At the end of July, the Soletanche Bachy Argentina teams have completed the “OHMSA Silos” project in Bahía Blanca (Province of Buenos Aires, Argentina). OHMSA is part of the GLENCORE Group, the leading grain exporter in Argentina.
The contract consisted in design and build the deep foundation and the civil work in reinforced concrete with columns and circular slabs for its three new silos for soybean storage, together with the elevator pit and the floors required for the project to extend its facilities.
The foundation proposed by Soletanche Bachy Argentina, which supports 7000tn per silo, consisted in a mixed system of barrettes of 2.70m x 0.60m and CFA piles of 800mm, all to a depth of 18m. The civil work involved the production of circular slabs, 18.75m in diameter, resting on columns and walls 5m high, as a continuation of the barrettes and piles.
The cylindrical structure of the silos, based on the circular slabs built by Soletanche Bachy, is 40m high and produced in reinforced concrete using sliding falsework for the COMASA Company, under a different contract.
As an integral part of our activities, we also carried out three static load trials which enabled us to confirm the capacities envisaged in the design, and integrity testing over all the elements, for the purpose of verifying their quality.
The work necessitated working double shifts and it was completed in compliance with the high quality and safety requirements of the Soletanche Bachy group, with no time lost on accidents, and therefore meeting the requirements of our client, GLENCORE, and of the works supervisor, WORLEY.
