Excavation of the NOvA Near-Detector Cavern is complete. Since this photo was taken, workers have installed a new concrete floor over the exposed bedrock to be level with that of the existing facility. In the final phase of the project, workers will install the infrastructure necessary to support the future near detector, including steel platforms and ceiling, electrical and mechanical utilities, fire doors and walls and other safety devices.
