During 2017, the CDC Ministry of Peruvian culture commissioned to Restauro S.A.C. the surveying of some Inca historical sites. The Tambomachay is one of these: near to Cusco, this site consists of a series of aqueducts, canals and waterfalls running through the terraced rocks. It is important to know that, till not long time ago, the measurement of these ancient walls was done by very rudimentary techniques: large sheets of millimetric paper were placed on the wall to manually trace the contours of every single stone and later manually redrawn in the CAD environment. As you can image, this workflow is incredibly time/money expensive as it requires months (years!) of work to get results always uncertain, because of drawing errors or missing details (ledge, cavity, pictures, etc.). This the reason that brought the company to operate with a laser scanner technology to face this important work. Thanks to this method it was possible to make a complete survey in less than one working day and extract rocks contour lines measurable with a millimetric precision, thanks to the JRC 3D Reconstructor post-processing software.

NEEDS AND GOALS
  • To measure, analyze and document the ancient masonry build by the Inca population.
  • To detect the exact position and verify the deterioration and/or structural failure over the time.
  • To intervene with conservation works.

    « The processing speediness and accuracy allowed us to generate 2D and 3D data with a precision impossible for the traditional surveying methods. Thanks to JRC 3D Reconstructor, we daily improve the quality and productivity of our job. »

    To complete the documentation project and illustrate the real artefact conditions, a CAD drawing with orthophotos was provided.
