The project is a study that investigates current conditions and the expected condition after the remediation project by the Navy of Hangar One, as well as cost estimates for potential rehabilitation options.

Conclusion
While we do not dispute that historic preservation is a worthy consideration, we question whether
expending more than $32 million to re-side a hangar that has no prospects for reuse for the
foreseeable future and would require substantial additional investment to make it habitable is the
best use of NASA’s limited construction resources. Moreover, dedicating funds to Hangar One means
that other critical renovation and repair projects will be delayed, which could result in unsafe working
conditions, higher annual maintenance costs, and damage to Agency equipment. Given these risks,
we believe NASA should analyze the full range of options before taking further action regarding
Hangar One.
Options Required for the CARP Regarding Hangar One
• Re-side Hangar One as described in the Budget Request and determine the annual maintenance cost assuming no
intended use;
• Re-side Hangar One and make the necessary upgrades and repairs to enable use as a hangar;
• Re-side Hangar One and make the necessary upgrades and repairs to enable public assemblies;
• Demolish Hangar One and carry out historic preservation mitigation actions; and
• Transfer Hangar One to another government entity under the Historic Surplus Property Program.

Condition Assessment and Rehabilitation Plan for Hangar One
STATUS
November 3, 2011
Objectives:
The project is a study that investigates current conditions and the expected condition after the
remediation project by the Navy of Hangar One, as well as cost estimates for potential rehabilitation
options.
The study will include:
• All Options as required by the OIG, however, the CARP does not include the assessment of transfer
options.

3. CARP
Condition Assessment and Rehabilitation Plan for Hangar One
Options
Option A. Basic Re-Skinning, Maintain Existing Occupancy as a Hangar
• Re-skinning for future use and for preservation of the historic building.
• Structural modifications only where necessary due to hazardous conditions.
• Provide basic services such as lighting, power and toilet rooms to continue use as a hangar.
Option B. Re-Skinning with structural and other upgrades for re-use as a Hangar
• Provides all items noted in Option A.
• In addition, analyze geotechnical improvements and structural upgrades per Life Safety performance levels.
Option C. Re-Skinning with structural and other upgrades for re-use as a Hangar
• Provides all items noted in Option B.
• In addition, calls for rehabilitation with historic considerations required by California Historic Building Code.
Option D. Adaptive Re-Use, Re-Skinning with Upgrades (Geotechnical, Structural) and Re-Use as a
higher Occupancy Level (from Hangar to Assembly, or Mixed Use)
• Provides all items noted in Option C
• In addition, complies with all California codes for life safety aspects for higher occupancy use, such as sporting fields,
training space, temporary movie sets, office space, museum, conventions and retail space, etc.

4. CARP
Condition Assessment and Rehabilitation Plan for Hangar One
Options
Option E1. Layaway Plan (maintenance without occupants) after re-skinning
• Includes annual cost and maintenance requirements associated with the re-skinned hangar per Option A.
- Electrical power for basic lighting and hangar door operation, annual roof inspection, etc.
Option E2. Layaway Plan (maintenance without occupants) while structure is exposed
• Includes annual cost and maintenance requirements associated with the un-skinned hangar based on the exposed,
steel structure remaining in place.
- Ground maintenance for vegetation and weed control, potential ongoing remediation of
sediment ponds, etc.
Option F. Demolition Costs
• Following remediation efforts currently in progress by the Navy, the remaining portion of the facility requiring
demolition includes the existing steel frame, concrete foundation, concrete slab, hangar doors and components
(motors, trucks, pivots), miscellaneous site utilities plus the contaminate materials.

STATUS
CARP Schedule
Early July 2011 - Kick-off Meeting
Mid October - Draft for Review
November - Completion
CARP Current Status:
The 95% draft submittal have been received and the contractors are working to the required objectives. The CARP is
progressing per the IG audit to be completed by the end of November and once it is approved by NASA, it will be
made available to the public.
