JE Dunn + Trimble // Part 3: Smart Sustainability

At JE Dunn, sustainability is built into every process. Data-driven decisions, early coordination, and seamless workflows help teams reduce waste, prevent rework, and protect the planet while delivering results. “We’ve embraced Trimble end-to-end and it’s changed everything,” said John Jacobs on stage at Dimensions 2025 (see the fireside chat here: https://youtu.be/PS0gfugxgro?si=KB2Q23ORpLwpb4S4). “We’re doing modeling in Tekla, we’re bringing it all together in Trimble Connect, we’re doing layout in FieldLink, and AR and quality control with SiteVision. We deploy that integrated platform on every single self-perform job that JE Dunn does.” This consistency leads to smart, predictable sustainability and waste reduction. From design to delivery, every team operates from the same proven playbook, data, and tech stack, whether constructing Austin’s tallest skyscraper or a cutting-edge research center in Kansas City . And process is driving performance the first time—before the concrete sets. Results: - Actual concrete requirements were 14% and 32% lower than originally estimated for the two phases of a recent 8,000-cubic yard pour. - On a hyperscale data center, integrated modeling and layout workflows helped quadruple turnover speed. - On another large project, model-to-machine workflows and automated layout cut excavation times by 50% and the corresponding employee hours for excavation by 75%. - In just four years, standardized self-perform workflows have already had an acute financial impact. Rework associated with concrete layout declined from $2.1 million in 2022 to $500,000 in 2024. For 2025 year-to-date, the rework cost is zero. “That’s technology driving material savings, labor savings, then add-ons like trucking that concrete to the job,” Jacobs explained, adding these results compound exponentially across hundreds, if not thousands, of pours on jobsites nationwide. Beyond the economic benefit, there’s a sustainability side as well, according to Jacobs, who pointed out that concrete is responsible for the biggest portion of the company’s carbon footprint.
