ISO 15489-1:2016 is a useful reference for agencies establishing records management controls, policies, and responsibilities for digital quality artifacts and 3D models used as part of the letting documents. It is also a helpful resource for analyzing changing business contexts as an agency implements digital project delivery.

An effective digital preservation strategy accounts for and mitigates the impact of multiple threats that could compromise the accessibility and usability of digital materials over time. While agencies typically have existing policies for records retention periods, such policies may need to be amended to ensure that information stored in 3D models and other digital formats remains accessible over the full retention period.

• Authenticity: A digital object is what it purports to be. Metadata and proper records management of contextual information -- like standards for digital data -- are essential to preserving the identity and understandability of digital records.

An agency's records management policy would likely need to specify that versions of each discipline-specific model and associated quality artifacts from each milestone review should be retained. Agencies would also need to store historical versions of the associated standards, such as CADD, model development, and LOIN standards, so that a model's content can be interpreted in the future.

Some general reasons why digital records of 3D models need to be created and carefully managed include • Legislative requirements (including state sunshine laws) ; • Department policy; • Legal accountability; • Supporting the needs of the public and stakeholders, when feasible and within policy [e.g., questions about the limits of right of way (ROW)

This section discusses various approaches to digital quality artifacts, focusing on document-based, 2D plan–based, and 3D model software options. 3.3.1 Document-Based Quality Artifacts Digital document-based artifacts include forms, reports, and spreadsheets.

Unless the checker creates saved views in the design model, the back checker and revisor may struggle to recreate issues highlighted in the design model. Reports can also be generated by design software.

Using 2D CADD files, or 3D CADD files in a 2D view in CADD software, eliminates the need to create plan sheets. Reviewers can also manipulate 3D design data to obtain a plan sheet view, but this is cumbersome.
