Optimizing the Design of Driven Pile Foundations with Instrumented Static Load Tests
Peter Narsavage, P.E., Senior Geotechnical Engineer, E.L. Robinson Engineering

Two large bridges over the Great Miami River in Dayton, Ohio, were recently constructed.  The foundations for these bridges consist of driven piles, and the foundation design was optimized for the least cost given the constraints of the site conditions and pile drivability.  Over 40 different possible combinations of pile diameter, pile wall thickness, pile capacity, and pile hammer were considered during design, including open ended piles.  Cost factors included material costs for steel and concrete including length surcharges over 50 ft, crew and equipment time and costs to unload and drive the piles, and time and material costs for splices. Foundation costs were compared on cost/ton basis. The selected pile design was a 16-inch pipe pile with a nominal resistance of 600 kips, which exceeded the state DOT's standard maximum nominal resistance of 450 kips for this size pile. During construction, two instrumented static load tests and many dynamic load tests (PDA with CAPWAP) were performed to evaluate the selected foundation design and the results used to further refine the foundation design.

The objective of the webinar are:
  • Efficient pile design must consider the pile properties, the soil properties, and the pile driving equipment.
  • Foundation systems should be compared based on cost per capacity ($/ton).
  • The results from instrumented static load tests can be used to optimize a pile foundation design.
Upon completion of the webinar program, you will receive up to 2.0 Professional Development Hours (PDH).
