Over the course of more than 175,000 projects, WJE engineers, architects, and materials have worked to extend the life of countless structures, improve our understanding of why materials and structures fail, and contribute to a safer and more durable built world. We’re passionate about our work and believe it is our responsibility to share our experiences and lessons learned for the enrichment of our clients and the advancement of our industry.
We hope you learn something new that helps you better understand and address a challenge you face in your own work.
