About 3D Engineered Models

Every Day Counts

Three-dimensional Engineered Models for construction (or just 3D models) are among a few select technologies being promoted by the FHWA Every Day Counts program. Our focus is on helping owner-agencies, designers, and construction contractors with little or no experience in 3D engineered models get started in implementing this technology.

The Oregon Coordinate Reference System: A Surveying Approach for Supporting Geospatial-Based Technologies in Transportation Applications New (.pdf, 1 mb) This case study highlights the Oregon Department of Transportation's journey in setting the groundwork for better use of survey data for both engineering and geographic information system workflows, with a focus on the Oregon Coordinate Reference System implementation. It serves as a resource for understanding the geospatial foundation for 3D engineered model-based technologies.

How-to Guidance

cover

This Guide for Selecting Projects Suitable for 4D Modeling New (.pdf, 2 mb) offers STAs new insights to managing project risk, optimizing resources, communicating with the public, and account transparently for construction expenditures by combining a 3D model with a project schedule to create a simulation of construction activities that represents the 4D model.

  • Web Based Training

    FHWA's Office of Infrastructure Construction Management Team is offering highly engaging Web-based training (WBT) on 3D Engineered Models for Construction, which is made up of four 120-minute modules. While all of the modules explore a new topic within 3D modeling, they are also designed with enough recurring content to serve as individual learning experiences.

  • Workshops

    Selected State transportation agencies are hosting a 3D workshop highlighting: State of the practice - procedures and technology; Practical demonstrations highlighting beneficial uses of the technology; Construction quality assurance methods; Implementation strategies for success; Answers to attendees' questions on issues and implementation

  • Webinar Series

    In EDC-2 and EDC-3, the FHWA created two webinar series to increase overall awareness and general education of transportation professionals in uses of 3D engineered models in all phases of project delivery that include the areas of planning, data collection and management, design, construction, operations and maintenance of highway facilities. EDC-2 emphasized 3D engineered models for design and construction, while EDC-3 promoted the broader use of 3D models and digital data to further advance other application areas.
