Last week in the underground NOvA near-detector hall, Kiewit construction workers removed conduits from the east wall where the NOvA cavern will be located. The variety of conduits move water, electricity and signals for the fire and accelerator systems, among other utilities.
A three-day outage allowed the workers to disconnect the old systems and connect the new systems, which workers have been installing on the west wall over the past few months.
