In our neighborhood, a large condo is coming up.
I pass by the site almost everyday, so I've been seeing this and that.
I was impressed with how they get cement up to pour the upper floors.
They use this crane thingy that has a grating attachment.
The cement truck dumps its cement into the grating and the cement is pumped up to the higher floor through the long arm.
The long arm is actually a tube that they also use to disperse the cement to the areas they need to construct.
