I met a very interesting man recently at the AEC IT-Leaders Roundtable meeting in New York. His name is Hannes Marais and his company is Kalexo (http://www.kalexo.com/).
During the break at the Roundtable, I took a look at the demo tools provided by Kalexo, and I have to say, I was impressed.
How can I describe their main product, Teamwork? It's kind of a cross between Sharepoint, Buzzsaw, Skype and GoToMeeting, with a dash of Projectwise, a sprinkle of Yousendit.com, a hint of Newforma and a splash of YouTube. Confused? For a detailed look, read Paul Wilkinson's recent blog post: http://www.extranetevolution.com/extranet_evolution/2009/04/a-closer-look-at-kalexo.html
Users can share files, manage tasks, hold video conferences, record screen movies, create screenshots, redline documents, send instant messages and teleconference via VoIP, all within one tool which looks pretty straightforward to use. Teamwork offers a framework for communications, creating an electronic environment through which teams collaborate as easily as if they were physically located in one room.
I think as we progress down the road to BIM, that Kalexo might well become another must-have application for smarter, more efficient project working.
