Basement heave 1

[jackson]

Any advice on how to calculate the likely heave (short term and long term) due to the excavation of a 4m deep basement in overconsolidated high plasticity clay?

You could start by performing oedometer tests in the lab to evaluate heave due to load removal, and possibly swell tests to evaluate clay swell if your clay exhibits significant shrink/swell potential.
