The second floor restrooms at Building 311 underwent a complete renovation. The existing tile contained lead and the gypsum board and taping mud contained asbestos. The demolition of the two restrooms was performed under containment. Gypsum board was installed on the walls and ceilings, and painted. Porcelain floor tile and wainscot with accent rows were mortared in place and epoxy grouted. Plastic laminate countertops with top mounted lavatories, under-mounted cabinets and mirrors were installed. The work included new toilet partitions and accessories. New plumbing fixtures and lighting were installed.
Due to high building security, all work was performed under Lab escort which required advanced scheduling of material deliveries and labor.
