Cultural Heritage buildings face major challenges trying to combine a usability function with conservation and restoration obligations. Suitable conservation involves a complex set of activities, some concerned with historical documentation (functionality, construction materials, physical developments, etc.). Other activities require a geometrical description in order to detect pathologies related to walls tilting, displacements or roofs and beams deformation. Here, we propose a methodology that takes into account all those requirements when modeling a key 14th century Cultural Heritage building in Granada (Spain): Corral del Carbón. Known in the Moorish period as “Alhóndiga”, the building was used as an inn and a warehouse for merchandise. We survey the building with the most accurate techniques currently available (scanner laser and photogrammetry). After surveying it, we model the building at different levels of detail taking into account the various phases known to comprise the building. Finally, we propose an HBIM (Heritage Building Information Modeling) for building maintenance and facilitate its sustainability and usability over time.

This research aims to start the process of the revitalization of peri-urban spaces with high landscape and cultural potential, dotted with a series of heritage landmarks that allude to the recent industrial, economic and cultural history of the region, currently semi-degraded or abandoned, as is the case with the impressive and steep miller landscape of the Tajos de Alhama de Granada. To achieve this, it is proposed to carry out a comprehensive documentation (historical, cartographic, planimetric, photographic and photogrammetric) of the study area since, until now, there were no similar research studies. The application of an organized and structured method of work, documentation and diagnosis using the tools and graphic techniques of the 21st century has offered extensive results that have been turned into a rigorous and systematic catalog. This catalog will serve as the basis for the promotion of integrated action plans for the recovery of this urban edge, with the triple objective of the rehabilitation of buildings of architectural interest, rehabilitation of the surrounding public space and consolidation of the historic complex that makes up the mills, the river, the landscape and the city. We conclude that the enhancement of the cultural heritage landscape of the Tajos and the guidelines provided for the rehabilitation of its historic water mills, with possible compatible uses (tourist, cultural or administrative), will favor the conservation and sustainable revitalization of such an exceptional heritage site.
