© 2015, Fiatech Presentation Takeaways/Deliverables Key Takeaways Understand benefits of having 3D utility data available in a design & construction model Grasp limitations of the utility data collection and modeling processes Compelling Image Here (If Possible)

© 2015, Fiatech Opportunities Being Addressed Utility Risks in Construction Inaccurate records/mapping & unknown utilities Construction scheduling dependent on utility relocations & installation being complete on time Civil structure & utility design based on (poor/wrong) available information Coordination issues during relocation design & construction Safety!

© 2015, Fiatech Constraints & Barriers to Effective Utility Modeling Buried utilities not visible from surface; Not Lidar WYSIWYG Utility materials can be difficult to detect Soil & environment can foil geophysics New utility installations occurring daily Records obsolete & rarely georeferenced “as-builts” = “as-imagined” Depths difficult to obtain w/o testholes Constraints & Barriers 3dbc8ddb970d-pi

© 2015, Fiatech Anticipated Benefits of 3D Utility Model Compelling Image Here Central Communication Tool for all utility- related information across disciplines Comprehensive utility info clearinghouse: SUE QL, Type, Size, Owner, Material, QL A (testhole) information Easy retrieval of info for entire DB Team: Profiles, elevations, stakeout, testholes Enables strategic vs. reactionary decisions Fewer redesigns, change orders & schedule impacts; enhanced communication O+M applications for future utility installations Handover to owner Approach & Benefits Realized

© 2015, Fiatech Building & Maintaining the Model Bentley SUE package, Power InRoads/GeoPak Based on QLB fieldwork with QLD metadata Depths assumed from TXDOT Utility Accommodation Rules (UAR) Continual attribute updating based on testhole program & fieldwork (location, depth, size, material) New installations added as constructed Utilities taken out of service and/or removed are updated in model Approach & Benefits Realized

© 2015, Fiatech Summary & Implementation Value still being calculated on this project (construction begins this month) High quality SUE program necessary for best model inputs & uses; many assumptions still necessary to build model Requires savvy design/build Team that is proficient & familiar with 3D modeling across disciplines SUE Software has limitations on metadata access across platforms & systems that need improvement Start SUE Early & Set Expectations!
