Steel – F72 sheet steel covers 14 m² and costs about $100 per sheet
7mm steel bars x 200mm squares

Steel Beams
PFC is a U shaped beam
UB is an I shaped beam
UB 25 means 25 x the length of the beam gives you the weight in KGs
For example a UB25 x 5 m long = 125 KGs in weight (equivalent to 1 Kenny Campbell)

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
The higher the MPA number the stronger and more waterproof the concrete and also more expensive it is and will go off a lot quicker
20 MPA-40 MPA
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
Jam 5.4mm long in length costs $75
