The bauma (International Trade Fair for Construction Machinery, Building Material Machines, Mining Machines, Construction Vehicles and Construction Equipment) is the world's largest trade fair in the construction industry.
The trade fair, which can be visited by anyone, is held every three years on the grounds of the Neue Messe München and lasts for seven days. Its organizer is Messe München.
The first exhibition took place in 1954 as part of the “Baumusterschau” at Theresienhöhe in Munich and was then known as the spring show for construction machinery. 58 exhibitors presented their products on a total gross area of 20,000 m², attracting around 8,000 visitors.
Two years later, the exhibition space had already doubled and the name “bauma”, which is still used today, was introduced. In the early days, the fair was a purely German exhibition. In 1958, the first exhibitors from abroad took part in bauma.
Both German and foreign suppliers of machinery and vehicles for construction and mining exhibit at the fair.
The trade fair basically comprises four sectors. The "All around construction sites" sector includes suppliers of construction vehicles, construction machinery, construction tools, lifting appliances, formwork and scaffoldings.
The exhibition sector "Mining, extraction and processing of raw materials" pools manufacturers of machines for the extraction of raw materials and mining as well as of mineral processing technology.
The "Production of building materials" sector comprises machines and plants for producing concrete, asphalt, clay and similar building materials.
Drive technology, testing, measurement and control technology as well as accessories including services are presented in the "Components and service suppliers" sector. Numerous scale model manufacturers exhibit scale models of the construction equipment.
