As Managing Principal of AECOM’s Rocky Mountain Buildings + Places practice, I’m proud to lead a team of architects, landscape architects, engineers, and project managers delivering high-impact projects that shape communities and advance critical missions.Our work spans a broad spectrum—from civic and cultural institutions to federal campuses and mission-driven facilities—reflecting the depth and diversity of our talent. I believe that range is one of our greatest strengths: it allows us to remain agile in a dynamic economic landscape and pursue the kind of work that challenges us, inspires us, and makes a difference.With a background rooted in design excellence and a passion for high-performance buildings and integrated project delivery, I’m committed to cultivating strong partnerships, empowering teams, and aligning our work with what matters most to our clients and the communities they serve.Let’s connect if you’re interested in resilient, future-forward design, interdisciplinary collaboration, or learning more about the incredible work happening across the Rocky Mountain Practice.

ABOUT JASON SIELCKEN

As the Chief Architect of GSA’s Rocky Mountain Region, I guide the design direction for all capital investments in Colorado, Utah, Wyoming, Montana, North Dakota, and South Dakota. I\'m responsible for administering the Design Excellence Program, guiding the evaluation and selection of the architects, engineers, and builders working on our projects; leading the design peer reviews and upholding the agency-wide standards for quality throughout all phases of the project. In addition, I lead the Region\'s Planning and Technical Practice, which comprises the Historic Preservation, Fine Arts, Cost & Schedule, and BIM Programs; as well as our Planning and Development Team, responsible for providing technical expertise in the identification and programming phase of our projects. I\'m a nationally recognized expert in design-build delivery, as well as the delivery of cost effective net-zero energy buildings. When I’m not working I can be found traveling with my wife and sons, seeking out and running the best mountain trails Colorado has to offer.
