CLAUSES INCORPORATED BY FULL TEXT

HQ B-2-0004 EXPEDITING CONTRACT CLOSEOUT (NAVSEA) (DEC 1995)

(a) As part of the negotiated fixed price or total estimated amount of this contract, both the Government and the Contractor have agreed to waive any entitlement that otherwise might accrue to either party in any residual dollar amount of $500 or less at the time of final contract closeout. The term "residual dollar amount" shall include all money that would otherwise be owed to either party at the end of the contract, except that, amounts connected in any way with taxation, allegations of fraud and/or antitrust violations shall be excluded. For purposes of determining residual dollar amounts, offsets of money owed by one party against money that would otherwise be paid by that party may be considered to the extent permitted by law.

(b) This agreement to waive entitlement to residual dollar amounts has been considered by both parties. It is agreed that the administrative costs for either party associated with collecting such small dollar amounts could exceed the amount to be recovered.

TECHNICAL SPECIFICATION FOR MOTOR-OPERATED PILOT VALVES (MOPVS)

1. SCOPE

1.1. PURPOSE

This specification defines the requirements applicable to the design and construction of the motor-operated pilot valve (MOPV) for use aboard US Navy ships. This document contains the specific performance, functional, maintenance and programmatic requirements for the MOPV.

References to the “MOPV” or the “valve” within this specification refer to the entire valve assembly, actuator, and any auxiliary devices supplied by the Contractor, unless otherwise specifically stated.

1.2. BACKGROUND

The MOPV is intended to replace the existing solenoid-operated pilot valves (SOPVs) which are installed in Aqueous Film Forming Foam (AFFF) and Washdown Counter Measure (WDCM) Systems.

The MOPV will provide two control functions, as a 4-port master MOPV and a 3-port service MOPV. The 4-port master MOPV will be used to initiate AFFF concentrate flow and firemain flow for mixing and disbursement to AFFF systems aboard ship. The 3-port MOPV serves as the local disbursement valve for either firemain flow or the AFFF mixture. The MOPV specified herein shall be a 4-port valve with capability to function as a 3-port valve.

See Section 3.3.21 and the figure cited therein for the Port and Flow configurations and the Open/Close designations.

1.3. LIABILITIES

The Contractor shall accept responsibility and liability for the effect on the baseline design of all design changes instituted, recommended, and approved. The Contractor shall evaluate all changes and modifications to the basic design to ensure that the strength, performance, service life, safety, interchangeability, maintainability, reliability and operation of the entire valve and components are not compromised as a result of the modification or change. In the event that this evaluation reveals compromise in any of the above, the Contractor shall immediately inform Naval Surface Warfare Center, Philadelphia Division (NSWCPD) in writing of the results of the evaluation and shall provide a recommendation, including a cost estimate and schedule for the work needed to recover from the compromised condition.

1.4. SUBMITTALS

All Contractor submittals, including technical deliverables, shall be to NSWCPD as defined in the purchase order or herein. All Contractor requests for interpretation or clarification of any purchase order specification, requests for repair welding authorizations (when required) and requests for acceptance of a nonconforming condition shall be submitted to the applicable Navy contracting officer. The minimum required deliverables are defined in the applicable sections of this specification. Deliverables required by this and other specifications shall be submitted to NSWCPD for approval. The submittals shall identify the purchase order number and purchase order item number for which the data is submitted. To this purpose the following definitions apply:

(a) US Navy - United States Navy

(b) Contractor – Manufacturer, Corporation or Agency accepting a contract to develop or provide the material described herein.

(c) Government – All official agencies of the US Government

(d) NAVSEA – Naval Sea Systems Command

(e) NSWCPD – Naval Surface Warfare Center, Philadelphia Division

2. APPLICABLE DOCUMENTS

2.1. SPECIFICATIONS, STANDARDS, AND PUBLICATIONS

The following documents form a part of this specification to the extent specified herein. However, all revisions or effective dates of specifications referenced within the Technical Specification, shall take precedence over any newly released revisions, including effective issue dates defined in Section 2.2.

2.2. EFFECTIVE DATE

Unless otherwise specified herein, the revision of the applicable Government or commercial specification cited shall be the revision in effect in at the time of contract award. The ASSIST database at http://assist.daps.dla.mil is the official source for all Defense Standardization Program documents and contains the most current information. The ASSIST database should be used as a guide for determining which issue of specifications, standards, and handbooks, and amendments to these documents is in effect on this date. Where a specification is cancelled and a replacement is identified in the cancellation notice, the last revision prior to cancellation shall be used until US Navy approval is obtained that the replacement specifications, with any necessary supplemental requirements or modifications, is adequate.

2.3. USE OF LATER REVISIONS OF MATERIAL SPECIFICATIONS

Except in cases where a specific revision of a specification is invoked by this procurement specification or other contractual document, the Contractor may elect to use material procured to later revisions than the effective revision of the material specification. This election is allowed provided that the material form, mechanical properties and composition of the material will not be altered, and that neither the number nor the scope of any required destructive or nondestructive tests or other inspections will be reduced or the acceptance criteria degraded.

Material specifications are defined as those specifications that identify the requirements for mechanical properties, material composition, testing, and inspection of the materials used in construction for the component. This includes specifications for metals in all forms, lubricants, non-metallics, such as gaskets and O-rings, and fasteners.

In the event that the Contractor elects to use material procured to a later revision of a specification, the applicable material certification packages, whether provided with the component hardware or retained on record at the Contractor’s facility, must be supplemented by appropriate documentation. This documentation must clearly identify the substitution that was made, identify the affected individual piece part number(s), and provide the following certification: “The Contractor hereby certifies that the material provided is in the same form and meets the same mechanical property and material composition requirements as would have been the case had the material been procured to the effective revision of the specification with any invoked additional ordering requirements.

Furthermore, neither the number nor the scope of any required destructive or non-destructive tests or other inspections were reduced, or the acceptance criteria degraded, by this substitution.”
