PRACTICE PROMPT
Use this fictional setting to practise clear reasoning. It is not an assessment or institution paper.
The setting
A pile carrying 1,100 kN in stiff clay with cu increasing from 60 to 120 kPa over 12 m.
Your task
Estimate the required pile length.
What a useful response would show
Shaft and base capacity separated, with sensible partial factors.
Reflect afterwards
- What assumption mattered most?
- What would you check before using this on a real project?
- Could another engineer follow your recommendation?
