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

  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.

  5. Review of Work to Date • Consultant SAIC contracted,served as SME • Established FHWA core team and stakeholders technical panel • FHWA field staff webinar training last Sept • Regional Summits – Fall 2012: • 2 sessions, introduction and applications • Received input on deployment strategies - 20+ activities identified • Implementation Plan

  6. Project Approach to Implementation • Stakeholders driven • 3-pronged approach • Targeted to various state levels of implementation • Designed to maximize participation

  7. Deployment Strategies

  10. 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.

  11. Digital Modeling … … a look towards the future

  12. 4D Modeling - Scheduling

  13. 5D Modeling – Cost Estimating

  14. Question to the TRB Committee • What steps should FHWA be taking now toprepare itself for the deployment of 4D and 5D modeling in FY14 and FY15?
