This piling was all fabricated before shipment, the necessary reinforcing rods, special piling, etc., being ied from Buffalo. In carrying ou1 the construction iii Treadwell, il q] departure from the original plans was thai the ii was to sel up rerticaHi around a drn ing the entire 16 piles, comprising the caisson, as shown in. DRIVING THE SHEET-PILE FOUNDATION the accompanying illustrations. When thus set up thepiling was driven a shorl distance, driving on one ortwo bars at a time, continuing this driving around theperimeter of the caisson until all the piles were drivento their final posil From the plans it will he seen that while this is asmall pumphouse, the details of the piling and structuralsteel are rather complex. The piling used was of suffi-cient section to establish the strenj • pumphousewall vertically between the three sets of strui Ibraves and concret< floors, and to enable them to ithe extreme water tide. The 18 ft. of penetration - the rein forced-concrete floor enabled the pumphouse to re- tain it- structure.
