About Us
Copyright 2015 - Advanced Terra Testing, Inc.
Established in 1984, Advanced Terra Testing, Inc (ATT), is a full-scope, state-of-the-art geotechnical testing laboratory providing advanced capability in soil mechanics, rock mechanics, and geosynthetics testing services. Located in Lakewood, Colorado, just 20 minutes west of Denver. ATT has performed thousands of projects for hundreds of commercial and governmental clients (including major geotechnical programs at several U.S. DOE and DOD sites). ATT has provided geotechnical testing services for projects in all 50 states and numerous foreign countries.

Laboratory Staff


The heart of ATT's ability to provide quality services lies in the experience, dedication, and training of the lab's personnel. ATT maintains an experienced laboratory staff with the full spectrum of technical, project management, report preparation, and administrative expertise necessary to efficiently conduct the laboratory's operations. Cumulatively, our principals and associates have more than 200 years of experience in applied geotechnical testing and have successfully conducted thousands of testing campaigns involving sample preparation, laboratory analysis, and results reporting for tens of thousands of individual samples. In addition to their eminent academic and practical qualifications, each individual must pass training in our rigorous Quality Assurance, sample handling and tracking, standard technical, and Radioactive Materials License procedures. Current OSHA and NICET training is maintained for staff working in functional testing and/or with site access requirements.




Christopher J. Wienecke, co-owner, has over 40 years of experience in geotechnical testing and field exploration, including the design and execution of geotechnical sample collection programs, laboratory testing campaigns, and the interpretation and use of laboratory data. He is active in the development of advanced laboratory techniques, sitting on both the ASTM D 18 (Soil & Rock Mechanics) and D 35 (Geosynthetics) Committees; he also acts as an adjunct instructor at the Colorado School of Mines.


Duke C. Wilson, co-owner, has over 50 years of experience in materials testing, test equipment design and construction, and laboratory setup and operations; he also has had extensive experience in calibration and maintenance of sensor technologies (e.g., temperature, pressure, flow rate) and recording systems. With applied work in fracture mechanics and fatigue and tension testing, he has been responsible for the performance of thousands of geotechnical testing programs.




ATT's formal quality program was established in 1996 and is based on ASME NQA-1, the rigorous quality requirements established for use in the nuclear power industry. The program, implemented with in-process verifications and internal assessments, ensures that work is performed by trained technicians working to both technical and administrative approved procedures.
