Question/Instruction: Who has been subcontracted for the civil works of the project and what is their timeline for completion?

Given material: Civil works have begun on the estimated $280 million Iran Aluminium Company (Iralco) project to build a 110,000-tonne-a-year (t/y) aluminium smelter in Arak. Work on the plant started in May after Iralco successfully proved to local authorities that setting up the plant next to its existing 120,000-t/y smelter would be environmentally safe. The smelter was initially planned to be located at a site 30 kilometres away from Arak (MEED 21:12:01).
China Non-ferrous Metal Industry’s Foreign Engineering & Construction Company (NFC), which was awarded the contract to build the facility in November, has subcontracted the civil works to the local Tecnicon, which plans to complete within 12-15 months.
NFC’s contract covers basic engineering, supply of equipment and its own technology for the smelter, supervision, commissioning and training. Key equipment, including transformers and compressors, is set to come from European companies. The project is due to be completed within three-four years.
Iralco is negotiating with international companies for the construction of a petroleum coke calcining plant (MEED 26:7:02).
