Re: Summary of Noncovered Work Determinations

The following briefly describes the selected installation activities for
which Davis-Bacon Act exemption was granted by the Department of Energy

Fermilab personnel related to supervision of covered Davis-Bacon work,
to verification of operability, and to commissioning activities are not
specifically listed. Estimates of hours of work required have been
provided by WBS managers and are shown in parentheses. References to
justifications are also included with each activity but are not detailed
here.
