A multidisciplinary team of engineers, materials scientists, and technicians operates the Janney Technical Center (JTC), providing reliable answers to questions about architectural systems, components (structural, materials, parts), and construction materials. The center encompasses more than 45,000 square feet and is one of America’s largest construction-based testing laboratories. It can accommodate virtually any construction-related testing, metallurgical testing, or research project, from the performance evaluation of a new curtain wall or the fatigue and fracture testing of reinforcing bars to accelerated weathering tests or specialized physical and chemical testing of materials. The JTC’s capabilities range from scanning electron microscopy with 100,000x magnification to full-scale load testing with virtually unlimited capacity in our 8,000-square-foot structural test lab. The JTC also maintains state-of-the-art equipment for field evaluations, structural monitoring, instrumentation, and nondestructive testing for use when we need to diagnose the problem at its source.

To evaluate challenging structures and components, our team goes beyond the routine to develop specialized testing procedures, data collection systems, and equipment. This innovative and unique testing and research has often led to the development of standardized testing methods for construction materials that are commonly used today.
