Deliverable Type: Infographic

Overview: A high-level digital workflow infographic that shows work (business) processes within and across all phases of the asset life cycle and how these processes connect to each other for a select number of project types and one project delivery type. The specific project types that will be targeted include reconstruction, major rehabilitation, and resurfacing, and the focus project delivery type is the design-bid-build approach. Each of the project types will have a separate graphic based on the distinctions of those projects. As part of the infographic development, the metadata associated with the process steps and sub-steps documented in the infographic such as key trigger events and information exchanges, general information requirements that necessitate these exchanges (tasks, people and tools/technologies responsible for the exchanges will also be documented in a structured manner using a database-oriented approach. The developed digital workflow infographics will serve as the roadmap for digital delivery.

Deliverable Type: Infographic

Overview: Several legal concerns affect the use of Building Information Management (BIM), especially as it pertains to exchanging data in digital workflows. The legal challenges are organized into the following categories: Compensation, Contractual Language and Conditions, Intellectual Property, Data Security, Interoperability, Liability, State and Local Statutes and Regulations, and Risk Allocation. The specific risk and legal challenges vary based on the ultimate goal for using BIM. Because the goals and destination of the data are critically important, they relate heavily to the specific information exchanges that occur, such as the design to construction exchange in Model as the Legal Document (MALD). Ultimately, a BIM process should clarify the risks and liabilities of the stakeholders within the project. However, some aspects of our contracts and workflows will need to change to take full advantage of BIM. Given the state of the industry, there is a need to formally identify and categorize the legal challenges faced by Department of Transportation (DOT) organizations employing BIM. DOTs can then prioritize them for further investigation, understand what mitigation techniques are in place to address them, and identify additional gaps for further study.

Advanced field tools/technologies including mobile devices/applications, terrestrial/aerial LiDAR, point cloud meshing and unmanned aerial systems (UAS) supplementing real time kinetic (RTK) GNSS rover, robotics total station (RTS) and photogrammetry are key to leveraging lifecycle BIM model-based processes in construction and maintenance project delivery at DOT agencies.

Deliverable Type: Report

Overview: bSI’s Industry Foundation Classes (IFC) Standard and its role in advancing BIM for Infrastructure, with a focus on IFC 4.3 (the latest version of this standard) as it applies to road infrastructure (ifcRoad). Descriptions of classifications available in this open international standard for modeling of highway road infrastructure assets, and planning, survey, design, construction, and asset management use cases considered by bSI in the development of the ifcRoad standard.

In addition to the classifications, other data modeling constructs available in the ifcRoad (i.e., property sets, enumerations, spatial relationships etc.) are described. The IFC overview describes the strengths, weaknesses, and the opportunities for further improvement in IFC that have been identified by bSI and the industry stakeholders.

The relationships between ifcRoad and the Level of Development (LOD) and the Model Element Breakdown (MEB) standards being developed through AASHTO’s JTCEES are highlighted.

Deliverable Type: Report

Overview: Report describes what data governance is and how it can be used to govern the data that is utilized for creating “data models” in the BIM framework. The importance of data governance for BIM data modeling and data exchanges is explained from the following perspectives:

• Importance of establishing and governing the standard terms, information requirements and definitions, data modeling objects, classifications, properties (attributes), data modeling parameters/rulesets based on open standards.
• Importance of establishing and governing data dictionaries at the enterprise level.
• Importance of standard-based data modeling (creation/collection/acquisition) and data exchange
• Importance of tracking and governing what highway asset data is created/captured using which application/tool (or data system) and which application/tool serves as the single source of truth for each of the asset data attributes (properties).
• Importance of aligning and governing the pick-lists items (enumerations) across the different data management applications and aligning them with open-standards based enumerations.
• Importance of establishing and governing consistent data quality assessment rules for models
• Importance of identifying, enabling, and governing the data exchanges or data integrations across applications use at the enterprise level.
