Case Studies

Case studies are well known as valuable teaching tools. Our intent for these case studies  is to provide you with a better understanding of what we do and how we approach typical projects at MEE. Each case study is taken from from our files and has been edited to present a more casual writing style than our formal reports, but generally follows the structure of our reports and gives an overview of the findings and conclusions from an investigation.
