Common use of Variation to Scope of Works due to Scope Change Event Clause in Contracts

Variation to Scope of Works due to Scope Change Event. If the Project Manager considers, acting reasonably, that it is necessary to vary the Scope of Works for a Segment as a result of a Scope Change Event, then the Project Manager: (a) may, by notice to the Trustee, the Independent Engineer and the PUH Engineer (also a Variation Notice), request the consent of the Trustee to vary the Scope of Works for the Segment as a result of the Scope Change Event as proposed in the Variation Notice; and (b) must, if the Project Manager gives a Variation Notice under (i) the Scope Change Event and the effect of the Scope Change Event on the Scope of Works for the Segment; and (ii) why the Project Manager considers the proposed variation of the Scope of Works for the Segment is the preferred manner of addressing the Scope Change Event.
