Deep soil mixing, structural foundation and earth retention work was performed to support the temporary railroad track and to create permanent foundations and walls for the roadway grade separation. More than 5,600 lf (1,707 lm) of deep soil mixing, 15,600 lf (4,755 lm) of secant pile walls and 2,600 strand tiebacks were installed. 89 Comprehensive QA/QC Integrity Testing Using Thermal Integrity Profiler Brad W. Taylor The Thermal Integrity Profiler (TIP) method uses heat generated by the curing cement to assess the integrity or quality of a cast-in-place reinforced concrete foundation. Thermal measurements are used to estimate the actual shape of the shaft and can be compared with concreting logs to assess the overall quality of the shaft.
