DESCRIPTION:The aim of the research is to identify a practical methodology
  for quantification of environmental impacts due to geotechnical infrastru
 ctures. The idea is to compare the quantifiable environmental impacts of c
 onstruction solutions designed according to the same specification for a r
 ange of geotechnical structures\; through which a short list of representa
 tive environmental impact indicators is then identified. The properties of
  these indicators should be easy to understand and use. \n\nAn indicator t
 he research is paying particular attention to is embodied energy\, this is
  the total energy that is attributed to bringing an object to its existing
  state. Embodied energy and Life Cycle Analysis (LCA) case studies were ca
 rried out – on retaining walls\, foundation designs and the on a compari
 son between the slabtracks and conventional ballasted embankment design. A
 t this stage\, we find that there are strong correlations between embodied
  energy and the values of more established indicators such as CO2 emission
  and Eco-Indicators etc for geotechnical infrastructures. It is thus evide
 nt that embodied energy is one of the meaningful impact indicators. \n
