Setting Standards for 100 Years
Founded in 1898, Twining has built a distinguished history and reputation for excellence. The firm has evolved over the past century and now has over two hundred cross-certified field personnel, a panel of experts who are nationally recognized as authorities on their respective construction materials and a network of sophisticated laboratories throughout the United States. Over the years we have provided sound engineering, testing and inspection for many of the region’s landmark projects. We are not, however, content to rest on our past success. Rather, we are committed to driving the industry forward by writing the guidelines and regulations that will become industry standard, by recognizing and responding to social issues that will transform the industry and by identifying and contributing to the development of emerging materials and new technologies.
