Full service care

From concept to completion, STM Design & Build managed every aspect of the Zenger project. The architectural and structural designs were developed in-house in collaboration with the client. Construction included fireproof FM Global-approved systems and fully insulated wall paneling, ensuring compliance with stringent industry standards. The steel structure was produced at STAWI, and STM oversaw all technical installations and interior finishing.

Process-focused design

The primary goal was to expand Zenger’s storage capacity. By first designing a maximized storage system, STM optimized the building’s shape and size to fit the plot and customer needs. The structural design prioritized an open layout, with strategically placed columns to ensure efficient workflows. Next, the facility’s fire safety systems, including a roof-integrated FM Global-approved sprinkler installation, offer industry-leading protection while maintaining its seamless design.

Future-proof innovation

Sustainability was central to the Zenger project. The facility features a 29.5 kWp solar power installation that powers essential systems, minimizing reliance on external energy sources. Insulated panels, local infrared heating, and Zumtobel LED lighting further enhance energy efficiency. These features ensure that the facility is ready to meet current and future environmental standards.

Trust & safety

STM’s strong partnership with the Zenger family allowed for streamlined communication and rapid decision-making. By entrusting STM with full responsibility, the project was completed within just 8 months, ensuring quality, cost efficiency, and customer satisfaction.
