Egis, in consortium with the VINCI group, is starting this emblematic project with the objective of securing the drinking water supply for more than 300,000 inhabitants of Nairobi.
Drinking water "H24" for the populations of the outskirts of Nairobi? This is the ambition of the Ruiru II project.
Launched in 2012 by the Athi Water Services Board, the organisation in charge of water management in Nairobi, Ruiru II is a major project aimed at sustainably improving the water supply in the outskirts of Nairobi, i.e. 300,000 inhabitants.
A project involving the construction of large-scale works, including:
More than 1 million m3 of cut and fill will be required to build the dam. The construction operations also involve temporary and permanent access, the opening and rehabilitation of borrow pits and quarries, the temporary diversion of the river through the concrete channel and the creation of cofferdams some 20 metres high upstream and downstream.
Egis, as part of the consortium, is responsible for carrying out the complete design of all the project's structures, from preliminary studies to execution plans.
During the construction phase, Egis will be responsible for the integrated supervision of all works, including the management of the site laboratory, the installation of the dam's instrumentation, and the monitoring of social and environmental aspects.
"This project is a new opportunity for Egis to showcase all of its specialities in geotechnics, civil engineering, hydraulics, water treatment and the environment, and to fully exploit the synergies between our French and local teams". Frédéric Walet, Deputy CEO in charge of operations for the BU Major Structures, Water, Environment, Energy.
The size and number of structures to be built, the complexity of the technical challenges and the very high level of cooperation expected between the various specialities based in several countries led Egis to design the entire project in collaborative, multi-site BIM mode.
"This working method requires a high degree of knowledge of software ranging from 3D models to electronic document management, all linked by a common data environment. The work will be carried out through two collaborative platforms (Project Wise and SGTi4); we are assisted for this project by our best "BIM by Egis" specialists." Arnaud Le Peillet, Project Manager
It's a great adventure that's just beginning....
