Modern building tools take a big part in structures today, take the the excavator, for example.

If we didn’t have the excavator, then it would take a lot longer to build houses, because the first step is to dig the basement. But since the excavator was built, now it takes no time at all.

Let’s look at the crane. If we didn’t have the crane around, it would take much longer to make office buildings, and skyscrapers, and two story houses.

If we didn’t have the wrecking ball, It would take quite awhile to take down buildings, and fountains, to put something else there.

Or if we didn’t have earth movers, then how would we level out hills and valleys to put malls, or neighborhoods down?

Also, the cement mixer. The cement mixer plays a pretty critical part of building, because we need cement, to actually build things.
