432 ENGINEERING WONDERS OF THE WORLD.
The thinness of the walls (nowhere exceeding
6 inches) and floors and the slenderness of
the columns have enabled the architect to
take the fullest advantage of the space avail-
able. The strength of the floors and columns
is enormous, and gives a very liberal “ factor
of safety.”
Finally, if fire should, attack the inflam-
mable postal matter which will be sorted
in these offices, the actual structure would
suffer a minimum of damage, as the steel rods
upon which it depends for its stiffness could
hardly be affected through their protective
coat of concrete.
In short, the new General Post Office build-
ings afford one of the finest examples of a type
of construction which appears to be capable of
almost indefinite development.
