Argentina's Jujuy province government has opened bids for two river channeling tenders worth a combined 185mn pesos (US$44mn), aimed at improving access to irrigation.
The first tender involves building the Intervalles canal along the Perico river, priced at 80.3mn pesos, local press reported.
Casella and Green offered 91.7mn pesos, Coarco 93.9mn pesos and Supercemento bid 96.3mn pesos.
Work entails building an 11km concrete-lined canal from the Restitución canal to where the two rivers meet, with capacity to transfer some 10m3/s. Construction is scheduled to take 14 months and aims to minimize water losses.
The ministry also opened bids for improvement works on the Los Molinos dam on the Grande river canal, budgeted at 105mn pesos.
Benito Roggio e Hijos and José Cartellone Construcciones Civiles bid 122mn pesos, Paneline Argentina offered 126mn pesos, and Supercemento Saic placed an offer of 126mn pesos.
The project involves civil, mechanical and electrical works to restore the operational capacity of the levee system to provide better security for the town of San Salvador, which lies downstream from the dam.
Construction is scheduled to take 24 months to complete.
IDB is providing US$200mn in financing for both initiatives under the Norte Grande infrastructure program.
