Why does it matter?

Before we build above,we understand below.

Before an MRT tunnel is excavated, a skyscraper rises or an airport expands, engineers must first understand what lies beneath the ground.

Soil investigation reveals subsurface conditions. Instrumentation and monitoring then track how the ground and structures respond, helping engineers make informed decisions throughout construction.

The engineering journey

Select a stage to explore

Stage 01 / 04

Understand the ground

Understanding the ground starts with reviewing site information, ground conditions and potential geotechnical constraints.

A clearer picture of the conditions below the site.

Explore soil investigation

Exhibit 01 / Soil Investigation

Discover what lies beneath.

Before foundations, tunnels and retaining structures are designed, engineers need reliable information about the ground.

Borehole drilling, soil and rock sampling, in-situ testing and geophysical surveys help reveal subsurface conditions and inform engineering decisions.
