There's the foreman shouting his orders. The little doozer on the left is his daughter, she's a little too young to be there really and especially so high up, but she so wanted to see her dad at work, and now she is a little worried about the doozer dangling from the crane.
Standing on the bottom, from left to right, you have a doozer with a hammer busy doing what doozers do, two doozers carrying doozer sticks to the construction site being stewarded by a third and a little chap with a screwdriver minding his own business.
And let's just leave you with a close up of the foreman's daughter. Look, she's got oversized boots on, she's so little!
