Geo-Characterization of Brownfield Site for Modernization of a Large Industrial Facility

Abstract

A multi-phase subsurface investigation (SI) program was performed to provide geo-characterization of a brownfield site for the modernization of a large industrial facility. During the planning and implementation of the sitewide SI, the following factors were considered:

  1. facility/structure loading, geometry, and function;
  2. site subsurface conditions disclosed by multiple previous SI programs;
  3. field testing methodology,
  4.  new and revised geohazard evaluation criteria; and
  5. funding and schedule constraints.

The focus of this manuscript is on the geotechnical aspects of the site; environmental considerations are not addressed. The adopted SI program planning and implementation approach/philosophy is described, and the work carried out for one specific structure is used for illustration. The benefits of the SI approach in mitigating subsurface risk in a cost effective manner is demonstrated. Lessons learned that could be useful to practitioners confronted with site geo-characterization for large-scale projects are also discussed.
