Carmichael Engineering, Inc., has multiple drilling rigs and crews to support our Geotechnical Engineering Services and also provides contract geotechnical drilling and sampling services.  Operating our own drilling equipment assures consistency and quality in our geotechnical explorations to provide our engineers the best information.  Also, operating our own drilling equipment allows us greater flexibility in scheduling field services. We are able to respond on short notice and can meet almost any reasonable schedule.  We operate both truck mounted and ATV mounted drilling equipment for access to difficult sites.
