A Digital Perspective on Architectural Heritage Assessment and Management: As-it-is BIM for Heritage Buildings
摘要
New digital technologies such as building information modelling (BIM) enables addressing complex tasks for sustainable management of Architectural Heritage. BIM models allow integrating historical, technical and service conditions, facilitating management plans suitable to social, cultural, and economic value of Architectural Heritage. However, the unique requirements of Architectural Heritage need tailor-made solutions for BIM modelling techniques. This study aims to implement a methodology for creating BIM models that include historical, technical, service data and tailor-made materials for Architectural Heritage Management (7D BIM). This approach includes the identification and selection of a case study building located on the Historic Campus of the University of Alcalá, World Heritage Site by UNESCO; a digital base model on the current state; data collection of restoration, conservation and retrofitting actions carried out; in-situ measurements of historic and repair materials by non-destructive testing (NDT); monitoring indoor and outdoor environmental conditions; and laboratory experimental simulations of functionalized repair mortars suitable for refurbishment. This methodology may provide essential knowledge about digital repository of Architectural Heritage Model and in-situ data measurements to support decision-making regarding habitability, energy efficiency and conservation in heritage buildings to fulfil the nowadays reuse requirements.
