1.9.6 Suspension of River Traffic and Construction

1.9.6.1 Withdrawal of Equipment and Floating Plant

All floating plant shall be withdrawn from a gate bay when the projected total operational gate opening is forecasted to reach 35 feet or greater.

Once the total operational gate opening reaches 35 feet, floating plant may temporarily moor to the outside of the Lower Guard Wall directly below the spillway as long as the total gate opening is not projected to reach above 39 feet. This must be closely coordinated with the Lockmaster. If the total operational gate opening is forecasted to reach 40 feet or greater, the equipment shall be relocated to the outside face of the upstream river wall or to the Contractor's off-site mooring location. The decision of whether the Contractor's plant may be moored to the upstream River Wall will be determined on the basis of the projected upstream pool level. When the upstream pool level reaches an elevation of 686.0 feet (U/S Gage = 16 FT), the Contractor shall begin preparations to move the floating plant. If the upstream pool level is expected to reach an El. of

690.0 feet (U/S Gage = 20 FT) then mooring of the plant at the off-site location will be required. The Contractor shall monitor the prevailing river conditions at the project site, referring to the upstream project river gage, river forecasts issued by the National Weather Service, and the Corps of Engineers River Forecast System, and shall determine when to

SECTION 01 35 00.00 08 Page 12 withdraw equipment and floating plant. Projected dam gate operations shall be coordinated with the Lockmaster and Contracting Officer or their designated representative. The withdrawal of equipment and floating plant shall ultimately be the Contractor's decision and will not be directed by the Government. It shall be the Contractor's responsibility to determine the time necessary to make a complete and safe withdrawal of equipment and floating plant with due consideration given to the location of mooring area; amount of equipment; size of the floating plant, and capacity of towboats and propelling units to operate safely and efficiently at the expected river velocities. All floating plant and equipment shall remain securely moored during the period that gate openings exceeds 40 feet or when the pool is at or above the specified level. The Contractor shall also be responsible for providing personnel during the suspension to adjust mooring lines as required by the prevailing river conditions.

1.9.6.2 Plan of Action, Withdrawal of Equipment and Floating Plant

1.10.2 Requests for Lockage Through Main or River Chamber

The Government recognizes that the Contractor may need to lock through the the River Chamber, however, these lockages must be fully coordinated with the Lockmaster and kept to an absolute minimum to ensure there are no delays to commercial river traffic. All lockages must be subject to the following:

a. The Government retains the right to determine the order and priority of lockages at the sole discretion of the Lockmaster. The Government reserves the right to supercede and delay any requested lockage for any reason (such as increased commercial river traffic, maintenance, equipment failure, emergencies etc.) at the sole discretion of the Government. The Contractor is advised that these delays will not be subject to Section 00 70 00 CONDITIONS OF THE CONTRACT, FAR 52.233-1 DISPUTES, and shall not be considered as direction from the Contracting Officer or designated representative.

These delays will not result in any additional time extensions or payment of any delay costs, nor shall they be the basis of any claim against the Government.

b. The Contractor is not permitted to use the Main or River Chamber for staging of equipment.

c. All requests for lockages must be coordinated with the Lockmaster in accordance with the following provisions:

1) Upon approval of an estimated date and estimated time for a proposed lockage, the Contractor must be ready to perform the requested lockage. The Contractor is advised that the Government

SECTION 01 35 00.00 08 Page 14 will not be liable in the event the Chamber is not available at the requested date and time, and that any resulting delay will not be subject to Section 00 70 00 CONDITIONS OF THE CONTRACT, FAR 52.233-1 DISPUTES, and will not result in any additional time extensions or payment of any delay costs, nor shall they be the basis of any claim against the Government.

2) The Contractor must configure his floating plant, work operations and all equipment to allow safe, uninterrupted lockage through the Chamber in such a manner that no delays to the normal lockage time period will be incurred.

3) The Contractor is advised that the request for lockage may be delayed or postponed indefinitely due to unexpected conditions such as high water, lock breakdowns, or unanticipated maintenance demands, etc.

4) Requests for lockages that do not meet these criteria will not be approved. Requests for unscheduled lockages due to anticipated flooding or other emergency will considered on a case by case basis. Lockages or other interference with river traffic due to any situation which endangers human life will be permitted as the circumstances warrant.
