The Direction Technique (DT) was responsible for the operational tasks related to the planning, organisation and implementation of the architectural constructions of the National Exhibition.

The Direction Technique, Security and Logistics was set up in 1997. Over the years, its areas of responsibility have changed. In the beginning, they included architecture, infrastructure, legal processes, procedures, transport on the three lakes, security and logistics. Certain areas of activity were later transferred to other directorates: navigation, safety and logistics became the responsibility of the Direction Exploitation in 2001. Legal services and publications were placed under the Direction Générale. The areas of public spaces and the environment were integrated into the Directorate of Technology, Safety and Logistics, which was called the Direction Technique from 1999.
