Costing in Design

• Steel, sections and plate£169.15

  71.98 kg, works out at £2.35 per kg

  Posts, rails, bars and plate. The steel rate is your mild steel rate per kg, and every other material multiplies it by its own factor, so mild steel sits at 1.

• Fixings and hardware£46.40

  Clamps, spigots, standoffs, channel, bends, end caps, brackets, anchors and any cored pockets.

• Workshop fabrication£143.64

  3.42 hours, works out at £42.00 per hour

  Cut, drill, weld and dress, estimated from the part count.

• Galvanising£34.55

  0.072 t, works out at £479.99 per t

  Charged by weight, which is how a galvaniser charges.

• Delivery£85.80

  3.2 m, works out at £26.81 per m

• Drawings and setting out£40.00

  Setting out and the fabrication drawing. A raked run adds the panel geometry drawing on top, so a stair costs more on this line than a level run.

Excludes VAT. Nothing to charge for Glass, Mesh and panel infill, Wire and tensioners, Coating and polishing, Installation, Margin on this configuration.
