Innovation Implementation: 3D Engineered Models: Schedule, Cost and Post-Production

Advances in survey tools and technology are allowing vast amounts of 3D data to be captured safely and in less time than in the past.

As transportation agencies that have adopted 3D engineered models recognize how much data they have, they’re exploring the benefits of extending 3D applications to improve schedule (4D), cost (5D) and post-construction processes:

  • Enhanced project management – 4D modeling helps stakeholders visualize construction over the life of a project and identify potential conflicts.
  • More accurate cost estimates – 5D models enable stakeholders to evaluate costs and model cash flow for each construction phase.
  • Project life cycle record – Once a 3D model is built, it can be used for continuing maintenance, management and planning.

View the Every Day Counts summit session on 3D engineered models to learn more about 4D and 5D modeling, tools and case studies.

EDC Exchange Explains Road Diets

Boosting safety and economic growth and accommodating bicyclists were topics discussed at an April 9 EDC Exchange on road diets. Speakers from the Iowa Local Technical Assistance Program, Livable Memphis and city of Charlotte shared how a roadway reconfiguration reallocates space to safely accommodate all users, benefit operations and transit, and improve a community’s quality of life. People at 150 sites around the country participated in the exchange.

e-Construction Topic of Hawaii Exchange

Hawaii Department of Transportation and FHWA staff shared lessons learned on developing e-Construction systems during a March peer exchange. Staff of FHWA’s Federal Lands Highway discussed the Engineer Estimating, Bidding, Award and Construction System and off-the-shelf software for managing project documents. The Hawaii DOT is working with FHWA to improve existing tools and develop a strategy for implementing e-Construction systems in the state.

Michigan Summit Features Mini-Roundabouts

Mini-roundabouts were among the safety countermeasures featured at the Michigan Traffic Safety Summit. The March event in East Lansing drew more than 600 people from highway agencies, law enforcement, emergency medical response, engineering and other transportation safety-related organizations. Mini-roundabouts—circular intersections that can be used in areas with limited right-of-way-offer the safety benefits of regular roundabouts in a smaller footprint.

Texas Event Highlights e-Construction and 3D

The EDC-3 technologies of e-Construction and 3D Engineered Models for Schedule, Cost and Post-Construction processes were highlighted at a Western Association of State Highway and Transportation Officials meeting. The Texas Department of Transportation hosted the March event, which focused on lessons learned using the technologies in Florida, Texas, Utah and Washington. The Texas DOT plans to implement e-Construction statewide by the end of 2016.

Virginia Signals to Improve Traffic Movement

The Virginia Department of Transportation is installing adaptive signal control technology on the Route 29 corridor in Albemarle County to help traffic move more efficiently. Camera connections have been completed at the Hydraulic Road and Timberwood Boulevard intersections, with additional locations coming online to support real-time signal management. The agency is coordinating with the city of Charlottesville on the city’s Route 29 adaptive signal project to ensure seamless operation of signals across the city-county boundary.

Washington Hosts Bridge Workshop

Photo of WorkshopA Washington State Department of Transportation workshop covered the latest information on accelerated bridge construction techniques. The April 1 event in Tumwater focused on using ABC in high-seismic zones, project case studies, the second Strategic Highway Research Program ABC Toolkit and work on an ABC chapter for the agency’s Bridge Design Manual. The workshop was a follow-up to an earlier peer exchange on ABC.
