Breakout Group 1: Initiative 3 (3D Design Process) and Initiative 4 (Automated Machine Guidance)
3. 3D Design Process.
Issues:
o There are retraining implications for keeping current with software advances. o Ok,
o The initial deployment plan for Civil 3D does not address its full range of functionality. In addition, future enhancements by the vendor will need to be considered. Impacts of technology changes, upon both internal and external users must be addressed.
o Ok
o Future modifications to plans as the primary design deliverableshould be evaluated.
For example, consider the possible adoption of 3D models as contract documents and retention or elimination of two-dimensional views.
o How much detail to we model to?
o 3D model content and generic format standards are needed to address data exchange and downstream uses such as automated machine guidance, inspection and final quantities, and post-construction uses of 3D technology.
o Model accuracy?
o Which projects are targeted?
o Build model for contract document, produce plan from model. Stakeholders: Design, construction, CAE advisory group, CADD users group, real estate, utilities, access control, contractors and consultants, local governments and state and federal agencies.
o Vendors/Software Developers o Surveys
o Whoever can take advantage of model. Recommendations :
o Execute the existing Civil 3D deployment plan and develop an extended deployment plan.
o Appoint a stakeholder advisory group on enhancement of design deliverables to address:
o Conduct annual statewide 3D design users’ meetings.
o Development of 3D model content and generic format standards. o Evaluation of 3D models as contract documents.
Any missing recommendations that should be addressed as part of this initiative?
1) Survey Data Coordinator needs to be filled
Short-Term Goals (1-2 years) (5 minutes):
o Deployment of Civil 3D according to existing plan. o Consider Consultant need for C3D training
o Development and execution of an extended deployment plan for 3D design. o Development and implementation of annual statewide 3D design users’ conference
process. This goal is part of the charge to the study group.
o Development of non-proprietary 3D model content and format standards by the study group.
o Add 3D model deliverable option to WisDOT design contracts.
o Establishment of a date when consultants will be required to provide 3D models as a PS&E deliverable.
Long-Term Goals (beyond 2 years) (5 minutes):
o Continued execution of the extended deployment plan for 3D design.
o Evaluation of 3D models as construction contract documents by the advisory group. Timeline, Relative Levels of Effort, and Priorities:
1) Existing Civil 3D predeployment 2) C3D New User training
3) Add 3D model development option to Design 4) 3D model content and format stds
5) Establish date
4. Automated Machine Guidance (AMG).
Issues (<= 5 minutes): A message received from pilot project contractors is that they would like to have the 3D design model become a design deliverable. Current practice requires contractors to either acquire 3D models from designers if they are available or reverse-engineer model data from traditional plans and staking data. WisDOT is taking steps to remedy this with Civil 3D implementation (Initiative 3).
WisDOT wants to continue to refine the AMG specification for grading as needed. The department also desires to build upon the experience of the AMG grading specification to develop new AMG specifications for base course placement, paving, and perhaps utilities and bridges.
Ok?/Comments?
Stakeholders (<=5 minutes): Design, construction, contractors, consulting engineers, model developers, staking contractors, utilities.
Recommendations (5 minutes):
o Develop and implement a plan for monitoring and refinement of the AMG specification for grading.
o Appoint a stakeholder advisory group to develop an AMG specification for base course placement.
o Develop AMG spec for Paving
o Investigate implications of AMG for utilities, bridges, and paving to include which would be easiest to adopt. AMG for paving, bridges, and utilities might include laser augmentation for increased vertical accuracies and articulated machinery for excavation.
Short-Term Goals (1-2 years) (10 minutes):
o Monitoring and refinement of the AMG specification for grading.
o Development, testing, and implementation of an AMG specification for base course placement.
o Initiation of AMG specification development for paving, bridges, and / or utilities. o Development, testing, and implementation of an AMG specification for
Paving – consider this before looking at structures and utilities
Long-Term Goals (beyond 2 years):
o Monitoring and refinement of AMG specifications for grading and base course placement.
o Implementation of AMG specifications for paving, utilities, and bridges. Timeline, Relative Levels of Effort, and Priorities:
Breakout Group 2: Initiative 2 (DTM Data Collection and Analysis)
PURPOSE OF THIS WORKSHOP BREAKOUT
• Ensure issues, goals, recommendations, and priorities are correct. • Focus on what the priorities should be.
• Be critical of the high priorities… what really needs to be done first?
• Identify some sort of sequence for the priorities… What needs to be done before the next step?
• Do not go into details. • Guide: ~ 5 minutes per goal Stakeholders:
Technical services, engineering consultants, surveyors (public and private), project engineers,
contractors.
Responsible Parties: The sponsor will be the Technical Services Section (Ray Kumapayi) with assistance from Bureau of Project Development on use of DTMs for earthwork computations.
GOAL = Charge EFFORT PRIORITY Begin Short-Term Goals
1. Fill Regional Survey Data Coordinator Positions
Lead?
Team? Technical Services Supervisors to discuss
further.
Cindy summarized the position and why there is a need. The group agreed with the concept and importance. (Glentz) There was some concern that if the contractors are responsible for the model for machine control, is this position really needed. It was questioned whether the survey coordinator could take on some of the role. It may vary with the regional office and the workload over time. (Danielson) Custodian vs. production role should be identified. Custodian can delegate responsibility to contractor, but it should be passed backed to the agency for long-term retention. (Mahun) May lower priority until the position is better defined. Although there is a position description, there is quite a bit of discussion among the group on the focus of the position. The position is tied to more than just machine control. There is a need to have consistency throughout the process.
