BIM Application for Sustainable Teaching Environment and Solutions in the Context of COVID-19

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

Analysis of the State of Building Conservation through Study of Damage and Its Evolution with the State of Conservation Assessment BIM Model (SCABIM)

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.This reserach is funded by UPV-EHU grant number US19/10

Challenges for Digitalisation in Building Renovation to Enhance the Efficiency of the Process: A Spanish Case Study

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.This work has been developed within the project BIM4Ren. The project has received funding from the European Union’s Horizon H2020 research and innovation programme under Grant Agreement No. 820773.

Implantación de la metodología BIM en el Grado en Fundamentos de Arquitectura

En la actualidad, la nueva metodología Building Information Modeling (BIM) se ha establecido como el método de diseño, generación y gestión de datos más importante dentro del proceso de construcción de un edificio, así como de su posterior gestión y mantenimiento. Este Proyecto surge por el requerimiento, tanto a nivel europeo como estatal, de implementar la nueva metodología BIM en el ámbito de la construcción. El objetivo de la investigación es proponer cómo debería realizarse la implantación del sistema BIM dentro del Grado que actualmente se imparte en la ETS Arquitectura de Donostia (UPV/EHU). Tras cinco años de trabajo, en el estudio se recoge la labor desempeñada durante este periodo 2018-2022 y se concreta la forma de llevar a cabo dicha implementación. El fin último del siguiente documento es que cuando la implantación de la metodología BIM en el Grado en Fundamentos de Arquitectura sea un hecho, los egresados estén familiarizados con dicha metodología, para ser capaces de incorporarse a un mercado laboral que precisa cada vez más de estos conocimientos.Esta publicación ha sido posible gracias al apoyo de la ETS de Arquitectura de San Sebastián – UPV/EHU, el Departamento de Arquitectura de la Universidad del País Vasco – UPV/EHU y el Departamento de Planificación Territorial, Vivienda y Transportes del Gobierno Vasco

Estrategias para el uso de BIM en el Facility Management de los edificios universitarios del Campus de Ibaeta de la UPV/EHU

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

Energy Efficiency versus Heritage—Proposal for a Replicable Prototype to Maintain the Architectural Values of Buildings in Energy Improvement Interventions on Facades: The Case of the Expansion of San Sebastián

The implementation of energy efficiency improvements in facades, such as ventilated facades or External Thermal Insulation Composite Systems (ETICS), is leading to a widespread modification of these structures. The lack of appropriate regulations to curb the destruction of the built heritage, particularly in historical centers, has been identified. In response to this issue, a project has been developed to create a prototype for determining regulations for facade interventions. The Design Science Research Methodology (DSRM) has been employed in the development of the prototype, which has been tested in a case study of the ensemble formed by the Cortázar and Oriental expansion areas in San Sebastián. The initial prototype has been outlined, corrected, and improved in an iterative process, resulting in a final prototype that enables a faster, more rigorous, and efficient understanding, characterization, classification, study, and definition of intervention criteria, measuring the vulnerability of buildings to these interventions quantitatively. In this study, the vulnerability is defined as the risk that a facade will alter the characteristics of its architectural style and distort the reading of streetscapes that belong to a period with a clearly defined character. The case study results have been compiled into intervention criteria sheets for each of the studied buildings. This material has been presented to the relevant public authorities, with the hope that it may lead to a modification of current legislation, thereby helping to curb the loss of architectural heritage identity.This research was funded by Gune+
