The Charles Gates Dawes House is a historic house museum built in 1894 and was the home of Charles Gates Dawes, former U.S. Vice President and Nobel Prize winner. The building is a National Historic Landmark. The Dawes House is currently home to the Evanston History Center. TSG has collaborated on several projects for the restoration and repair of this building. TSG was hired to address repairs and reinforcement to portions of the existing mansion, its coach house and its adjacent terrace. Work included reconstructing the main house entry stairs at the front (south) facade including the adjacent stair walls. TSG evaluated the first floor framing above recently installed mechanical equipment in the basement and the stability of the existing roof framing, while paying particular attention to the affect of roof rafter thrust on third floor walls cantilevered from the third floor and supporting roof rafters above the third floor level. TSG also evaluated the attic floor framing of the southeast turret to determine whether the floor structure required reinforcement and replaced the north and south exterior stairs at the east terrace. Portions of the first floor joist framing in the coach house were sistered, and the existing girders were evaluated.
