AHI Architectural Heritage Intervention

“Contributing to enhancing our heritage, as the way forward for 21 st Century architecture is our raison d’être; to emphasize a diverse, rich vision that necessarily complements the intervention is our mission, and achieving it with reflexive and purposeful efforts is the challenge”.

This project, founded in, and directed since, 2011 by Ramon Calonge, Oriol Cusidó, Marc Manzano and Jordi Portal, architects and members of the Group of Architects for the Defence and Intervention in Architectural Heritage (AADIPA), has, through the years become a platform that includes four actions that are both independent and transversal.
 
The European Award, a biennial event that brings together and showcases the multiple approaches of intervention in Europe.

The International Biennial, a framework that serves to compare and gain closer insight of quality interventions in architectural heritage in non-European countries.

The digital Archive, a live and open window that provides a panoramic view of interventions in the history of our surroundings.

The Forum, a meeting place where you can participate in on-going debates about the main preoccupations and lines of thought about interventions in architectural heritage in Europe.

Roofs of Santiago de Compostela Cathedral

The analysis of the weather conditions in Santiago de Compostela which were affecting to the stonework, it was determined that on average: The roofs collected over 5 million litres per year. From previous reports and diagnosis it was deemed of vital importance to propose a back-ventilated roof. The concrete slab inherited from the past, which constituted the fields of the roof, was repaired to improve its flatness. On this layer was put the waterproofing coat and next, the roof compact system, was substituted by the new one which consists of an aluminium substructure, a kind of pairs and straps, on this structure was deposited the stone epidermis of open dry junctions, sloped and stepped similar to the historic one. This solution will make it possible that visitors could walk on the Cathedral's rooftop. In the restoration project were included archaeological works, being carried out 23 probes that allowed to make a record of: the disappeared towers, the gothic stepped gable and the hydraulic system always on process of building.
