(Carry forward to Page 3-9)

TOTAL ALLOWANCE FOR SCHEDULE OF PRICES TO COVER ALTERATIONS, EXTRAS OR DEDUCTIONS (EXCLUDING HST) The contingency and cash allowances listed in this Schedule are for potential Work which may be required beyond the scope of this Contract. The unit prices entered by the Bidder for the items listed in this Schedule shall be used by the City to determine payments for the Work where those Work items are ordered by the Consultant, and shall also be used by the City to determine credits to the City from the Contractor where quantities ultimately required for unit price items under the base scope of the Contract are less than the original Contract quantities. The unit prices in the schedule shall not include HST nor overhead and profit. The unit prices inserted above for provisional quantities shall be used to determine payment for those items or credits even if actual quantities are found to vary considerably from them. In accordance with CCDC-2 Part 4, the Contract Price includes the cash allowances and the Contract Price includes all overhead and profit for those allowances. Profit and overhead on cash allowance Work will be in addition to the figures in the Schedule and will be calculated in accordance with the Contract Documents. In accordance with CCDC-2 Part 4, the Contract Price includes the contingency allowance listed in this Schedule. The contingency allowance includes all overhead and profit in connection with Work undertaken under the contingency allowance. The Bidder agrees that no part of the cash allowances or contingency allowance shall be expended without written direction from the Consultant. Payments from the contingency allowance will be made only following issuance of a Change Order approved by the Consultant. Any unused portion of the contingency allowance and cash allowances, and any credits to the City for unit price items shall be deducted from the Contract Price. In the event of obvious mathematical errors in the Schedule of Prices, the unit prices tendered shall be considered correct and arithmetic extensions and totals shall be corrected accordingly. Any such corrections resulting in adjustment to the total for the Schedule of Prices will be similarly applied as an adjustment to the Total Lump Sum Price tendered for the project.
