Implementation of GPS controlled highway construction equipment - phase II

Abstract

During 2006, WisDOT and the Construction Materials and Support Center at UW-Madison worked together to develop a specification and QC/QA procedures for GPS machine guidance on highway construction grading operations. These specifications and procedures are intended for incorporation in contracts on two to five pilot projects during the 2007 construction season. The 2006 work, and the 2007 pilot projects are the first two steps in a phased implementation plan that includes refinement of the specification and procedures after the 2007 pilots, additional pilots during 2008, and potential statewide implementation of optional GPS machine guidance for grading on 2009 contracts. To be effective, the goals, objectives, and methods for data collection and analysis for the 2007 pilot projects must be well-articulated; the project sites must be carefully selected; and a set of deliverables and management plan for coordination of the effort must be developed.
