Aircraft; Airport; Human Factors
On the last leg of a rerouted four-day trip; we were right base visual in VMC conditions. We have both done the same visual approach a million times. Captain was pilot flying and called for the Landing Checklist as we turned final. This brought his eyes inside for a few seconds. When he brought them outside; he realized he was slightly high. He made appropriate efforts to correct his aircraft state and slightly increased his sink rate. We received a 'Caution Obstacle' (if memory serves correctly) and the Captain immediately went around. We entered a right downwind; for another visual approach with a successful outcome. Good job for the Captain having the discipline to go around. We let complacency get the best of us. We both realize that regardless of familiarity; we need to stay focused and alert as a functioning team.
Cleared for a visual approach; configured with gear down flaps 30 from right hand base rolling out on final; got Caution Obstacle warning. Executed go-around and got vectors back to another visual approach and landed. I think it was a minor sink rate deviation close to buildings that caused the Caution Obstacle warning.
