My Build Log

 Platform section made using the 2x2 grid system for game asset creation, I've done this because i wanted to be able to more easily tile my geometry to create the wall of the room

 HVAC pipes, water system and Gas mains(on Pandora cleaning the Air and Water would be very important) I have made a feature of these pipes to emphasis their importance in the structure.

 Upper Walkway
Walkway has LED strip lighting as this is a low light area to save on power usage in the water treatment plant. Also I have decided on the function for the room it will be a area for large water cleaning machines that keep the base of Hellgate in freash drinkable water on the human hostile planet of Pandora.
