Reference Project

Analytical and Research activities in the monumental complex of Alhambra and Generalife

Site description

The mosque and the baths were built during the reign of Muhammad III between 1302 and 1304 along Calle Real. The baths were placed for public use since the one located in the Alcazaba was intended for private use for healing purposes, while that of the royal house and those located inside the former convent of San Francisco were for exclusive use of the inhabitants of those buildings. The mosque and the baths like other parasitic constructions that were located along Calle Real, between 1923 and 1936, following the Catholic rule, were either entirely demolished, as in the case of the mosque, or partially demolished and reconverted with new functions as in the case of the bathrooms. The original floor of the baths underwent several changes and its rooms were converted into the famous house of the artist Antonio Barrios, nicknamed the Polinario. The tavern "La casa del Polinario" acquires great fame in the 19th century, becoming a famous meeting point for all the artists who have worked on the Alhambra.

Documentation Methodology

The documentation actions were carried out in 2018. A TLS survey with Faro S150 Series laser scanner, counting a total of 120 scans were carried out divided by floor level; a fast survey through the mobile laser scanner tool with SLAM Kaarta Stencil & Contour technology. In parallel to the laser scanner acquisition operations, a photogrammetric acquisition campaign was divided into a close-range shooting phase from the ground of all the internal environments and the building's external wall portions, and a shooting phase using a Spark DJI drone for the acquisition of the roofing system and some internal decorations positioned at high altitudes.

The case of the Alhambra mosque bathrooms was an opportunity to use the data acquired from the digital metric survey in two different modes of representation: one aimed at representing details through two-dimensional design, the second at experimenting with digital collaborative modeling. The metric data acquired during the survey campaign conducted by the DAda-LAB Laboratory (UNIPV) in collaboration with the Smlab laboratory of the University of Granada is based on the two experiences. To guarantee an integrated 360 ° survey, different tools were used on-site, thus defining different data information levels. From a more general descriptive level, the study of the relationship between the monumental complex of the baths and the entire museum system of the Alhambra; at a more specific level of detail aimed at studying and cataloging the individual architectural components of the bathroom environments. The integrated morphometric database was used for a dual function. It was used to realize two-dimensional drawings of a "traditional" mold through the revision on CAD for the description of the detail of the wall faces. This type of representation remains the most effective method for describing the detail, with a high level of accuracy of the wall texture for analyzing the walls. Secondly, it was used as the basis of the construction skeleton of the HBIM three-dimensional model, importing the cloud into the Revit environment and using it for extrusion operations and the comparison analysis between modeled object and detected object. .
