ensure a consistent approach from source document identification through DIS issuance. They should
address and control responsibilities associated with document preparation, review and approval
processes, and the long-term maintenance and control of completed documents. They should address
the activities necessary to implement the DR program, including the following:
Personnel selection, orientation, and training
Project interfaces (organizational and programmatic)
Project control (schedule and milestones control)
Identification of potential source documents
Technical review of source documents
Verification and technical validation
Discrepancy resolution and open-item management
DIS development (including format and content guide, and layout guide)
DIS review and approval
DIS field validation
DIS maintenance and revision
Identification and retrieval of design information are divisible into two distinct subfunctions: (1)
identification and retrieval of the source document that might contain design information and (2)
extraction of the design information contained in the identified source documents Each of these
subfunctions calls for unique experience and expertise. Identification and retrieval of source documents
involves identifying the document types and specific documents that contain design information, locating
the documents, and retrieving and cataloging the documents. Extraction of design information
presupposes technical expertise in recognizing and classifying various types of such information.
Identification and retrieval of design information is accomplished through three phased activities: formal
review, smart search, and comprehensive search. These phases correlate with increasing design detail:
the formal review concentrates on summary-level design documents; the smart search, the outputs of
the design process; and the comprehensive search, the remaining relevant source documents,
particularly those establishing the design basis for the design requirements. These phases differ
primarily in scope. During each phase, after the source documents are identified and retrieved, the
source documents are reviewed to extract the relevant design information, both design requirements
and design basis. The approach to design information extraction should be essentially the same,
regardless of the source document. The cumulative result of these activities at any stage constitutes the
Best Available Design Information.
Facilities should identify pilot DR activities to gain experience and to solidify methods. For example, a
selected file room could be reviewed initially to identify and retrieve source documents. Then, this effort
could be critiqued to improve the methods used before going on and applying the approach to other
document locations. Similarly, pilot extraction efforts on selected documents could be useful in refining
extraction methods and procedures. Appropriate implementation procedures could be prepared and
then tested by pilots to control each activity. Further, where adequate design information is not
available, individual facilities may also identify supplementary activities for design reconstitution. For
example, facility walkdowns to gather nameplate data could be undertaken, if necessary and beneficial.
Concurrent with DR efforts, the normal design process continues to generate new and revised design
requirements and the design basis. These normal design activities also contribute to the Best Available
Design Information. Controls should be in place to ensure that ongoing design process efforts and DR
