The purpose of this project was to perform all necessary removal and repair to the Interior Ceiling of Bldg. 55 at the Ft. Meade Campus, SD. Work consisted of removal and disposal of existing acoustical ceiling tiles (2,400 sq ft). Removal was done carefully in order to minimize damage to the underlying plaster. Any damaged tiles were also repaired or replaced. 7/16” Oriented Strand Board (OSB) over existing plaster was installed ensuring sufficient anchoring to roof trusses with appropriate screwed fasteners. ½” Gypsum Board was installed over OSB, seal joints, primer one-coat, and painted two-coats. Additionally, mud-rings and/or box extensions as needed were installed and all existing light fixtures, vents and other accessories were re-attached. ¾” wood concave quarter round molding and decorative corner trim was installed and painted/finished.
