PART 1 – GENERAL

ITEM 1 - DESCRIPTION OF WORK

1.1 Background: The Frank and George Wallace Homes at HSTR are vital components of the maintained cultural landscape of the Truman Home family compound, and are integral to the

Harry S Truman Historic District National Historic Landmark. The homes belonged to Frank and

Natalie Wallace, and George and May Wallace, brothers and sisters-in-law of First Lady Bess

Wallace Truman. Homes date to 1915/ 1916 and was the Wallaces’ home until their deaths in

1960 and 1991 respectively. Although not open to the public, the exterior of the homes are used as a visual exhibit to provide visitors context as to the historic character of the Truman Home compound and the closeness of the family. This project will repair and replace the asphalt shingle roof and the wood rot on the soffit and facia of both homes. Contractors or the NPS

Maintenance Action Team will perform the replacement of the roof and the new wood will be primed and painted before it is installed. This project has important components of the structure that will greatly aid in the ongoing maintenance of the structures.
