IH35E_3D_MasterComponents.DGN ReadMe File
1.0 Project Description
This project included the preparation of a 30% Plans, Specification, & Estimate for the
reconstruction of IH 35E from North of Eighth Street to North of IH 30, including the IH 30/IH 35E
Interchange (known locally as the Mixmaster Interchange). Interim transitions will be
constructed on each end to tie the proposed improvements to the existing highway. The Engineer
shall prepare plans, details and compute quantities to include grading, paving, drainage, removals,
bridges, retaining walls, traffic control and construction sequencing, signalization, storm water
pollution prevention plans, signing, pavement markings, illumination, and miscellaneous details.
The intent of this file is to serves as a guide for the documentation of all files located utilized in the
process and the development of the 3D Roadway Component file for the project.
2.0 File Management Processes
The 3D Roadway Components file was generated for ease of visualization of the 3D elements for
the entire project. Three main files make up the master file, I35E_MasterComponents.dgn, and
thus contains all the project surfaces. However, MicroStation *.dgn files were further subdivided
for the purpose of design development and control of visualized elements and are referenced into
the master DGN file. The following three reference files outline the design files developed for each
project:
2.1 - I35E_MasterComponents File
The master file is comprised of three reference files. The three files are as follows:
1. Roadway Component File
2. Superstructure Component File
3. Existing Component File
These files can be turned off or on to visualized the separate components individually or if
a certain component of the project needs to be provided to design team independently.
Each of the three referenced files contains multiple Microstation models to reflect each of
the independent roadways and structures (and a master model that encompasses all
models).

2.1.1 – Roadway Component File
The roadway component file contains multiple models that reflect each of the independent
roadways so the designer can easily isolate any particular area of the project. This file
contains all the roadway surfaces including all end conditions, i.e. curb, sidewalks,
barrier/rail, walls and side slopes. It also includes a 16.5-ft vertical clearance envelope that
was utilized to verify clearances. All the roadway surfaces are independent Microstation
models that are contained within this reference file. The following is a table containing all
Microstation Models that make up the 3D Roadway Component File.

independent bridges so the designer can easily isolate any particular bridge. This file
contains all the bridge surfaces including beam type utilized. It also includes a 16.5-ft
vertical clearance envelope that was utilized to verify clearances. All the bridge surfaces are
