Postscript: Following are descriptions and details for those among us who are interested in how buildings are put together.
Details: Notice the steel reinforcing bars set within the wood forms. The re-bars sit above the stone base upon small metal frames called chairs (first two pictures). The chairs assure that when the concrete is poured into the forms, the concrete will flow around and under the re-bars. Re-bars are used to reinforce the concrete, reducing cracking and improving the distribution of the building loads. In the isolated piers (third picture) the re-bar is criss-crossed and wired together to form a mat which sits on the chairs. Again, the concrete when poured entirely surrounds the steel.
Side note for trivia addicts: For those of you who have traveled to Cape May, New Jersey, you may have seen the remains of the SS Atlantis, a concrete ship just off shore at Sunset Beach. It was one of twelve experimental concrete merchant ships built during the closing days of WWI, when steel was scarce. Eventually, it was decommissioned and was to be used as a break water at the Cape May ferry, but the Atlantis broke loose in a storm and ran aground. This ship was built using steel reinforced (ferro-cement) construction, much like the footing system seen in the photos below.
But sorry, our new building won't float.
