Geotechnical Engineering

For over 30 years, The Quill Group has been conducting subsurface/foundation investigation analysis and design, test borings, pile design, retaining wall systems, dewatering systems, Support of Excavation (SOE) and other geotechnical-related services. Full service engineering includes testing, certifications, load testing, pile analysis, monitoring with our in-house equipment and engineers.  Subsurface investigations save thousands of dollars in design and re-design costs as well as project scheduling errors due to unforseen subterranian issues.

Our proven experience in private, commercial, industrial and governmental sectors allows us to assist our clients in obtaining appropriate permits as required by state and local governments. We approach each job objectively and recommend design solutions that fit the client's needs while considering the individual challenges of each site.
