Abstract
The Sohio Corporate Headquarters building foundations in Cleveland, Ohio are relatively unique, involving as they do some of the deepest caissons on record, combined with a socket friction design. This paper reports the performance of a full-scale load test and the results of instrumentation programs performed to evaluate the design and performance of 240-ft (73 m) deep rock socket caissons at the Sohio Corporate Headquarters building project. The load test was carried out to 2.5 times the theoretical design capacity and the results are reviewed in terms of both total capacity and the individual design parameters, such as socket friction. Details of the instrumentation program used to evaluate concrete strain and corresponding load transference as a function of applied load, caisson depth, and time are also presented. In addition to the load test, the installation details and results of a production caisson instrumentation program to permit long-term monitoring of concrete stress and strain levels are reviewed.

Caisson Load Test and Instrumentation Program – Sohio Corporate Headquarters
The Sohio Corporate Headquarters building foundations in Cleveland, Ohio are relatively unique, involving as they do some of the deepest caissons on record, combined with a socket friction design. This paper reports the performance of a full-scale load test and the results of instrumentation programs performed to evaluate the design and performance of 240-ft (73 m) deep rock socket caissons at the Sohio Corporate Headquarters building project. The load test was carried out to 2.5 times the theoretical design capacity and the results are reviewed in terms of both total capacity and the individual design parameters, such as socket friction. Details of the instrumentation program used to evaluate concrete strain and corresponding load transference as a function of applied load, caisson depth, and time are also presented. In addition to the load test, the installation details and results of a production caisson instrumentation program to permit long-term monitoring of concrete stress and strain levels are reviewed.
