Observations
Our client required a traditional system, solid, flexible, without beams, maintenance zero and ultra-fast assembly. Under these conditions he chose PRENOVA.
They are big interior spaces; the metallic windows go from the floor to the ceiling.
Built with the PRENOVA system, the precast is done in situ, using the patented system created by arch. Ricardo Levinton.
On top of an entoscado soil the sanitary installation is placed; then a lightweight PRENOVA slab with spheres is casted. Another option can be a PRENOVA slab done over piles on a vegetal soil that can be use as a natural cast.
Simultaneously the slabs and the facade and interior panels are casted one on top of the other.

These are casted over the foundation pit or one on top of the other in amounts maximum 10 panels, near to the construction site to avoid transportation. They are assembled by a crane of at least 18 tons.
The exterior panels consist in: a concrete layer of 7 cm, a Styrofoam layer of 4 cm and an exterior facade layer of 6 cm. The interior panels are made of solid concrete and it thickness is 12 cm.
The ceiling panels are similar, although the thickness-from 12 to 20 cm- varies depending the distance required to span.
The surfaces come out of the cast perfectly polished. The sanitary and electrical installation is included in the casting process. The required working crew is not specialized. 6 hours by square meter is the required working time (2 hours per square meter of panel).
The metallic windows are placed in the cast. 100 covered square meters are done in an 8 hour working day.
The structure is based in a total monolithic composition achieved by the wet assemblage and casting of the reinforcement steel bars in the unions is approved by the INPRES, the CAT, the Minvu Chile and considered by CIRSOC and all the world as seismic resistant and conventional, considered therefore a traditional structure.
