Floating plant may be moored to the riverward face of the upstream river wall when the upper gage is below 16.0 as shown on Drawing C-1150 However, this plant must be completely removed and secured at an off site location that is no closer than one mile from the site, by the time the upper pool river gauge reaches 20.0.

Withdrawal or relocation of floating plant shall be completed within four hours of any notice from the Contracting Officer or their designated representative or Lockmaster.

1.11.6 Suspension of River Traffic and Construction

1.11.6.1 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All floating plant shall be withdrawn from a gate bay when the projected total operational gate opening is forecasted to reach 35 feet or greater.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 686.00 (U/S Gage = 16), the Contractor shall begin preparations to move the floating plant. If the upstream pool level is expected to reach an El. of 690.0 (U/S Gage = 20) 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 gauge, river forecasts issued by the National Weather Services, and the Corps of Engineers River Forecast System, and shall determine when to 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

SECTION 01 35 00.00 08 Page 11 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. The Contractor shall resume all work, and remobilize equipment and floating plant from its moored location when gate openings at the dam fall below 35 feet. The Contractor shall submit a Plan of Action for withdrawal of equipment and floating plant. The plan shall be submitted for the Government's review prior to the start of work. The Contractor is advised that the plan must be submitted and accepted or no work at the site will be allowed.

1.11.6.2 Plan of Action, Withdrawal of Equipment and Floating Plant

The Contractor shall perform all work in a manner that will not interfere with the duties of the lock personnel. Particular care shall be taken during all operations under this contract to prevent damage to any operating equipment or facilities at the project. The Contractor shall continuously maintain safe access to all areas of the lock project for lock operating personnel, during every phase of the work, unless otherwise directed by the Contracting Officer or their designated representative.

1.18.3.1 Restrictions to River Traffic for Delivery of Products

No interruption of traffic through the lock chambers or their approaches will be permitted. The Contractor will not be permitted any priority lockage privileges for delivery of the equipment, materials or supplies.

1.18.3.2 Installation and Removal of Dam Bulkhead

The dam bulkhead must be in place for work within the gate bay. The Contractor will not be permitted to place equipment or personnel downstream of the existing gate or perform any work on the existing gates until the bulkhead is in place. Work may be performed on the tops of the dam piers without the dam bulkhead in place. The project bulkhead used for dewatering dam bays is formed of three structural units that are stacked vertically on top of one another to form the closure. Government personnel will conduct all operations necessary to install and remove the bulkhead in a gate bay. In general, installation of the complete bulkhead takes approximately 2 to 4 hours. It is brought to the Contractors attention that once the bulkhead is installed, there will be extensive leakage in the form of spray at the joints between the individual units, and along the side seals. Leakage may occur along more than 50% of the length of the joints. The Contractor shall be responsible for furnishing and installing any tarps, sheeting, neoprene seals, or other materials that are necessary to control this leakage and keep it from the affecting the Contractor's work. The Contractor's construction schedule, submitted

SECTION 01 35 00.00 08 Page 15 in accordance with Section 01 32 01.00 08 PROJECT SCHEDULE BAR CHART, shall show the time periods that the bulkhead will be required. The Government may use the bulkhead temporarily during periods in which the Contractor does not require it. Any such Government use will be coordinated through the Contracting Officer or their designated representative. The Contractor shall give a 14 calendar day written notice to the Contracting Officer or their designated representative as to when the bulkheads will need to be placed and 14 calendar days written notice when they will require removal. Bulkheads will be set and removed from each bay only once during the contract unless otherwise approved by the Contracting Officer or their designated representative.

1.18.4 Government Service Crane and Bulkhead Hoist

The Contractor will not be permitted to use the Government's service crane or bulkhead hoist for any purposes under this contract. The Contractor shall provide all necessary cranes for lifting equipment.

1.18.5 Dam Gate Operating Schedule

The dam gate operating schedules attached at the end of this section are applicable for governing gate movements by the Government at Montgomery Locks and Dam for the operating conditions during the period of this contract. This schedule will be the basis for minimizing the effect of flow through the dam on the work at the site and maintaining customary river stages above the dam. The schedule GATE 3 OUT OF SERVICE will be in effect for the track repair at Gate 3, the schedule GATE 9 CLOSED, GATES 8 AND 10 RESTRICTED will be in effect for the replacement of Gate 9, and the schedule GATE 10 CLOSED will be in effect for replacement of Gate 10.

1.18.6 Operation of Dam Gates During Contract Work

All dam gates, except the one being replaced, shall be operable at all times during the contract period.

The Contractor should review the plan for replacement of the gates with the gate schedules provided, along with the hydrographs, rating curves, and duration curves to determine the influence that river conditions may have during the on site portion of the work under this contract.

It is noted that work within any particular bay can proceed without operating the gates in adjacent bays up to a total operational gate opening of 35 feet. If forecasted river conditions indicate additional total operational gate opening beyond 35 feet will be required, one of the gates in the adjacent bays would be opened. The Contractor's floating plant must be withdrawn from the gate bays and moored before gate operations occur in adjacent bays. See paragraph Withdrawal of Equipment and Floating Plant for additional details. As total operational gate opening approaches 35 feet, close coordination with the Lockmaster is required. The Contracting Officer or their designated representative may instruct the Contractor to move the floating plant before a total operational gate opening of 35 feet if the Lockmaster determines it necessary to maintain the safety of the project site. No additional gate operations will be conducted in support of any other work, unless specifically authorized by the Contracting Officer or their designated representative. The Contracting Officer or their designated representative will have sole authority to review all requested modifications to dam gate operations, and to what degree to accommodate active contract work. The Contractor may request in writing temporary

SECTION 01 35 00.00 08 Page 16 adjustments to gate operations to accommodate active work, but such requests shall be given to the Contracting Officer or their designated representative a minimum of 30 calendar days in advance of the requested change. Approval of such changes shall rest with the Contracting Officer who's decision shall be final. Implementation of any approved modifications to the gate operations on the date(s) requested shall be subject to river conditions, and may be delayed or altered as necessary to accommodate the prevailing river (flow) conditions and shall not be considered as a basis of a change condition. All gate operations shall be performed by Government personnel.

1.18.7 Warning Signs, Lights and Buoys

The Contractor shall be required to furnish and install all buoys, lights, signs, and other safety devices as required by Coast Guard rules and regulations. All equipment and devices shall be Coast Guard approved.

1.18.8 Contractor Coordination and Scheduling

In accordance with Section 01 32 01.00 08 PROJECT SCHEDULE BAR CHART, the Contractor shall submit a project schedule for his work to the Contracting Officer or their designated representative. All necessary adjustments in the Contractor's work schedule shall be coordinated and approved by the Contracting Officer or their designated representative.

1.19 PLACEMENT AND REMOVAL OF EMERGENCY BULKHEAD UNITS FOR PAINTING

The Government will move two bulkhead units at a time from the bulkhead storage area to permit painting of the other unit. The removed bulkhead units will be placed in a gate bay of the dam. The Government will also raise the bulkhead unit being painted to permit the Contractor to place blocking to support the bulkhead unit above the surface of the bulkhead supports in the storage area. Each bulkhead unit weighs approximately

17.2 tons. The Contractor shall furnish all blocking required to support the bulkhead unit. Blocking shall be placed in a manner to avoid compressing the rubber seals. Government personnel will conduct all operations necessary to install and remove the bulkhead in a bulkhead storage area. In general, installation of the complete bulkhead takes approximately 2 to 4 hours. The Contractor's construction schedule, submitted in accordance with Section 01 32 17 CONSTRUCTION PROGRESS SCHEDULE, shall show the time periods that the bulkhead will be required.

The Government may use the bulkhead temporarily during periods in which the Contractor does not require it. Any such Government use will be coordinated through the Contracting Officer or their designated representative. The Contractor shall give a 14 day written notice to the Contracting Officer or their designated representative as to when the bulkheads will need to be placed and 14 calendar days written notice when they will require removal. Each bulkhead unit will be set and removed only once during the contract unless otherwise approved by the Contracting Officer or their designated representative.

1.20 EMERGENCY USE OF BULKHEAD UNITS

The Contractor's attention is directed to the fact that, should a situation occur which would require use of the bulkhead at another gate bay, the Contractor will be directed take one of the following actions within four hours after notice by the Contracting Officer or their designated representative, depending on the status of gate installation:

SECTION 01 35 00.00 08 Page 17

a. If the original lift gate is in place on the gate sill with end trucks in place, The Contractor shall remove all equipment and materials that would be affected by removal of the bulkhead from the gate bay. However, items which would not be affected may remain in place provided they do not interfere with removal of the bulkhead units. No work will be permitted downstream of the existing lift gate.

b. If the new lift gate is in place on the gate sill with end trucks in place, The Contractor shall remove all equipment and materials that would be affected by removal of the bulkhead from the gate bay.

However, items which would not be affected may remain in place provided they do not interfere with removal of the bulkhead units.

Floating plant may remain in place downstream of the new gate and work which does not directly impact the gate may continue.

c. If no gate is in place, or if the gate body is not secured to the end trucks in the gate recesses, the Contract shall remove the gate body and end trucks, if present, and remove all equipment, scaffolding, and other materials from the gate bay and remove floating plant from the dam, as directed. Equipment and materials shall be removed to the extent necessary to permit the Government to install concrete gravity blocks on the gate sill downstream of the bulkhead, however, support items which do not interfere with this placement may remain in place. The Government will not be responsible for any damage to materials and equipment in the gate bay in the event they are not removed by the Contractor in a timely manner.

Payment for removal and replacement of equipment and materials to permit removal of the bulkhead units and installation of the concrete gravity blocks, if necessary, and removal and replacement of floating plant will be made as specified in Section 00 70 00 CONDITIONS OF THE CONTRACT, FAR 52.243-4 CHANGES.
