A variation on the idea of carrying out as much building work as possible in the factory is to bring the factory to the site. Two recent examples are rollforming long sheet cladding and a variation on the readymix theme.
SpeedDeck Building Systems has been selling aluminium and steel secret- fix roofing in the uk for more than 10 years. Some customers are looking for very long continuous sheets: 37m in one example of a shallow-arched roof. Lorries up to 41m are possible, but not for cross-channel transport from the factory in the Netherlands.
SpeedDeck's response has been to package coil-handling and rolling machinery into a lorry-mounted container, providing sheets of 60m and 70 m lengths for two recent projects. The largest to date was for a Royal Mail building in Bristol by Boyes Rees Architects, where 108m long sheets were specified. Here the container was lifted to eaves level and the sheets rolled directly onto the roof.

Hyde Housing is a housing association that has been involved in a range of pioneering sustainability projects. It wanted to use recycled aggregate concrete for a very small-scale project in London, just a 150mm oversite slab. Co-ordinated by Ecological Development as part of a larger eu-supported sustainability project, the concrete mix involved advice on aggregates from bre's Centre for Waste and Recycling. For delivery the project used Mixamate, a firm that batches and mixes concrete at your site using purpose- made trucks, in quantities from 0.5m3 upwards. Small is achievable.
