The Work to be done under the Contract shall consist of the construction of clay dikes along the Primary and Secondary Dikes within the City of Winnipeg and loading of clay borrow material from the borrow site. Depending on site specific river levels, clay dike locations and sizes will be determined by the Contract Administrator as required. The Contract Administrator reserves the right to add or remove clay dike locations. The most current flood forecast is projecting an upper decile elevation of 20.1 feet James. This elevation has an approximately 10% chance of occurring. Approximate quantities of clay dike under this scenario are shown on Form B. As the flood forecast becomes more defined, actual quantities will increase or decrease, or be cancelled as a result. The following shows clay dike quantities:
(a) Scenario 20.1 feet James
(i) Turnbull Drive - 1900m3
