Roadway Design. MISCELLANEOUS (ROADWAY) The Engineer shall provide the following services:
Roadway Design. If requested by the State, the Engineer shall use Bentley’s OpenRoads 3D Design technology in the design and preparation of the roadway plan sheets. The Engineer shall provide roadway plan and profile drawings using CADD standards as required by the State. The drawings must consist of a planimetric file of existing features and files of the proposed improvements. The roadway base map must contain line work that depicts existing surface features obtained from the schematic drawing. Existing major subsurface and surface utilities must be shown if requested by the State. Existing and proposed right-of-way lines must be shown. Plan and Profile must be shown on separate or same sheets (this depends upon width of pavement) for main lanes, frontage roads, and direct connectors. The plan view must contain the following design elements:

Roadway Design. A. Design Surveys and Construction Surveys Design Surveys and Construction Surveys include performance of surveys associated with the gathering of survey data for topography, cross-sections, and other related work necessary to design a project or to layout and stake projects for construction.
Roadway Design. ROADWAY DESIGN CONTROLS The Engineer shall inform the State of changes made from previous initial meetings regarding each exception, waiver, and variance that may affect the design. The Engineer shall cease all work under this task until the exceptions, waivers, and variances have been resolved between the Engineer and the State unless otherwise directed by the State to proceed. The Engineer shall identify, prepare exhibits, and complete all necessary forms for Design Exceptions and Waivers within project limits prior to the 30% Submittal. These exceptions shall be provided to the State for coordination and processing of approvals.
Roadway Design. Traffic Management Systems (Permanent) The Engineer shall design and provide details as a part of the State’s Intelligent Transportation System to be managed from the Combined Transportation, Emergency and Communications Center (CTECC). The design must include elements such as lane-use control signals, variable message signs, closed-circuit Television (TV) cameras, and loop or other vehicle detection devices. The Engineer shall prepare the design and details including conduit and cable, support structures, control equipment, etc. necessary to implement the system. Design specifications shall be defined in the work authorization. The Engineer shall also coordinate with the State Computerized Transportation Management Systems (CTMS) Section should the State have a computerized traffic management system under construction or in place and operating within the project limits.

Roadway Design. MISCELLANEOUS (ROADWAY) The Engineer shall provide the following services: DocuSign Envelope ID: FA09ABAD-94E6-4678-A208-A80E623CD52C
Roadway Design. The Engineer shall prepare roadway plans, profiles and typical sections for the proposed improvements as requested by the State. Prior to the 30% submittal the Engineer shall schedule a workshop to review profiles and cross-sections with the State. The profile and cross sections shall depict the 2, 5, 10, 25, 50, 100 and 500 year (if available) water surface elevations. The drawings must provide an overall view of the roadway and existing ground elevations with DocuSign Envelope ID: F707DECA-9FA0-4A6C-8013-4547938899C1 respect to the various storm design frequencies for the length of the project. This must enable the State to determine the most feasible proposed roadway profile. The State approval of the proposed profiles and cross sections must be procured before the Engineer continues with the subsequent submittals. The roadway plans must be complete and organized in accordance with the latest edition of the State’s PS&E Preparation Manual. FUNCTION CODE 160(161) - ROADWAY DESIGN:
Roadway Design. A. FIELD SURVEYING AND PHOTOGRAMMETRY The Engineer shall provide the following surveying services:
Roadway Design. The Engineer shall provide roadway plan and profile drawings using Computer- Aided Design and Drafting (CADD) standards as required by the State. The plan view shall contain the following design elements: Calculated roadway centerlines for mainlanes, ramps, cross streets and frontage roads, as applicable. Horizontal control points shall be shown. The alignments shall be calculated using GEOPAK. Pavement edges for all improvements (mainlanes, ramps, cross streets, driveways and frontage roads, if applicable). Lane and pavement width dimensions. The geometrics of ramps, auxiliary lanes. Proposed structure locations, lengths and widths. Direction of traffic flow on all roadways. Control of access line, & ROW lines and easements. Begin/end super elevation transitions and cross slope changes. Limits of rip rap, block sod, and seeding. Existing utilities and structures. Benchmark information. Radial call outs, curb location, Concrete Traffic Barrier (CTB), guard fence, crash safety items and American with Disabilities Act Accessibility Guidelines (ADAAG) compliance items. Removal items. The profile view shall contain the following design elements: Calculated profile grade for proposed mainlanes, ramps, cross streets and frontage roads, if applicable. Vertical curve data, including "K" values shall be shown. Existing and proposed profiles along the proposed centerline of the mainlanes, the outside shoulder line of ramps, and the outside gutter line of the designated frontage roads. Water surface elevations at major stream crossing for 2, 5, 10, 25, 50, and 100-year storms. Calculated clearances, taking into account the appropriate super elevation rate. The location of interchanges, mainlanes, grade separations and ramps (shall include cross sections of any proposed or existing roadway, structure, or utility crossing).
