ON-BLOCK GmbH consists of highly experienced and motivated consultants specialised in Airport Operations Support. Our core competence is the realisation of ORAT - Operational Readiness & Airport Transfer, which is the most effective process to ensure a successful start of operations of new airport infrastructure. Based in Deutschfeistritz, Styria, Austria, we deliver our services around the world to the international airport industry. ON-BLOCK GmbH was founded by Reinhard Zeiler in the beginning of 2013, with the main target to provide ORAT expertise for the implementation of new airport facilities worldwide. Reinhard has gained the required know how for this complex task in leading many ORAT projects around the globe over the last thirty years. In January 2021 Christoph Aumüller joined the company‘s management as Chief Operating Officer after having accomplished several successful projects together with ON-BLOCK in the previous years. Since April 2022, the company family has had one more member, when Leander Gottschalk was hired as a Project Manager.
