Ground Investigation - Bridges
Ground investigation
Accurate ground investigation is essential to ensure bridges stand on solid foundations. Poor subsurface knowledge can lead to settlement, delays, and unexpected costs.
VSL, via its Intrafor ground engineering team, assesses subsurface conditions, including soil, fissures, water tables, and provides geotechnical insights to inform design choices, determine ground improvement needs, and predict foundation performance.
Why ground investigation matters
Insufficient knowledge of subsurface conditions can lead to foundation systems that are either oversized or underperforming, compromising safety and increasing material costs.
Undetected weak layers, groundwater variations, or unstable slopes may cause excessive settlement, deformation, or even structural failure during or after construction.
Encountering unforeseen ground conditions once work has started often results in costly redesigns, schedule overruns, and claims. Early investigation helps reduce uncertainty and optimize project planning.

FAQs about GROUND INVESTIGATION
It should be conducted early—before foundation design—to identify soil risks and define construction methods.
Drilling and core sampling, cone penetration (CPT), groundwater mapping, and laboratory tests for soil strength and compressibility.
Yes. It helps determine whether standard pile systems suffice or if ground improvement or mat foundations are required.
