Halcro, Regarding the Romans and their Colosseum ,as you would know with the invention of cement the ancient Romans were able to build structures well beyond the heights of anything else in the world at that time.
Everything about is a marvel of ingenuity.
One last thing, You live in a city where there seems to be constant repairs to your water and sewer system? This is a common problem the world over.
I think most of these engineers that design these systems should have a long look at how the Romans built theirs. Today in Rome ancient sections are still in use with few problems.....A city could not be built nor would survive with out one.
