I have seen numbers inside the circles and triangles on helipads. Any idea what these numbers represent? They do not coincide with specific buildings as I have seen several buildings with the same numbers on them. They also do not match up to the amount of floor on any building. Any ideas?

It's the weight rating for the helipad. Used usually for rooftop pads, but you might see it on concrete pads as well.
