An environment to encourage the best

“We all want our company to win, and I’m not just talking about winning Grands Prix. To win we need highly motivated, dedicated people, and such people can only exist if you provide them with an environment in which they can aspire to be the best. Great facilities attract great people, and that’s where the story of this project has its roots,” said Group chairman and chief executive officer . And the UK’s Arena magazine recently placed the Technology Centre as one of the “45 greatest buildings in the world”. Set in 50 hectare, landscaped grounds, it has office space of 57,000 m2 and will house 1000 people when all of the previous 18 locally dispersed McLaren activities centralise here. On site are McLaren Racing, McLaren Automotive (including Cars and Composites divisions), McLaren Electronics, McLaren Marketing, and Absolute Taste – the latter provides the onsite catering facilities (see later). A new company, McLaren Applied Technologies, is being established to offer wider access to Group technology. 2 Kimi Raikkonen in the new Viewed from the air, the kidney shape building and its adjacent 17,000 m McLaren MP4-19,Valencia lake form a circle. Inside, a main boulevard is separated from the lake by a glass façade (see 5-axis Integrex machine,for example. picture, below and left). Above this main boulevard at first-floor level is an “Our parts are becoming more elevated walkway and along which are the various companies’ reception desks.

The machines can not only tackle new,more complex parts but also reduce operations on existing ones.“A good example of this is a front axle. Predominantly titanium,it would have been turned on a lathe before moving onto a machining centre to have features such as hole facets,drive pegs and other holes for securing parts to it produced,for example. On an Integrex we can now complete all the operations on one machine,leaving just the grinding of bearing journals. But,arguably,it is possible for the Integrex to do that too,”Mr Ching offers.

Wacky facts

❐ To confirm that the building’s glazed façade would remain in place in strong winds, a jet was used offsite to direct a blast of air at it; ❐ Partitions can be sheer glass up to 4.2 m in height. They do not move even when doors are opened and closed; ❐ The 12 m ‘windblades’ that support the glass façade fronting the lake, and which also run between the vertical columns supporting the roof, are modelled on the rear wing support struts of the 1995 Le Mans 24 Hours-winning McLaren F1 sportscar; ❐ Because of their size, these blades were manufactured using the expertise of Team McLaren Mercedes Technology Partner BAE Systems in similar manner to Airbus wing frames; ❐ Due to building height restrictions – no more than 11 m above ground - no chimney to vent engine exhaust could be built, so an air column 3 m in height transports fumes into the air at high speed; ❐ The lake is a receptacle for water used for wind tunnel cooling purposes (6000 litres/min). The water returning to the lake is aerated over ‘falls’, while the water level is kept constant by a feeder lake. It overspills into three other lakes each featuring a different type of algae. When the water ultimately finds its way into the nearby Bourne river it is cleaner than rain water; ❐ Customers collecting their $500,000 Mercedes-Benz SLR McLaren (5.4 litre, V8, 760 Nm torque, 450 kW output) will drive it around the main lake so that, viewed from the main boulevard, it appears to be travelling across the surface of the lake.
