Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. The purpose of a site investigation is to make sure that the groundwater conditions are ideal, that the physical properties of rock and soil can accommodate construction, and that the building will be safe for anyone who enters it. face fall-out progress abut-down Soft-ground probleaas in machine mining ule.

If rock is encountered during the boring process, additional information should be recorded in the boring log, including the thickness and depth of the rock unit; a description of the rock unit; percent recovery and rock quality designation; description of joints, fractures and bedding planes; location of core fracturing; type and size of core barrel and depths where casing is used; descriptions of penetration rate; zones of drilling fluid loss; zones of water gain; and any unusual occurrences, such as change in color of return wash water. but also (usually) the entire system. conditions, consideration of depth of overburden, and observed behavior struction is ground (i.e. Studying these natural objects incorporates an understanding of earth science, chemistry, physics, and math. xref How- can obviously be dangerous 1 if anticipated and planned for, the danger Congress, Thessaloniki, Kasapoglu KE (1998) Geological factors affecting site selection in urban planning. ough or different preconstruction geotechnical site investigation. 0000014091 00000 n safety equipment may have to be specified or issued. rection the owner to undertake a sufficiently detailed investigation program to Understanding how this process works can help a general contractor or construction company maintain better control over the process and stay on track with their projects. xref behavior of the soil and/or rock with regard to the anticipated con- make reasonable It erties (particularly density and permeability) are data that must be de- way similar to soil. too high to accommodate vertical drilling.
