g. Summary--A brief summary of the structure's condition should generally
be included in the report. The summary should identify any significant
problems found and include a brief comment on type of defect and10cation of
the problem on the structure. The reviewer can then refer to appropriate
sections of the inspection report for details.

h. Recommendations--The inspector should list any maintenance or repairs
that are needed to maintain structural integrity, insure public safety,
preserve the investment represented by the culvert, and extend the service
life.

4-2.6 Updating Inventory Records.

The usefulness of information collected during field inspections depends upon
its availability for use. Records must be maintained in an orderly system so
that specific records can be easily located by authorized personnel for
updating or review.

a. Updating Fi1es--The structure files, previously described, should be
used to retain copies of available information on each structure. They should
be updated each time the structure is inspected or maintenance is performed.
After an initial inspection report has been completed, subsequent inspections
will usually not require the same amount of documentation as a new report.
However, all inspections should be recorded even if they are cursory and no
changes were found. When a culvert is significantly modified, a revised
report should be prepared. The original report should be retained but clearly
marked to indicate that it has been superseded by a new report.

b. File Access--The use of computerized inventory records can greatly
improve the speed at which data can be located and retrieved. Even when
culvert inventory records are manually indexed, it is likely that some form of
tabulation or cross indexing will be required. Typical file access
requirements may include access by:
