SECTION E – INSPECTION AND ACCEPTANCE

52.246-12 INSPECTION OF CONSTRUCTION (AUG 1996)

(a) Definition. “Work” includes, but is not limited to, materials, workmanship, and manufacture and fabrication of components.

(b) The Contractor shall maintain an adequate inspection system and perform such inspections as will ensure that the work performed under the contract conforms to contract requirements. The Contractor shall maintain complete inspection records and make them available to the Government. All work shall be conducted under the general direction of the Contracting Officer and is subject to Government inspection and test at all places and at all reasonable times before acceptance to ensure strict compliance with the terms of the contract.

(c) Government inspections and tests are for the sole benefit of the Government and do not—

(1) Relieve the Contractor of responsibility for providing adequate quality control measures;

(2) Relieve the Contractor of responsibility for damage to or loss of the material before acceptance;

(3) Constitute or imply acceptance; or

(4) Affect the continuing rights of the Government after acceptance of the completed work under paragraph (i) of this section.

(d) The presence or absence of a Government inspector does not relieve the Contractor from any contract requirement, nor is the inspector authorized to change any term or condition of the specification without the Contracting Officer’s written authorization.

(e) The Contractor shall promptly furnish, at no increase in contract price, all facilities, labor, and material reasonably needed for performing such safe and convenient inspections and tests as may be required by the Contracting Officer. The Government may charge to the Contractor any additional cost of inspection or test when work is not ready at the time specified by the Contractor for inspection or test, or when prior rejection makes reinspection or retest necessary. The Government shall perform all inspections and tests in a manner that will not unnecessarily delay the work. Special, full size, and performance tests shall be performed as described in the contract.

(f) The Contractor shall, without charge, replace or correct work found by the Government not to conform to contract requirements, unless in the public interest the Government consents to accept the work with an appropriate adjustment in contract price. The Contractor shall promptly segregate and remove rejected material from the premises.

(g) If the Contractor does not promptly replace or correct rejected work, the Government may—

(1) By contract or otherwise, replace or correct the work and charge the cost to the Contractor; or

(2) Terminate for default the Contractor’s right to proceed.

(h) If, before acceptance of the entire work, the Government decides to examine already completed work by removing it or tearing it out, the Contractor, on request, shall promptly furnish all necessary facilities, labor, and material. If the work is found to be defective or nonconforming in any material respect due to the fault of the Contractor or its Subcontractors, the Contractor shall defray the expenses of the examination and of satisfactory reconstruction. However, if the work is found to meet contract requirements, the Contracting Officer shall make an equitable adjustment for the additional services involved in the examination and reconstruction, including, if completion of the work was thereby delayed, an extension of time.

(i) Unless otherwise specified in the contract, the Government shall accept, as promptly as practicable after completion and inspection, all work required by the contract or that portion of the work the Contracting Officer determines can be accepted separately. Acceptance shall be final and conclusive except for latent defects, fraud, gross mistakes amounting to fraud, or the Government’s rights under any warranty or guarantee.

SECTION F – DELIVERIES OR PERFORMANCE

52.211-12 LIQUIDATED DAMAGES—CONSTRUCTION (SEPT 2000)

(a) If the Contractor fails to complete the work within the time specified in the contract, the Contractor shall pay liquidated damages to the Government in the amount of $1,545.00 for each calendar day of delay until the work is completed or accepted.

(b) If the Government terminates the Contractor’s right to proceed, liquidated damages will continue to accrue until the work is completed. These liquidated damages are in addition to excess costs of repurchase under the Termination clause.

(End of clause)

52.211-13 TIME EXTENSIONS (SEPT 2000)

Time extensions for contract changes will depend upon the extent, if any, by which the changes cause delay in the completion of the various elements of construction. The change order granting the time extension may provide that the contract completion date will be extended only for those specific elements related to the changed work and that the remaining contract completion dates for all other portions of the work will not be altered. The change order also may provide an equitable readjustment of liquidated damages under the new completion schedule.

52.236-15 SCHEDULES FOR CONSTRUCTION CONTRACTS (DEVIATION JAN 2026)

(a)

(1) Within five days after the work commences on the contract or another period of time determined by the

Contracting Officer, the Contractor shall prepare and submit to the Contracting Officer for approval a practicable schedule showing the order in which the Contractor proposes to perform the work, and the dates on which the

Contractor contemplates starting and completing the work (including acquiring materials, plant, and equipment).

(2) The schedule shall be in the form of a progress chart of suitable scale to indicate appropriately the percentage of work scheduled for completion by any given date during the period.

(3) If the Contractor fails to submit a schedule within the time prescribed, the Contracting Officer may withhold approval of progress payments until the Contractor submits the required schedule.

(b) The Contractor shall continually update the actual progress in the schedule and shall submit it to the Contracting

Officer by the means prescribed in the contract for transmittals or as directed by the Contracting Officer.

(c)

(1) If the Contractor falls behind the approved schedule, the Contractor shall take steps necessary to recover lost time and execute in accordance with the approved schedule, without additional cost to the Government.

(2) Such steps may include increasing the number of shifts, overtime operations, days of work, and/or the amount of construction plant.

(3) The Contractor shall submit, for approval, supplementary schedule(s) that demonstrate how the lost time will be recovered.

(d) If the Contractor does not recover the lost time, the Contracting Officer may determine that the Contractor is not prosecuting the work with sufficient diligence to ensure completion within the time specified in the contract. Upon

(a) The Contracting Officer may order the Contractor, in writing, to suspend, delay, or interrupt all or any part of the work of this contract for the period of time that the Contracting Officer determines appropriate for the convenience of the Government.

(b) If the performance of all or any part of the work is, for an unreasonable period of time, suspended, delayed, or interrupted (1) by an act of the Contracting Officer in the administration of this contract, or (2) by the Contracting Officer’s failure to act within the time specified in this contract (or within a reasonable time if not specified), an adjustment shall be made for any increase in the cost of performance of this contract (excluding profit) necessarily caused by the unreasonable suspension, delay, or interruption, and the contract modified in writing accordingly. However, no adjustment shall be made under this clause for any suspension, delay, or interruption to the extent that performance would have been so suspended, delayed, or interrupted by any other cause, including the fault or negligence of the Contractor, or for which an equitable adjustment is provided for or excluded under any other term or condition of this contract.

(c) A claim under this clause shall not be allowed—

(1) For any costs incurred more than 20-days before the Contractor shall have notified the Contracting Officer in writing of the act or failure to act involved (but this requirement shall not apply as to a claim resulting from a suspension order); and

(2) Unless the claim, in an amount stated, is asserted in writing as soon as practicable after the termination of the suspension, delay, or interruption, but not later than the date of final payment under the contract.

NOTICE TO CONTRACTORS - CONTRACTOR PERFORMANCE ASSESSMENT REPORTING

SYSTEM (DEC 2015)

1. FAR 42.1502 directs all Federal agencies to collect past performance information on contracts. The Department of the Interior (DOI) has implemented the Contractor Performance Assessment Reporting System (CPARS) to comply with this regulation. One or more past performance evaluations will be conducted in order to record your contract performance as required by FAR 42.15.

2. The past performance evaluation process is a totally paperless process using CPARS. CPARS is a web-based system that allows for electronic processing of the performance evaluation report. Once the report is processed, it is available in CPARS for Government use in evaluating past performance as part of a source selection action.

3. We request that you furnish the Contracting Officer with the name, position title, phone number, and email address for each person designated to have access to your firm's past performance evaluation(s) for the contract no later than 30-days after award. Each person granted access will have the ability to provide comments in the Contractor portion of the report and state whether or not the Contractor agrees with the evaluation, before returning the report to the Assessing Official (AO). Information in the report must be protected as source selection sensitive information not releasable to the public.

4. When your Contractor Representative(s) are registered in CPARS, they will receive an automatically generated email with detailed login instructions. Further details, systems requirements, and training information for CPARS is available at https://www.cpars.gov/.

5. Within 60-days after the end of a performance period, the AO will complete an interim or final past performance evaluation, and the report will be accessible at https://www.cpars.gov/.

a. Contractor Representatives may then provide comments in response to the evaluation, or return the evaluation without comment.

b. Your comments should focus on objective facts in the AO's narrative and should provide your views on the causes and ramifications of the assessed performance.

Solicitation No.

National Park Service (NPS) – Denver Service Center (DSC) KNRI 257081 – Riverbank Stabilization

c. All information provided should be reviewed for accuracy prior to submission.

d. If you elect not to provide comments, please acknowledge receipt of the evaluation by indicating "No comment" in the space provided, and then selecting “Accept the Ratings and Close the Evaluation”.

e. Your response is due within 60-calendar days after receipt of the CPAR. On day 15, the evaluation will become available in CPARS marked as “Pending” with or without comments and whether or not it has been closed.

f. If you do not sign and submit the CPAR within 60-days, it will automatically be returned to the Government and will be annotated: "The report was delivered/received by the Contractor on (date). The Contractor neither signed nor offered comment in response to this assessment."

6. The following guidelines apply concerning your use of the past performance evaluation:

a. Protect the evaluation as source selection information. After review, transmit the evaluation by completing and submitting the form through CPARS. If for some reason you are unable to view and/or submit the form through CPARS, contact the CO for instructions.

b. Strictly control access to the evaluation within your organization. Ensure the evaluation is never released to persons or entities outside of your control.

c. Prohibit the use of or reference to evaluation data for advertising, promotional material, pre-award surveys, responsibility determinations, production readiness reviews, or other similar purposes.

7. If you wish to discuss a past performance evaluation, you should request a meeting in writing to the Contracting Officer no later than seven (7)-days following your receipt of the evaluation. The meeting will be held in person or via telephone or other means during your 60-day review period.

8. A copy of the completed past performance evaluation will be available in CPARS for your viewing and for Government use supporting source selection actions after it has been finalized.
