This is the second stage of site investigation. When the preliminary investigation program does not provide sufficient information for design and construction of foundation further investigation is required, and this investigation is called detailed site investigation. The preliminary investigation data are used as a basis of locating additional boring and determining additional samples. Types of Detailed Site investigation i) accessible investigation ii) inaccessible investigation. Accessible Investigation Accessible investigation method of soil exploration consists of digging of trial pits and test trenches. They permit a direct inspection of soil and its…

What is preliminary investigation? and what are the purpose of this investigation? this is the first stage of site investigation. The purpose is to provide an engineer a rough idea on the soil conditions at a given site. A preliminary investigation generally consists of: Fact finding survey Reconnaissance Trial boring Fact Finding Survey | Preliminary Investigation In fact finding survey, all the available information on the soil condition near the site and behavior of other structures in the vicinity is digested. The desired information can be obtained from technical journals, published…

What is site investigation? Soil is made by nature and often used for foundation in its natural state. Unlike steel or concrete the properties of soil cannot be controlled and must be used as they exist. As a result the engineers are compelled to control the loading conditions. In order to provide loading conditions that will not exceed the carrying capacity or allowable deformation, the extent and properties of soil must be determined prior to the design of the foundation. The information can only be obtained through a properly planned…
