Your best solution to date?
The BRICK model of soil behaviour.
Why is it significant?
It helps us to understand many features of ground behaviour. It is used in our analysis of many geotechnical problems and it has led to extensive research in academia.
Your particular skill?
Geotechnical design, especially numerical analysis and code/safety based thinking.
The behaviour of the world beneath our feet.
The opportunity (and challenge) to extend knowledge and understanding in a context of relevance to practical design.
The ground is fascinating and very complex. But now the real challenge is energy!
