SUBSURFACE EXPLORATION SERVICES

PRE-CONSTRUCTION CONSULTING ENGINEERING SERVICES

FIELD ENGINEERING, TESTING AND INSPECTION SERVICES

Tai and Associates has performed subsurface exploration and other services on 3000+ projects throughout the southeastern United States, including some of the largest in our area. We specialize in providing site-specific geotechnical engineering services, with an emphasis on buildings. We provide all the regular Geotechnical engineering analyses, usually with special emphases on the unique requirements of each project. However, our services usually do not stop at the submissions of the subsurface exploration reports, but also include follow up services to ensure that the actual design has incorporated the subsoil conditions and the foundation design recommendations. Some of the services we have provided are as follows:

“Soil Mechanics arrived at the borderline between science and art. I use the term “art” to indicate mental processes leading to satisfactory results without the assistance of step-for-step logical reasoning…To acquire competence in the field of earthwork engineering one must live with the soil. One must love it and observe its performance not only in the laboratory but also in the field, to become familiar with those of its manifold properties that are not disclosed by boring records…” – Karl Terzaghi, 1957
