Zona provided MEP and fire protection engineering services for the renovation of The Treasury 1929, a historic downtown Tucson bank transformed into a premier wedding and event venue. The project modernized the building's mechanical, electrical, plumbing, and life safety systems while preserving its historic character including the original bank vaults. Improvements included HVAC upgrades, new electrical distribution and lighting, plumbing enhancements, and a redesigned basement sump pump system to support the building's long-term performance.

Zona provided mechanical, plumbing, and fire protection (MEP) engineering services for Bugen Hall, the first on-campus student housing facility at Cochise College. The new 7,500-square-foot, two-story residence hall includes 23 student suites, study areas, common spaces, and support facilities designed to enhance the student living experience. Zona delivered coordinated building systems that provide occupant comfort, energy efficiency, and long-term reliability, creating a modern residential environment that supports student success and campus life. 

Zona provided MEP engineering services for the renovation and expansion of Mister Car Wash on Speedway Boulevard in Tucson. The project modernized customer spaces, expanded vehicle wash operations, and added 20 vacuum stations while incorporating upgraded HVAC, electrical, plumbing, and water treatment systems. The result is a more efficient, sustainable, and customer-focused facility designed for long-term performance. 

Zona provided the mechanical, electrical, plumbing, and fire protection design for this multi-phased project. The University of Arizona Global Center, Phase 2 project involved heavy renovation of 10,000 sq. ft. of existing administrative offices, meeting spaces, food service areas, common areas, and office space. The renovation included new conference rooms, team rooms and computer labs. 

Zona provided MEP and fire protection engineering services for The Homing Project, a nonprofit housing community serving unhoused individuals. The development includes short-term sleeping units and shared support facilities such as hygiene, laundry, kitchen, library, office, and dining spaces. Coordinated building systems were designed to provide reliable, safe, and comfortable environments that support the organization's mission of helping residents transition toward long-term housing and stability.

This project in downtown Tucson involved a renovation of an existing 2,300 sq. ft. space for the City of Tucson Court.  This renovation created a Juror Selection Room for the court to use in daily activities.

We provided full MEP services to these three dining locations at Loews Ventana Canyon Resort in Tucson, Arizona.  Canyon Club Cafe's casual spot serves modern American cuisine with Southwestern soul and heart-healthy options that are anything but boring. The Vista Barista Coffee Shop features For Five Coffee drinks, specialty teas, power smoothies, and yogurt parfaits, plus fruits, delicious breakfast pastries, and bagels. Bill's Grill is a poolside retreat featuring food and drink for those guests visiting the resort pool.

The High Bay Balloon Mission Integration Lab is located at the UA Tech Park at The Bridges where researchers and students can work on instruments, telescopes, and high-altitude balloon technology to build and test hardware for experiments and missions designed to fly at extremely high altitudes.  The Mission Integration Lab, a tall, hangar-like “high bay,” serves as a test bed for new technology enabling researchers to be able to prepare and test stratospheric balloon payloads. 

This project included the renovation and reconfiguration of the existing, single story 14,000 sq. ft.  clinic and a two-story, 18,000 sq. ft. addition. The facility incorporates integrated care modules for pediatrics and family medicine, OBGYN, Dental, and Behavioral Health. The project contains specialty spaces such as radiology, pharmacy, laboratory, and community programs, including a large multi-purpose room on the second floor with magnificent views of the Catalina Mountains to the north.

The Zona Team provided medium voltage electrical construction design documents and construction administration for this project where Steward Observatory required utility power for their new building at the University of Arizona Science Tech Park Campus.  The Tech Park maintains and owns their medium voltage gear and requested that the firm provide design services to engineer the modification of their existing medium voltage (12,470V) system.  The design included a new liquid filled 12,470V to 480V transformer, two switching cabinets to ensure the existing redundant medium voltage feeds switch properly and medium voltage cable.
