1-4.1.2.2
Facilities in which alteration, modernization, rehabilitation, and
renovation work is less than 50% of the replacement value of the building, the
building must comply with the criteria in this UFC for new construction, to the
maximum extent practical. All new work accomplished as part of alteration,
modernization, modification, rehabilitation, and renovation actions/projects must
meet the requirements for new construction.
1-4.1.3
Sustainment and Restoration. New work accomplished in
facilities as part of repair, restoration, and sustainment actions/projects must
meet the requirements for new construction in this UFC.
Note: Sustainment and restoration efforts should look beyond the scope
of work to ensure that the fire protection (including life safety) features are not
being compromised or designed only for the portion of the building that is being
repaired. The repair project, if possible, should include a basis to support the
entire building, i.e., if considering providing a fire alarm extender panel to the
existing antiquated fire alarm control panel, ensure the panel being provided has
the capability to support the entire building so any additional projects can utilize
the new panel without having to remove what was just installed.
1-4.1.4
Conversion of Use/Change of Occupancy.
1-4.1.4.1
When any portion of a building is modified from its current use to
that of an inhabited building, billeting, or a primary gathering building for one year
or more, the building must meet the requirements for new construction.
Note: Examples would include a warehouse (uninhabited) being
converted to administrative (inhabited) use; an inhabited administrative
building being converted to a primary gathering building or billeting; or an
non-compliant primary gathering building/billeting being altered,
modernized, modified, rehabilitated, or renovated and converted to
billeting/primary gathering building. Definitions of inhabited, uninhabited,
primary gather building and billeting are found in UFC 4-010-01 DoD
MINIMUM ANTITERRORISM STANDARDS FOR BUILDINGS.
1-4.1.4.2
When any portion of a building is modified from its current use to
that of a mission essential building for one year or more, the building must meet
the requirements for new construction.
Note: Examples would include a warehouse being converted to an aircraft
hangar.
1-4.1.4.3
When any portion of a building is modified from its current use to
any other occupancy use for two years or more, the building must meet the
requirements for new construction. Changing groups of occupants within the
occupancy classification does not constitute an occupancy change.
