Ceilings in Building 29A are fissured mineral fiber acoustic tiles. Many of the walls, including those in corridors are plastic laminated wall panels. Inside some laboratories there are also beige glazed structural facing tile-clad walls. In the basement corridors, animal rooms and cage washing room, the walls are simply painted concrete block. The first floor library/conference room features quarter-sawn walnut paneling and trim.

Doorways and doors

...

The corridors are enclosed by double-leaf, metal fire doors. Individual laboratories and offices feature single-leaf, half-glazed, metal doors. Stairwells have single-leaf, metal doors. In construction drawing specifications there were also plastic laminate doors described as a solid wood core with plastic covering, but it is not clear where these doors were located.

Windows

...

There are no windows in any of the laboratories or offices since they all face the interior and are located within the interior of the surrounding perimeter corridor.The windows along the corridor are of dark, anodized aluminum-framed, with gray-tinted glass.

Mechanical equipment

Heating, air conditioning, ventilation

...

Engineering/architectural controls were put in place to the keep the working environment of Building 29A functional and safe. Building 29A had both animal rooms and many infectious diseases being tested within its walls. For example, air intake towers, located in the median of the parking area to the north of the building, provided clean incoming air for the mechanical system in the basement, while a high velocity exhaust air system was placed on the roof/penthouse to ensure dilution and dispersion of laboratory and vivarium exhaust air. The basement has almost 22’ tall ceilings to accommodate the mechanical equipment and a refrigeration repository.

Lighting

...

Due to the layout of Building 29A, there is no natural light in any of the laboratories. The basement is also quite dark without the lights turned on. All spaces were supplied with overhead lighting originally, but it is likely that many of these fixtures have been replaced over time, as most of what remains in the building today are suspended fluorescent lights.

Plumbing

...

When originally built, plumbing was routed to the laboratories through the utility cores. Over time, this system became outdated and interstitial spaces were used for utilities instead. Bathrooms were located on the first through third floors near the elevators and Stairway #1 on the north side of the building. Each laboratory would also require its own plumbing, in addition to the cage washing room in the basement.

Original furnishings

Some original fixtures and furnishings remain in Building 29A including intact cold rooms, drying racks, metal cabinets, shelves, water fountains, sinks, including at least one original soapstone sink, eyewash stations,showers, aluminum room signs/placards and bulletin board, a liquid nitrogen tank, and mail chutes. There is also cage washing equipment in the basement of Building 29A, but it is not clear if it is original.
