  19. Mitchell Interchange • 14 Bridges - Includes 3 tunnels • 29 Retaining Walls • 44 Sign Bridges • 7 Noise Barriers • 1,375,000 CY of Common Excavation • 10 miles of mainline and system ramps

  20. Design Level of Complexity Correspondence: Items Logged

  21. Lessons Learned Owner’s perspective Interface and integration is the key: • Structures (size, type, procurement) • Roadway (access, grading, drainage) • Storm sewer (depth, temp connections) • Electrical systems (aesthetics, plans) • Utilities (new vs. old, relocated, as-builts) • Preliminary stage work (season, quality) • Weather (markings, stage changes)

  22. Program Delivery: IPD - BIM Building Information Modeling (BIM) • Collaboration • 3D Visual • Prefabrication • Improved Design Documents • Quantity extraction • Visual scheduling • Phasing Plans • Coordination • E-Turnover/Archives

  23. Use of 3D design for integration “clash” detection • Quality Control – Tool • Clash Detection, Reveals Interface Issues • Reduce Project Risk – Cost/Schedule • CPM Schedule - Near Critical Tasks – Cascading Impact • Visualization Tool • Public, Stakeholders • Technical – • Contractor/Engineer • Utilities

  24. Tunnels – Building Information Modeling (BIM)

  48. 3D/4D design tools Interface Emphasis • Staging – Project/Program • Temporary Roadways • Temporary drainage connections • Preliminary phase construction • Temporary Fills, Drainage, Lighting,…. • Partial Construction • Access in and out of work zone • Staging areas

  49. Quality plans address…. • Look for and resolve Interface Issues • Within Project • Between Projects • Manage Earthwork holistically • Deliver Aggressive Schedule with consideration for weather
