“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.
