How it started
History
BIG was created by law in 1992, with the objective of centralizing property management for Austria's public sector. The federal real-estate property had previously been managed by the Federal Buildings Directorate Vienna (Bundesbaudirektion Wien) in the Vienna province, and in the other provinces by the Federal Buildings Administrations (Bundesgebäudeverwaltungen). The aim was to improve the cost-efficiency of various government departments. The underlying premise for this system of internal rent was that requiring departments to pay for and account for their usage of buildings would force them to rationalise their use of space and allow surplus space to be put to alternative use or sold.
