We put out a tender for a historic work for Pehuajó, Buenos Aires
The execution of the project: “Construction of the potable water system for Pehuajó”, will allow supplying a future population of 35 thousand inhabitants.
The tender for the project "Construction of the drinking water system for Pehuajó" was carried out, a work highly desired by the residents of the Buenos Aires town. It will be developed within the framework of the PROAS II program and will be financed by the Inter-American Development Bank (IDB) for an amount that exceeds $6,000 million. In addition, the improvements in the network will allow supplying a future population of 35,000 inhabitants.
The event was headed by the general manager Alejandro Hoc, who was accompanied by the coordinator of the External Financing Unit, Sebastián Loggio. Similarly, the event took place on Tuesday 11/29 at ENOHSA, where the following companies presented their offers:
Riva SA: $6,640,000,000.00.
CRE Construcciones SA: $8,176,921,166.02.
TECMA SA – Ecosur Bahía SA UTE: $6,046,012,443.13.
The infrastructure to be tendered is divided into three blocks, the first of which is the supply block, and involves the execution of 18 35-m-deep perforations, which will be able to operate at a maximum extraction rate of 34m3/hr. In turn, the wells will be configured in three branches of six perforations spaced 1,300 m apart and will be linked by a PVC / HDPE collector.
In this sense, six air valves and the same number of drainage chambers are planned for each branch. Likewise, the pumping equipment will be: four of 20 HP, one of 15 HP and one of 10 HP.
Another of the blocks is the storage and pumping block, which includes the construction of a 220 m3 cistern with three 250 mm entrances, three 200 mm exits and one 500 mm towards the pump house. In the latter, a manifold will be built that will allow distribution by gravity and through three pumping lines, where 3 units of 110 kW each will be installed.
Finally, in the third block, the installation of 54.8 km of aqueduct in plastic material (PVC / HDPE) in dn 500 (half in class 6 and half in class 10) with 38 air valves and 39 drainage chambers is planned. |
