Janney Technical Center


"Our extensive in-house laboratory facilities, vast experience, and capabilities set us apart from other firms. We're able to bring innovative testing and analytical solutions to each WJE project."

— John Pearson, Principal and Laboratory Manager

Our Janney Technical Center (JTC) is named after WJE founder Jack Janney. Composed of both engineers and materials scientists, the JTC provides advanced testing and forensic capabilities to solve the most technically challenging problems related to structures, construction materials, and manufactured components. After half a century and more than 175,000 assignments, JTC engineers and materials scientists have successfully completed investigative, testing, and repair projects involving virtually every type of construction material, structural system, and architectural component.

The JTC’s 70,000-square-foot state-of-the-art testing and applied research facility includes a full array of chemistry, petrography, metallurgy, concrete and mortar, corrosion, and structural testing laboratories as well as environmental exposure chambers.

JTC personnel are recognized leaders in their fields and are active participants in standards development and industry organizations. Our multidisciplinary team of experienced engineers and materials scientists enables us to offer extensive testing and investigation capabilities to characterize materials, determine root causes of problems, and evaluate performance. The JTC performs tests to determine specification compliance, simulate performance under field conditions, understand failure mechanisms, generate fundamental engineering properties, and assess service life to meet the needs of various types of clients. Our services extend beyond our laboratories, and it is common for JTC personnel to take our expertise to the field and conduct specialized testing on-site.

From the laboratory to the job site, from engineering to chemistry to physical sciences, JTC professionals develop and test new approaches and create innovative solutions for the built world.
