the measurement of existing features or ground levels and the like, then prior to carrying out any

operations which might affect such measurement, the Contractor shall first take such levels and

measurements as the Engineer may direct and, after the Engineer has had the opportunity to

check the same, they shall be certified as agreed by both the Engineer and the Contractor. In the

event that the Contractor fails to observe the above procedure, the Engineer shall determine the

quantity to be assumed for payment purposes using the best information available to him, and his

decision in the matter shall be final.

Items in the Bill of Quantities where “Rate Only” is specified shall be priced as required for a unit

quantity of that item and shall not be carried to the total of Bill of Quantities.
