Roadway design in Civil 3D

Alignments, profiles, cross sections, grading, and corridor models built as one connected Civil 3D model, so the plan sheets, the quantities, and the staking notes stay consistent as the design changes.

We have carried county and city roadway projects from concept alignment studies through final plans, to ODOT, PBOT, and county standards. The design lives in one model. When the profile moves, the sections, the quantities, and the staking notes move with it, which is what keeps a 90 percent set from contradicting itself.

What you get

  • Horizontal and vertical alignment design

    Plan and profile sheets drafted to your CAD standard, in your sheet layout and your layers.

  • Cross sections

    Typical sections, and specific sections cut wherever the design or a reviewer needs one.

  • Corridor model and grading

    A surface model that shows the low points and where runoff will collect before anyone pours concrete.

  • Intersection layouts and sight distance checks

    Checked in the model, not estimated from the plan view.

  • ADA facilities in the same model

    Curb ramps and sidewalks graded with the street, not drawn on top of it afterward.

  • Concept layouts

    Corridor and roundabout concepts for planning studies and public meetings.

  • Quantities and staking notes

    Taken from the model, so the estimate and the staking match the plans.

Projects

  • Full-depth reclamation, Marion County, 2017. Full horizontal and vertical design of about three miles of county road: typical and project-specific sections, intersection layouts, retaining walls, grading, and sight distance checks.
  • Wintercreek Road Reconstruction, Marion County, 2017 to 2018. 75 percent plans through final signed plans and construction staking notes.
  • Front Ave-Naito Parkway LID Project, Portland Bureau of Transportation, 2017 to 2018. Plan production and PS&E as a subconsultant to Kittelson & Associates.
  • Low impact design road project, City of Portland, 2017. 30 percent paving and erosion control plans.

Standards and software

ODOT and PBOT design standards, county road standards, and PROWAG for every pedestrian facility inside the right-of-way. Autodesk Civil 3D for design, and Bentley MicroStation with InRoads or OpenRoads when the agency's standard calls for it.
