Iran, Lorestan - ir/22

Hydropower

Pöyry has been awarded a EUR7 million engineering services contract by Sepasad Engineering Co. to undertake engineering services during the implementation of the 450 MW Rudbar-e-Lorestan hydropower project. Previously, Pöyry carried out technical studies for the project. The Rudbar-e-Lorestan dam and hydropower project will consist of a 180 m-high roller compacted concrete dam to create a reservoir with an estimated gross capacity of 228 million cubic metres. Water from the reservoir will be diverted through a 3 km-long headrace tunnel into the adjacent valley and hence in twin surface steel penstocks down to the surface power house on the bank of the Alkan river. The Rudbar-e-Lorestan hydro project is to be constructed in the upper reaches of the Dez catchment in the Zagros Mountains. Visit www.poyry.com 26/07.

Iran, Tabriz - ir/21

Metro

Contractor Alamoot to build 7 km twin-tube metro tunnel for client Tabriz Urban Railway Organization (TURO). Excavated diameter is 6.8 m and inner diameter is 6 m. Two NFM Technologies EPB TBMs will be used. Lining with prefabricated concrete rings, with five 1.4 m-wide segments and key per ring. The line also includes one 80 m-long station every 800 metres. Click here. Visit www.nfm-technologies.com and www.alamoot-co.com 03/06.According to conducted feasibility studies, three routes have been selected with a total length of 44 km and 60 stations for the metro in Tabriz. Priority has been given to Line 1 with a total length of 18 km and 28 stations. This route starts from EI Gloi (southeast part of the city), passes through Bahman 29 Boulevard, Emam Khomeini Avenue (main street of the city), Khayyam Avenue and ends up in Lale district. The first part of this line is under construction and the second part is being designed. At both ends of the line, main terminals and depots have been designed for wagon maintenance and repair.Construction of Line 1 is divided in several phases. Phase one starts at EI Gloi terminal and ends at Rah-no-maee. This section is a shallow tunnel and is under construction by cut-and-cover method.Phase two starts at Rah-no-maee and ends at Tabriz University Round Square. This section comprises a pre-stressed elevated bridge starting from Shahriyar hotel and passing over Bahman 29 Boulevard and the entrance of Vali-Asr Street and then gradually reaches ground level in front of Bahman 29 hospital where station number six and the Tabriz Urban Railway Organization (TURO) central control room and head office building will be located. The rest of line will be a shallow tunnel up to Tabriz University Round Square.Phase three starts at Tabriz University Round Square and ends at Khayyam Avenue. This section will be constructed as a deep tunnel for a total length of eight kilometres due to existing city life, narrow avenues and tall buildings along the avenues. Excavation will be done by an EPB shield machine supplied by NFM Technologies. The tunnels will be twin tubes of 6.88 m diameter.Phase four starts at Khayyam Avenue and ends at Lale terminal. This section is being designed and alternatives are elevated bridge and shallow tunnel. Click here. Visit www.tabrizmetro.org 06/06.

Iran, Kerman - ir/19

Water Supply

  An international JV formed by Jaeger Bau, Oestu Stettin, SELI, Arvin Engineering and Wirth won a contract to build the Kerman long-term water supply project. The project is designed to supply water to the city of Kerman in southeast Iran, by utilizing the water of the Jazmourian watershed. A 63.5 km north-south running tunnel will be built, excavation diameter of 4.04 m. Two Wirth double-shield TBMs will be used. The northern portal is located approximately 45 km SSW of Kerman while the southern portal is approximately 7 km southeast of Rabor. The maximum overburden of the tunnel is 1,160 m. The geological formations are mainly of volcanic origin, with lesser intrusive rocks. Two ventilation shafts are foreseen. The water transfer tunnel will be excavated from each side of the Kuh-e-Lalehzar mountains, with two drives of approximately 32 km each. The tunnel will partly be lined with prefabricated concrete segments. Logistics will be the project's challenge to build the two tunnel sections in a mountainous hinterland and into the city. The project's engineers are Arvin Engineering of Iran. The client is the Islamic Republic of Iran's Kerman Regional Water Authority. The contract amounts to EUR134.6 million and includes the financing, planning and execution. Financing by Bank Austria Creditanstalt and Oesterreichische Kontrollbank. Construction time: 60 months. Although Kerman is close to Bam, a historical city recently destroyed by an earthquake, the tunnel is not threatened by a seismic zone.

Awarded to French companies using Zokor TBMs before the Islamic revolution of 1979, the metro has instead been built by Iranian companies with Chinese technical help. The 9.4 km-long line, the first in the Gulf, was built over a period of 13 years at a cost of about $383 million and 40 workers lives. Several years ago, a main street in downtown Tehran opened to swallow cars and people when the one of the tunnels caved in. The line, which has nine stations, connects central Tehran with the western suburb of Sadeqieh and merges with a regular railway service to Karaj, 30 km west of Tehran. The metro capacity is 40,000 pax/h and it will commence limited operations on 21st March. An extension and three more lines totalling 100 km are planned. More information on the TBMs from thesegmentman@aol.com March 2000.Construction of $500 million extension of Tehran's underground system will begin in 2002 for opening in 2010. China has agreed a $100 million loan to extend a line to the Ghazvin region, west of Tehran, and another $29 million to complete a line in the western suburbs.

Visit www.avand.net and www.iraniantrade.org 37/01.Line 7 of the Tehran metro is divided in two lots of an approximate total length of 26 km. The bored diameter is 9.14 m whereas the outer and inner diameters are respectively 8.85 and 8.15 m. Geology consists of alluvium from coarse grain to fine grain and maybe bedrock. The owner of the project is Tehran Urban and Suburban Railway Company (TUSRC). Sepasad is the general contractor and subcontracted the construction to SELI for one section and Hara Institute for the second section.SELI will excavate the north-south lot (14 km) using one refurbished, upsized dual mode EPB TBM made by SELI using some minor components of a Lovat TBM used for the Torino metro (mainly cylinders and back-up). Lining rings will be placed as per a 6+1 segment configuration with 35 cm-thick 1.5 m-long bolted universal segments and bi-component grout pumped to the extrados. The maker of the segments moulds has not been selected yet. Same of Milan has been chosen as supplier of the segments moulds. Tunnelling excavation is scheduled to commence in April 2009 and will last three years. Hara Institute is the subcontractor of the west-east lot (12 km). SELI will supply the TBM and back-up equipment for this lot and will be responsible for the TBM assembly and excavation of the first 300 metres.
