To construct excellent project, the condition of the project site including subsurface and surface condition must be investigated and assessed thoroughly.
Site assessment may involve determining the present and installation of underground services, specify suitable foundation depend on recommendation of geo-technical report, anticipate the level of ground water, grading amount needed for proper drainage to push water away from the structure, whether the site is difficult to excavate or not, frost penetration depth.
To build the structure as per the design, estimate the excavation volume accurately, and provide suitable drainage, structural elevations and layout must be carried out with substantial precision.
