The jobsite is very tight and unloading and storing the pipe created some problems. A crane was brought in for the day to do the unloading and stacking of the pipe. The crane was positioned in the street and the pipe was unloaded directly into the excavation. This generally went well except for a few trucks whose drivers could not seem to find New York City, or had engine trouble or got sick or were abducted by little green men; or was that women?
DFP S-1800 splice rings ready for
The piles were about 80' long on average. The Contractor chose to use the DFP S-1800 splice ring to join pile sections. There are other similar products on the market, but load transfer must be considered. Some products have a ledge or pipe stop that is only 3/8" wide and does not allow the full section of the pile to transfer load to the lower section of pile. In this case the wall thickness of the pipe is .545, the ledge on the 9 5/8" DFP S-1800 is .625. This allows for full load transfer to the lower section of the pile. Additionally the DFP S-1800 splice ring is made with a low alloy steel with a 60 ksi yield strength.
