Concrete foundation in water
What is the optimum design for the concrete foundation to be poured for 2 storey wooden building (3,5x3,5m - 6m tall). Ground is sand and ground water is at 40cm. The building has 6 posts that sit on 8 outer concrete foundation and 1 central one.
Comment: It would be useful to know: how much water level varies (including flood condition that may apply) and what technology is available locally to install foundations into the ground (e.g. piled suppports)
