There was tremendous pressure to get the sports facilities finished in time; many projects were started late. Moreover, the games posed enormous challenges for the infrastructure of the Greek metropolis. Roads and subways were extended and modernized. Even the ancient monuments of the Acropolis were restored in honor of the Olympics.
Siemens was involved in the radical modernization of the infrastructure, with its Building Technologies (SBT) providing control solutions for practically all the sports stadiums and venues. In addition, the company supplied state-of-the-art technology - power supply and distribution equipment, traffic guidance systems, mobile phone networks, railroad systems, and a call center with software developed specifically for the Olympic Games.
