Temporal Bone Lab Renovation at Lewis Hall, Eastern Virginia Medical Schools, Norfolk, Virginia
This project included the renovation of the Eastern Virginia Medical School’s, (EVMS), Temporal Bone Lab area on the second floor of Lewis Hall. Improvements included casework, custom workstations, doors, new wall, floor, and ceilings, new plumbing, HVAC, electrical and lighting systems.
The number of workstations within the 850 square foot area increased from eight movable workstations to sixteen fixed workstations with built-in plumbing, power and exhaust. The new design included local exhaust to address dust control issues with the existing space. The existing lab had no exhaust systems to remove the bone dust when users were drilling into their temporal bone samples. The solution formed by the team provided exhaust ventilation at each workstation via an adjustable exhaust snorkel. The dedicated exhaust system provides local exhaust at each workstation and filtration of the exhaust air mitigating bone dust particles within the space.
The mechanical design included all-new HVAC controls that interface with the Trane building control systems including full graphic integration. A dedicated exhaust system for the space with enhanced local workstation and room exhaust that includes filtration to remove the fine dust generated from the room procedures. The room is negatively pressurized to mitigate dust and odor migration to adjacent spaces. Air change rates and ventilation rates were designed in accordance with ASHRAE guidelines for similar spaces.
The plumbing design included piped domestic water to each workstation sink as well as a needle barb valve to provide tempered water for the user to apply to the bone sample, to mitigate dust, during drilling operations. Plaster traps were provided at each workstation to collect bone fragments that enter the sink drain prior to entering the building’s waste pipe system.
The electrical design included energy efficient dimmable LED light fixtures to light the space. Receptacles were provided above and below the work surface at each workstation to power drilling equipment, microscope, as well as the teaching camera system and monitor. The lab was provided with a standalone video system to broadcast video from the teaching station, or any other selected station, to each workstation during classes.
