SUBSOIL EXPLORATION AND SITE INVESTGATION

Before starting of any structure like multistory building or other structure more loaded firstly we have to make subsoil exploration in order to obtain information used in design and construction  of foundation , since  foundation transmit all load from structure to the soil .

Subsoil exploration is the process of obtain soil stratification at a given site or determining the layers of natural the soil deposit that will underlie the proposed structural and their physical property, this process done because engineers need to know information that will help then in determining the nature of soil at the site and its stratification and in Selecting the type and depth of foundation suitable for a given structure.

                                                           nature of the soil at site

Engineers also their need to know information for evaluating the load-bearing capacity of the foundation, information help them in estimating the probable settlement of a structure ,location of ground water table, the depth and nature of bedrock ,investigation of safety of existing structural, suitability of the soil and degree of compaction.

Subsoil exploration of structural are divided in three phase such as Collection of Preliminary Information, Reconnaissance and Site Investigation, this phase of site investigation provide reliable, specific and detail information about the soil and ground water condition of the site, and consist of Planning; making test boreholes; collecting soil samples at desired intervals for visual observation and laboratory tests.

                                   sample of the soil are collected at desired intervals
In determination of the number of boring there is no hard-and-fast rule exists for determining the number of borings are to be advanced. For most buildings, at least one boring at each corner and one at the center should provide a start. Spacing can be increased or decreased, depending on the condition of the subsoil for more information contact RICIltd at bizididace1@gmail.com and one phone +250786321632
