Algeria’s National Agency for the Engineering and Monitoring of the Achievement of Railway Investments (Anesrif) has invited contractors and engineering consultants to bid by January for multiple rail contracts.

The tenders are for:

• Dualisation of the 53-kilometre north segment of the Annaba-Bouchegouf mining line; alignment; and completion of electrification works, signalling and telecommunications systems
• Dualisation of the rail line along the central segment of the mining line, including alignment and extension of the line by 76km from Souk Ahras to Oued Keberit
• Electrification, signalling and telecom works, including the completion of power supplies along the south section of the 175km mining line which extends from Oued Keberit to Jebel Onk
• Project management consultancy for the Annaba-Djebel Onk mining line
• Engineering consultancy to assist Anesrif in the dualisation of the Annaba-Djebel Onk mining line

Anesrif tendered these five contracts in mid-November and indicated potential bidders have 60 days to prepare their bids.

Works for the Annaba-Bouchegouf line dualisation include site preparation; civil engineering works including rail bridges, road bridges, overpasses and tunnels; building construction works and the supply of tracks and tracks laying material.

The electrification, signalling and telecommunication works for the Annaba-Bouchegouf line entails the supply and installation of signalling systems and telecom equipment, catenary and the construction of sub-stations.

The contract for dualisation of the central segment of the mining line and the 76km extension from Souk Ahras to Oued Keberit include site preparation; civil engineering; building construction; earth and remediation works; and supply of tracks and tracks laying material.

The project management consultancy contract for Annaba-Djebel Onk mining line includes approval of construction surveys; works control monitoring; submission of settlement approvals; validation of commissioning tests and technical support.

The engineering consultancy contract for the Annaba-Djebel Onk dualisation entails assisting Anesrif with the signaling and telecoms project management; engineering and works design analysis; and in transferring the project to the operator.

MEED understands Anesrif earlier tendered a package similar to the last two.

The package tendered in July covers the dualisation, signaling and electrification of the existing 388km railway line linking Annaba and Djebel Onk, and the study of a new 200km line that extends the line from Djebel Onk to El-Oued.

The selected consultancy firm will project manage the development of signalling, telecoms and power supply systems designed to cover 230km of rail network, 31 stations, as well as the renewal of tracks within a specific section of the railway.

The road and ballast renewal work on the existing line is under way and has so far covered 320 kilometres of the network.
