322 p., La adopción de la metodología BIM (building information modelling) Information modelcomo tecnología especializada en estructurar la información de los edificios en representaciones 3D ha sido ampliamente testada en la fase de diseño y construcción, pero no tanto en la fase de operación y mantenimiento. Además, su implementación en la gestión del ciclo de vida se ha desarrollado principalmente en edificios de nueva planta que han sido diseñados y construidos usando BIM.La tesis plantea un modelo conceptual de las características que tendría el proceso de implantación BIM para su uso en la gestión de la fase de operación y mantenimiento de edificios universitarios existentes que no cuenten con modelos BIM previos. El método de investigación seguido es el DSRM (design science research methodology) que plantea un proceso cíclico de desarrollo, mejora continua y evaluación que se materializa en un artefacto que da solución a un problema. El problema sería la gestión de la información relativa a operación y mantenimiento, y el artefacto, el modelo conceptual de implantación BIM como método de gestión de datos.

Residential building inspections are periodically required by public authorities. However, current approaches to storing and viewing data concerning an inspection are often collected in reports whose form and limited content hamper the rigorous assessment of the building’s state of conservation and subsequent repair of the identified damage and alterations. This research proposes a method for documenting and displaying inspection-related information in BIM models to generate a dynamic information model. Damage is spatially located by means of a parametric family, which collects the necessary information about each instance of damage and enables agile and up-to-date information extraction. The proposed method was validated in a residential building situated in San Sebastián, with a scenario designed to demonstrate its ability to support the diagnosis of causes and decision making regarding maintenance. This work demonstrates the advantages of the parametric representation of information on damage and alterations in a BIM model, which facilitates the management of a residential building’s life cycle by means of a digital twin of the building. The results shown in this research may be very interesting for researchers as well as for those whose work involves the rehabilitation of residential buildings.

Although construction is one of the largest industries in the world, it is one of the least digitised and its productivity is still very low. Excesses of time and cost are common and are even more accentuated for building renovation. Recently, the building information modeling (BIM) methodology has strongly entered in the construction sector and appears to be an effective paradigm shift. Considering all of the previously mentioned aspects, this article addresses the identification and analysis of the critical barriers of renovation and the potential for digitalisation to overcome them using BIM. The methodology that was used is based on an open innovation approach called Living Labs, where consultations with the key stakeholders of the construction process aims for a higher digitalisation to focus on real needs and fitted to the user’s requirements. Starting from a worldwide survey, the analysis of the Spanish casuistry is deepened. From the analysis of barriers and opportunities, the necessary requirements for an optimal BIM application in renovation are highlighted. After identifying the key aspects that each stakeholder’ typology has considered as relevant, a set of key performance indicators have been selected, to monitor the improvements in the renovation process when BIM is adopted.

COVID-19 had a major impact on the 2030 Agenda for Sustainable Development, and it produced a crisis in Goal 4, which is aimed at ensuring quality education, among others. In this work, a university experience that aims to solve the challenges in this complicated context by means of BIM technology is presented. On the one hand, this study focuses on the development of teaching by means of active methodologies based on real projects through BIM models, using the latest information and communication technologies, and on the other hand, it focuses on the management of the education center by means of a virtual BIM building. This allowed for, among other things, tackling the sustainable management of the measures required to prevent contagion. These BIM models made it possible, for example, to optimize spaces while maintaining social distances between occupants, to simulate the best options for classroom ventilation, and to optimize special cleaning and disinfection resources. Students who developed their learning through these BIM virtual models were not restricted in receiving online classes; they learned to collaborate from anywhere in the world, acquiring skills that allow them to effectively face real situations that are as complicated as COVID-19.

Planos, El objetivo del BIM Execution Plan es definir la estrategia para el desarrollo y control de la documentación del proyecto de ejecución de la obra “6 VIVIENDAS EN LEZO”, medidas de cooperación y control de calidad, dándola a conocer a todos los agentes intervinientes en la misma, con el propósito de crear procesos eficientes que permitan una comunicación global entre todas las partes. Debido a la particularidad de la obra, los diferentes procesos se centran en el aprovechamiento de la documentación contractual (planos, modelo 3D, etc.), adaptándola de tal manera que sea posible la utilización de un mismo archivo central, para las diferentes necesidades según disciplinas y estado de desarrollo y avance de la obra.
