... These standards are the basis for the modeling standards and model integrity reviews. Clearly defined naming conventions, model content, and element information yield finished products that are consistent and predictable.
From page 41...
... Specific guidance for modeling standards includes the following: • Update CADD standards to expand or revise libraries for symbology, standardized 2D and 3D objects, requirements for naming conventions, and standardized drawing production processes. Model-based design software is configured to provide libraries of intelligent, object based design elements that design teams can use as building blocks for their designs.

From page 43...
... Logical names help users effectively and efficiently identify and retrieve data when reviewing models. Most agencies have standardized file and folder naming conventions for traditional files and deliverables.
From page 44...
... Agencies should review these limitations prior to finalizing a standard naming convention. 5.2.4 Software Configuration Development and Management Design authoring software enables agencies to create a configuration that standardizes how product resources are used to design and draw objects to align with specific modeling and design standards.
From page 45...
... While IFC, associated data dictionaries, and information delivery manuals are being developed for transportation projects, agencies have an opportunity to set up their software configurations for future implementation. Building out the proper software configuration and documentation is important for the quality management process, and it allows for future automation of design standards.
From page 46...
... . This section describes review tools and job aids, such as checklists, reports, automated tools that can be used as quality artifacts, and review software, that can streamline 3D model reviews.
From page 47...
... The checklist can outline the reference architecture, file structure, file formats, and file naming conventions, or it can point reviewers to any sections of the standards where these rules are described. • Modeling standards checklist confirms that data within each discipline-specific model complies with BIM/CADD standards.
From page 48...
... Several tools are included in design authoring, design review, and con struction software that check infrastructure models against design and CADD standards. These automated tools enhance the efficiency of design teams and reviewers.
From page 49...
... 3D information models developed for transportation projects are built using complex datasets, and applying data visualizations clarifies where various types of data exist within a model. Element information like classifications, materials, pay items, build order, associated specifications, review date, or review status can be tied to display styles, indicating through color or transparency any object with the queried properties.
