This is an Electronic Engineering Data (EED) File Manifest submitted to the Connecticut Department of Transportation (CTDOT) for Project Number 0083-0270, the Milford Connector Bridge 06770 project. The manifest was submitted on May 29, 2026, by Amanda Czerwiec of Clough Harbor and Associates. The deliverables consist of multiple CAD files organized by category, including bridge design models (Bridge No. 06770), highway alignment files for Milford Parkway, East Access Road, and West Access Road, highway layout and master model files, ground survey files and terrain models for District 3, and traffic models. All files have been reviewed and certified as ready for EED submission in accordance with CTDOT guidelines and utilize NAD 1983/NAVD 1988 survey datums.

The manifest includes a comprehensive Electronic Engineering Data Quality Control Checklist that establishes CTDOT's technical requirements for CAD file submissions. All deliverables must be compatible with CTDOT's Digital Design Environment (DDE), utilize real-world modified state plane coordinates, and be geospatially correct. Specific requirements address 2D and 3D DGN files, coordinate geometry alignments, structure and bridge models, traffic signal and sign equipment, and terrain models with 3D meshes. The quality control checklist mandates that files be free of construction lines, cross-sections, and annotation; contain only final design information with preliminary and alternate data removed; and meet stringent surface smoothness standards for automated machine control guidance purposes, including minimum offset specifications for vertical surfaces of 1/12 to 1/8 inch.
