By Luke Carothers  The built environment is movement.  Steel rises.  Concrete cures.  Sits transform day by day.  Yet, for much of the AEC industry’s history, those transformations have been documented through static photos, written reports, and milestone presentations that struggle to capture the real energy of what is happening on a job site.  Drone video is changing that.  The 2025 Marketing Excellence Awards Drone Video category highlights how AEC firms are using aerial storytelling to show projects in motion.  Instead of explaining progress, firms are now about to show it, which reveals scale, complexity, and momentum in ways that resonate with clients, communities, and future talent.  This year’s top three campaigns from Gilbert Architects, McKim & Creed, and Baxter & Woodman, demonstrate that drone technology is more than a cinematic tool.  It is becoming a powerful way to communicate expertise, document...
