Douglas Townes FHWA Resource Center 3D Engineered Models for Construction - Implementation March 14, 2013 | Washington, DC TRB Committee on Intelligent Construction Systems & Technology

2 Overview Background and Purpose Review of work to date Project approach to implementation Deployment strategies and activities Performance goals Question to the Committee

3 Background Technology representing construction projects in digital form Being used by several states in various ways Strong potential to reduce construction time Activities supported by 3D models: −Multi-disciplinary project coordination; −Clash detection analysis of design features; −Earthwork quantity computations; and, −Automated machine guidance (AMG) of heavy construction equipment.

4 Purpose To improve the quality of construction and the delivery of highway projects. The goals are to: –Improve construction documents and communication among project stakeholders; –Enhance identification and resolution of possible conflicts before construction; –Increase productivity to lower construction costs and speed up schedules; and –Improve safety on the construction site.

11 Performance Goals By December 31, 2014, FHWA Division Offices will partner with State DOT’s and/or Local Public Agencies and Federal Lands Highway Divisions will partner with Federal Agencies and/or Tribal Nations to obtain the following two independent goals: Create and apply 3D Engineered Models for Construction, consisting of a digital model representing features within the roadway prism, to construct 50 projects nationwide, and; Nationally, have 25 or more transportation agencies use 3D Engineered Models for Construction. Implementation Criteria: A transportation facility owner is considered to have implemented 3D Engineered Models for Construction if models are used on a minimum of two or more projects.
