# Material Rates / Prices  This is the cost of purchasing the materials required. It is not a simple matter of getting a price (over the phone, for example) and using it, because supply process are often not that simple, or consistent.

Some examples:

Plasterboard supply prices may be provided as \$-per-sheet. You would then need to know the sheet size and how to convert this into a cost per square metre, as this tends to be the way it is measured;

• Supply Price @ \$34.oo per sheet
• Sheet size, 3600 x 1200mm
• Price per square metre (m2) is \$34.00 / (3.6 x 1.2)  = \$ 7.87/m2

Timber supply prices may sometimes be provided as \$-per-cubic-metre (\$/m3), though we tend to think, and measure, in metre lengths … And so you will need to know how to convert the price from \$/m3 to \$/m;

• Supply Price @ \$2,500.00 per cubic metre (m3)
• Timber beam size, 195 x 45mm
• Price per metre (m) is \$2,500.00 x 0.195 x 0.045 = \$21.94/m.

Brick supply prices may be \$-per-1000, though we tend to think in \$/m2 … And so you will need to know how to convert the prices from \$/thou. to \$/m2;

• Supply Price @ \$1,200.00 per thousand
• Brick size is 230 x 76 x 110mm thick
• Effective size is 240 x 86 x 110mm, for calculating quantities
• Number of bricks per square metre is 1 / (0.24 x .086) = 48.45
• Price per square metre (m2) is \$1,200.00 / (1000 x 0.24 x 0.086) = \$58.14/m2 or,
• Price per square metre (m2) is \$1,200.00 / 1,000 (ie \$1.20 each) x 48.45 = \$58.14/m2

And though consideration must be given to supply rates/prices, you will need also to consider the following:

• Waste
• Minimal ordering quantities
• Transport and deliveries
• Storage
• Faulty materials and replacements
• Insurances, guarantees and warranties
• Samples
• Prototypes

Note: You will also need to be very clear about whether your prices include, or exclude, GST.
