7mm steel bars x 200mm squares
Stairs
Tread size is 240mm–300mm
Riser size is 170-190
Total rise divide by 180mm = number of risers
Total going divide by one less number of risers gives the tread size
Toilets
P trap out through the wall
S trap out through the floor
Floor Wastes
Make sure you plug the floor waste with a rag or bag before tiler starts to lay bed. Don't forget to remove once tiler has finished tiling.
Concrete

Use 25 MPA concrete for paths, footings, garage slabs etc
Costs about $ 220 m³
Doors (820mm wide x 2040mm long)
Hollow core door costs $30
Solid core door costs $95
