Dr. Abdelhamid has been designated as an expert witness for many litigated cases. Dr. Abdelhamid is heavily involved in performing forensic geotechnical and geophysical investigations for several problematic foundations, pavements, retaining walls and slopes. He devises protocols for geotechnical and geophysical testing, in-situ long-term monitoring, lab testing and analysis. He is also heavily involved in preparing and reviewing proposals and expert reports for geotechnical exploration and litigated and non-litigated forensic projects. Dr. Abdelhamid is responsible for meeting clients during the proposal phase, the investigation phase and after releasing the final report to ensure client satisfaction. Dr. Abdelhamid has performed work at wide variety of forensic projects. He evaluated numerous residential buildings from single family house to a whole subdivision. Dr. Abdelhamid also evaluated many commercial, school, hospital, garage buildings. He performed stability analysis for v...
