The BMW factory prior to the construction of the central building existed as three disconnected buildings, each playing an integral part in the production of BMW 3 Series vehicles. These three production buildings were designed in-house by BMW's real estate and facility management group, housing separately the fabrication of raw auto bodies (645,000 square feet (59,900 m2)), the paint shop (270,000 square feet (25,000 m2)), and the final assembly hall (1,075,000 square feet (99,900 m2))[3]. A competition was held for the design of a central building to function as the physical connection of the three units. It also needed to house the administrative and employee needs spaces. Hadid's design took this idea of connectivity and used it to inform every aspect of the new building. It serves as a connection for the assembly process steps and the employees. Designed as a series of overlapping and interconnecting levels and spaces, it blurs the separation between parts of the complex and creates a level ground for both blue and white collar employees, visitors, and the cars.
The building
From a pool of 25 international architects [4], the BMW jury chose the very innovative design of Zaha Hadid as the final piece of the BMW plant in Leipzig, Germany. With no real precedent for her design, Zaha Hadid's Central Building can only be related to the revolutionary and monumental industrial designs of the past including Fiat Lingotto Factory by G. Matté-Trucco and the AEG Turbine Factory in Berlin by Peter Behrens[5]. The BMW Central building is a 270,000-square-foot (25,000 m2) facility that makes up only 250,000 square feet (23,000 m2) of the 540-acre (2.2 km2) campus[6]. Serving 5,500 employees, the building functions as the most important piece of the factory, connecting the three production sheds. Each day, 650 BMW 3 Series sedans[7] pass through the Central Building on an elevated conveyor as they move from one of the three production sheds to the next. Dim blue LED lights highlight the vehicles after each stage, as they exit one of the sheds. These conveyors not only take the vehicles from one production shed to another, but do so directly through all of the functional spaces of the Central Building. The offices, meeting rooms, and public relations facilities[8] are all built around these elevated conveyors, creating an interesting relationship between the employees, the cars, and the public. Not only is the Central Building an office building and public relations center for the factory, it is also a very important piece of the production process at the factory. All of the load-bearing walls, floors, and office levels are made of cast-in-place concrete, while the roof structure is composed of structural steel beams and space frame construction[9]. The facade is clad in simple materials of like corrugated metal, channel glass, and glass curtain walls [10].
