Forensic Geology/Petrography is not a new tool in the construction industry; however, it is generally not a well-known discipline. Observations detailed in this presentation are not typically covered during University geological studies. Most of these skills are learned on the job and do require a minimum of 5 years of experience directly under a Petrographer to earn a Petrographer title. This course will provide the standards followed, typical observations, and a few fun projects. Petrography has proven a beneficial tool in the assessment of concrete and construction stone to aide in engineering and construction applications.
