Bentley Infrastructure 500 [1] is a ranking of infrastructure owners compiled by the CAD software company Bentley Systems. It was first published in 2010. The index ranks the combined infrastructure assets in the hands of the biggest public and private organisations.
In contrast to the Forbes Global 2000 ranking, the Bentley Infrastructure 500 ranks companies according to their reported tangible fixed assets (or other comparable noncurrent physical assets such as buildings or fixed structures, land, and machinery) - and is a direct measure of the infrastructure owned and operated by an organization. The aim of the ranking is to help global constituents appreciate and explore the magnitude of investment in infrastructure and the potential to continually increase the return on that investment. The Infrastructure 500 index also takes into consideration governments and states.
