Cost Savings Through Efficient Pile Design: A Comparison of Predicted and Actual Results from the US-301 Test Pile Program

This presentation will focus on The Delaware US-301 corridor project test pile program case study where a test pile program was used to optimize design and provide project cost savings. This project involves construction of a new four lane highway from the Maryland-Delaware line to South of the C and D Canal. The Project involved construction of 29 bridges, several conventional retaining walls, and Mechanically Stabilized Earth (MSE) walls. A design phase test pile program was conducted to assist the design team in selection of the most economical pile type for these structures and the design geotechnical soil resistance.

The following types of piles were evaluated as part of this test program: HP14x73 steel pile, 355 mm square prestressed concrete pile, 355 mm diameter open and closed end pipe piles, and a 355 mm diameter Monotube pile. The variation in the axial capacities and drivability of these pile types will be presented, and the effects of soil set up, relaxation, development of pile plug on the drivability, and long-term capacity of these piles will be compared. Pile capacities predicted using static analysis methods will be compared against the field measured capacities obtained.
