetration tests (SPT)
- Moisture content tests
- Dry density tests
- Compression tests
- Shear strength tests
- Cohesive soils tests
- Consolidation tests
- Soil compaction tests
The insights provided by soil testing for foundation construction enable FNA’s design team and structural engineers to develop a safe, efficient, cost-effective, and streamlined plan. Testing of subsurface conditions should be completed during the preconstruction phase (often required by law) and even before a property is purchased, whenever possible. But geotechnical soil investigations can also be an indispensable part of the construction process as excavation progresses.
