Use calculations in work breakdown structure
Activity Flow

In a project quotation work breakdown structure, you can set prices on several levels. For example, project quotation, task, or estimate line.

The total sales value is calculated based on the quantity times the sales price.

If the project type is:

  • Time and material: sales prices have a direct consequence for the project invoicing.
  • Fixed price: sales prices are shown by the on-account transactions.

In construction projects, quantities are often calculated based on specific settings.

In Project Control Suite, this is done with calculation groups.

Calculation groups define:

  • The formulas that are used to calculate the estimate line quantities for activities in the work breakdown structure.
  • Models with the default formulas for each transaction type.
  • The setup that is required for progress billing: a variable that is marked as scheduled unit. For progress billing, usually, the scheduled unit variable is a percentage.
  • The setup that is required for subcontracting: a variable that is marked as scheduled unit and for which the unit is defined as well.
    Reason: subcontracting uses purchase orders. On the purchase lines, a unit is required.
  • A cost price (expense) or sales price (expense) for a specific scheduled unit.

Review bid value and markup

Review bid value and markup

You can review and modify the bid values and bid rates, as calculated by the WBS calculation. You can, for example, compare the bid value with the calculated markup.

You can change the bid value in these ways:

  • Add a contingency.
  • Apply an index.
  • Manually change the bid rate or bid value.
