DVGI October 2019 Dinner Meeting: "Philly Load Test Delivers Knockout Punch" (1 PDH)

Tuesday, October 15, 2019 - 5:30pm

This presentation, entitled “Philly Load Test Delivers Knockout Punch”, will show the drilled shaft load test design and execution results that more than doubled the allowable drilled shaft end bearing value to 200 ksf. in the Wissahickon Formation. Historically, the differentially weathered character of this rock mass results in the assignment of low allowable end bearing values of 50 to 60 ksf. Experience has shown us that most load tests on drilled shafts are only a “proof” test confirming conservative design values. For a load test to maximize geotechnical success, “failure” is the best option. The irony in that truth is clearly quantified in the results of The Philly Knockout Punch load test.
