CSA system shall be accessible, viewable, and maintainable by the USCG through a standard USCG workstation.

040.2.3 Configuration Baseline Definitions

040.2.3.1 General: A configuration baseline is a fixed reference configuration established by defining and recording the approved configuration documentation for a system or

CI at a milestone event or specified time.

040.2.3.2 Functional Configuration Baseline (FCB)

040.2.3.2.1 The Functional Configuration Baseline (FCB) consists of the boat’s technical, mission, operational and functional requirements, interoperability and interface characteristics, and design constraints as contained in the

Specification at contract award, including those specific items or capabilities that the contractor offered and were incorporated into the contract.

040.2.3.2.2 USCG will provide the Contractor with the FCB in the form of the

Specification.

040.2.3.3 The Allocated Configuration Baseline (ACB)

040.2.3.3.1 The Allocated Configuration Baseline (ACB) is the contractor’s design at contract award that formally breaks down the functional requirements identified in the FCB into more detailed functional requirements and interface characteristics.

040.2.3.4 The Developmental Configuration Baseline (DCB)

040.2.3.4.1 The Developmental Configuration Baseline (DCB) represents the USCG-accepted “build to” configuration of the first boat. The DCB is the responsibility of the Contractor and may be established in phases as a result of a series of detailed design reviews (DDRs) leading up to the Critical Design Review (CDR).

When the USCG has accepted a deliverable, its contents become part of the

DCB. The DCB is established when all deliverables associated with the DDRs up to the CDR have been accepted.

040.2.3.5 Preliminary Product Configuration Baseline (p-PCB)

040.2.3.5.1 The preliminary Product Configuration Baseline (p-PCB) is established by the contractor upon USCG-acceptance of the technical data that represents the configuration of the first boat. The technical data shall include contractor-formatted preliminary 3D model (in both native and STEP format), and contractor-formatted 2D drawings set (PDFs, native, and AutoCAD format) that reflects the as-built configuration.

040.2.3.6 Product Configuration Baseline (PCB)

040.2.3.6.1 The PCB is established upon adjudication of the Physical Configuration

Audit (PCA). The PCB consists of the complete technical data package as required in Attachment 3 “Technical Data Requirements”. The USCG will notify the Contractor once the PCB has been established.

040.2.3.6.2 Once the PCB is established, configuration is under USCG control. The

Contractor shall not change or modify the configuration on any boat in production or any boat already in service without approval from the USCG. This includes change or modification during the completion of warranty work.

040.2.4 Physical Configuration Audit (PCA)

040.2.4.1 The USCG will conduct a PCA on a production-representative boat to verify conformance with the product drawings.

040.2.4.2 The boat for the PCA will be designated by the USCG and will have all approved changes identified during OT&E incorporated.

040.2.4.3 The product drawings used for the PCA will have been submitted to the USCG in accordance with Attachment 3 “Technical Data Requirements” and reflect any changes incorporated into production as a result of OT&E. The Contractor shall provide one hard copy set at PCA.

040.2.4.4 The USCG will conduct an audit at the Contractor’s facility for the designated

TANB II after acceptance. The physical boat will be compared to each product drawing and each product drawing will be compared to the physical boat to validate that documented details match. Any discrepancies between the physical boat and the product drawings will be documented in a USCG-generated PCA report.

040.2.4.5 The PCA is scheduled to take no more than two weeks to complete. A Contractor representative is invited, but not required to attend. The boat shall be prepared by the

Contractor and placed in a covered facility out of the water that is accessible to

USCG. The Contractor shall provide services to the boat to allow powering up of systems.

040.2.4.6 The Contractor shall review the report and shall propose a resolution for each discrepancy. Resolution may be in the form of:

040.2.4.6.1 The drawings are correct and the boats, including those already accepted, those in production, and the PCA boat, shall be corrected.

040.2.4.6.2 The boat is correct, and the product drawings shall be revised.

040.2.4.7 The Contractor shall prepare a PCA Resolution Report that shall identify a corrective action for each discrepancy to include anticipated dates when the actions will be completed.

040.2.5 Configuration Control

040.2.5.1 Engineering Change Proposal (ECP) - The Contractor can propose changes to the contract requirements, address DMSMS/obsolete, or change to the design after the delivery of the first boat by submitting a DD Form 1692 supplied as Government

Furnished Information (GFI). ECPs shall:

040.2.5.1.1 Describe the proposed and need for the change in sufficient detail for the

USCG to ascertain if it meets the contract requirements.

040.2.5.1.2 Identify “Effectivity (identify the first boat in production on which this change will be implemented)”

040.2.5.1.3 Provide a recommendation on back fit for previously accepted boats. This includes providing kits that contain all parts necessary to complete the engineering change.

040.2.5.1.4 Identify all approved configuration and technical documentation that will require revision by listing them in block 16, “Documents Affected,” of DD Form

1692.

040.2.5.2 Request for Variance (RFV)- The Contractor may propose variance from a particular requirement of an item’s configuration baseline documentation for a specific hull or number of hulls, or for a specific period, by submitting an RFV. An RFV differs from an engineering change because it does not require a change to the configuration baseline document but merely documents the authority for the specified hulls and their configuration documentation to differ from the baseline document. A

DD Form 1694 supplied as Government Furnished Information (GFI) may be used.

The USCG will review RFVs. Upon acceptance in the form of a contract change, the

Contracting Officer will authorize the Contractor to implement the RFV.

040.2.6 Diminishing Manufacturing Sources/Material Shortages (DMSMS) and

Obsolescence
