When Prometheus calls the first time, he tells them to go to an abandoned hotel to view his work and doesn't mention any other buildings. However, the building where the bomb actually is located at is a clothing warehouse. The fire department searches there first and finds the bomb. The hotel is across the street and it is later revealed Prometheus is hiding there. If the fire department had gone to the hotel as Prometheus directed, they would have captured him and not found the bomb.
