Reconstruction of a Pier in Boston, Massachusetts, Harbor
The reconstruction of the outer parts of a large ocean pier, the wooden pile foundations of which had been seriously damaged by marine borers, is described in this paper. The wooden piles were removed and steel bearing piles many of which had a length in excess of 100 ft were substituted. These are believed to be the longest steel bearing piles ever used. They were driven by steam hammer through fill and blue clay to a bearing on bed-rock, or the hard material immediately overlying it. The piles were placed in groups of four with the upper ends protected by steel cylindrical caissons filled with concrete.
For the most part, the concrete deck of the old structure and its supporting concrete beams were removed and replaced by a new concrete deck supported on steel beams and girders. A test was made on a pile having a length of i37 ft, and the complete data of the test are given. As far as the writer is aware no other test on a pile of this length has been reported previously.
The use, in certain parts of the pier, of a light-weight concrete to protect the wooden piles from further damage is also described.
