The storyboards set in place, the next important piece was to look locally at potential locations to film. The first place found was in a warehouse:

This was a potential place for the hallway shot.

After finding this location, the storyboards were reflected upon, and a transition from the outside shot with the door, to the inside corridor had to be revisited and revised.

The building had been changed to a bunker, so stairs were found so there would be transitional shots between the outside and inside of the corridor.

This shot will be composited into the back of the corridor, to join the two.

The stairwell will be highly in use during shoot, and close to the in-use stairwell was a derelict set, which was di-used. This seemed ideal to use for the main stairwell shots, where 3D walls could be composited.

 

On the way back, an establishing shot was taken on a bridge, where the Citadel would be composited into:

The warehouse where the corridor scene is to take place was looked at again as a potential location for the outdoor shot where the character moves towards the door:

This was the better place to film the first shot, the only problem would be getting the dolly track set up, and asking whos car was in the way to move them until the shooting was finished.
