## Summary

The numbering system can be unfrozen at any time. However, when the numbering is unfrozen, the system will renumber all constructions consecutively in intervals of ten.

Unfreezing should not be carried out without some consideration being given as to the effect on annotations already placed on drawings and cross referencing between constructions within the schedule.

## Resolution

To unfreeze the numbering system:

•     Open the appropriate schedule of work
•     Select Tools > Document Numbering

•     From the Construction Numbering list box un-tick Freeze construction numbering within this document and click OK
•     A dialogue box will appear warning of the consequences of renumbering.  Click Yes to proceed

•     The constructions will be renumbered.
