One of the most significant challenges facing any design team today is how to map the underground environment with the same Standard of Care and precision as the above ground built environment. Our own Michael A. Twohig will be hosting a workshop at the New Hampshire Land Surveyors Association Annual Meeting as a subject matter expert on the topic of subsurface utility mapping. He’ll speak on Friday, December 7 from 2:00 PM – 4:00 PM.
