The City of Rio de Janeiro launched a major transformation of its waterfront through the creation of the Porto Maravilha Redevelopment Authority. Key to the redevelopment of the waterfront was the demolishing of the elevated highway running through the area. The Perimetral was brought down, while at the same time two new road tunnels were built. The Rio 450 Tunnel and the Prefeito Marcello Alencar tunnels form one tunnel system and are operated by Concessionária Porto Novo. The redevelopment included the building of the new Calatrava designed Museum of Tomorrow, opened as part of the cities 450 years celebrations.
Together with Amberg Engineering of Switzerland, Enprodes worked on the development of the tunnel safety case which included developing the appropriate tunnel safety documentation. Amberg Engineering provided a detailed ventilation design and the Quantitative Risk Analysis (QRA). Together with Dr Marco Bettelini, Han Admiraal trained the operational staff for the new tasks they were facing. The project had its complications as both tunnels formed one system but were opened on different dates. The tunnel operation also needed to be merged with the existing topside operations of Porto Novo.
Delivered products included the Tunnel Safety Plan, Tunnel Safety Management Plan and the Emergency Response Plan for both tunnels and for the intermediate phase when only the Rio 450 Tunnel was in operation. The Tunnel Operators and Tunnel Patrol Officers were also trained by Enprodes.
