Peru's investment promotion agency Proinversion has halted the bidding process for the Olmos irrigation and hydroelectric concession in Lambayeque for lack of interest. A new tendering will be launched under different guidelines. Interested companies were supposed to submit offers by 11th December. Construction was estimated to cost some US$245 million. A new scheme involves hiring a private concessionaire to invest US$112 million to develop and maintain a 41 m-high dam and 14 km tunnel. The new infrastructure is designed to pull water from the Huancabamba river to irrigate 57,000 ha of land. Visit www.proinversion.gob.pe 51/02.Investment promotion agency ProInversión and northern Lambayeque department authorities launched bidding for the Olmos irrigation and hydroelectric project. Works include developing phase one of the 37 m-high Limon dam, the 20 km Trasandino tunnel, of which 6.2 km has already been bored, and 32 km in irrigation canals. The infrastructure is designed to pull water from rivers in the Amazon river basin to irrigate land along the Pacific coast, and generate power. Previous estimates said the project would irrigate 57,000 ha of land and generate at least 150 MW of power. The government of Peru and Lambayeque will contribute US$77 million of the US$112 million project bill. Planners expect to award a 20-year concession on 28th November, 2003 with construction set for a 2004 start.

To drive at least 70% of the tunnel, a double-shield hard rock TBM must be used. When the machine drives through rock which requires structural support and lining, reinforced concrete rings will be installed as a final lining against which the thrust cylinders will push to ensure the advance of the machine. The final diameter must not be less than 4.8 m in the sections where a selective lining will be installed. The cylinders will generate a thrust of at least 2,500t. The advance speed in hard rock shall not be lower than 6 cm/min. The machine will be equipped with a segment erector. The cutting head will be equipped with 17" hard rock discs able to handle 250 kN each. The machine will also be equipped with a system to investigate the ground ahead of the face. Progress will be allowed only after prior investigation of the ground to assess the risks in the next 30 metres. There will also be a refrigeration system to lower the temperature in the working zone (pilot compartment and back-up) to allow normal work conditions for the personnel and equipment. The TBM will also be equipped with a sophisticated piloting system to make sure the tunnel is driven with a tolerance of +/- 2 cm. The sections excavated with other methods and equipment must not exceed 30% of the total tunnel length, with no geological investigation of the ground.
