The National Society of Colonial Dames wished to restore the home to its original condition, remove a first floor partition and to repair a large restroom area on the second floor, which was supported by deteriorating timber columns. A&O designed the replacement supports for the restroom and conducted non-destructive investigation to develop schematic repair recommendations for the first floor.

A&O analyzed the structural load capacity of the framing system for the restroom and provided construction drawings for demolition and the new support system. For the first floor repairs, A&O measured and documented the structural framing from the roof attic, second floor, first floor, and crawl space, visible cracks, settlement, noted previous repairs, and areas that would require additional investigation. A&O assisted in providing a written report, evaluating the information, and prepared a schematic approach to the removal of the lower partition wall and repairs needed to strengthen the second floor, partition, ceiling joists, beams, and king post truss.
