In preparation for the production of the A330 and the A340, Airbus's partners invested heavily in new facilities. In south-western England, BAe made a £7 million investment in a three-storey technical centre with of floor area at Filton. In northern Wales, BAe also spent £5 million on a new production line at its Broughton wing production plant. In Germany, Messerschmitt-Bölkow-Blohm (MBB) invested DM400 million ($225 million) on manufacturing facilities in the Weser estuary, including at Bremen, Einswarden, Varel, and Hamburg. France saw the biggest investments, with Aérospatiale constructing a new Fr.2.5 billion ($411 million) final-assembly plant adjacent to Toulouse-Blagnac Airport in Colomiers; by November 1988, the pillars for the new "Clément Ader" assembly hall had been erected. The assembly process featured increased automation, such as robots drilling holes and installing fasteners during the wing-to-fuselage mating process.
