• Engineering Project Information
• Surveyed 3 different times (1992, 2001,
  2003-2004) over the course of 12 years and each
  survey had additional surveys within the time
  periods they were done. Translated survey into
  InRoads Survey via CDOT translator program. It
  took approximately 200 hours to translate the
  survey into MicroStation. The survey was
  translated for graphics uses only (approximately
  95 complete) because there were to many
  unresolved issues, due to different types of data
  involved in the different surveys. (conventional
  - coordinated base, conventional - azimuth based,
  RTK etc..). As a result no dtm was generated so
  the existing terrain was converted into InRoads
  from the original AutoCAD PICS files.
• Consultant designed project to FIR using AutoCAD
  and MX.
• CDOT translated project to AutoCAD and InRoads
• Each team member created their own levels and
  features so there was little consistency.
• Team members learning InRoads.
• No training or support available.
• Became a First Adopter project and translated
  project to MicroStation and InRoads.
• Team members started using standard levels and
  features.
• Each time the configuration was updated team
  members had to update levels and features.

• Roadway Engineering Design Team
• Varied from 2 to five people for differing
  lengths of time and include Bob Hays, Dan
  Marcucci, Helen Peiker, Gerald Fielding, and
  Megan Christensen (student intern).
• With a team of people coming and going the
  project was broken into parts where each person
  could easily work on their area while allowing
  others to work on theirs (SH119, Ramps A, B, C,
  D, SH 52, local roads, and bike paths). All team
  members were located in one office so constant
  communication and updating of team members and
  files could take place.
• Survey Team
• Varied over the years and include Mark Guerrero,
  Ed Warwick, Charlie Northrup, Bill Aldorfer,
  Helen Peiker, Lee Groves, Jerry Johnson, Art
  Lacombe

• Roadway Engineering Programming Challenges
• Complicated typical sections which included
  pavement, curb gutter, sidewalks, concrete or
  metal beam guardrail, drainage ditches, and walls
  all starting, stopping, and varying in width at
  different locations.
• Multiple walls and levels of walls due to tight
  right-of-way.
• Raised medians crossing back and forth across
  centerline with varying widths.
• Curb and Gutter transitions from catch to spill
  type.
• Mainline super elevation rotating one direction
  while an auxiliary lane is developed that super
  elevates the other direction. Or gores that have
  several break points (edge of travel for mainline
  and ramp).
• Toes that needed to tie into existing ground at a
  certain locations.
• Tying together mainlines, ramps, bike paths,
  gores, local roads, structures, and walls into
  one dtm.
• Connecting ramp and mainline features at
  intersections.
• Modeling Subgrade Features for Cross Sections and
  Volumes where various alignments converge and
  diverge (mainlines, ramps, and bike paths).
• Creating the variable slope and width depressed
  median.

• Roadway Engineering Programming Challenges
• Complicated typical sections which included
  pavement, curb gutter, sidewalks, concrete or
  metal beam guardrail, drainage ditches, and walls
  all starting, stopping, and varying in width at
  different locations.
• Used a variety of InRoads options
• Creating an alignment from template segments
  using Import Geometry from Graphics to tie into.
  (daylight slopes, gores, supers going different
  directions)
• Created an alignment for the template segments to
  go and intersectd on a certain slope. (RE Walls)
• Station offset command in the modeler. (widening
  of a segment)
• Transition between templates (spill to catch curb
  gutter, segment widening)
• Created one surface and had another surface
  interface into it. (depressed medians)

• Multiple walls and levels of walls
• Created separate wall alignments (horizontal and
  vertical) for top of walls.
• Developed a decision table to create the bottom
  of the walls.
• Tied segments from Ramps and mainlines by

  Volumes where various alignments converge and
  diverge (mainlines, ramps, and bike paths).

• Modeling Subgrade Features for Cross Sections and
  Volumes where various alignments converge and
  diverge (mainlines, ramps, and bike paths)
• Shoulder feature of the ramp would be copied into
  the bike path surface using copy portion of
  surface.
• Bike path surface the feature would be partially
  deleted, giving only the area desired.
• Use the generate longitudinal feature tool to
  offset both vertically and horizontally to obtain
  a subgrade surface that ties into the ramp
  subgrade surface.

• Identified feature in original survey that the
  roadway needed to tie into.
• Used a decision table to have roadway template
  tie into that survey dtm Features X, Y, Z
  coordinates.

• Raised medians crossing back and forth across
  centerline with varying widths.
• Created horizontal alignments (left and right) of
  median edge of oil using MicroStation.
• Created horizontal alignment of medians by using
  the Import Geometry from Graphics command.
• Ran a dummy template with super elevation along
  CL of roadway with dummy segments following
  median alignments with fixity being variable
  width, resulting with the feature having the
  correct elevations.
• Import the resulting feature as the main
  horizontal and vertical alignments by using the
  Import Geometry from Graphics command.
• Created templates (left, right, catch and spill
  curb gutter, travel lanes, and shoulders) and
  ran them along the new edge of oil alignments
  creating top of template.

  elevates the other direction. Or gores that have
  several break points (edge of travel for mainline
  and ramp).
• Took the feature that was created from the
  mainline template and created an alignment using
  the Import Geometry from Graphics command.
• Ran template along new alignment with proposed
  super elevation and roadway library to create the
  auxiliary lane with the correct widths and
  elevations.

• Connecting ramp and mainline features at
  intersections.
• To create feature between edge of oils of
  adjoining roadways used Fillet Feature command
• Used the Partial Delete Command to trim out the
  middle.
• Created decision table to run along that feature
  to create curb and gutter, sidewalk and slopes.
  Note This does not work for toes on small radius
  curves. For those toes used the Fillet Feature
  command.

• Tying together mainlines, ramps, bike paths,
  gores, local roads, structures, and walls into
  one dtm.
• Used the Copy Portion of Surface command and
  copies the source surface (surface to be added)
  into the destination surface (combination of all
  surfaces) to combine all the surfaces.
• Trimmed overlapping features using the Partial
  Delete and Delete Duplicate Features command.
  Note fillet returns before adding to combined
  surface.

• Creating the variable slope and width depressed
  median.
• Created a dummy south bound surface with all
  the varying median slopes. The side slopes were
  developed several hundred feet wide so the north
  bound surface would interface into it developing
  a feature in the correct location with the
  elevations.
• Using the Import Geometry from Graphics command
  made the feature into an alignment and had side
  slopes of both north and south bound tie into it
  creating the depressed median of varying width
  and side slopes.
