One aspect of e-Construction is reducing paper use, and many DOTs have successfully reduced their use of paper documents. INDOT wants to take this further by adding a data-centric approach, which focuses on the transfer of data from 3D design models to construction and then to asset management. In this presentation we discuss this initiative

3D Design Models to Construction (Data Centric Approach)Mike Jenkins, Manager INDOT MIS HMA SectionAndrew Pangallo, INDOT Construction Mgmt & Dist SupportDerek Fuller, INDOT e-Construction Specialist March 7, 2017Why e-Construction? INDOT’s main initiative was to implement and leverage 3D intelligent Computer Aided Design (CAD) models for AMG, e-Construction and Asset Management Focus was on the transition from 2D to 3D for their Construction project delivery process aligned with the Federal Highway Administration (FHWA) Every Day Counts program The main effort has been an emphasis on e-Construction that leverages 3D models in construction and provides as-built asset information to Maintenance Operations Identify many benefits to INDOT, including cost savings, and improved safety and qualityWhy e-Construction? One aspect of e-Construction is to create a document centric approach focused on reducing paper INDOT wanted to take this further by adding a data centric approach focuses on the transfer of data from 3D design models to construction and then to asset managementMission Statement The use of intelligent 3D CAD models to support the lifecycle of transportation assets (roads and bridges) that provides predictive analysis and reporting capabilities that is data driven and allows the agency to make better operational and strategic management decisions.e-Construction FHWA Every Day Counts (EDC) Initiative Paperless Construction INDOT Data Centric Approach Leverage findings from study by Purdue University, SPR-3707The Business OpportunityFigure 5.2 Asset data flow in the current practice at INDOT.Figure 5.3 The suggested data flow.3D Model Data LifecycleSurveyDesignConstructionMaintenance and OperationsPlanningAssetManagemente-Construction Current Efforts CAD Software Platform Upgrade Gap Analysis Study HP Tablets Supplied to INDOT Construction Inspectors Construction Inspection ApplicationCAD Software Platform Upgrade Completed by Bentley Systems, Inc. CAD Workspace and Design Software upgraded from SS2 InRoads to SS4 OpenRoads March – July 2016Gap Analysis Study Completed by Bentley Systems, Inc. Determine the road map for INDOT to utilize 3D CAD Models from Design in Construction and Asset Collection Completed and presented September 2016Gap Analysis Study Areas of emphasis: Automated machine Guidance (AMG) Asset Collection during constructionAMG Pilot project on I-65 near Lafayette, IN Designed by consultant in current SS2 CAD platform Bentley converted project files to SS4 OpenRoadsplatform Provided SS4 design models to the contractor Contractor analyzed the new models and provided feedback AMGAMGAMG Expected Key Benefits Ability to obtain better bids for construction Save time and money during construction Improved site design Improved safety AMG Recommendations Develop project selection criteria  Develop QA/QC specifications for 3D Models Develop specifications for electronic deliverables For AMG projects the construction staff need to be involved early in the design process Determine contractor AMG requirements Develop an organizational change planAMG Recommendations INDOT currently uses 2D plans for project delivery.  It is assumed based on other DOT’s and FHWA EDC that the following sequence will be followed: 3D models are created by INDOT’s consulting community and internal design staff, but are used to create 2D plans The above 3D models are provided for “information only.”  The 2D plans are still provided and remain the contract document Long-term, 3D models become the contract document with 2D plans provided with supplemental information Longer-term, a 3D model has all information including those previously provided on 2D plans. 2D plans are not providedAsset Collection “Experiments” Drone Imagery for Asset Collection Radio Frequency Identification (RFID) TagsDrone Imagery Experiment Details Can imagery be utilized to collect assets and assist INDOT Construction? Scheduling and liability issues prevented the use of a Unmanned Aircraft System (UAS)/drone Used handheld camera on an extension pole to take images around the Indiana Government Center complexDrone ImageryDrone ImageryDrone ImageryDrone Imagery Experiment Recommendations Using handheld camera to acquire images is a viable option for collecting small areas Control points are necessary to accurately geo-coordinate the imagery to real world Potential use in calculating areas, volumesRFID Tags Experiment Details Can RFID tags be used to uniquely identify INDOT Assets? Future asset inventory verification process?RFID TagsRFID Tags Experiment Recommendations Determine which INDOT asset types are suitable for tagging Determine if the asset owners see a benefit to tagging Conduct a Proof of Capability study on one or two asset typesHP Tablets Details Supplied to INDOT Construction Inspectors and Engineers Spring of 2016 Approximately 550 tablets HP Elite X2 tablet with Windows 10 operating systemHP Tablets Key Benefits Office software installed for easy access Wi-Fi capable for internet access Ability to complete daily tasks in the field Access documentation in the field without printing Access to Field Assistant and SiteManager applications Ability to use the camera for mobile conferencingConstruction Inspection Application Inspection ProblemDesignContractorsInspectionOperations & MaintenanceConstruction DrawingsBuilt EnvironmentRedline As-builts ProposalDesignInspectionOperations & MaintenanceContractorsBuilt Environment3D DesignContent Contractor Instructions to Inspectors Inspection Data passed to O&MData FlowWorkflowConstruction Inspection ApplicationCurrent 2D Model vs. 3D Model 2D Model 3D ModelUp to Hundreds to Thousands of pagesLimited number of design filesDifficult to find location on plans GPS on devices will auto locateMultiple pages and locations for full information on design elementCan have multiple views on one screenDesign Intent/Interpretation can be difficultDesign Intent/Interpretation clearerCross Section every 50 ft.
