This book presents an overview of the rules for boring spacing, boring depths requirements along with sampling type and depths as well as its design applications, in the light of the experience accumulated in geotechnical investigation. The topics have been discussed in details. Also the number and type of field tests in soil form survey have been thrashed out her to see the variability of test procedure, apparatus used and their contribution in determining soil properties. The study reveals that there is no hard and fast rule for boring spacing or the depth to which boring are to be advanced. For collecting undisturbed soil sample Shelby tube sampler is suitable and it is a common practice in Bangladesh that Shelby Tube is gently hammered into the soil not employing the jacking system. For field test standard penetration test is very user friendly in context of Bangladesh and is most widely used for its simplicity of apparatus and ease of testing.
