... NCHRP 10-77 October 1–2, 2009 -- Workshop Report 1 Introduction The Challenge Automated machine guidance (AMG) links sophisticated design software with construction equipment to direct the operation of the machinery with a high level of precision, improving the speed and accuracy of the transportation construction process.
From page 161...
... NCHRP 10-77 October 1–2, 2009 -- Workshop Report 2 • An introductory plenary session • Several breakout sessions to discuss opportunities and obstacles for ensuring data integrity and quality results for the AMG process • Subsequent plenary sessions to review the findings of previous breakout sessions and identify further opportunities and obstacles by combining knowledge from the breakout sessions • Review of the proposed survey questionnaires The complete detailed agenda is provided in the Appendix. To start the event, participants were introduced and the research team communicated that the goals of the workshop were to develop a list of capabilities that must exist and obstacles that must be overcome to facilitate seamless electronic data transfer from the initial surveying to develop DTMs through design and construction to final inspection and verification.

... NCHRP 10-77 October 1–2, 2009 -- Workshop Report 8 Accuracy Best Practices and Inputs/Outputs This session was divided into four segments. The participants were asked to recall instances where AMG accuracy was compromised.
From page 168...
... NCHRP 10-77 October 1–2, 2009 -- Workshop Report 9 will also ask interviewees to list practices that are helpful in maintaining accuracy. The results of the interviews will be recorded for later analysis." Segment 3 – Accuracy Checks Participants were asked to propose local projects where participants can spot check for accuracy.

... NCHRP 10-77 October 1–2, 2009 -- Workshop Report 10 Segment 1 - Identifying Solutions The following processes were listed for consideration, and the participants were asked to describe each of the best practices and provide a point of contact where more information can be obtained: 1. Initial data collection (development of DTMs)
From page 170...
... NCHRP 10-77 October 1–2, 2009 -- Workshop Report 11 - Liabilities: There may be possibly higher upfront costs for software, hardware, and highly trained personnel and a possible inability to make gut-level checks for some types of design errors. Downstream personnel may be critical of design personnel for alternative designs that were not used and documented in unused parts of the model.

NCHRP 10-77 October 1–2, 2009 -- Workshop Report 37 Bid item quantity Charles Jahren (Facilitator/Recorder) Segment 1 • Projects with private owners such as developers are more advanced in using and taking advantage of data file sharing, because much of the construction is done under a design-build delivery system where there is a higher degree of integration among the owner, designer, and constructor.
From page 197...
... NCHRP 10-77 October 1–2, 2009 -- Workshop Report 38 Segment 3 No specific input from the expert contact group was collected. Segment 4 Comments provided by the expert contact group are as follows: • There is agreement that design errors are often caught in the process of developing 3D models.
From page 198...
... NCHRP 10-77 October 1–2, 2009 -- Workshop Report 39 • Some contractors double check GPS elevations with other GPS elevations. It is better to double check GPS using a completely different method, such as total station or laser.
From page 199...
... NCHRP 10-77 October 1–2, 2009 -- Workshop Report 40 One important question that should be considered is, "How should the quality of a TIN model be specified? " This needs to be communicated so that designers, contractors, and owners can have predictability about what a TIN model can be expected to deliver and how much effort is required to develop it.
