INTRODUCTION

1.0.1 The Naval Surface Warfare Center - Philadelphia Division (NSWCPD) is the Department of Defense entity responsible for research and development, test and evaluation, engineering and fleet support organization for the Navy’s ships, submarines, military watercraft and unmanned vehicles. This requirement is for NSWCPD Code 422 Diesel Engine Branch, which is responsible for diesel engines within the U.S. Navy Fleet, including the SSBN/GN 726 and SSN 688 ship classes.

1.0.2 This contract is for non-personal services. It does not create employment rights with the U.S. Government whether actual, inherent, or implied. By agreeing to perform the services described in these specifications, the Contractor acknowledges that he/she is not, and shall not become, an employee of the U.S. Government. The Contractor further agrees that he/she shall not bring any cause of action in any forum claiming that he/she has become an employee of the U.S. Government.

1.0.3 The Contractor shall, pursuant to the Government’s right and obligation to inspect, accept, or reject the work, comply with such general direction of the Contracting Officer, or the duly authorized representative of the Contracting Officer as is necessary to ensure accomplishment of the contract objectives.

1.0.4 Government / Contractor Relationship

The services to be delivered under this Task Order are non-personal services and the parties recognize and agree that no employer-employee relationship exists or will exist under the Task Order between the Government and the Contractor's personnel. Therefore, it is in the best interest of the Government to provide both parties a full understanding of their respective obligations.

The Contractor employees shall identify themselves as Contractor personnel by introducing themselves or being introduced as Contractor personnel and displaying distinguishable badges or other visible identification for meetings with Government personnel. In addition, Contractor personnel shall appropriately identify themselves as Contractor employees in telephone conversations and in formal and informal written correspondence

Contractor personnel under this Task Order shall not engage in any of the inherently Governmental functions listed at FAR Subpart 7.5 or DFARS Subpart 207.5.

Employee Relationship:

The services to be performed under this Task Order do not require the Contractor or its personnel to exercise personal judgment and discretion on behalf of the Government. Rather the Contractor's personnel will act and exercise personal judgment and discretion on behalf of the Contractor.

Rules, regulations, directives, and requirements that are issued by the U. S. Navy and NSWCPD under its responsibility for good order, administration, and security are applicable to all personnel who enter a Government installation or who travel on Government transportation. This is not to be construed or interpreted to establish any degree of Government control that is inconsistent with a non-personal services contract.

Inapplicability of Employee Benefits: This Task Order does not create an employer-employee relationship. Accordingly, entitlements and benefits applicable to such relationships do not apply.

Notice: It is the Contractor's, as well as the Government's, responsibility to monitor Task Order activities and notify the Contracting Officer if the Contractor believes that the intent of this Section has been or may be violated.

The Contractor shall notify the Contracting Officer in writing via letter or email within three (3) calendar days from the date of any incident that the Contractor considers to constitute a violation of this Section. The notice should include the date, nature, and circumstances of the conduct; the name, function, and activity of each Government employee or Contractor official or employee involved or knowledgeable about such conduct; identify any documents or substance of any oral communication involved in the conduct; and the Contractor's estimated date when, absent a response, cost, schedule or performance will be impacted.

The Contracting Officer will, within five (5) calendar days after receipt of notice, respond to the notice in writing. In responding, the Contracting Officer will either:

Confirm the conduct is in violation and when necessary direct the mode of further performance, Countermand any communication regarded as a violation, Deny that the conduct constitutes a violation and when necessary direct the mode of further performance, or In the event the notice is inadequate to make a decision, advise the Contractor what additional information is required, and establish the date by which it should be furnished by the Contractor.

1.1 BACKGROUND

1.1.1 In FY2027, USS Columbia (SSN 771), USS Nebraska (SSBN 739), and USS Rhode Island (SSBN 740) Emergency Diesel Generators (EDG) require renewals to current Original Equipment Manufacturer (OEM) specifications.
