WBS calculation updates the bid rate and bid value for each task.

The relevant calculations are:

• Bid value = Calculated value + Contingency + Index
• Calculated value = sum of Total sales prices of all estimate lines for the task
• Bid rate = Bid value / Forecast quantity in Scheduled unit
• Calculated rate = Calculated value / Forecast quantity in Scheduled unit

You can manually change the bid rate and bid value. If you do so, these are automatically locked.

If the bid rate and bid value are locked and you run the WBS calculation:

• The bid rate and bid value aren't changed if:
  • Prices are changed.
  • You add a contingency.
  • You apply an index.
• The bid value is changed if quantities are changed on a task. In this case, the locked bid ratio is used to calculate the new bid value.

You can unlock the bid rate. To do so, on the Advanced WBS page, on the calculation fast tab, clear the Lock bid rate check box.
