• The preliminaries, extras and Main Contractors Discount are spread across all the material and labour to form a unit rate for every part and create a Schedule of Rates.
  • For each of the costs you can choose whether to spread them over material, labour or both.
  • The preliminaries and extras are added to the tender price without any additional overhead or profit markup, as it is assumed that the cost of preliminaries and extras is passed on directly to the client. If you wish you can include any overhead or profit within the costs stated here. For example, if cost of scaffolding hire is £1,000 you may want to enter £1,100 to include 10% for handling.
  • If you do not wish to spread preliminaries and extras on materials and labour then you should create separate Items for them and add each entry as a special or from your local data, leaving the values here blank. You would then be able to add overhead and profit, and the preliminaries and extras would be shown priced separately on the quotation.

Main Contractors Discount

What is the Main Contractors Discount?

  • The Main Contractors Discount (MCD) is usually 1/39th or 2.5% discount on the tender amount for payment within terms, however the amount can vary.
  • Although referred to as a ‘discount’ the MCD is added to the subcontractor’s tender amount that the main contractor submits to the client. When the subcontractor invoices the main contractor he deducts the MCD for payment within terms, hence the term ‘discount’.
  • To add the MCD you have to calculate what the tender price would be so that when you take off the MCD you get back to your original value.
  • This is done using the formula:
  • Tender price after MCD = tender Price before MCD / ( (100-MCD%)/100 ) e.g. tender Price before MCD was £10,000 and MCD of 2.5% Tender price after MCD
  • = £10,000 / ( (100-2.5)/100) ) = £10,000/0.975 = £10,256.41
  • When giving the discount you then take 2.5% off the £10,256.41:
  • 2.5% discount = 0.025*£10,256.41=£256.41
