(End of clause)

252.232-7077 LIMITATION OF GOVERNMENT’S OBLIGATION (APR 2014)

(a) Contract line item(s) CLINS 001 through 013 (excluding any unexercised options) are incrementally funded.

For this/these item(s), the sum of $70,000,000 of the total price is presently available for payment and allotted to this contract. An allotment schedule is set forth in paragraph (j) of this clause.

(b) For item(s) identified in paragraph (a) of this clause, the Contractor agrees to perform up to the point at which the total amount payable by the Government, including reimbursement in the event of termination of those item(s) for the Government’s convenience, approximates the total amount currently allotted to the contract. The Contractor is not authorized to continue work on those item(s) beyond that point. The Government will not be obligated in any event to reimburse the Contractor in excess of the amount allotted to the contract for those item(s) regardless of anything to the contrary in the clause entitled “Termination for Convenience of the Government.” As used in this clause, the total amount payable by the Government in the event of termination of applicable contract line item(s) for convenience includes costs, profit, and estimated termination settlement costs for those item(s).

(c) Notwithstanding the dates specified in the allotment schedule in paragraph (j) of this clause, the Contractor will notify the Contracting Officer in writing at least ninety days prior to the date when, in the Contractor’s best judgment, the work will reach the point at which the total amount payable by the Government, including any cost for termination for convenience, will approximate 85 percent of the total amount then allotted to the contract for performance of the applicable item(s). The notification will state (1) the estimated date when that point will be reached and (2) an estimate of additional funding, if any, needed to continue performance of applicable line items up to the next scheduled date for allotment of funds identified in paragraph (j) of this clause, or to a mutually agreed upon substitute date. The notification will also advise the Contracting Officer of the estimated amount of additional funds that will be required for the timely performance of the item(s) funded pursuant to this clause, for a subsequent period as may be specified in the allotment schedule in paragraph (j) of this clause or otherwise agreed to by the parties. If after such notification additional funds are not allotted by the date identified in the Contractor’s notification, or by an agreed substitute date, the Contracting Officer will terminate any item(s) for which additional funds have not been allotted, pursuant to the clause of this contract entitled “Termination for Convenience of the Government.”

(d) When additional funds are allotted for continued performance of the contract line item(s) identified in paragraph (a) of this clause, the parties will agree as to the period of contract performance which will be covered by the funds. The provisions of paragraphs (b) through (d) of this clause will apply in like manner to the additional allotted funds and agreed substitute date, and the contract will be modified accordingly.

(e) If, solely by reason of failure of the Government to allot additional funds, by the dates indicated below, in amounts sufficient for timely performance of the contract line item(s) identified in paragraph (a) of this clause, the Contractor incurs additional costs or is delayed in the performance of the work under this contract and if additional funds are allotted, an equitable adjustment will be made in the price or prices (including appropriate target, billing, and ceiling prices where applicable) of the item(s), or in the time of delivery, or both. Failure to agree to any such equitable adjustment hereunder will be a dispute concerning a question of fact within the meaning of the clause entitled “Disputes.”

(f) The Government may at any time prior to termination allot additional funds for the performance of the contract line item(s) identified in paragraph (a) of this clause.

(g) The termination provisions of this clause do not limit the rights of the Government under the clause entitled “Default.” The provisions of this clause are limited to the work and allotment of funds for the contract line item(s) set forth in paragraph (a) of this clause. This clause no longer applies once the contract is fully funded except with regard to the rights or obligations of the parties concerning equitable adjustments negotiated under paragraphs (d) and (e) of this clause.

(h) Nothing in this clause affects the right of the Government to terminate this contract pursuant to the clause of this contract entitled “Termination for Convenience of the Government.”

(i) Nothing in this clause shall be construed as authorization of voluntary services whose acceptance is otherwise prohibited under 31 U.S.C. 1342.

(j) The parties contemplate that the Government will allot funds to this contract in accordance with the following schedule below. The amounts listed in FY25-FY27 are notional amounts used for bidding purposes and do not reflect the final negotiated contract total (these will be updated prior to award):

FY21: On execution of contract $ 70,000,000

FY22: 15 December 2021 $ 214,000,000

FY23: 16 January 2023 $ 390,000,000

FY26: 15 January 2026 $ 200,000,000

FY27: 15 January 2027 $ 152,477,644

52.216-4 Economic Price Adjustment-Labor and Material (JAN 2017)

(a) The Contractor shall notify the Contracting Officer if, at any time during contract performance, the rate of pay for labor (including fringe benefits) or the unit prices for material shown in the “Economic Price Adjustment Schedule” (attached hereto and included in the Contractor’s proposal submitted on June 22, 2021) either increase or decrease. The Contractor shall furnish this notice within 60 days after the increase or decrease, or within any additional period that the Contracting Officer may approve in writing, but not later than the date of final payment under this contract. The notice shall include the Contractor's proposal for an adjustment in the contract unit prices to be negotiated under paragraph (b) of this clause, and shall include, in the form required by the Contracting Officer, supporting data explaining the cause, effective date, and amount of the increase or decrease and the amount of the Contractor's adjustment proposal.

(b) Promptly after the Contracting Officer receives the notice and data under paragraph (a) of this clause, the Contracting Officer and the Contractor shall negotiate a price adjustment in the contract unit prices and its effective date. The Contracting Officer will make the adjustments at quarterly intervals throughout the contract performance. The Contracting Officer shall modify this contract (1) to include the price adjustment and its effective date and (2) to revise the labor rates (including fringe benefits) or unit prices of material as shown in the Schedule to reflect the increases or decreases resulting from the adjustment. The Contractor shall continue performance pending agreement on, or determination of, any adjustment and its effective date.

(c) Any price adjustment under this clause is subject to the following limitations:

(1) Any adjustment shall be limited to the effect on unit prices of the increases or decreases in the rates of pay for labor (including fringe benefits) or unit prices for material shown in the Schedule. There shall be no adjustment for-

(i) Supplies or services for which the production cost is not affected by such changes;

(ii) Changes in rates or unit prices other than those shown in the Schedule; or

(iii) Changes in the quantities of labor or material used from those shown in the Schedule for each item.

(2) No upward adjustment shall apply to supplies or services that are required to be delivered or performed before the effective date of the adjustment, unless the Contractor’s failure to deliver or perform according to the delivery schedule results from causes beyond the Contractor’s control and without its fault or negligence, within the meaning of the Default clause.

(3) Adjustments will occur at quarterly intervals throughout the contract performance.

(4) The increases in any contract unit price made under this clause shall not exceed 100 percent of the original unit price. There is no percentage limitation on the amount of decreases that may be made under this clause.

(d) The Contracting Officer may examine the Contractor’s books, records, and other supporting data relevant to the cost of labor (including fringe benefits) and material during all reasonable times until the end of 3 years after the date of final payment under this contract or the time periods specified in subpart 4.7 of the Federal Acquisition Regulation (FAR), whichever is earlier.

A minimum of 90 days prior to a docking or undocking the contractor must submit a letter notifying the contracting officer to any changes outside of the contract documents made or planned to be made to the structures that make up the basin prior to the docking or undocking. Those structures include: Berth 11, Berth 1, South Clouse Wall, DD1W entrance, and West Closure Wall. Changes outside of the contract documents may require back up calculations depending on the nature of the changes. Calculations are required to show capability of the superflood basin to support the structural loads and exfiltration impacts to the basin. These changes may also require interim testing evolutions of superflood prior to the completion of the phase. If required, testing and certification approval must occur 30 days prior to the completion of the phase.

1.4.4.1 Partial Demobilization During Vessel Movements

Seven days prior to a docking or undocking milestone partial demobilization is required to clear the route from existing Dry Dock 1 through the basin and out through the P-310/Dry Dock 1 West entrance structure. This includes, but is not limited to, the space in the basin, Berth 1, and the center wall.
