The piers from below low water to above high water the steel H sections are encased in concrete approximately four feet square. The steel columns above this are also encased in concrete approximately thirty inches in cross section. its bottom surface is crusted with marine growth. six inches of the faces there is bad spauling. The concrete casing at On the underside and bottom Steel below the concrete has a moderate amount of marine growth and there is no sign of excessive corrosion. The edges of the flanges of piling appear to have the original section. Rivet heads are corroded to some extent. This framework supports a platform Il -7
