SECTION C - DESCRIPTION/SPECIFICATION

DRAFT STATEMENT OF WORK

C.1 SCOPE

The Naval Surface Warfare Center, Carderock Division coordinates the manufacture and delivery of a variety of nickel aluminum bronze (NAB) canister configurations for the Virginia-Class propulsor manufacturing program. The Contractor will be responsible for the fabrication of NAB canisters in multiple configurations. The VA class classifies the canisters into two types, “Regular” and “LDVA”. There are multiple configurations within the Regular classification. The Regular configurations are R1, R2, R3, and S1L. The LDVA is the largest canister and is referred to as R4 or R4L. Regardless of the configuration, each canister consists of the following individual components: body tubes, top caps, bottom caps, masses, and shim rings.

C.3 REQUIREMENTS

C.3.1 Machining of Individual Piece Parts

Government furnished material (GFM) will be provided to the Contractor for machining of body tubes, top caps, bottom caps and masses (hereby known as piece-parts) within two weeks of Delivery Order award in accordance with section C.6 of the Statement of Work. Upon receipt of the GFM, the Contractor shall inspect the material to verify material properties are in accordance with references C.2.1 through C.2.4 and Table 1.

The Contractor shall machine these piece-parts in accordance with reference C.2.1 for all types (Regular and LDVA) canisters. The Contractor shall procure any material not provided as GFM (mild steel, ASTM A108) required to fabricate R4L shim rings in compliance with reference C.2.11.

The Contractor shall separately machine the piece-parts in compliance with references C.2.5 through C.2.14.

Excess raw material and piece parts shall be marked, stored, and secured for the duration of the contract pending disposition instructions from the Contracting Officer Representative (COR) or Contracting Officer. All piece-parts for assembly shall be cleaned with acetone to remove residual cutting lubricants prior to packaging for shipping per the drawing requirements referenced in C.2.6 and C.2.14.

Upon completion of piece-part machining, the Contractor shall package the finished parts for delivery in accordance with the preservation and packaging notes in each drawing to the Government at the address provided below. The Contractor shall be responsible for the condition of all parts until receipt inspection and final acceptance at destination is completed. Shipping address to NSWCCD:

Naval Surface Warfare Center 9500 MacArthur Blvd.

West Bethesda, MD 20817

C.3.1.1 Inspection Criteria

For each order under this contract, the Contractor shall inspect the first five consecutive parts and last five consecutive parts for quality control to verify against drawing tolerance specifications. The dimensions for each of those ten total parts shall be recorded to four decimal places and provided as production certification, Contract Data Requirements List (CDRL) A001. All remaining parts of the production run shall have 100% inspection of all dimensions, also to four decimal places, but actuals need not be recorded.

C.3.1.1.a The measurement equipment shall have proof of calibration and be traceable to a nationally recognized standard. Substantiating documentation shall be appended to CDRL A002.

C.3.1.1.b The measurement uncertainty associated with each device must be within +/-20% of the feature tolerance that it is being used to verify.

A dimensional deviation occurring during the production run shall require a process evaluation and a repeat of section C.3.1.1 in its entirety. The production certification for each lot, CDRL A001, shall specify which parts required reevaluation and rework.

C.4. MANAGEMENT

The Contractor shall manage its personnel to perform the requirements of this contract and shall submit a Contractor’s Progress, Status and Management Report, CDRL A002. In addition, The Contractor shall develop and maintain a planned versus actual progress schedule, CDRL A003.

C.5 DELIVERABLES

The Contractor shall deliver the piece parts in the specified quantities as identified in each Delivery Order.

Delivery of completed piece parts shall be split equally into three lots with no penalty for early delivery.

The following is an example for the completion of 600 piece parts:

C.6 GOVERNMENT FURNISHED MATERIALS

For the all raw material (mild steel, ASTM A108) that is not required for the R4L shim rings identified via DWG PR15023, Items 1-7, the Government will provide material for each part up to the finished length plus .2 inches excess for each part. While the Government is providing GFM in accordance with Attachment 0002, any additional material beyond the GFM shall be provided by the contractor at no additional cost to the Government. The Contractor remains responsible for all raw material (mild steel, ASTM A108) for the R4L shim rings identified via DWG PR15023. The contractor shall notify the Contracting Officer’s Representative of any excess Government owned material for disposition instructions.

For planning purposes, shipments of Tungsten Alloy will be approximately 5-8 bars and is 3’x3’x2’. NAB tube and rod may be shipped in lengths varying between 10' and 12', and will be packaged on skids in bundles of 4-7.
