    8. History Originally we used

    9. Why Site? “Site Modeler enables fast, dynamic development of site models and easy management of the many changes that occur on projects” – GEOPAK Help File

    10. SERIOUSLY Very Efficient Tool Improved Layouts for Complex Areas Consider Roadway Alignment Interaction / Constructability Evaluate Interchange Interior Drainage Determine Wall Requirements Improved Input for Bridge Layout

    11. SERIOUSLY More Accurate Construction Cost

    12. Simplicity of Site Three Components Involved – Elements Objects Models

    13. Process Utilized Import Base Object (typically existing ground TIN) Establish design elements using MicroStation Assign elevations to elements using Site tools Create Site objects containing groups of elements Create a Site model containing multiple objects

    14. What not to D0 Don’t - Bring in a 300 meg TIN File

    15. Level of Detail 5% - 10% Design Level Useable Horizontal & Vertical Alignments Concept Level – Cross Sections Project Footprint Higher Level of Detailed Construction Cost than Traditional Corridor Studies This is not Final Design or Preliminary Design

    16. Where to Start First thing needed is a base to import No, Aerials and Chartpak Tape won’t work for this. Survey? Yea, that’s happening. If you’re lucky. Good old USGS straight from the magical internet Now we have something to import and hopefully has more relief than an aerial photo.

    17. Next Step Alignment and profile using Road or Site

    18. Welcome to Your New Best Friend

    19. Next Step Alignment and profile using Road or Site Now for the real fun “Composite Section” A few things to remember Don’t Add to Active Model After the composite dialog box is complete, close it or Always Check the object the composite section is being imported into!

    20. Composite Section What’s to use to generate the section? Search for Elements or Feature Parallel Elements Slope from Elements Cells

    22. Corridor Studies

    30. Urban Freeway Concept Development US 20 Capacity Improvement Study – Dubuque, IA Concept Development – Estimated $104M Construction Cost Upgrading 10 miles of US 20 to Freeway

    31. GEOPAK Site & US 20 Dubuque, IA PROJECT BACKGROUND Environmental Impact Statement (EIS) Design Level – 10% Deliverables Horizontal and Vertical Concept Level Cross Sections Detailed Construction Cost Impacts!!

    32. GEOPAK Site & US 20 Dubuque, IA WORKFLOW First look Horizontal and Vertical Develop concept level model and cross sections with Site Analyze interaction with other alignments Determine impacts Optimize Horizontal and Vertical

    33. GEOPAK Site & US 20 Dubuque, IA Tools used to create a Model Composite Sections - 2 main features utilized Cells (typical sections) Develop typical section cell library Search (non typical sections, i.e. ramp gores and turn lanes Create the elements in MicroStation with unique symbology

    34. GEOPAK Site & US 20 Dubuque, IA Typical Sections Barrier Sections Curb and Gutter

    35. GEOPAK Site & US 20 Dubuque, IA Be a line string Created form left to right

    36. GEOPAK Site & US 20 Dubuque, IA Used for non-typical Sections Ramp Gores Turn lanes

    37. GEOPAK Site & US 20 Dubuque, IA Elements must – Have different symbology for each element to be searched for Continuous without breaks May be lines, linestrings or complex chains

    38. GEOPAK Site & US 20 Dubuque, IA Creating a 3d model for an Elevated Urban Freeway Using Composite Sections

    39. GEOPAK Site & US 20 Dubuque, IA Import Horizontal and Vertical into an object

    40. GEOPAK Site & US 20 Dubuque, IA Open Composite Section Dialogue Box

    41. GEOPAK Site & US 20 Dubuque, IA Use Select to find the desired cell

    42. GEOPAK Site & US 20 Dubuque, IA Side Toggle Right Left

    43. GEOPAK Site & US 20 Dubuque, IA Non-Typical Section

    44. GEOPAK Site & US 20 Dubuque, IA Set gore and shoulder symbology

    45. GEOPAK Site & US 20 Dubuque, IA Add Cell for Outside Barrier

    46. GEOPAK Site & US 20 Dubuque, IA Complete Composite Section for Right Section Side

    47. GEOPAK Site & US 20 Dubuque, IA The power of Site is the ability to modify alignments quickly

    48. GEOPAK Site & US 20 Dubuque, IA Now run Composite Sections

    49. GEOPAK Site & US 20 Dubuque, IA With Composite Sections Complete an object is created

    50. GEOPAK Site & US 20 Dubuque, IA Adjust the cut/fill slopes for the object to the desired side slope

    51. GEOPAK Site & US 20 Dubuque, IA Insert the object into the Model

    52. GEOPAK Site & US 20 Dubuque, IA Insert the object into the Model

    53. GEOPAK Site & US 20 Dubuque, IA Review the object by using the Analysis Profile tool in Site

    54. GEOPAK Site & US 20 Dubuque, IA Frontage Roads Slip Ramps Cross Roads

    55. GEOPAK Site & US 20 Dubuque, IA Cross Sections Based on the model The model itself Reviewing the roadways boundary

    56. GEOPAK Site & US 20 Dubuque, IA Identify preliminary wall locations by the model

    57. GEOPAK Site & US 20 Dubuque, IA Identify preliminary wall locations by the model & The Analysis Profile Tool

    58. GEOPAK Site & US 20 Dubuque, IA Identify preliminary wall lengths by the model

    59. GEOPAK Site & US 20 Dubuque, IA Identify preliminary wall heights Adding the wall to the model

    60. GEOPAK Site & US 20 Dubuque, IA Drape the wall on the backslope of the frontage road

    61. GEOPAK Site & US 20 Dubuque, IA Use Element Side Slope to project up to ground line

    62. GEOPAK Site & US 20 Dubuque, IA Review the wall by using the Analysis Profile tool in Site

    63. GEOPAK Site & US 20 Dubuque, IA The same procedure can be used to determine wall requirements for depressed freeway sections

    64. GEOPAK Site & US 20 Dubuque, IA Developing Cross Sections form the Model

    65. GEOPAK Site & US 20 Dubuque, IA Developing Cross Sections form the Model

    66. GEOPAK Site & US 20 Dubuque, IA Developing Cross Sections form the Model

    67. Rural Freeway System Interchange Nebraska Highway 2 & US 77 - Lincoln, NE Concept Development – Preliminary Design New South Beltway around the City of Lincoln

    68. GEOPAK Site & N2 - US 77 Lincoln, NE PROJECT BACKGROUND Signed Environmental Impact Statement (EIS) Preliminary Design Design Level – 30% Fresh Look at System Interchanges Deliverables Horizontal and Vertical Cross Sections Detailed Construction Cost

    69. GEOPAK Site & N2 - US 77 Lincoln, NE How does Site aid in system interchange layout?

    70. GEOPAK Site & N2 - US 77 Lincoln, NE Interaction Between Roadway Alignments

    71. GEOPAK Site & N2 - US 77 Lincoln, NE Interaction Between Roadway Alignments

    72. GEOPAK Site & N2 - US 77 Lincoln, NE Interchange interior drainage

    73. GEOPAK Site & N2 - US 77 Lincoln, NE Improved Bridge Input

    74. GEOPAK Site & N2 - US 77 Lincoln, NE Improved Bridge Input

    75. GEOPAK Site & N2 - US 77 Lincoln, NE Preliminary Wall Locations

    76. Things for the Future Improved Stability with V8 Use Criteria Files with Object Slope Design Allow Use of Reference Files for Element Search Extent Option to Close Boundary at Begin/End of Composite Section Incorporate Superelevation Shapes into Site Object Improved Cogo Alignment Modification Tools Automated Handling of Bridge Areas
