| Abstract: |
The project of the New Coastal Road (NRL) with a length of 12,5 km includes a 5,4 km viaduct divided in 7 viaducts of 770 m long entirely precast near the “Le Port” commercial harbor and completely assembled at sea. The project had to integrate environmental dispositions to protect the marine fauna. Set up at sea, geological maps and geotechnical surveys were needed to provide precise conditions of landing of the footing pedestal of piers. Specific temporary equipment were needed following the construction sequences elaborated by the technical studies. To precast the total viaduct, foundation, piers and segments of the decks with their unusual width of 28m, needed a significant site installation in order to meet the deadlines set in the schedule. This paper deals with the organization set up by the contractors’s joint venture to manage the issues of the project during the studies stage before the construction works. |
