Roof Renovation for "Locanda alla Posta" in Venice, Italy

In 2017 Scaldaferro, a Torrone manufacturer in Dolo (Venice) and owner of the historic building "Locanda alla Posta", contracted Ri-Legno S.r.l., a leading company in timber reconstruction, to deal with the building's 55.7 ft x 52.4 ft timber roof.
The existing roof was severely deteriorated and decayed, and therefore, after a careful inspection, Ri-Legno decided to rebuild the roof from scratch and recreate the truss configuration according to the original construction.

Structural Design

The Ri-Legno planning office designed the structural framework using structural analysis software RFEM and the add-on modules RF-DYNAM Pro for evaluating the structure's dynamic behavior and RF-TIMBER Pro for the load-bearing timber member design.

The roof geometry took into account the existing construction scheme: Piedmontese timber roof trusses (orditura alla piemontese) and Italian roof trusses (capriata all'italiana). The roof trusses have a span of approximately 55.7 ft and include struts providing intermediate support to the rafters. The rafters running perpendicular to the ridge line support the roof covering with slab-like hollow clay bricks as well as monk and nun tiles.

The truss beam joints were reinforced with steel elements to prevent the movement of structural components. Additionally, special consideration was given to the structure's placement process by developing an ad hoc model in RFEM to estimate the roof's stress state during lifting.

A unique feature of this roof renovation is that the 2,906.2 ft² roof was completely constructed on the ground (to ensure that construction under the roof could continue during this time), then lifted and placed as a block on the existing vertical masonry structure.
