Construction topographic survey:
Construction topographic survey, also known as topographic survey, is a research activity to evaluate the natural conditions on the ground at the proposed construction site to serve planning, design, and calculations. volume of excavation and embankment works. In addition, for important projects, during the construction and operation of the project, it is also necessary to monitor settlement and tilt displacements to assess the level of stability and take timely corrective measures if limits are exceeded. allow.
Hydrogeological surveys:
Hydrogeological surveys aim to clarify the distribution rules, physical properties and chemical composition, dynamics and dynamics of underground water.
Hydrogeological surveys are the collection of information necessary to enable the design of groundwater lowering systems. Do a good job of planning and executing field surveys, along with the methods used for drilling, exploration, testing… The next step is to analyze the data collected during the process. field survey.
Successful design of such projects depends heavily on realistic estimates of the permeability coefficients of the various layers of soil and rock present beneath the construction site. The methods of testing permeability coefficients, their scope of application, and their relative values and limits are very complex.
