What we know: Walmart built its sixth next-generation fulfillment center at 10725 Old Federal Road in Carnesville. The 1.5 million-square-foot site combines skilled associates with machine learning and automated systems. This setup streamlines a traditional 12-step manual process down to five steps, enabling workers to double daily customer order fulfillment. The automated retrieval system doubles overall storage capacity, allowing the facility to store up to twice as many unique items compared to a traditional fulfillment center. The high-density storage setup directly boosts expanded access to same-day and next-day shipping for online orders.
