Geometric Design Schematics. Based on the review of the corridor alternatives analysis, Technical Work Group, and Public Meetings the Engineer shall prepare the geometric design schematic of the preferred alternative (i.e., design DocuSign Envelope ID: B4E47CBB-54AA-4467-B86B-B1C47B94F45E schematic) on continuous rolls (maximum 2 ft. wide and 10 ft. long) in plan and profile to a scale of 1”=200’ horizontal and 1”=20’ vertical. This task must be performed by the Engineer through GEOPAK V8i SS3 software and OpenRoads Technology to produce 3D design files. All schematic design must be in conformance with the Fort Worth District’s Ramp Geometric Standards where practical, but at a minimum to the requirements of the Roadway Design Manual. The intent of this criterion is to create general uniformity in ramp configurations. Where deviation from this criterion is requested, the consultant shall submit the deviation request with applicable documentation for review and approval by the TxDOT PM.
