1.1. Background

SEWIP Block II provides anti-ship missile defense capabilities to the US Navy fleet. Specifically, the

AN/SLQ-32(V)6 electromagnetic warfare (EW) suite has been designed to replace and improve upon

Legacy variants of the AN/SLQ-32 EW suite. As this new system is being fielded, sustainability and maintainability of the above-deck electronics shelters have been key issues. Corrosion occurs due to the marine environment the shelters are exposed to, and coating failure occurs once corrosion begins. This corrosion, and ultimately coating failure, introduces the issue of water intrusion inside the shelters, which can be detrimental to the sensitive internal electronics. Thus, periodic refurbishment of the shelters is necessary to continue providing EW capabilities to the US Navy. This contract will provide the necessary services needed for refurbishment of the outboard shelter structure to extend the lifecycle of the shelter structure.

Accountability

All Government Furnished Property is property of the U.S. Government and shall not be transferred to any individual or agency, public or private, without the express written approval of the originating Contracting

Officer except as required for the specific performance of tasks under this contract/order. Accountability for

Government Property under this contract/order shall be managed in accordance with FAR Part 45, DFARS

Part 245 and DFARS PGI Part 245 as well as the Government Property clauses in the contract/order whether acquired by the prime or subcontractors (Contractor Acquired Property), provided by the

Government, or received directly from another commercial source as a deliverable from a Government issued contract. Additional Government Property accountability requirements are outlined in the following

Directives and Instructions and shall be adhered to as applicable:

DoDI 4161.02, Accountability & Management of Government Contract Property

DoDM 4140.01, DoD Supply Chain Material Management Procedures: Material Returns, Retention and Disposition

DoDI 5000.64, Accountability & Management of DoD Equipment and Other Accountable Property

Management

SECNAVINST 5200.43A, Government Furnished Property, Accountability and Management

NAVSEAINST 5200.15, General Equipment Accountability

4.1.1. Receipt Reporting: FAR 52.245-1(f)(1)(ii) requires the contractor to report receipt of all

GFP. Reporting of Government Furnished Property (DFARS 252.245-7005) and DoDI

4161.02, Accountability and Management of Government Contract Property Instruction requires that contractors, as part of the required receipt of any Government property, report to the DoD IUID Registry using WAWF, DLMS transactions, or direct update of the registry.

Contractors shall ensure appropriate accountable property records are maintained utilizing the data reported in the DoD IUID Registry and its integral GFP Module in the Procurement

Integrated Enterprise Environment (PIEE). At the time of reporting receipt of GFP in the GFP

Module, the contractor will also send an email notification to cran_gfpaccounta.fct@navy.mil to ensure the NSWC Crane Property Management Division is notified.

4.1.2. Shipping Notification: DoDI 4161.02 requires use of electronic transactions when transferring Government property to a contractor and upon return of property to DoD. The contractor shall use the GFP Module in PIEE when returning GFP back to the Government.

At the time of creating the shipping document to return GFP using the GFP Module, the contractor will also send an email notification to cran_gfpaccounta.fct@navy.mil to ensure the NSWC Crane Property Management Division is notified.

4.1.3. Lost, Damaged or Stolen GFP Reporting: FAR clause 52.245-1 requires the contractor to investigate and report to the Government all incidents of property loss as soon as the facts become known. DFARS 252.245-7005 further requires the contractor to report lost, damaged or stolen government property using the Property Loss functionality within the PIEE GFP

Module.

4.1.4. Excess Property Reporting: SECNAVINST 5200.43A requires unused or excess GFP be properly dispositioned as soon as the excess is identified without waiting for formal contract closeout processing. Recovering excess property from the contractor will be completed by the return of GFP back to the government via a DD-1149 or utilizing the GFP Module Plant

Clearance capability as soon as possible to ensure the property is available to fill other requirements and can potentially reduce the administrative costs of the contract. The

Government-appointed Plant Clearance Officer (PLCO) will accept or reject the request to excess GFP using the GFP Module Plant Clearance capability.

4.2. Inventory Reporting:

FAR 52.245-1 requires the contractor to periodically perform, record, and disclose physical inventory results. While the FAR clause does not define “periodically,” frequency of on-hand inventory count are in the Contract Data Requirements List (CDRL) A002 identified in this contract.

4.2.1. GFP Reporting: The contractor shall provide data deliverables IAW the listed CDRL A002 by contract and contract order number (if applicable) to provide accountability for all

Government furnished property that has been provided in support of the contract. The report shall include the fields required by the Data Item Description noted in CDRL A002, DFARS
