The Project include a Preliminary/Definitive Design of 320 km of Landbridge railway line, which connects Jeddah (Red sea) to Al Jubail (Persian Gulf), in Saudi Arabia. Erregi was involved to develop the section between Riyadh and Jubail (Km 920+00- 1240+00).
The infrastructural project include a Plan/Profile design of double track railway, mostly on viaducts, to avoid siltation, hydraulic study to define culverts and bridges, viaducts structures, seven rail installations, Passing Loop/Wayside maintenances areas, along the main line, with building structures, hydraulic, electrical, power supply, mechanical, fire fighting and plumbing equipment.
The project also Involved structural design of underpasses, overpasses and culverts, road diversions projects and solutions for interferences with main line for stakeholders.
Functional, structural, architectural and facilities design was developed for Main Depot/Marshalling yard, maintenance, storage and workshop of Riyadh with dry port facilities. The design also covered hydraulic study, building structures, hydraulic, electrical, power supply, mechanical and fire fighting and plumbing design for the implantation. Riyadh depot project cover an area of 11 million square meter. The project covered also the Secondary Depot/Marshalling yard and maintenance of Jubail that provides also a secondary dry port design, comprehensive of: hydraulic study, building structures, hydraulic, electrical, power supply, mechanical and fire fighting and plumbing design.
