The Ontario Line is a project for a new automatic subway line, about 13 km long, to serve densely populated areas, as part of an ambitious program to modernize and electrify public transport.

Our mission

As part of this project, Ingerop was called upon by the OTG Ontario Transit Group (FERROVIAL -JANIN – VINCI) during the design-build tender phase to provide a critical review and expert opinion on the electromagnetic studies, including tunnel ventilation, HVAC, electrical power, as well as the interface with the Rolling Stock, Systems, Operations and Maintenance (MRSEM) package.

In addition, Ingerop was retained by Asltom Canada to prepare their bid (with John Laing and FCC) for the catenary component. The mission included :

• setting up a design reference framework, taking into account local regulations and Alstom’s scope of supply
• managing the catenary studies carried out by Alstom’s back-office teams in StOuen
• costing of the project

Abidjan Metro Line 1 is a surface train 37 km long spreading from North to South and crossing the Abidjan lagoon. The line will serve 20 new stations. 2 intermediate terminus stations will allow to operate the central section of the line with a double frequency.

Specificities

The layout uses a narrow urban corridor twinning with the freight SITARAIL line, which implied numerous retaining walls and overpasses.

The construction has been awarded to a consortium led by Bouygues TP under a PPP scheme.

The assignment consists in providing a layout study, then a Preliminary and a Detailed responding to the requirements of the Ministry of Transportation, and defining a bankable project for a PPP realization.

The program and the studies have been optimized to that purpose. For example, one intermediate step consisted in analyzing 3 various infrastructure scenarios, corresponding to 3 tariff scenarios and thus 3 passenger traffic scenarios.

Assignment

The full layout, civil works and stations were studied :

• Main track layout study, and its impact on SITARAIL infrastructures,
• Earthworks,
• Geotechnical studies,
• Hydraulic studies,
• Bridges : underpasses, overpasses, footbridges for public crossings and at stations,
• Stations (platforms, buildings, Civil works and systems integration).
