Senior Consultant, Robert D. Spaniol

Robert has more than 28 years of experience in the Explosives Engineering industry and has concentrated his efforts for the past 10 years in the field of Blasting Seismology. Robert has a B.S. in Mathematics from the University of the District of Columbia and has completed a substantial amount of coursework, including: a Safe and Cost-Efficient Blasting in Civil Engineering, Mining, and Quarrying course at Purdue University School of Engineering, and the U.S. Department of Labor’s Mine Blasting Safety and Application Seminar.

 

His professional expertise includes blasting in a variety of construction projects and quarries, blast design consulting for quarries, blasting consultation for construction projects, and vibration and noise monitoring and studies.

 

 

 

 

Project Geologist, Eric Maynard

Eric has a Bachelor of Science Degree in Geology from West Virginia University. He has extensive experience in vibration monitoring, and pre-blast/construction surveys and classroom and field training in monitoring of geotechnical instrumentation including seismograph operation, tiltmeter and inclinometer measurements and data interpretation. 

His professional experience includes vibration monitoring of construction activity and blasting, analysis of seismograph data, pre-blast/construction inspection of structures, and public relations.  Mr. Maynard has also been badged and trained for AOA access at IAD.

 


Mr. Bartholomae has over 7 years of blasting and construction seismology experience. He attained a Bachelor of Science degree in Earth Sciences from Penn State University in 1998. During his career he has conducted seismic monitoring and analysis of blasting and construction vibration events. This experience includes the setup and operation of seismographs inside of the active Black Rock Railroad Tunnel for nearby blasting operations, and the monitoring of construction vibrations within feet of historic residential structures for the SR 54 Cut and Cover Tunnel. He has completed over 1,000 pre- and post construction structural surveys, provided public relations and conducted damage claim evaluations. In 2005 he presented a paper on the control of blast vibrations through timing analysis at the 31st Annual Conference on Explosives & Blasting Technique.
