DEMS Data Archive
Whilst DEMS was previously used to manage the upkeep of the Defence Estate, it is now a legacy system. All DEMS data has been archived and will remain as an archive of all DEMS activities that have been recorded via the DEMS application.
Note legislative requirement: As the DEMS data contains information regarding asbestos, there is a legislative requirement that the information be maintained for a period of 80 years since it was last updated. This means that the DEMS data should not be archived before the year 2095.
The DEMS-ID module enables users and managers within the Capital Facilities Infrastructure (CFI) Branch to efficiently manage and report on major capital facilities projects and contracts. It will continue to operate in a stand-alone environment.
