After the new contract price is determined, the liquidated damages or other payments calculated based on the contract price in the Contract Documents shall be adjusted based on the new contract price; If both parties have received (paid) liquidated damages or other payments based on the original contract price before the new contract price is determined, the relevant difference shall be uniformly adjusted in the completion settlement price. The new Priced Bill of Quantities through remeasurement will also be the basis for changing the valuation and related valuation and measurement (compared with the new Bill of Quantities, any item subtracted from the old Bill of Quantities can also be a basis).

If the Contractor fails to cooperate with the Project Owner to complete the remeasurement within the aforesaid period, the Project Owner shall have the right to suspend the construction cost until the remeasurement is completed and a supplementary agreement is signed. Any problem caused by the shortage of funds of the Contractor due to the suspension of payment under the aforementioned circumstances, such as the difficulty in purchasing equipment and materials, the difficulty in paying labour costs and the delay in construction, shall be borne by the

Chapter V General Technical Standards and Requirements .184.

Contractor. The Contractor shall not be entitled to any cost increase and (or) extension of time as a result.

(2) Valuation principle for remeasurement

The quantities after remeasurement shall be calculated in accordance with the measurement specification stipulated in the Contract Documents.

The valuation principle for the existing specific items with changed quantities in the remeasurement: The quantities shall be included in accordance with those shown in the construction drawings confirmed by both parties. The comprehensive unit price shall be that corresponding to the specific items in the Priced Bill of Quantities. The comprehensive unit price shall not be adjusted due to the increase or decrease of the quantities.

The valuation principle for specific items newly added in the remeasurement:

(1) If any similar item is in the Priced Bill of Quantities, the unit price of such similar item can be referred to within a reasonable scope;

Notwithstanding the preceding, for similar items in the Priced Bill of Quantities, the Project Owner shall also have the right to choose not to calculate in accordance with this Article, but to follow paragraph (2). The Contractor shall not raise any objection.

(2) If there is no applicable or similar unit price in the Priced Bill of Quantities, the price of changed work can be determined with the following methods:

1) Consumption: implemented in accordance with the consumption specified in the Valuation Basis for Construction Projects in Beijing - Budget Quota issued in 2012.

2) Labour, material, and machinery prices: If the corresponding labour, materials, and machinery prices have been listed in the priced bill of quantities, the existing implementation will be applied; if not, the lowest price limit in the Beijing Construction Cost Information in October 2019 shall be implemented; if there is no information in the Beijing Construction Cost Information in October 2019, it shall be implemented at a reasonable market price of the first month after the start of the remeasurement approved by the Project Owner.

3) The standards for collecting fees for the comprehensive unit price shall be subject to the standards determined in the Priced Bill of Quantities.

To avoid any doubt, the adjustment of specific items with fixed total price in the remeasurement shall follow the provision in paragraph 17.1.6 (3) of this Contract; For specific items with fixed unit price, only the quantities shall be adjusted in the remeasurement. The Contractor shall have no right to claim for the addition of specific items due to the missing items in the Bill of Quantities, inconsistent project characteristics or other reasons.

Chapter V General Technical Standards and Requirements .185.

After the remeasurement, if there is no change in the drawings, technical standards and requirements and other Contract Documents (hereinafter referred to as the "remeasurement basis") on which the remeasurement is based, and no omission is caused by the Contractor (if there is any, the Project Owner shall be entitled to deduct accordingly), the quantities in the remeasurement result shall be the ones both parties should follow when making progress payments and project settlement; if the remeasurement basis changes, and the contract price adjustment conditions agreed in the Contract Documents are met, both parties shall, when determining the settlement quantities, increase or decrease the account for the changed remeasurement based on the remeasurement result. After confirmation of the remeasurement result by both parties, the Contractor shall not have the right to advocate the adjustment of the remeasurement result or remeasure again on the grounds of quality deviation, missing items in the Bill of Quantities, inconsistent project characteristics or other reasons between the remeasurement result and the remeasurement basis.

To avoid any doubt, the changed valuation principle stipulated in Clause 15.4 shall apply only to the changes after the remeasurement, not to the missing items in the Bill of Quantities or the change before the remeasurement. Changes or missing items in the Bill of Quantities before the completion of the remeasurement shall be handled in accordance with the valuation principle for remeasurement agreed in this Article.
