Bi-directional load testing was patented by Dr. Jorj Osterberg and perfected by the staff of the company that grew around the patent, Loadtest Inc. From deriving the theoretical analysis of the “upside-down” data produced by an embedded jack, right down to best practices involved in assembling and installing instrumented rebar cages, Loadtest’s engineers literally wrote the book on bi-directional testing. Let’s not, however, assume that just because the technology is now 25 years old, that there are no more blank pages to be filled in at the back of that book!
The principals/founders of LTC are all veterans of, and significant contributors to, this initial development effort. We believe strongly in continuing to improve the state of the art both through internal R&D as well as by interacting with our peers via publications, conferences and industry associations. We have contributed to numerous journals and conference proceedings (see our list of publications) both as authors and as reviewers. We serve on and chair ASTM committees and working groups which maintain and develop the standards which guide our industry. We firmly believe in contributing to our industry and in making it better.
Disseminating the insights we have gained over the years and helping maintain the highest possible standards of practice are part of our professional ethos and at the heart of our philosophy. In fact, LTC was founded in large part as the expression of our principals’ desire to continue to innovate and improve our chosen specialty of deep foundation testing.
It has been said that imitation is the sincerest form of flattery. At the risk of flattering ourselves, we don’t intend to imitate anyone. But we won’t be surprised if others imitate us. “Philosophy”, literally translated, is the “love of knowledge”. Our philosophy is to not only bring our passion for innovation to every project we undertake, but also to educate our clients, peers and competitors by openly sharing the knowledge we have accumulated, and advancing the state of our art.
