Plenty mitigation measures for this, which aren't always obvious at the time ie when school was built, but with benefit of hindsight.
Kingston Dock, in the smelly wee Port, was build on water (back filled with sand). Everton's new stadium the same. Ground condition, irrespective of where in Greenock, isn't the issue, unless it incurred significant cost above another site with more favorable ground conditions, but they're likely few and far between.
It's pie in the sky stuff anyway
