Wiss, Janney, Elstner Associates

Solutions for the Built World


WJE OverviewFounded more than half a century ago, Wiss, Janney, Elstner Associates, Inc. (WJE), is an interdisciplinary engineering, architecture, and materials science firm specializing in delivering practical, innovative, and technically sound solutions across all areas of new and existing construction.

“Ask the Structure”

Jack Janney’s straightforward advice continues to guide WJE professionals today. As materials, technologies, and structures change, our fundamental philosophy remains the same: developing better solutions based on an accurate diagnosis of each structure’s unique problems. Since 1956, WJE has brought a hands-on technical approach, comprehensive testing capabilities, and an enthusiasm for problem solving to each new project.


We have successfully completed investigative, testing, and repair projects for virtually every type of construction material, structural system, and architectural component. With more than 75,000 completed projects, WJE is positioned to solve even the most challenging problems.
