This research presents an application of the Building Information Modelling (BIM) methodology to the preservation of buildings of historic value. The study of the built heritage encompasses several aspects: namely, the collection of information, the rigorous representation of the building, the identification of the applied traditional construction processes, and the classification of historic eras of construction, conservation or refurbishing. In a BIM context, the topic of old buildings is referred to as Heritage Building Information Modelling (HBIM). In order to illustrate the type of work that needs to be prepared, a building heritage case is presented. The study is focused on the identification of the historic evolution of a castle and the adjacent structural environment. The first step concerns the data collecting: several institutional repositories of old documents were consulted; technical visits to the site were performed; a large photographic survey was undertaken; and photogrammetry technology was applied. Based on the available information, the corresponding stratigraphic HBIM model of the historic complex was generated, which was associated with an accessible and well-organised database. This text aims to contribute positively to the dissemination of the HBIM in the preservation of historic buildings, and it is focused on a mandatory first step: generating a complete stratigraphic HBIM model. The model is intended to be a useful support to professionals to elaborate the preservation project, as it archives relevant data. The description of all processes from the data collection to the stratigraphic model brings an important understanding of the relevance of a primary stage performed with depth and care. This research contemplates, essentially, the topic of collecting data as essential to the performance of heritage studies.

Building information modelling (BIM) methodology has been implemented in the construction industry, reaching all sectors: multidisciplinary design development; construction planning and monitoring; and building management and maintenance. A complete BIM project aggregates several disciplines and different professionals skillsets. In order to achieve a suitable control, contributing to improve the quality of the project, a BIM manager is required. The BIM manager has the responsibility to coordinate all tasks involved in a building design, as well as the associated activities usually that are normally worked-out, complementing the project. During the development of a project, a BIM manager can access various discipline models, located in a delayering shared platform, and request responsibilities and amendments if inconsistencies are detected. The relevance of the BIM manager function is illustrated with three building cases where distinct specific projects, disciplines, and tasks were elaborated: collaboration between disciplines (architecture, structures, and construction); structural analyses and reinforcement details; quantity take-off of materials and cost estimation; construction scheduling and simulation. Although there are limitations in the software interoperability capacity, within the elaboration of a multiple stage project, BIM implementation in the construction industry has been carried out. The present study shows that the BIM manager role in projects aggregates several disciplines and experts, bringing an important improvement in the quality of the final product. A suitable BIM implementation in the construction industry needs to be supported by the most current advanced technology and in adequate BIM manager coordination.

Building Information Modeling (BIM) is a relevant booster to the modernization of construction. The adoption of digital technologies positively contributes to more agile and integrated processes in all phases of the building life-cycle, namely with regard to project management activities. The implementation of BIM has been predominant in new building projects, but the current market cycle of the rehabilitation or refurbishing of existing buildings offers new opportunities of application to be explored. This paper explores such opportunities, namely with regard to the temporary construction works involved in urban rehabilitation projects with the preservation of the façades of the original buildings. It specifically addresses the impacts of the modeling efforts of steel frames and structures needed to temporarily support façades, after the demolition of the old buildings, and until the original façade is reintegrated into the structural elements of the new building. In a BIM context, an 8D model is created to explore BIM capabilities in enabling more efficient occupation safety and health coordination and management activities in building rehabilitation projects, namely in improving and validating the demolitions and construction methods and sequencing, the scheduling of construction works, and the mandatory occupational risk prevention documents for the construction site. The development of the research was supported on the use of the available BIM software: Revit, to model the façade and the temporary steel structural system; Microsoft Project, to schedule the construction works; Navisworks, to perform clash detection analyses and enable visual simulations for occupational risk, and its identification and mitigation. The study intends to contribute to the dissemination of BIM capabilities to improve occupation safety and health in construction, namely in rehabilitation projects involving temporary structures while contributing with innovative perspectives toward higher maturity in BIM implementation and use in the construction sector.

Building Information Modelling (BIM) is a methodology supported on technological evolution achievements, and consists of a set of processes and tools that allows the creation of a digital three-dimensional model. The model centralizes information, in an organized database, facilitating the data access and the exchange between the collaborators and enterprises along all life cycle of a building. The study is focused on the application of BIM within the framework of a structural design, identifying the benefits and limitations verified in the process and indicating strategies allowing to improve the quality of the project and construction. A structural BIM model of a study case was created; using BIM based platforms, followed by its transfer to the calculation software, where the structural analysis and design were carried out. After, using the structural BIM model complemented with the reinforcements, several applications and tasks were performed, namely, the coordination and collaboration procedures, detection of conflicts analyses, production of dynamic drawings, budget estimation and environmental impact simulation of the structural framework concerning the CO2 emission. In the structural domain, the interoperability is the main problem that must be understood and the present study contributes to clarify the recurrent limitations. The research also presents the capacity of BIM methodology of using the database of the BIM model to achieve several types of tasks that normally are associated to the structural design. The study demonstrates the significant improvement in the quality of the structural design and the wide applicability of the BIM model, when compared with the current traditional sequential and fragmented process.

This paper develops an assessment of an academic implementation of building information modeling (BIM) carried out in an expert project subject of a School of Industrial Engineering. The objectives were for the students discover sustainable industrial during the design process and the students understand and participate in a real process of the implementation of industrial projects through real collaboration between academic and business contexts. The outcomes of this academic initiative were evaluated using academic results as well as students’ perceptions. Academic results were analyzed using the FUZZY VIKOR method. An analysis of variance (ANOVA) was performed to determine whether the use of BIM, the proposed university-enterprise environment and the sustainability proposal rate of the students’ projects had statistically significant effects on the results. Students´ perception evaluation was based on a Likert survey with five levels, and the results were interpreted using fuzzy k-means clustering and classification tree analysis. The results show that 77.8% of students consider that for learning, it is more effective to carry out a project related to an existing company, with the realization of the project with BIM methodology being of great value. The sustainability aspects were applied more easily thanks to the proposed methodology, and they were positively valued by the company.

This work aims to apply a systematic methodology to the analysis and graphical recovery of the “artefact” of the first lock of the Canal de Castilla (“the forge of Alar del Rey”) located in the Canal de Castilla as it passes through the province of Palencia (Spain). The canal, a great engineering work that began in the 18th century, was declared an asset of cultural interest (BIC, for its acronym in Spanish) in 1991 and was included in the National Plan for Industrial Heritage. To analyze and to obtain graphic reconstruction proposals, six main activities were developed, following three phases (study of primary and complementary technological and historical sources, fieldwork, and digital reconstruction). The reconstruction proposals were evaluated using three criteria: artefact data, the number of similar artefacts, and the performance. The weights of these three criteria were obtained using the Best-Worst Method (BWM), and the reconstruction proposals were classified using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) under uncertain conditions. AutoCAD was used to obtain detailed artefact geometric documentation (plans and detail drawings of each element). The work carried out on the artefact has allowed the reconstruction of the missing machinery and its factory, establishing a proposal consistent with the technological solutions of the end of the eighteenth century as well as with the ironworks studied and with the documentary sources consulted, recovering the memory of an artefact that is about to be lost.

The growing interest within the construction industry in the preservation, rehabilitation, and conversion of heritage-value buildings has led to the implementation of Historic Building Information Modelling (HBIM) across all sectors. The rigorously accurate representation of old construction solutions for roofs, floors, and walls, and of the decorative details and finishes, commonly used in historic buildings of patrimonial value, requires specific geometric modelling processes in order to generate relevant libraries of parametric objects. This study addresses the generation of parametric families of representative architectural geometry in the context of the conversion of a building of patrimonial value. A collection of historical information and a detailed inspection in situ, recorded by means of digital images and sketches with annotative dimensions of the architectural forms, were first carried out to support the accurate representation of the building. Several families of objects were generated, namely, guillotine windows, glazed doors, ornamental stonework, staircases, and handrails, thus creating a reference library for use in further similar building projects. The study improves the potential of the BIM process for its application to buildings with distinctive architecture in the context of the preservation or conversion of heritage buildings.

Building Information Modelling (BIM) enables the Civil engineers professional to accomplish the digital requirements and also the integration and collaboration on the elaboration of projects and maintenance of buildings. BIM methodology is currently the main subject of investigation and application in the construction industry and the education have been exploring the introduction of this issue in curricular programs. The students of civil engineering and architecture, as future professionals, must updated their skills with the most recent innovative technology and knowledge. Several academies better classified within the architecture and engineer sector, were selected and its curricular programs were analyzed: the didactic strategies of inserting BIM teachings are similar in the main concept and practice, but depending of the expertize of the school, the aspects related to architecture, structures, construction or planning are deeper taught; the level cycles of introduction BIM (bachelor, master or postgraduate), the professional courses offered to architects and engineers and the main subjects were discussed. The principal aim of the curricular research is the characterization of BIM education in distinct academies. A resume of actions and organization of topics that promotes an adequate updating of the students skills was achieved, helping BIM educators in their activity.

Research on the application of virtual reality (VR) in the construction activity, adopted normally low-immersive desktop VR or highly immersive VR, which involves using a mobile headset. Immersive VR spaces can promote a better communication between clients and specialist, around a building, in a maintenance or inspection activity, or in the real construction place, following the planned construction steps. The two primary features of VR are immersion and presence. And when linked with the building Information modeling (BIM) concept, consulting and handling information, are complementary features that can improve both technologies. Most VR environments constitute a visual experience displayed on a computer screen, but using the most advances VR technologies over the 3D BIM model a more immerse space can be handle. Simulating the real world can be improve with VR+BIM, as the interactive capacities allowed by VR software, and the access to information archive in a BIM model, supports in a more intuitive way maintenance and construction control tasks.

Building Information Modelling (BIM) is a methodology focused on the centralization and sharing of project information among all experts involved. The use of BIM platforms allows professionals to improve coordination, collaboration, and integration along with the development of all disciplines and tasks required in a complete building project. Currently, the construction industry has witnessed a growing adoption of BIM, mainly caused by the constant technologic achievements, contributing to the improvement of the integration capability of the available software. However, concerning structural design, BIM implementation still presents some difficulties, especially in the interoperability of BIM-based systems. In the present study, a structural design case was considered, using Revit as the modeling software and Robot as the structural system. A bidirectional exchange of information between the two systems was required and the interoperability capacity was evaluated. In the process, the main identified remarks concern the fundamental aspects of information sharing, collaboration, integration, and interoperability. Despite the limitations found, essentially related to the software interoperability, the BIM approach presents significant advantages in a structural project, supported by 3D visualization, model overlapping, easy accessibility to the model database, streamlined coordination, and enhanced collaboration.
