The Argo structural system consists of a plane prestressed reinforced concrete slab with an open end; the slab is combined with pillars (including PVC rainwater down-pipes and overhead travelling crane bracket if needed), prestressed reinforced concrete “TH” ground beams, closing gables

The Argo diminishing cross-section allows water to flow on the external edges, thus bypassing the construction of inside building sewer and drainage systems; in the event of extraordinary rainfalls the extrados shape and width allow a remarkable storage capacity and a fast draining of waters.
