The commencement of Vastu for a plot is by testing the earth, for the following
• Shape • Colour • Odour • Taste • Hardness • Density • Porosity • Level
When considering a plot the most important factor is the geometric axis. One must make sure that the geometrical axis of the plot should be properly aligned with the axis of the earth’s magnetic field. Lack of alignment makes the plot weak and not quite auspicious. There can be several shape of plots rectangle & square shaped plots are considered auspicious.

Plots close to religious places and factories should be avoided as there may be disturbance, pollution, noise etc. and it’s difficult to have peace of mind in such places. A small plot located between two bigger plots must be avoided as health: wealth and happiness are literally squeezed out of such plots. Extension of plot must be studied carefully as it can lead to either growth or destruction of the owner’s fortune or health.

It is necessary for the safe and economical design of foundations. Soil investigation provides us the information regarding different soil strata lying underneath, seasonal variations in ground water table, depth and composition of the rocky base and other such details.
