The Puzzle of BIM
Rather than doing maths puzzles on LinkedIn or Twitter, please take a look at my blog posts. They might answer a little bit of the real BIM puzzle i.e how to make BIM work in practice and to make money.
One answer is 58. (8+6+13+31). As a clue, another answer has to do with the geek classic ‘Hitchhiker’s Guide to the Galaxy’
There might be other answers, I don’t know since I am more of a BIM, design & construction guy and not a mathematician.
