Geometric Design. The CONSULTANT will perform geometric design using the established Project design controls and criteria. The CONSULTANT will also use Project traffic data and results of traffic analysis to design appropriate roadway elements. The CONSULTANT will establish both preliminary vertical profile and horizontal alignments of the mainline. The design of Project alternatives must consider environmental constraints, physical constraints, Context Sensitive Solutions, Complete Streets, and any additional information, as required. See Part 2, Chapter 3 of the PD&E Manual for more engineering and design considerations. For each alternative evaluated in detail, the CONSULTANT shall prepare sketches of plan, profile, and typical sections as appropriate to show existing features, proposed geometry, and location of any environmental and geometric design constraints.
Geometric Design. The report should discuss design concerns regarding geometric requirements for the proposed work. Standard design values (as listed in AS 150/5300-13) based on the design aircraft shall be identified in this report. Examples of these standards include runway/taxiway dimensions, taxiways fillets, separation requirements and etc.
Geometric Design. The Engineer shall review the schematic provided by the State to confirm their understanding of the project and to verify completeness and accuracy of the information. The Engineer shall refine the horizontal and vertical alignment of the design schematic in English units for main lanes, ramps, xxxxxxxx xxxxx, xxxxx xxxxxxx, including grade separation structures. The Engineer shall determine vertical clearances at grade separations and overpasses, taking into account the appropriate percent grade and super-elevation rate. Minor modifications in the alignment must be considered to provide optimal design. Modifications must be coordinated with the State and adjacent Engineers. The State must approve the refined schematic prior to the Engineer proceeding to the 30% milestone submittal, and prior to starting on the bridge layouts. CADD files and the 3D model shall be created using Bentley’s OpenRoads GEOPAK (SS4) software.
Geometric Design. Xxxxxx will provide geometric design in accordance with FAA AC 150/5300-13 (latest edition) or other local standards. The following design criteria will be used for airfield design: • Airplane Design Group (ADG) – II • Taxilane Design Group (TDG) – II

Geometric Design. The geometric design criteria to be adopted for road design shall be: ● Design speed: - 30km/hr min (lower speeds may be selected depending on available right of way, pedestrian presence, adjacent development, and other area controls. All design elements should encourage speeds generally not exceeding 50 km/hr. ● Sight distance: - Stopping sight distance should range from 30 to 60 m depending on the design speed. Design for passing sight distance is not applicable. ● Grades: - The minimum longitudinal grade for roads should not be less than 0.3%. Max's grades should not exceed 5.0%. ● Cross fall: - As a guide, the normal cross fall (slope of the surface of the carriageway measured normal to the centerline) should not exceed 2.0%. In wide parking areas and queuing areas, the minimum cross slope shall be 0.5%. ● Super elevation - Curves should be designed for a maximum super elevation rate of 2.0%. A rate of 4.0% may be used when it is absolutely necessary. - Width of roadway: The carriageway shall have sufficient width to meet the needs of the future vehicle and pedestrian traffic. The minimum lane width shall be 3.6m for cars and buses, and 4.0m for trucks. Where curbstone is used at the edges of the carriageway, then the curb should be offset by 0.3m on the left edge and 0.6m on the right edge where no parallel parking is provided. - The road reserve will be designed to take account of the location of existing and future services, including drainage, overhead and underground utility services, and road furniture including signs and lighting. ● Intersection design: - The vehicle turning path design shall be specific to each intersection. - The design shall cater to the future vehicle configuration. As a guide, the AASHTO WB- 19 shall be considered as a design vehicle.
