Conclusion

While we do not dispute that historic preservation is a worthy consideration, we question whetherexpending 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 thebest use of NASA’s limited construction resources. Moreover, dedicating funds to Hangar One meansthat 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 nointended 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.

CARPCondition Assessment and Rehabilitation Plan for Hangar One

STATUSNovember 3, 2011

Objectives:The project is a study that investigates current conditions and the expected condition after theremediation project by the Navy of Hangar One, as well as cost estimates for potential rehabilitationoptions.

The study will include:

• All Options as required by the OIG, however, the CARP does not include the assessment of transferoptions.

CARPCondition Assessment and Rehabilitation Plan for Hangar One

OptionsOption 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 ahigher 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.

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 ofsediment ponds, etc.

Option F. Demolition Costs

• Following remediation efforts currently in progress by the Navy, the remaining portion of the facility requiringdemolition includes the existing steel frame, concrete foundation, concrete slab, hangar doors and components(motors, trucks, pivots), miscellaneous site utilities plus the contaminate materials.
