What is the ProjectWise DDE?

The ProjectWise DDE (Digital Design Environment) is a compilation of electronic files that reside in the CTDOT's ProjectWise Datasource. These files are configured  be used as a managed ProjectWise workspace and to conform to CTDOTís CAD Standards (DDE is configured for Bentley Products). The DDE customizes usersí commercial-off-the-shelf (COTS) CAD software installation without compromising previous configurations or standards that they may have for other clients. These standards allow the Department to continue developing on its existing digital contract plans and specification submission process, and progress toward a fully digital project. In addition, with standardized digital contract plans the Department is also able to implement electronic bidding of digitally signed electronic bid packages.  A full manual for the ProjectWise DDE has not been written but workflows and guides applicable to the ProjectWise DDE are available in the left pane on this page.

CAD Environment Set-Up for Consultant Engineers:

The step by step set-up workflow and zip file Download used with the previous SELECTseries DDE will not be applicable to be used with the ProjectWise DDE. All consultants will be required to access the workspace through ProjectWise.  This will require each consultant to have the ProjectWise Thick Client on their workstation.  CTDOT will not support the use of Bentley Power Products so consultants will need the full installation of MicroStation, OpenRoads etc.. Consultant engineers, municipalities and any other private parties will need to contact their CTDOT consultant liaison to gain access to the projects they will be working on in ProjectWise. 

Who should use the ProjectWise DDE?

Anyone using OpenRoads, OpenBridge or Building Designer will need to use the ProjectWise DDE.  Adhering to this requirement shall be included in the general cost of doing business for the CTDOT and shall not be used to seek additional compensation. Consultants working on existing CTDOT projects may migrate from previous Digital Design Environments to the latest SELECTseries DDE (with no additional compensation).

Has the required project deliverables changed with the SELECTseries DDE?
YES, Please refer to the May XX, 2016 EED (Electronic Engineering Delivery) Directive.  Please also refer to The Digital Project Development (DPD) Manual for the PSE (Plans, Specs. and Estimate ) requirements. The EED will contain High Value Data (HVD) such as: Terrain Models, Alignments, Drainage Databases, and 3D Models in conformance with the ProjectWise DDE.

***Methods shown on this site have been developed for productivity and project data confluence, and are constantly evolving. Comments and suggestions are welcomed, and the Department will support any questions and issues with the DDE; however, we do not have the resources to support Consultant Engineers for CAD technical support outside of direct issues with the DDE. 

What are the benefits for using OpenRoads?

Advantages of using OpenRoads Technology include enhanced conceptual design tools as well as the ability to make design decisions while building dynamic models.  The interactive, dynamic, intelligent modeling of roadway components enables users to create information-rich models.


  • ensure project engineering accuracy with embedded design intent that maintains associations and relationships between civil elements; object information, including how, where, and by what method it was created, is stored with each object to ensure the original intent is retained and honored in the design;
  • facilitate better design decisions with design-time visualization that enables users to view designs at any time, on demand, within the modeling workflow; no translations, software, or special workflow processes are needed;
  • improve design quality via immersive modeling by combining plan, profile, and cross-section workflows with innovative 3D modeling technology; the further addition of parametric design features that allow users to incorporate rules, relationships, and constraints into the modeling workflow provides incomparable modeling capabilities;
  • increase productivity with integrated corridor and site design so that sites can now automatically respond to any modifications to corridor conditions; since all aspects of the design are stored in the model, relationships in the design are automatically recognized by other objects;
  • Accelerate design production with civil cell functionality that helps engineers repurpose common 2D and 3D geometric configurations in design layouts; design, constraint, and relational intelligence are maintained between elements to ensure design standards.

Policies and Memorandums

May XX, 2016
Coming Soon - EED (Electronic Engineering Delivery)

May 1, 2011
Digital Submissions of Final Contracts - Mylar Plans retired.  As of May 1, 2011 the Department will require the submission of Final Design Documents to conform to The Digital Project Development (DPD) Manual.  This will be in effect for projects advertised by the Connecticut Department of Transportation only.

The Department issued new enterprise wide CAD Standards.  See attached memorandum 

"Contract Plan Standards".

March 5, 2007

Policy No. F&A-24 "Computer Aided Design, Survey, and Roadway Design Software File Formats" The policy mandates design software standards.
