Wow. NYC's intesnity is something else. Workers there work like there is no tomorrow.
I've once watched workers retarring a New York street. Now NYC streets are often pretty awful - covered in steel plating and cones over sewers. But watching the workers retarring a street is poetry in high gear. They move in en masse. Any parked cars that are not moved are lifted and put on the sidewalk - nothing stops the machine.
New Yorkers also talk the game constantly. The workers shout aggressively as though there is no one more important.
Watching this episode on Discovery, shows just that kind of experience. Water workers excavating at night to join buildings to the grid so as not to knock out the water supply. Layered concrete below the tarmac to protect the piping. And all done at frentic pace and high audio volume. You can quite imagine the shift boss getting an ulcer from the stress.
If only our workers could see this. Man. They've been working on the water in my suburb for 3 months! And Joburg's road quality problems are now the stuff of legend.
