GC 7 MEASUREMENT AND PAYMENT
GC 7.01 QUANTITIES-
The quantities set out in the Schedule of Unit Prices are the estimated quantities of the Works, and they are not to be taken as the actual and correct quantities of the Works to be executed by the Contractor in fulfillment of his obligations under the Contract.
-
The Engineer shall, except as otherwise stated or agreed, determine by measurement the value of the Work done all in accordance with the Contract. He shall, when he requires any part or parts of the Works to be measured, give notice to the Contractor who shall forthwith attend, or send a qualified agent, to assist the Engineer in making such measurements; and shall furnish all particulars. Should the Contractor not attend, or neglect or omit to send such agent, then the measurement made by the Engineer, or approved by him, shall be taken to be the correct measurement of the work.
GC 7.02 WEIGHING GRANULAR MATERIALS
The scale location shall be as approved by the Engineer and the material shall be hauled directly from the scale to the point of application. The scale may be located at the source. Except that where there is a waste or loss of material, the hauling operation shall terminate until the Contractor shall provide, at his expense, scales licensed in accordance with the Weights and Measurements Act.
GC 7.03 VALUATION OF VARIATIONS
i. The Engineer shall determine the amount (if any), to be added to, or deducted from, the sum named in the Tender in respect of any extra or additional work done, or work omitted by his order. All such work shall be valued at the rates set out in the Contract, if in the opinion of the Engineer, the same shall be applicable. If the Contract shall not contain any rates applicable to the extra or additional work, then reasonable prices shall be fixed by the Engineer.
a. Provided that if the nature or amount of any omission, or addition relative to the nature or amount of the whole of the contract work or to any part thereof, shall be such, that in the opinion of the Engineer, the rate or price contained in the Contract for any item of the Works is, by reason of such omission of addition, rendered unreasonable, or inapplicable, the Engineer shall fix such other rate or price as under the circumstances, he shall think reasonable and proper.
