- Mejillones 500 kV HV Power Transmission System
- Service & Electrical Works for Chuquicamata Tunnels
- Escondida Water Supply (EWS)
The EPC contract comprises the engineering, procurement and construction for “Infraestructura Energética Mejillones – Cardones” High Voltage Power Transmission System, owned by TEN (Transmisora Eléctrica del Norte) – GDF Suez, developed between Antofagasta and Atacama Regions, with 600 km – extension.
As part of Mina Chuquicamata Subterránea Project (PMCHS), there is the early lining service works for the Main Access Tunnels (TAP) and Main Transportation Tunnels (TTP). Scope considers basic services / utilities installation such as electrical, communications and control areas; as well as hydraulic, ventilation and infrastructure for both tunnels, having 14 km – length approximately.
With the purpose of producing 2500 l/s of industrial water for Minera Escondida Concentrator Plants, Ingeniería y Construcción Sigdo Koppers jointly with Bechtel, are responsible for developing the plant, which will convert seawater using SWRO (Salt Water Reverse Osmosis) technology through different phases; the project also considers a HV power transmission line and three power substations.
