Stabilization
• For this cost analysis ‘stabilization’ includes the following
costs:
– The above costs that would be associated with the
abatement and removal and disposal of hazardous
materials.
– This analysis includes the method of stabilization as
recommended by the NPS in their report and when options
were provided the simplest method was chosen. Simply
put buildings were stabilized by being weather-proofed
simple roofs were applied when necessary and windows
and doors were sealed to prevent access by trespassers
and weather. The most cost effective solutions were
sought.

From AAHP
• Recommend if costs of stabilization exceed cost of demo
that building is left ‘as is’ until funds become available.
• Recommend minimal protection/stabilization which
would include sealing the building in plywood and
weatherproofing the roof until such time as private or
other funds become available.
• If demo is the only option consideration should be given
among future partnering opportunities and possibilities to
allow for a future interpretive option which could include
a concept such as outlining of the building mass in
tubular weathering steel.

FONSS
• Pleased and concurs with NPS EXCEPT:
– They don’t feel the Launch control building could be stabilized
inexpensively and feels the cost analysis needs to address the
three different components of the building.
– A full EPA and OSHA compliance analysis should be conducted
and the cost analysis should be updated as necessary prior to
any demolition.
– They encourage USAG AK to pursue securing the concrete wing
and re-roofing as soon as possible.
– Recommend cost comparisons prior to any action being
undertaken.
– These reports are all based on visual assessments a hazardous
materials survey must be completed prior to demo or stabilization
and update costs as necessary.

impact demo would
cause.
