These were taken in the office. From the lift generator onwards, the pictures are taken when I was given a rare access to the roof top of my office tower.

I am quite surprised that the lift generators are really not very big, and they can actually haul quite a big number of people. (For security reasons I did not take photos of the other equipment in that room.)

You might also want to take note of the lightning rod in the foreground of the picture taken in the direction of Republic Plaza and some of the equipment on the roof of the other buildings.
