Amendment No. 3

Bidder Questions

Q1. Currently the solicitation reads that Gate No. 3 will be delivered by December 31, 2017, Gate No. 2 by April 30, 2018, and Gate No. 1 by December 31, 2018. This presents several problems. If Gates 3 and 1 are delivered on or around December 31, then it is likely they cannot be installed at that time due to high water conditions. In fact, high water conditions could prevent unloading of the gates. Second, in order to keep crews productive, gate delivery should be advanced to no later than October 31st. Finally, if the dates stand, it is likely that both Gates 1 and 3 will be stored on barges through the high water season and Gate 2 will be stored for several months while preparatory work for setting Gate 2 is completed following Gate 3 erection.

Advancing delivery of Gate 3 to October 31, 2017 mitigates this potential storage cost. Please consider moving the delivery date for Gate 3 back to October 31, 2017 and the delivery date for Gate 1 back to October 31, 2018.

A1. No. The gate deliveries are determined from current fabrication contracts. Gate No. 3 will not be ready for delivery by October 31, 2017 as proposed. The anticipated delivery dates for the gates have been revised by Amendment No. 3 to March 1, 2018 for Gate No. 3, June 30, 2018 for Gate No. 2, and December 2, 2018 for Gate No. 1.

Q2. The current solicitation provides for a 450 day performance period and an additional 210 days if Gate 1 erection option is exercised. Assuming an August 1, 2017 Notice-to-Proceed, the completion date for the base contract would be approximately October 31, 2018. This could be problematic if river conditions prevent erection of Gate 3 from the current delivery date of 12/31/2017 until June of 2018. Please consider extending the completion time for the base contract by a minimum of 30 and preferably 60 days.

A2. No. The period of performance is reasonable with the exclusion of time associated with adverse weather and high water. Modification for adverse weather delays will be made in accordance with Addendum to Section 00800 Paragraph 00800-7 TIME EXTENSIONS FOR

UNUSUALLY SEVERE WEATHER.

Q3. Also, the additional 210 days for the Gate 1 installation option is insufficient because most of that additional time occurs during normal high water season. Please consider extending the completion time for the Gate 1 erection option to the fall of 2019, preferably October 31, 2019.

Current completion date is late spring or early summer of 2019 for this option.

A3. No. The period of performance is reasonable with the exclusion of time associated with adverse weather and high water. Modification for adverse weather delays will be made in accordance with Addendum to Section 00800 Paragraph 00800-7 TIME EXTENSIONS FOR

UNUSUALLY SEVERE WEATHER.

Questions Q4 through Q15 were addressed in Amendment 2.

Q16. How many vulcanized spliced will be made per each gate seal?

A16. There will be two vulcanized splices for each gate seal.

Questions Q17 through Q25 were addressed in Amendment 2.

The Contractor shall verify the elevations and positions of the Corps of Engineers survey controls before using them to layout the work under this contract, and shall notify the Contracting Officer of any discrepancies prior to commencing work. The Contractor shall utilize existing project monuments shown on the contract drawings to establish any additional control points for this work. The Contractor shall not use any monuments that are outside the Government's project limits to establish additional control points.

1.9 RESTRICTIONS TO RIVER TRAFFIC FOR CONSTRUCTION

Unless specifically authorized or directed, no interruption of traffic through the lock chambers or their approaches will be permitted.

1.10 PROTECTION AND MAINTENANCE OF ROAD TRAFFIC

During construction the Contractor shall maintain and protect traffic on all affected roads during the construction period except as otherwise specifically directed by the Contracting Officer. The traveling public shall be protected from damage to person and property. The Contractor shall submit his proposed traffic control plan for approval.

1.11 DAMAGE TO WORK

The responsibility for damage to any part of the permanent work shall be as set forth in Section 00700 CONTRACT CLAUSES, 52.236-7 PERMITS AND RESPONSIBILITIES. However, if, in the judgment of the Contracting Officer, any part of the permanent work performed by the Contractor is damaged by flood or earthquake, which damage is not due to the failure of the Contractor to take reasonable precautions or to exercise sound engineering and construction practices in the conduct of the work, the Contractor shall make the repairs as ordered by the Contracting Officer and full compensation for such repairs will be made at the applicable contract unit or job prices as fixed and established in the contract. If, in the opinion of the Contracting Officer, there are no contract unit or job prices applicable to any part of such work, an equitable adjustment pursuant to the Section 00700 CONTRACT CLAUSES, 52.243-4 CHANGES, will be made as full compensation for the repairs of that part of the permanent work for which there are no applicable contract unit or job prices.

Except as herein provided, damage to all work (including temporary construction), utilities, materials, equipment and plant shall be repaired to the satisfaction of the Contracting Officer at the Contractor's expense, regardless of the cause of such damage.

1.12 PROTECTION OF UTILITIES

Utilities shall be protected as specified in Section 01 50 00.10 UTILITY COORDINATION, paragraph "Protection of Utilities".

SECTION 01 35 00.00 08 Page 8

The Montgomery Locks and Dams facility shall remain in operation at all times. The Contractor shall perform his work in a manner which will not interfere with the operation of the facilities and the duties of Government 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 take all necessary precautions to ensure the safety of the workers in accordance with the applicable provisions of EM 385-1-1 . Contractor operations shall be performed in such a manner to ensure that project personnel, navigation industry personnel and the public are protected at all times.

1.14 CONDITIONS OF WORK

1.14.1 Montgomery Locks and Dam, Hours of Operation

Montgomery Locks and Dam operates 24 hours per day, seven days per week.

1.14.2 Contractor's Work Hours

There will be no restrictions imposed on Contractor's work hours for this project.

1.14.3 Coordination with Lock Operations

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.

1.14.3.1 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.

1.14.3.2 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

SECTION 01 35 00.00 08 Page 9 the Contractor's work. 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. The Contractor shall give a 14 calendar day written notice to the Contracting Officer 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.

1.14.4 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.

1.14.5 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 REPAIR OF GATE 3 WITH GATES 2 AND 4 RESTRICTED, ALL REMAINING GATES IN SERVICE will be in effect for the replacement of Gate 3, the schedule REPAIR OF GATE 2 WITH GATES 1 AND 3 RESTRICTED, ALL REMAINING GATES IN SERVICE will be in effect for the replacement of Gate 2, and the schedule REPAIR OF GATE 1 WITH GATE 2 RESTRICTED, ALL REMAINING GATES IN SERVICE will be in effect for replacement of Gate 1. The schedule CLOSE GATE 4 WITH GATES 3 AND 5 RESTRICTED will be in effect for the repair of the coatings of Gate 4.

1.14.6 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 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.

The Contracting Officer will have sole authority to review all requested

SECTION 01 35 00.00 08 Page 10 modifications to dam gate operations, and to what degree to accommodate active contract work. The Contractor may request in writing temporary adjustments to gate operations to accommodate active work, but such requests shall be given to the Contracting Officer 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.

1.14.7 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.

1.14.8 Contractor Coordination and Scheduling

In accordance with Section 01 32 17 CONSTRUCTION PROGRESS SCHEDULE, the Contractor shall submit a project schedule for his work to the Contracting Officer. All necessary adjustments in the Contractor's work schedule shall be coordinated and approved by the Contracting Officer.

1.15 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, depending on the status of gate installation:

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.

SECTION 01 35 00.00 08 Page 11

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 00700 CONTRACT CLAUSES, FAR 52.243-4 Changes. A payment will be made each time the work is directed. The time allowed for completion of work will be adjusted to include the time for the period from the Government's initial directive to stop work until the time that the Contractor is directed to resume work. Payment for repair of damage to work which has been completed will be made in accordance with Section 00700 CONTRACT CLAUSES, FAR 52.243-4 Changes.

1.15.1 Installation of Concrete Gravity Blocks

The following is provided for the Contractor's information only, all work will be performed by the Government.

a. In the event that the bulkhead must be removed, the Government will install a temporary closure in the gate bay consisting of precast concrete blocks and miscellaneous sealing items. The gravity blocks will be installed on the gate sill downstream of the bulkhead, and may extend past the bottom portion of the gate recess.

b. The Government will remove the bulkhead units and place them in another gate bay as required.

c. The Government will remove any obstructions in the gate bay and install a second set of gravity blocks in the gate bay.

d. When the temporary closure is completed, the Government will remove the bulkhead units from the gate bay and reinstall them in the gate bay in which the Contractor is working.

e. The Government will remove the gravity blocks from the gate bay in which the Contractor is working.

The Contractor shall provide personnel as necessary to adjust moorings to provide for fluctuations of pool level. A propelling unit capable of moving the floating plant must be available at all times. If the Contractor chooses to have a leased towboat or propelling unit off-site, the plant must be capable of being on-site within 4-hours notice. The written propelling unit agreement between the Contractor and the lessor documenting this requirement shall be provided to the Contracting Officer prior to mobilization of any floating plant. The agreement shall also include documentation that the propelling unit operator currently possesses a U.S. Coast Guard "Operator of Uninspected Towing Vessels" license. The Contractor shall be fully responsible for selection of floating plant which is suitable for the performance of the work under this contract.

SECTION 01 35 00.00 08 Page 12

Contractor's floating plant shall operate only within the areas of work shown on the drawings, unless such areas are modified with the approval of the Contracting Officer and Lockmaster.

1.16.2 Equipment Requirements

The Contractor shall select floating plant and towboats and propelling units of a size and capacity suitable for performance of the work under this contract. Towboats and propelling units shall have sufficient horsepower capacity to control the floating plant used, considering the size and draft of the plant, for the expected river velocities and wind conditions. The minimum size of towboats shall be 1,000 horsepower. The Contractor shall submit a plan of all floating plant, floating plant based equipment (i.e. cranes, derricks), temporary operating systems (i.e.

generators, compressors, welding machines, etc.), and other appurtenant features which he will have present during the contract period. The Contractor shall use sketches, diagrams, and narratives to indicate location of all floating plant-equipment. The Contractor shall use manufacture catalog information or other suitable data to describe the specific equipment to be used. The Contractor shall also indicate the methods and procedures that will be used to deliver materials, supplies and equipment via floating plant.

All equipment and devices shall be Coast Guard approved.

1.16.4 Maintenance of Floating Plant

The Contractor shall maintain all floating plant equipment in good working condition throughout the contract period.

1.16.5 Mooring of Floating Plant

The Contractor shall be responsible for all mooring of floating plant.

When not in use, the Contractor's floating plant shall be securely moored. The Contractor shall also be solely responsible for providing personnel in order to adjust mooring lines as required by the prevailing river conditions.

Floating plant may remain downstream of the dam during non-working time with consideration of the exceptions noted in paragraphs "Operation of Dam Gates during Contract Work," and "Withdrawal of Equipment and Floating Plant," herein. Without exception, all floating plant and equipment shall be removed from any position downstream of the dam when the total dam gate openings exceed 40 feet.

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-1135 However, this plant must be completely removed and secured at an off site location that is no closer than 1 mile from the site, by the time the upper pool river gauge reaches 20.0.

SECTION 01 35 00.00 08 Page 13

Withdrawal or relocation of floating plant shall be completed within four

(4) hours of any notice from the Contracting Officer or Lockmaster.

1.16.6 Suspension of River Traffic and Construction

1.16.6.1 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. 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. 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.

1.16.6.2 Plan of Action, Withdrawal of Equipment and Floating Plant

The Contractor shall prepare and submit a Plan of Action for withdrawal of equipment and floating plant. The plan shall detail the procedures for withdrawal of equipment and floating plant in the event that suspension of river traffic and work is imminent.
