Road Construction

ROAD CONSTRUCTION​

There are several phases in the road design process: the preliminary design phase and the detail design phase. During the preliminary design phase, possible route options are compared and selected, then the alignment and structure are designed. The detail design phase, drawing for construction, and materiality calculations are conducted. Along with road designs, we plan and design various road structures, such as interchanges, retaining walls, and excavation slopes. 

Preliminary/Detailed Auxiliary Road Structure Designs

To ensure stable road structures, Geranium Limited coordinate designs for retaining walls and excavation slopes with the main road designs.

Preliminary Road Designs

We provide optimal route and road structure designs, which take into consideration both the current land utilization and topography of the target area. To ensure stable road structures, we coordinate designs for retaining walls and excavation slopes with the main road designs.

Road/Intersection Preliminary Engineering Designs

We take the rough route generated in the preliminary design and based on a highly detailed topographic map, we provide concrete plans for the road alignment, intersection shapes, and road structures.

Detailed Road Designs

In our detailed road designs, we cover the detailed framework necessary for road construction, which includes drainage channels, guardrails, and medians, retaining walls, pavement, lane markers, etc. We provide optimal route and road structure designs, which take into consideration both the current land utilization and topography of the target area.

 

Detailed Interchange Designs

For our detailed interchange designs, we first compare options based on traffic volume, service levels, and topography, and then select the most suitable choice.

Detailed Intersection Designs

Depending on traffic volume, we carry out comparative reviews on multi-level types and then provide designs for the traffic lane configuration, lane markers, and safety facilities such as traffic signs.
