Before any skyscraper, highway, bridge, airport, or industrial facility is built, engineers must first understand what's hidden beneath the ground.

In this video, you'll see the complete Cone Penetration Test (CPT) process—from equipment mobilization and site setup to cone penetration, real-time data collection, interpretation, and engineering analysis.

Learn how geotechnical engineers evaluate:

✔ Soil strength
✔ Soil layers
✔ Tip resistance (qc)
✔ Sleeve friction (fs)
✔ Pore water pressure (CPTu)
✔ Foundation design data
✔ Ground improvement requirements

This is one of the most widely used in-situ soil investigation methods in modern civil engineering and infrastructure projects around the world.

Whether you're a civil engineering student, geotechnical engineer, construction professional, or simply curious about how massive structures begin, this video takes you through every step of the CPT process.
