Nine international teams from CHILE, THE NETHERLANDS, INDIA, UNITED KINGDOM, FINLAND, JAPAN, SINGAPORE and the USA took part in BLL2009 to design a scheme consisting of 2,500 hotel rooms, 500,000 m2 of office space, 50,000 m2 of shopping and 2000 new homes. An international collaboration on this scale with these time constraints has not been attempted previously, and BLL showed how BIM brings the processes required to manage large multi-stakeholder projects.


With so many people and companies producing so much data from different locations, cities and time zones around the world, a project portal was the only way that the event could be managed. Each team was allocated a structured work-space in the Asite Portal where the models and calculations from the various disciplines were stored and managed for revisions etc. A colossal amount of information in the form of models, drawings, AVI's, PDF's, jpegs and many other documents were uploaded to the portal where they were distributed to the project team and judges. Asite brought efficiencies to the process so that everyone involved was able to find, view and download the data they needed within the 48 hours.


More than 150 companies & consultants participated in Build LONDON Live at the same time. These ranged from sizeable architectural practices to individual consultants specialising in M&E and visualisations. Some of the organisations are established experts in the BIM sector; others were students from universities in Finland and the USA.


Not only were there teams from nine different countries, but many of the teams were internationally based with architects, engineers and modellers all working from different locations. Co-location is not essential. Team 3DMB consisted of 13 individuals from nine companies who worked from ten different locations in four countries. Build LONDON Live proved that collaborative working is possible wherever the participants are located.


Build LONDON Live showed how it is possible for large groups of people to effectively collaborate and communicate on-line. The schemes submitted during the 48 hours included designs of enormous complexity which required a high degree of collaboration. This was achieved using email, Skype, GoToMeeting and Asite. BIM tools and various design review applications allowed for intricate communication in a difficult engineering environment. The event took place at the same time as the 2009 Copenhagen Climate Conference. It showed that how large groups of people can work together and achieves impressive results with a negligible carbon footprint.
