Following the introduction, this chapter presents a four-part approach to develop the BIM strategy; define the asset information data requirements; leverage BIM during the delivery phase for improved delivery performance, along with the production of asset information for operations; and use an AIM to support operations. The broad adoption of BIM throughout a transportation agency is a journey and will require significant planning.

Within the information management lifecycle, there are important information exchange points or events when information is shared. The information exchange points or events include the start of a project delivery phase, where information is shared from the operational phase of the AIM, as well as from the new project to represent the existing conditions (especially important for renovation or repair projects)

5.3 Section 1: BIM for Asset Data Management Strategic Plan To be successful in developing a comprehensive strategy for managing lifecycle asset data across multiple projects, it is important to develop a strategic plan for collecting, storing, retrieving, and using the data. A transportation infrastructure owner should develop an asset data management plan to clearly define the important asset information that will be managed throughout the lifecycle, along with the various use cases for leveraging this information.

Typical job titles for individuals in this role within a transportation agency include standards and methods engineer, CADD services manager, automation engineer, construction manage ment systems manager, GIS manager, and asset management systems manager, or people who report directly to them. When assembling the BIM Steering Committee, consideration should be given to involving personnel with specific responsibilities and capabilities, including • One or more individuals who can champion the planning throughout the organization; • Decision-makers who have authority to grant access to resources required by the team (e.g., time, funding, personnel, and infrastructure)

The existing data environment; the as-constructed, as-found existing asset inventory; and existing data sources make up the AIM within the authoritative asset management system. Ideally, the various data sources are related and make up a comprehensive CDE for the asset information.

5.4 Section 2: Information Exchange Requirements for BIM Asset Data This section defines the steps involved for an agency to develop asset data requirements for core asset data and models. The core need to clearly define owner asset data requirements has been highlighted in multiple initiatives, including the emphasis on "beginning with the end in mind" (with the "end" being operations)

The details of these BIM uses are defined in Section 3 for plan, design, and construct phases and Section 4 for the operate phase. These use cases are divided into four categories: project delivery core, asset management core, project delivery extensions, and asset management extensions.

The information exchanges will be very detailed, along with software to transact the information using the IFC data schema managed by buildingSMART International. This schema has been adopted by AASHTO as the data schema for openBIM data exchange.

BIM in the Construction Process The core BIM uses performed within the construction process include the development of a record construction model, the use of the design model released for construction and inspection of constructed assets, authoring 4D models, laying out construction work, and use in automated machine equipment. The following are concise definitions for these construction uses: • Inspect Constructed Assets: using 3D models to verify location, elevation, and quantities of installed assets against contract requirements.

A core aspect of many of these use cases is the need to create highly detailed models with accurate geometric data, which have been defined within the BIM Forum LOD specification as LOD 400 elements. These detailed asset models will either use the design model as the base reference or, in some instances, transition the design model components into a more detailed construction model representation.

5.7 Conclusions and Observations The development of a comprehensive asset management plan using BIM across the scope of assets managed by a transportation agency will require detailed planning over multiple years. It will also require a mindset throughout the agency that places a high value on lifecycle infor mation management.
