Eislingen/Fils, January 16, 2026 – Salvia Gebäudetechnik continues its strategic growth trajectory and is purposefully expanding its planning expertise: the engineering firm Hetzel, Tor-Westen + Partner Ingenieurgesellschaft mbH & Co. KG (HTW Ingenieure) is becoming part of the Salvia Group.

HTW Ingenieure will operate as an independent company within the Salvia Group. The existing locations, teams, and responsibilities will remain unchanged. The independence of HTW is a key element of the partnership and ensures that clients will continue to receive neutral, objective planning services that are fully dedicated to their projects.

By integrating HTW Ingenieure, Salvia is systematically expanding its planning division and complementing its existing portfolio with additional engineering and consulting expertise. The collaboration particularly strengthens the ability to comprehensively support technically demanding projects across all service phases.

HTW Ingenieure has stood for high technical competence, interdisciplinary thinking, and the successful realization of demanding building services projects for many years. The company has earned an excellent reputation, especially for technically and architecturally complex construction projects.

“With HTW Ingenieure, we are gaining a strong, well-established partner with a high level of planning expertise and an excellent project track record,” says Filippo Salvia, Managing Director of the Salvia Group. “Our approach is to preserve proven structures while leveraging the advantages of a strong group – for the benefit of our customers and employees,” adds Dirk Jannausch, Managing Director of the Salvia Group.

The partnership is also viewed at HTW Ingenieure as a consistent step toward the future:

“Joining the Salvia Group opens up new opportunities for us in project implementation, knowledge sharing, and the further development of our organization,” say Karsten Miltkau and Sven Kamprüwen, Managing Partners of HTW Ingenieure. “At the same time, we will continue to operate as the same team and company – with a clear identity and a strong focus on our clients.”

Through this partnership, Salvia Gebäudetechnik underscores its commitment to further developing planning expertise, technological depth, and implementation strength within the group – while maintaining entrepreneurial independence.
