JRC 3D RECONSTRUCTOR SUCCESS CASE — EARTHQUAKE DEFORMATIONS CHECK

RESTORATION AND CONSERVATION INTERVENTION Temple of Belén, Cusco (PERU)

PDF versione italiana

PROJECT DESCRIPTION

KEYWORDS: Architectural | Conservation | JRC 3D Reconstructor | Laser scanner


The church of Belén stands on a strongly seismic territory that from its origins has undermined the structure, rebuilt several times. After the damages caused by the earthquake of 1950, the internal consolidation of the vaults and domes was carried out, in order to avoid subsequent collapses, and only recently (for the first time!) a laser scanner survey was commissioned by the Ministry of Culture in Cusco to evaluate the actual structural conditions of the church and undertake restoration work. Thanks to this important technological step, it was immediately possible to notice some serious structural problems concerning the subsidence of the cupola. An aspect that would never have emerged with traditional measurement systems.

NEEDS AND GOALS
  • Measure, analyze and document the phenomena of the degradation of the church useful for the restoration project.
  • Get for the first time an accurate survey to obtain a full view of the building.

« Working with highly technological tools allows great precision in a short time, which for the client translates into high quality at affordable prices. JRC 3D Reconstructor is an easy-to-use software: only one operator can do the whole job obtaining accuracy never seen before! »
