SPECS 000-099 000-3

042.3 REFERENCED DOCUMENTS

042.3.1 Definitions

042.3.1.1 "Contract drawings" are drawings which delineate design features of the boat. No departure from details of a contract drawing shall be made without specific approval of the Government. Minor rearrangements to a space defined by a Contract Drawing (± 6 inches for bulkheads except main transverse and main longitudinal bulkheads, ± 10 inches for accesses and ± 12 inches for equipment and furniture and other items within a space) may be made, to clear interferences or accommodate changes in sizes of those components, provided that operability, maintainability, man-machine interfaces, and service envelopes are not adversely affected.

042.3.1.2 "Guidance drawings" are drawings identified as "Guidance Drawing" which illustrate design features of the ship. A guidance drawing does not necessarily depict, nor is it intended that it depict, features and details of the systems and structures to which it relates. It serves the purpose of providing information which, when utilized in conjunction with applicable specification requirements, contract drawings, project-peculiar drawings, and other information, will result in an acceptable design.

Departure from specific details may be made without approval, provided an acceptable design results. Guidance Drawings will not necessarily be updated or revised to reflect future modifications or changes to these specifications.

042.3.1.3 "Expanded Ship Work Breakdown Structure" (ESWBS) is a method of ship weight and system classification defined by NAVSEA 0900-LP-039-9010. Reference to ESWBS or SWBS in these specifications shall mean the Expanded Ship Work Breakdown Structure.

042.3.1.4 "Industry standards" are documents promulgated by recognized non-Government organizations (such as ANSI or ASTM) that establish engineering and technical limitations and applications for items, materials, processes, methods, design, and engineering practices.

042.3.1.5 "Primary references" and "sub tier references": Any referenced document which is directly cited for use or application by an identifying number or name in these specifications or in any contract drawing, is a primary reference for each particular use or application for which it is so cited. Any document which is cited in a primary reference, or in a document referenced therein, is a subtier reference. A document which is a subtier reference in one application may be a primary reference in another application when it is cited directly

042.3.1.6 Where any primary or sub-tier reference uses language such as: “recommends, should, or similar,” this shall be interpreted as a “shall” requirement in the reference document itself.

042.3.2 In the event that the Contractor discovers any error or inapplicability in the identification of reference documents, the Contractor shall notify the Contracting Officer within 5 days of that discovery.

042.4 EFFECTIVE ISSUE

042.4.1 The effective issue of a reference document refers to that issue of a reference document which forms a part of these specifications. Whenever first tier references are identified within these specifications by revision or amendment, that issue shall be the effective issue for the particular use or application cited.

These specifications do not prescribe effective issue requirements for sub-tier references. Sub-tier references shall be those in effect on the date of the first tier referenced document version used. The effective issue of references not specifically identified by issue or amendment shall be that in effect on 5 January 2026 unless otherwise specified. The effective issue of contract drawings, guidance drawings and project peculiar documents is the revision listed in Table I. Where no revision is indicated, the original issue is intended.

042.5 ORDER OF PRECEDENCE

042.5.1 Order of Precedence of requirements within the Expanded Ship Work Breakdown Structure Sections of the Homeland Security Cutter- Light (HSC-L) Specification is as follows:

042.5.1.1 Requirements within a SWBS Section applicable to the entire HSC-L (for example, SWBS Section 070 - General Requirements for Design and Construction) state the broadest requirements and apply

SPECS 000-099 000-4

to systems and equipment, unless otherwise specified in the more detailed SWBS Sections, in which case the detailed SWBS Section requirements apply.

042.5.1.2 Specific requirements within a lead, 1-digit SWBS Section (for example, a SWBS Section which includes the general or common requirements for a number of similar systems, such as SWBS Section 500 - Auxiliary Systems, General) are the next broadest category of requirements, and shall apply to systems and equipment in its grouping as well as other ship systems where applicable, unless otherwise specified in detail system SWBS Sections.

042.5.1.3 Specific requirements within a 2-digit SWBS Section (for example, a SWBS Section which includes the details of a particular system such as SWBS 530, Fresh Water Systems) are the next broadest category of requirements and shall apply to systems and equipment in its grouping, unless otherwise specified in detail system SWBS Sections.

042.5.1.4 Specific requirements within a detailed, 3-digit SWBS Section (for example, a SWBS Section which includes the details of a particular system such as SWBS 533, Potable Water Systems) are the most detailed requirements. Requirements in these detailed system SWBS Sections apply for the system covered in the detailed SWBS Section.

042.5.1.5 The omission in one SWBS Section of details covered in another SWBS Section shall not be considered a conflict.

042.5.1.6 In the event that two or more requirements of equal precedence are found to apparently conflict, the Contractor shall formally identify the conflict to the Government for clarification, or correction of the specifications, as appropriate.

042.5.2 Order of Precedence of Documents

042.5.2.1 In case of conflict between the Specification and referenced documents, the following order of precedence applies:

042.5.2.1.1 Contract Drawings.

042.5.2.1.2 HSC-L System Specification

042.5.2.1.3 Primary references

042.5.2.1.4 Contract Guidance Drawings.

042.5.2.1.5 Sub-tier references.

042.5.2.2 The order of precedence only applies in the event there is a conflict between requirements.

042.5.2.3 In the event that requirements are found to apparently conflict, the Contractor shall formally identify the conflict to the Government for clarification, or correction of the specifications, as appropriate.

042.5.3 The following drawings and form a part of these specifications to the extent specified herein.
