Jacobs was selected to deliver design, engineering and environmental services for Boeing's multi-billion expansion at its St. Louis, Missouri, campus.

Designed to nearly double Boeing's regional manufacturing footprint, the 1.1-million-square-foot expansion will support advanced assembly facilities and the associated post assembly operations center for future generations of advanced aircraft.

Site construction is underway and will be completed in multiple phases between 2026 and 2030.

"During the past two years, our ongoing collaboration with Boeing from design concept through construction and accelerating National Environmental Policy Act approvals in eight months, reflects Jacobs' commitment to supporting national security and defense operations by providing critical facilities and infrastructure," said Executive Vice President Susannah Kerr. "This achievement— including the required demolition of an old facility—demonstrates our experience navigating complex design and environmental challenges."

"The largest investments Boeing is making in defense is in St. Louis," said Vice President of Boeing St. Louis Site Readiness Mark Webb. "The new classified facilities will feature the greatest advancements in digital design and manufacturing the world has seen. Our St. Louis site will continue to grow in facilities and head count for the next several years."

This work reinforces Jacobs' reputation for delivering critical infrastructure, environment, water and energy solutions for Departments of Defense and defense contractors, with environmental compliance, architecture and engineering contracts for the U.S. Navy and U.S. Air Force, and as Construction Manager as Advisor of Fermilab's DUNE Near Site. Jacobs has also supported the Architect of the Capitol, through comprehensive energy and water services for the Library of Congress, coastal resilience solutions for Tyndall Air Force Base and served as construction manager for the Los Angeles Federal Courthouse.
