“Construction of Light Railway Line in Granada between Maracena and Villarejo”, for the Regional Government of Andalusia,  Andalusian Railways Company (Spain).

 Total project value: 45509919.00 €

Double track system with unballasted tracks

 Length: 3,5 km

The Project includes the necessary actions to execute double track light railway type infrastructure and superstructure, mainly across the municipality of Granada.

Works include earthworks, utilities diversion (gas, low voltage, sewerage, water, etc.), platform preparation, slab track, station paving and utilities installation. Foundation for catenary parts and cable installation along the track

Several concrete structures and crossed Under main roads and other railway lines. Most significant structure under existing motorway using “cut and cover” methodology with cast-in-place concrete piles and using the pushing system for under railway crossings.

Other Works include urban infrastructures around the tracks and building of stations and catenary posts.

 The consortium, known as Al Shoula Group, is made up of twelve Spanish companies: Imathia Construcción, Adif, Renfe, Talgo, Indra, Dimetronic, Cobra, Inabensa, Copasa, OHL, Consultrans, Ineco and two Saudi Arabian companies, Al Shoula and Al Rosan. This award is further demonstration that Spanish engineering is at the highest level in the world and that the Spanish high speed model is an example of excellence exportable to other countries. 

The project involves the construction of the high speed railway line between the cities of Mecca and Medina with a length of 450 km of double track for speeds of up to 320 km/hour. The line will have stations in Mecca, Jeddah, the King Abdullah Economic City (KAEC), the King Abdulaziz international airport and the city of Medina.

Imathia Construccion is a member of the Civil Works Subgroup, responsible for the construction of the 450 km of track (both in ballast and slab track and the construction of the workbases. Four work bases will be built in differnt points of the route for rail asembly and other track laying related activities.  Three of those bases will be left for maintenance  once operation of the line starts.

The civil works subgroup will also have to implement an effective sand mitigtion approach to keep the sand out the track.

After the construction period Imathia Construccion and Copasa will have to carry out the maintenace of infrastructure of the line for a period of 12 years.

“Tarragona-Barcelona-France Line. Removal of the level crossing of the Km.157/530 and 157/630 and construction of two lower pedestrian crossing at Km. 157/495 and 157/630 and  lower vehicles crossing at  Pk. 157/921. Sant Celoni (Barcelona)”, for the Spanish Ministry of Public Works, Railways General Management Department.

Double track system with ballasted tracks, Length: 450 m, Short and long distance railway traffic

Construction of 3 structures under double track railway line, one for road traffic and the other two for pedestrians. The main caisson was cast-in-place and pushed under the existing railway, the pedestrian caissons built using two prefabricated caissons and pushed and the tracks with slurry walls coming out under crossing.

Other works include access roads, urban infrastructures around the level crossing, lighting infrastructures and improvements in the local drainage.

More detailed track works may include:

Updating of sleepers

Installation and retrieval of temporary beams  and trac supports

Excavation under tracks

Instalation of ballast

Installation and retrieval of track supports

First Levelling

Alignment and profiling os track

Second Levelling

Dynamic stabilization

The section Nudo de Bobadilla (Antequera), Phase II, has a length of 6.15 km and runs through the town of Antequera, in Málaga province. The proposed works involve the implementation of the platform of the High Speed Line Antequera-Granada. In this section there are junctions that allow the connection of Málaga and Granada at high speed. The project includes the necessary actions for the implementation of infrastructure works such as earthworks, drainage, structures, replacement of services and easements, and construction of cross connections to ensure patency of the line road. The new layout has been designed for high speed double track standard gauge and for exclusive passengers traffic. It´s worth mentioning, as unique elements, the 74m. pergola on the Córdoba-Málaga High Speed Line and the 258 m. Viaduct over the Arroyo de Las Lomas, box section post-tensioned panel executed in situ. The Bobadilla Node is the key point of connection between the future Andalusian cross passage at high speed, to which the High Speed Line Antequera-Granada belongs, and the High Speed Line Madrid-Córdoba-Málaga. It also represents an essential core at the joint of the rail network in Andalusia to the rest of the peninsula.
