Engineering geology has evolved since the mid-20th century from simply collecting and observing ground data into decision-led modelling and risk management. This expanding scope is catalysed by a greater need for engineering geologists to inform planning decisions and shape spatial development to achieve a sustainable, resilient society. Shifting away from solely engaging with the technical side of characterising strata or deriving parameters for infrastructure reflects the increasingly influential role they must play.

The article extends this point by challenging how ground investigation is understood and used, pushing for it to play a greater role in managing social risk. Ground conditions affect more than just structures; they inform how endurable buildings are, their reliability and flexibility, and how much confidence communities place in their local infrastructure. Misunderstood ground conditions not only stall projects and increase costs, but also disrupt services and produce unsafe buildings, culminating in a reduction of trust by the people who use key institutions such as hospitals, housing, and schools. Therefore, it is integral that ground conditions data is used to help understand infrastructure in terms of lived experience.

A particularly interesting upcoming challenge is the UK government pledge to build 1.5 million new homes at an average rate of 300,000 homes per year, which serves as a prime example of the need for effective ground investigation to ensure successful housing and social equity. Considering that 6.3 million properties in England (1 in 5) are at risk of flooding, with many at risk long before climate change projections, there is a long-term social cost to underestimating ground and hydrological risk. Moreover, the article reframes technical concerns as strategic concerns. Issues of slope instability or drainage failure can be mitigated through careful, thoughtful planning right from the outset regarding where to build, what investigations are required, and how early uncertainty is addressed.

The article is hopeful that through a more holistic use of ground conditions and improved ways engineering geologists convey and interact with others, we will see an increase in cohesion between developers, locals, and engineers. Reducing this fragmented nature will ensure a better response when structural issues come to pass. A push for utilising ground conditions as early as environmental assessments, hydrology, and asset operations will enable the value of the ground to be explained more clearly and earlier, ultimately aiding decisions about funding, policy, and places.
