Can Robots Actually Dig Dirt? | The Reality of Autonomous Excavators and Field Buy-In with Rachael Ferrera
Most construction robotics look great in a controlled pitch deck, but put them on an active highway project with unpredictable conditions and the illusion quickly falls apart. Real jobsite autonomy isn't about replacing the workforce; it’s about unlocking capacity in an industry where 40% of the labor pool is retiring within the next five years. In this episode of Wired to Build , host Nick Caravella sits down with Rachael Ferrera , Manager of Investments and Ideation at Zachry Corporation . A civil engineer who spent nearly two decades inside Zachry moving through estimating, enterprise ERP overhauls, and corporate document management, Rachael now connects heavy civil operations with emerging technologies and strategic investments. Rachael reveals the story of Zachry's deployment of Bedrock Robotics' autonomous excavators—moving from an initial panel meeting to executed agreements and hardware installation on an active machine in under a week. She breaks down why autonomy requires a fundamental shift away from prescribed "Roomba-style" site automation toward true machine learning, LiDAR processing, and Waymo-grade engineering capable of handling complex interactions between autonomous machines and human crews. We also explore the operational realities of introducing frontier tech to boots-on-the-ground operators. Rachael details why field buy-in cannot be achieved through top-down mandates, sharing how sitting in pickup trucks with skeptical foremen, actively listening to survey teams, and creating rapid feedback loops is the true secret sauce to preventing pilot fatigue and building tech that actually survives the jobsite. This is Part 2 of a 2-part conversation. If you missed our breakdown of Zachry’s internal systems, operational overhauls, and early-stage startup alignment, make sure to catch Part 1.
