CaroubierWorkshop and Depot: Algeria
Caroubier_Workshop_ and_Depot

The Yapı Merkezi-InfrarailSpA consortium was awarded the turnkey Caroubier Workshop and Parking Area contract by the Algerian National Railway Operator SNTF (SociétéNationale des Transports Ferroviaires). The goal was to replace the existing freight train workshop in the Algerian capital and build a new maintenance and depot area for the fleet of 64 new suburban trains.

Yapı Merkezi acted as the leader of the consortium in partnership with the Algerian company InfrarailSpA, a subsidiary of the SNTF specialised in railway construction.

The project was completed in April 2011, within 27 months.

The scope of the project consisted of dismantling 13km (eight miles) of existing track, laying a total of 10km (6.2 miles) of new track, infrastructure works and construction of the new workshop and other technical and administrative buildings (a 28 500m2 closed area). This included electromechanical installations, the supply and installation of workshop equipment, electrification and catenary systems, the construction of access roads and parking areas and landscaping of the entire complex.

BirTouta – ZeraldaDouble-track Railway Line: Algeria

This project is located 25km (15.5 miles) south-west of the Algerian capital, Algiers, and consists of a new 20km (12.4-mile) double-track railway line with a 140km/h (87mph) design speed. Once completed, it will serve as the railway link between the city centre and the Zeralda district.

Along the alignment there are four railway viaducts, five railway bridges, six highway bridges, one 343m cut-and-cover tunnel, one 261m cut-and-cover structure, 540m of retaining walls and five new stations. The region’s hilly geography requires approximately 10 million m3 of earthworks and 27 500m2 of new heavy construction structures like bridges and viaducts.

Electrification, signaling (ERTMS Level 1), telecommunications and commissioning are also within the scope of the turnkey contract.

The projectis beingundertakenby a consortiumconsisting of Yapı Merkezi (consortiumleaderwith 87% share) and InfrarailSpA (13% contract share). The project is expected to be completed in July 2015.

Casablanca Tramway: Morocco

The Casa Tramway consists of 31km (19.3 miles)

of double-track tramline with 48 stops. The capacity of the transportation system is about 250 000 passengers/day. It’s the biggest urban rail system in North Africa, the second tramway in Morocco after Rabat and the first tramline in Casablanca.

After its inauguration in December 2012 the tramway has contributed massively to address the lack of urban mass transport in Casablanca, and has also generated an equilibrium between the different quarters of the city by opening up the suburan areas and bringing them closer to the city centre.

This project is also leading Casablanca into a new phase of urban regeneration through the completed works, which include the rehabilitation of the existing pavements with new borders, renewal of the city’s underground sewer network, installation of a new public lighting infrastructure and modern street furniture, the opening of five interchange stations to integrate with the other public transport modes and the planting of 4000 palms and shade trees.

Within the remit of this project, Yapı Merkezi has completed 21km (13 miles) of double-track tramway, a 61 000m2 depot area, 6.5km (four miles) of single-line tramway at the depot and 12 stops.

As the main contractor, Yapı Merkezi carried out the mobilisation works and successfully completed its phase of the works in less than two years – well ahead of the expected completion time. The project was completed within 26 months in total.

The Casa Tramway project was “Highly Commended” by the judges in the Worldwide Project of the Year category at the 2012 Light Rail Awards – held in association with Tramways & Urban Transit.

Sidi Bel Abbès Tramway: Algeria

This light rail project in Sidi Bel Abbès is a tramway with a core portion in the northern part of the city (Inter-station SidiDjilali / Benhamouda).

It will connect the city from the new August 20 stop on the southern ring road to the Cascade Station located in the east, along the western ring road that encircles the city. This route will allow the service to serve major points of interest and significant passenger generators such as the Institute of Medical Sciences, the hospital, the southern bus station, public gardens, the city’s core downtown area, SidiYacine, Maternity, the North Bus Station, the future railway station and the university campus.

In addition to the tramline, four park-and-ride sites and four interchange stations are planned. These intermodal hubs are located at the South Bus Station, the new railway station, the North Bus Station and Bus Station East. The park-and-ride sites are located at the South Bus Station, Maternity, Bus Station and North Station Road East.

There will also be a Maintenance Centre (CDM) and a Centralised Command Post (PCC) that will be located in the workshop.

The proposed tram system will feature low-floor trams with a length between 40m and 45m with a power supply of overhead catenary lines.

The entire line, including infrastructure and switche, is 17.9km (approximately 11miles). A total of 26 stops will be served by the tramline with an average spacing 157between stops of 700 m. The expected completion date is October 2016.

Sétif Tramway: Algeria

Another project for Yapı Merkezi in Algeria is the Sétif First Line Tramway Project in the city of Sétif, located 220km (approximately 170miles) south-east of the capital city. Construction of the project has been awarded to a consortium of Yapı Merkezi and Alstom Transport.

The scheme consists of two sections: the first will link the eastern neighborhoods and university with El Bez; the second will connect the crossroads of the Wilaya to Nova Bus Station and then on to Ain Trick.

The lengths of the lines, without taking into account the terminal connections and the depot total 22.2km (13.8 miles); 27 stops will be created for the first section and ten stops for the second section.

There are a total of 15 substations on the line, supplying a line voltage of 750V dc. There are two depots, one on a plot of eight hectares and the other on a plot of two hectares. There are four interchange stations and six park-and-ride sites along the line. The duration for this tramway project is 44 months.

Through its network of specialised companies, Yapı Merkezi has completed numerous successful national and international projects within the fields of transportation, rail systems, tunnels, bridges, viaducts, industrial and general service buildings, water collection and supply systems, restoration, strengthening and repair works, and mass housing and city planning.

Yapı Merkezi aims to continue its universal contributions to the civil construction sector by assuming and successfully executing important duties in construction projects both in Turkey and around the world.
