ABSTRACT
Human error is defined as a departure from acceptable practice. Errors are an inevitable part of all human activities. They add a considerable degree of uncertainty to design and construction activities. In fact, surveys indicate that it is a dominant cause of structural failures in buildings and bridges. Errors can be categorized according to causes and consequences. Structural reliability is determined by error control. The problem of error control can be approached from two directions: 1) reduce error frequency or 2) minimize consequences. Checking calculations and job inspections are used to control the error quantity. Sensitivity analyses can be performed to identify the severity of consequences.
