The Engineer shall comply with all relevant sections of the latest edition of the TxDOT Bridge Design Manual - LRFD, TxDOT Bridge Project Development Manual, TxDOT Bridge Detailing Guide, and AASHTO LRFD Bridge Design Specifications, and respective checklists. Each bridge layout sheet must include bridge typical sections, structural dimensions, abutment and bent locations, and superstructure and substructure types. The Engineer shall locate and plot all soil borings and utilities, show proposed retaining walls, and, for staged construction, indicate limits of existing bridge for removal and reconstruction. 4) The Engineer shall confirm approval from the County prior to proceeding with final bridge design. The Engineer will make necessary revisions to the layout to reflect the progress of the final design. The Engineer shall comply with all relevant sections of the latest edition of the State’s Bridge Design Manual-LRFD, Bridge Project Development Manual, Bridge Railing Manual, Bridge Design Guide, Bridge Detailing Guide, and AASHTO LRFD Bridge Design Specifications. Each bridge layout sheet must include bridge typical sections, structural dimensions, abutment and bent locations, superstructure and substructure types, and any pertinent information from the Bridge Detailing Guide layout checklists. The Engineer shall locate using the County provided information and plot all soil borings and utilities, show proposed retaining walls, and, for staged construction, indicate limits of existing bridge for removal and reconstruction. Bridge layout must include all information that is specified in the Bridge Detailing Guide. 5) For highway caps and demolition: Engineer shall develop preliminary bridge layouts to accompany the load rating and retrof...

Bridge Design a) The Engineer shall perform bridge design required for any roadway crossings to the proposed improvements to the existing channels and/or proposed channels of the Project. The design of these bridges shall conform to the Project design criteria required by the Owner (City, County, or State), of the associated b) Prior to performing structural detailing, the Engineer shall provide a bridge layout to the governing entity of the associated bridge structure and/or roadway for approval. Each bridge layout will include the required information set forth by the governing entity.
Bridge Design. 3.3.2.1. 1Bridge Geometrics
Bridge Design. If necessary, design a bridge structure to cross potential wetlands along the proposed ROW alignment will be designed for HL-93 loading or greater. The design will include all supporting calculations for the structure including geometry, structural design, layout sheets and details. The bridge will be 4 lanes (two lane in each direction). We will also provide two (2) borings 80’ in depth for the bridge design. The fee for this item is included in the base geotechnical fee.
