Geotechnical Expert 519467 MA

Expertise Description

My career has spanned over 45 years in the field of Geotechnical and Underground Construction with expertise in geology, engineering geology, heavy and underground construction, microtunneling, mechanical excavation, and dredging. I have provided geotechnical expert witness services in Massachusetts for more than 40 years. I have additional knowledge in feasibility studies, exploration, geotechnical interpretation, pre-construction evaluation and pre-bid assessment, improvement of TBMs and TBM performance, analysis, assessment, presentation, and adjudication of differing site conditions, and analysis, assessment, and solution of construction difficulties on various types of underground construction.

Areas of Expertise

Consulting Experience

My consulting experience includes working as a Geotechnical and Underground Construction Consultant for numerous clients.

Professional Experiences

My professional experience includes having developed the a series of tests for predicting tunnel boring machine excavation penetration rates and cutter rolling path life. I have developed standards used in the industry for predicting, analyzing, and improving mechanical excavation performance and tunnel excavation efficiency. I have developed analytical methods to assess feasibility, select underground construction equipment, forecast, and evaluate excavation performance, and cutting efficiency, to minimize downtime, delays, difficulties with geotechnical conditions, and improve excavation efficiency. I have developed extensive studies of labor efficiencies, daily progress, and construction coordination to improve construction performance. I have developed analytical techniques for analyzing and understanding rock cominution under difficult conditions and has published a treatise on that subject.
