What is a limited subsurface investigation?

In Depth Property Analysis. At the most basic level, a Phase II Limited Subsurface Investigation is an environmental site investigation that collects physical samples and subjects them to laboratory analysis specific to chemicals of concern (COCs) identified in the initial environmental site assessment.

What is sub-surface investigation?

The subsurface investigation is the primary method for gathering the data to generate a report of geotechnical engineering recommendations. Subsurface investigations include the sampling and examination of the below surface materials including soil, rock, groundwater and any manmade materials.

What information is gained by making a subsurface investigation?

This often requires the geotechnical engineer to work closely with the structural design engineer. Some of the main types of information that the subsurface investigation needs to provide are: - Depth, extent and thickness of each soil or rock stratum.

What are the objectives of subsurface investigation?

The purpose of conducting a subsurface exploration is to describe the geometry of the soil, rock, and water beneath the surface; and to determine the relevant engineering characteristics of the earth materials using field tests and/or laboratory tests.

What is a subsurface exploration?

Subsurface Exploration, at its simplest, is the process of investigating what lies beneath the Earth's surface.

What is the method of subsurface detection?

Ground penetrating radar provides high-resolution images of subsurface features. It can detect small objects and differentiate between materials with varying properties. In contrast, seismic surveys offer lower resolution but are effective for mapping larger geological structures.
