Hey guys i need some help with drawing an electrical schematic for this office floor, im not sure what i am doing is right, does maximum demand have to be in amps? also how do i work out the demand for the plant room lighting? and how do i do the floor plan schematic?

the first part is fair easy being all basic max demand stuff but then designing it all and drawing it onto the plan is getting hard ive never seen that before but from my knowledge just draw your cable runs and mark them as necesary (main board, sub board etc)

other then that i have no idea at all is this for engineering i never got into that much in the nsw trades course

You'll need to consult the Australian standards for the maximum demand calculations. There are 2 or 3 modules at trade school dedicated to this one topic alone.....

As for the lumens, that will depend on the fittings chosen, the diffusers used, design of the light, the actual globes/leds/etc used, etc etc.

You'll need to get the specifications from the manufacturer and work from there.
Most 3D Architectural visualisation software will allow you to input manufacturers lighting data into your 3D scene to accurately determine light levels and coverage. I use 3D Studio Max, but it's price tag is probably a little above your project.

Simply put, you've got a lot of number crunching ahead. :) I would get your hands on the relevant Australian standards and get ready for some dry bedtime reading.......
