The soil is the most important yet most neglected in a construction project. All structures, buildings, roads, bridges, dams and even life itself is based on the soil. The soil is the natural foundation that supports all structures and investment. Most clients see soil investigation as a waste of fund despite being the cheapest in the construction process, hardly is the cost of soil test up to one percent of the cost of construction. Some contractors too, ignore the importance of proper soil investigation and analysis and base their design on assumed bearing capacity and rate of settlement.
Soil test helps to determine varying physical and chemical characteristic of soil, which can vary from place to place and from layer to layer even within the limits of the proposed structure.
