Réseaux de télécommunications

 

Client
OLRT (Ottawa Light Rail Transit)

Mandate
Analysis of conflicts between underground telecommunications infrastructures and networks of six companies and the construction of a 2.5km tunnel and three stations for the new light rail train in Ottawa.

Working closely with the City of Ottawa, Rideau Transit Group will design and build the Confederation Line during the next five years and maintain the line until 2038.

With a tunnel of 2.5 km from the city center, Ottawa light rail system will be faster than ever. The Confederation line is a transport system worthy of one of the leading capitals of the world. Overall, thirteen stations on a route of 12.5 km, of which 10 km are located above ground and 2.5 km will be located underground. Three of the thirteen stations planned will be located in the new tunnel located downtown.

The construction of this tunnel and three stations generates many potential conflicts with the various underground infrastructures for public utilities services that are present on this section and includes ventilation towers and tunnel entrances and exits.

Infrastructel was mandated to conduct a detailed analysis to determine how to eliminate conflicts between public services and infrastructure of three subway stations to be built in this important project. The activities carried out under this project should take into account all infrastructures and telecommunications networks of the following players: Bell Canada, Bell 360, Rogers, Videotron, Cogeco and Allstream.

Team Infrastructel conducted the analysis of all the plans to determine all potential conflicts with utilities companies, met each of the stakeholders whose infrastructures have been identified as being in conflict with the construction of the three stations, identified solutions for each section of the conflicting network, determined the cost estimates for all work to be done (temporary, permanent and protection), performed detailed engineering and provided technical assistance in the realization of construction work

Ce projet est actuellement à la phase de construction. Le client a également donné à Infrastructel la responsabilité de surveiller tous les travaux liés aux services d’utilités publiques.
