This report presents the results of seismic evaluation
and cost estimates carried out by the National Institute
of Standards and Technology (NIST) for rehabilitation of
existing buildings owned by the Federal Emergency
Management Agency (FEMA). The seismic evaluation and
rehabilitation cost estimates were carried out in
response to Executive Order 12941, Seismic Safety of
Federally Owned or Leased Buildings. The seismic
evaluation was performed based on ICSSC RP4, Standards
of Seismic Safety for Existing Federally Owned or Leased
Buildings and Commentary, and FEMA 178, NEHRP Handbook
for the Seismic Evaluation of Existing Buildings.
Rehabilitation costs were estimated using FEMA 156 and
157, Typical Costs for Seismic Rehabilitation of
Existing Buildings, Second Edition, Volumes I and 2.
FEMA owns 137 buildings. Of these, 125 buildings are
located in Maryland and Virginia (low seismic regions).
Ten buildings were selected for evaluation, of which
seven are located in Maryland and Virginia, two in
Massachusetts (moderate seismic region), and one in
Washington (high seismic region). All sites where the 10
buildings are located were visited by the NIST team.
None of these buildings has a complete set of
architectural and structural drawings, particularly old
buildings such as those at the Emmittsburg, Maryland
site. For those buildings which are judged to have
deficiencies according to the checklist in FEMA 178,
additional analyses were carried out to determine
whether in-situ structures are adequate for "life
safety." If passed for life safety evaluation, the
structure is judged to have no deficiencies.
Rehabilitation costs for the non-evaluated buildings
were derived from the rehabilitation costs of the
evaluated buildings. The location of building is
considered in the estimation of the rehabilitation cost.
The cost estimates are also adjusted to 1998. The
rehabilitation costs include structural, non-structural,
finishing and administration costs. The total estimated
rehabilitation cost for the FEMA buildings is $13 910
