Answer

When creating a new variation from a change event or linking a change event line item to an existing variation, the bill of quantities (BOQ) in the variation will populate with a value from the change event line item source. This article summarises how the value is determined within the change event line item so you will know which values will carry over into the variation. 

Commitment Variation

When creating or linking a commitment variation or potential variation, the Latest Cost amount for each selected change event line item will carry over into the variation BOQ.

 Note

If a potential variation or main contract variation is linked to the change event before linking a commitment variation, the Latest Price amount will override the latest cost and pull through to the commitment variation BOQ. 

If this happens, you can edit the value for the BOQ line item on the variation after it is created/linked.

Main Contract Variation

When creating or linking a main potential variation or main contract variation, the Latest Price amount for each selected change event line item will carry over into the variation BOQ.

How are the Latest Price and Latest Cost Values Determined?

Latest Price

The latest price is determined by the most up-to-date value in the revenue portion of the change event line item columns. This includes the ROM and Main/Prime PV columns. The Revenue ROM value is used to determine the initial latest price value. Once a 'Main/Prime PV' value has been added, the latest price will update to match the 'Main/Prime PV' column.

Are you using the Revenue ROM function?

If your project team has opted to use the Revenue ROM function, the BOQ on your main contract variations is also automatically updated. If you have hidden the Revenue ROM function, any automatic updates depend upon the scope of the change event:

  • When change events are 'In Scope' or 'TBD', the BOQ on the main contract variation is automatically updated with a £0 value.
  • When change events are 'Out of Scope', the BOQ on the main contract variation is automatically updated using the data from the RFQ when the RFQ status is set to 'Pending Final Approval.'
  • When change events are not in one of the above statuses, the BOQ is automatically updated using the Cost ROM.
Latest Cost

The latest cost is determined by the most up-to-date value in the cost portion of the change event line item columns. This includes the ROM, RFQ, and Commitment columns. The cost ROM determines the initial value of the latest cost. After that, an RFQ value and finally a commitment value is used to set the latest cost on a change event line item.
