Narrative:

We were setting up for a right base for runway 36L into hsv with the captain being the pilot flying. It was just after dark; we had called the field in sight and began our descent to traffic pattern altitude; after being cleared for the visual approach. On the right base as we were descending the captain asked me if I thought we were too low and I went to look at one of the approach charts into hsv. When I looked at the chart in relation to where we were I said that I thought we were fine. As soon as I said this we simultaneously were told by ATC that they were getting a low altitude alert for our flight and a GPWS warning to pull up. The captain disengaged the autopilot and began to climb and I notified ATC that we were correcting our altitude. After correcting our altitude to a safe altitude we continued the approach to a safe landing.the event occurred because runway 35R was out of service and the ILS was out of service to runway 35L. We decided to set up for a visual and thought we were closer to the airport in relation to terrain than we thought. Therefore we descended to traffic pattern altitude too early.
