Chapter 2 - Data Requirements
2.1 Level of Detail Requirements
The Reference Information Documents (RID) process will require the inclusion of proposed 3D models for all projects as a general rule. Please refer to the Project Data Requirements Table.png document to determine the categories that are required for each project type (Project Description). The table is intended to capture the majority of the projects listed under each project description. At the discretion of the MDOT Project Manager some of the categories or RID files may be excluded based on the project parameters. For exceptions to all RID categories MDOT Project Managers can designated the RID category or File as 'N/A' on the RID Review Checklist.xlsm with justification provided in the Preliminary Comments column. MDOT RID Support will then review the exceptions with the Preliminary Submittal.
To help clarify the intent of when a 3D Model is required the following project types are generally excluded from this requirement:
- Log projects
- Standalone bridge projects
- Mill and fill projects
- Pavement patching and repair projects
- Crush and shape projects
- Projects without survey
Unless:
- There is wedging, widening, or earthwork for more than 1,000’
- The road elevation changes more than 3â€
- The cross slope changes for more than 1,000’
- The superelevation or transition changes
- The improvements re-grade more than a total of 1,000’ of ditch
- The improvements impact ROW
- The horizontal or vertical alignments change
The above lists are intended to be a starting point to help clarify the 3D Model requirements, and to convey the thought processes used to determine 3D Model requirements. We encourage design teams to provide input as they work through unique and challenging situations.
2.2 Software Requirements
2.2.1 MDOT Workspace
For consistency and uniformity MDOT provides a CAD workspace for free download at the following location:
http://www.michigan.gov/mdot/0,4616,7-151-9625_21540_36037-259870--,00.html
The current workspace is MDOT_01 and the MDOT_02 workspace is currently optional. It is required that the MDOT_01 or the MDOT_02 workspace be utilized for all design work. Updates are no longer being made to the MDOT_01 workspace. Projects currently underway in the MDOT_01 workspace should remain in this workspace.
2.2.2 MDOT Road Design Software Requirements
In order to provide consistent, uniform deliverables MDOT designers must utilize the current MDOT accepted version of Bentley Power GEOPAK (or MicroStation plus GEOPAK equivalent package). Please note that the following combination of software versions is required:
Power GEOPAK | |
---|---|
Program | Version |
Power GEOPAK V8i (SS3) | 08.11.09.722 |
Power GEOPAK V8i (SS2) | 08.11.07.566 |
GEOPAK Civil Engineering Suite | |
---|---|
Program | Version |
MicroStation V8i (SS3) | 08.11.09.608 |
GEOPAK Civil Engineering Suite V8i (SS3) | 08.11.09.723 |
GEOPAK Civil Engineering Suite V8i (SS2) | 08.11.07.615* |
* Note that the version of MicroStation SS3 listed above is fully backward compatible with Civil Engineering Suite SS2 and this is the only version of MicroStation SS3 that supports both versions of Civil Engineering Suite listed above.
Please be aware that the MDOT_02 Workspace is not currently set up for use with MicroStation/GEOPAK Civil Engineering Suite and knowledge of workspace configuration is therefore required to modify the workspace as needed. |
This software must be used in conjunction with MDOT’s current Workspace. Refer to Section 2.2.1 MDOT Workspace.

2.3 Digital File Formats
Electronic Data is to be delivered in the following digital file formats:
File Type | MDOT Delivered Format |
---|---|
CAD Graphics (2D & 3D) | .dgn (MicroStation / Power GEOPAK design file) |
Survey Control Coordinate Files | ASCII .txt |
Alignments (Horizontal and Vertical) | .xml |
Existing & Proposed Surface Data | .xml |
Cross Section Data | .dgn and .pdf |
Reports | |
Photographs | .jpeg |
