The photo below is from an Chicago Tribune photo essay about the office of Bill Baker, the Skidmore, Owings and Merrill structural engineer who helped design the Burj Khalifa tower in Dubai, currently the world’s tallest building.
He uses Moleskine notebooks and lead holders instead of pencils. There are more photos at the link, but barely any tantalizing little glimpses of the notebooks themselves. Very disappointing! But it’s still an interesting look at his workspace.
