The 2007 DDE is a compilation of electronic files that configure a client computer or network of client computers to conform to CTDOT’s CAD Standards. The Standards allow the Department to progress toward fully digital deliverables, intermediate digital submissions, and electronic bidding of a digitally signed electronic bid package.      

On June 1, 2007, the Department issued new enterprise wide CAD Standards.  See attached memorandum “Contract Plan Standards” (pdf 912 kb).  

Policy No. F&A-24 “Computer Aided Design, Survey and Roadway Design Software File Formats” (pdf 25.4 kb), dated March 5, 2007, has been reissued.  The policy mandates design software standards. 

The 2007 DDE customizes the user’s off-the-shelf software installation to meet these standards.  This customization is done without affecting any previous configurations the user might have for other clients.  

The methods shown on this site are constantly evolving and are developed for productivity and project data confluence.  While comments and suggestions are welcomed, we do not have the resources to support Consultant Engineers for technical support of the standard software.  The Department will however support any issues with the DDE. 

At this time, there will be no change in project deliverables unless requested in writing by the Department.
