Due Diligence

Due diligence studies are performed for clients prior to purchase of a property.  They provide general geotechnical information for a property that could influence decisions regarding the difficulty and costs of development of a site due to the subsurface conditions encountered.  At the same time, geotechnical concerns and associated risks can be identified and discussed.  This approach serves to further assist the client with pre-purchase information that can help them make long-term planning decisions.  Surface observations are also conducted in order to determine whether there is surface expression of conditions which may cause concern.  Test borings are widely spaced (typically 500 to 1,000 feet apart).  Samples taken during drilling are tested to determine relevant engineering characteristics of the site.  Reports provide descriptions of the engineering concerns, possible types of construction and recommendations for conditions which would need to be evaluated more extensively. 

Due diligence studies typically include the following:

  • Site observations
  • Widely spaced test borings and/or test pits
  • Collection of subsurface data
  • Laboratory testing
  • Engineering analyses
  • Final letter or report detailing geotechnical issues, construction considerations, and associated risks
  • Client meeting to discuss findings and site development alternatives
