How much ground investigation is enough for a mid-rise building?
- One borehole per footprint
- A grid of boreholes
- Boreholes plus CPTs

Boreholes plus CPTs where the budget allows. A CPT gives a continuous profile that boreholes alone miss.

Whatever the budget allows is the honest answer, but a thin investigation usually costs more later.
