A regular visual survey of an inspected outdoor sculpture should be
done to identify changing conditions and problems of deterioration
in a timely fashion, prior to the onset of serious deterioration or
material failure.

Planning Criteria:

Formal inspections should be undertaken every six (6) months,
following the initial assessment (see 05725-01-S for guidance in
planning the initial inspection and assessment of outdoor
sculpture).  In some cases, where workload, limited staff and a
large number of outdoor sculpture prohibit semi-annual inspections,
regular inspections may be conducted on an annual basis.

Inspections on less than an annual basis are substandard.  The
Regional Director should be advised if annual reinspections
(following the initial assessment) are not feasible.  Some
mitigation plan may be necessary to assure that outdoor sculpture
are periodically evaluated to avoid neglect and achieve the
objectives of preventive maintenance.  Such a plan would have to be
based on the significance of the materials involved, as well as
age, exposure, and condition of the outdoor sculpture.


1.   Retrieve and review the assessment report on the outdoor
    sculpture to be inspected.

2.   Following familiarization with the condition of the resource
    at the time of the Initial Assessment and all succeeding Semi-
    Annual Inspections, go into the field and carefully inspect
    all surface areas to determine the nature and extent of
    weathering, deterioration or damage since the last semi-annual

3.   Make notes and list changes in condition.  Photographs (2-3)
    for file are recommended (with dates).

4.   Refer maintenance problems to GSA building manager for
    corrective action.

5.   Refer conditions of deterioration or structural failure which
    are beyond the scope of maintenance to the appropriate
    Regional Historic Preservation Officer and Fine Arts Officer for scheduling an
    evaluation by professionals.
