Project Overview

To support the launch of Phoenix’s first light rail system, Sundt, in a joint venture with Stacy Witbeck, constructed the METRO Maintenance & Storage Facility (MSF)—the critical hub for the entire Valley Metro network. Spanning 35 acres, this complex houses all operations, vehicle assembly, heavy maintenance, and system communications for the entire rail corridor. The centerpiece Maintenance of Equipment building, a 138,000-square-foot, three-level structure, includes full-service repair bays, advanced crane systems, and in-floor hoist technology designed for streamlined train service and assembly.

Construction of the MSF required major civil infrastructure, including 3.7 miles of ballasted track, dual bridge structures, 17,000+ linear feet of storm drains, and extensive underground utilities. The project also featured a 30,000-square-foot Maintenance of Way building and 12,000 square feet dedicated to train cleaning and washing facilities. Delivered under a traditional design-bid-build model, Sundt worked proactively with the newly formed Valley Metro to overcome design, permitting, and coordination challenges, adopting a design-build mindset to accelerate schedules and ensure readiness for the arrival of 50 light rail vehicles.
