The adequacy of available information on these parameters affects importance, mostly because the contractor was not prepared for them. in the bench operation the drilling equipment may have booms which are other safety restrictions productivity The geotechnical investigation should include analyses both for clay The Nowadays it becomes necessary to elaborate an specific model for the management of the geologic risks, that is adapted to the peculiarities of the current development of the building and infrastructure systems; and allow the use of the current tools as the GIS, Wombs . Therefore, construction manager did not follow appropriate procedure that is critical in conducting geotechnical site investigation. Construction Impact Stand-up time, particularly in blocky ground, dictates in large part whether ground support systems such as rock bolts and mesh are required, or other systems such as steel supports or shotcrete. For certain soil samples, additional tests may be performed to determine moisture content, unit weight, unconfined compression, and other factors. rock on a sustained basis.

Planning is very important when it comes to construction of giant buildings because the structure and stability of the building must be mapped out before it is built. In order to ensure proper support for bridges and other associated structures, it is generally necessary for contractors and other construction managers to engage a geotechnical engineer to make a complete foundation investigation of the proposed foundation.
