Hydro

  Odebrecht is building the San Francisco hydro scheme, located downstream of the existing Agoyan power plant, on the left bank of the Pastaza river, on the border between Tungurahua and Pastaza provinces in central Ecuador. The project will make use of water discharged from the Agoyan power plant and diverted from the Verde river. Interconnection is made through a 60 m-long tunnel linking to an underground interconnecting chamber, from which a 11.3 km-long 7 m-diameter headrace tunnel will connect to a surge tank. Before reaching the surge tank, the penstock tunnel divides in two vertical stretches, with the upper concrete-lined section connecting with the surge tank and the lower steel-lined stretch connecting with the two generators in the 230 MW underground power house. The water will be discharged into the Pastaza river through a low pressure tunnel. Conelec, the national electricity authority, awarded the contract in March 2000 to Hidropastaza, a joint company controlled by Hidro Agoyan (80%) and Odebrecht (20%). The concession company will build the project under a 30-year BOT concession agreement for USD306 million. Construction to take five years. As of March, 2005 the underground powerhouse has been excavated. The tunnel will be excavated by a 7 m-diameter Wirth double shield TBM, which will be operated by SELI under the supervision of Odebrecht.

The consortium, comprising the French Colas Rail (leader, 35%), Orascom Construction (35%) and Hitachi Rail (30%), has signed a EUR850 million contract with the Egyptian National Authority for Tunnels (NAT) to renovate line 1 of the Cairo underground system. The contract involves the modernization of the systems (signals - communications - central control - E&M works - electrical power - overhead network - track works).

This was the first metro line in Africa and the Middle East,  it started operating in 1987 about 40 years ago and is considered the backbone of the Greater Cairo Metro network.   Funding for this project will be provided by the European Bank for Reconstruction and Development (EBRD), the European Investment Bank (EIB), and L’Agence française de développement (AFD).  The development works for this line will ensure the quality and continuity of the service it provides, to preserve assets, and to reduce maintenance and operating costs. The metro is important as alleviates traffic pressure on Cairo's streets  reducing pollution and travel time.  

The project is expected to start in October 2024 and will run for 64 months, with works being executed without any interruption to commercial operation.  The line systems modernization works will be implemented in conjunction with the development of the fleet of moving units, as (23) trains are currently being rehabilitated, in addition to the manufacture and supply of (55) new air-conditioned trains for the line to accommodate the steady increase in the number of passengers after the completion of the metro network, as the line's capacity reaches 1.5 million passengers/day.
