Site Surveys

A site survey is an inspection of an area where work is proposed, to gather information for a design or an estimate to complete the initial tasks required for an outdoor activity. It can determine a precise location, access, best orientation for the site and the location of obstacles. The type of site survey and the best practices required depend on the nature of the project.

Shiva Consultancy offers site survey which includes geotechnical investigations to obtain information on the physical properties of soil and rock beneath the site. A typical geotechnical engineering project begins with a review of project needs to define the required material properties. Then follows a site investigation of soil, rock, fault distribution and bedrock properties on and below an area of interest to determine their engineering properties including how they will interact with, on or in a proposed construction. Site investigations are needed to gain an understanding of the area in or on which the engineering will take place. Investigations can include the assessment of the risk to humans, property and the environment from natural hazards such as earthquakes, landslides, sinkholes, soil liquefaction, debris flows and rock falls. A geotechnical investigation will include surface exploration and subsurface exploration of a site.

Geophysical exploration

It is used as geotechnical investigations to evaluate a site's behaviour during seismic event.

  • Crosshole method
  • Downhole method (with a seismic CPT or a substitute device)
  • Surface wave reflection or refraction
  • Suspension logging (also known as P-S logging or Oyo logging)
  • Spectral analysis of surface waves (SASW)
  • Modal Analysis of Surface waves (MASW)
  • Reflection microtremor (ReMi)
