“Needed a soil investigation and Geotechnical Report fairly quickly as well as construction monitoring for some urgent work. Central Geotechnical Services took care of everything I needed to help expedite the permit process as much as possible, was there monitoring the work and has helped me get permits closed out. I will definitely enlist them on future projects.”
