Fairfax County Old Jail

Condition Assessments 

Fairfax, VA

Fairfax County Old Jail | Condition Assessments | Fairfax, VA

At the request of Fairfax County Facilities Maintenance Department, Setty has conducted a limited structural investigation, review and assessment of the condition of the Fairfax County “Old Jail” building, a historic building of approximately 5,800 square feet presently occupied by the Sheriff’s office.

Assessment of the Old Jail building found the building structurally sound without any apparent damage.  The building is safe for continuing occupancy with normal maintenance of the exterior envelope and supporting building systems.  The investigation revealed some existing defects which are recommended for specific repair and cannot be addressed by maintenance alone.  Damage to exterior brick corbelling exacerbated by movement due to the August 23, 2011 earthquake and moisture damage at the roof’s original wood ridge beam were two of the critical findings of this assessment.  These deficiencies are identified, prioritized and have been estimated based on suggested conceptual design fixes illustrated in the report drawings.
