Featured Application: This approach allows the assessment of building information modeling (BIM) implementation in the formal teaching system, taking into account the student perceptions of BIM in the engineering project course.Abstract: The building information modeling (BIM) methodology is becoming a mandatory requirement in the development of projects within the world context. Consequently, technical schools have been introducing BIM in their curricula. The present study aims to evaluate student perceptions concerning the advantages and difficulties of incorporating BIM into the formal teaching system as part of the degree in industrial engineering. Students' understanding and satisfaction were analyzed while using BIM in the development of the practical component of a didactic industrial project. The evaluation was based on a Likert survey with five levels, and the results were interpreted using a factor analysis and ascending hierarchical classification. To identify possible relationships between student satisfaction with the BIM implementation and the factors obtained, a multiple regression analysis was performed. It was determined that students have a high perception of BIM utility and consider the use of the BIM tool that is intuitive and easy to learn, including during the autonomous learning process. The results show a direct correlation between the benefits of BIM implementation in industrial projects and the advantages of defining teamwork within collaborative projects. The incorporation of BIM as a mandatory subject in the industrial engineering curriculum appears to be successful, and the results are encouraging.
The methodology and technology associated with building information modeling (BIM) provide architects, engineers, and historians with concepts and tools that support the development of heritage projects. However, this specific form of BIM orientated towards buildings of patrimonial value—known as historic building information modeling (HBIM)—requires a distinct and additional view, accounting for aspects which are normally not attended to on projects involving new buildings. In an HBIM context, the parametric modeling process, the basis of any BIM procedure, involves the study of shapes, patterns, or standards for the establishment of particular collections of parametric objects, as well as the record of the available technology used to capture digital geometric data. In addition, all the information collected and generated through an HBIM process must be adequately managed, maintained, and archived. In the present study, we intend to list the most recent features of HBIM, based on a bibliographic review, encompassing distinct building situations (preservation, restoration, rehabilitation, and structural assessment); different technical equipment (drones, scanners, and photogrammetry); as well as diverse forms of geometric characterization (patterns, geometric rules, or curve generation) and ways of archiving data (stratigraphy, old drawings folders, or as-built models). With the aim of identifying, as an overview, we have presented the principal modeling strategies, technologic devices, and archive procedures, as a contribution to systematizing and organizing the dispersed practical and theorical studies related with HBIM.
The implementation of building information modeling (BIM) has become a reality worldwide, not only because of the advantages it offers, but also because of the obligatory nature of its use in construction and civil engineering projects in various countries around the world. An intervention project on an industrial heritage property requires a methodology that considers the condition of the building over time and its value for new use. The advantages of working with a precise 3D model that integrates engineering data in a collaborative work environment makes BIM and heritage BIM (HBIM) very useful tools in a project whose objective is the recovery of an industrial heritage real estate property. This work is part of the academic implementation of BIM in university technical education centers and aims to establish a methodology for shared and collaborative group work in a BIM environment through a Spanish industrial heritage case study of a flour factory dating to 1865. A rigorous historical study and the elaboration of a central BIM model loaded with real content on the industrial complex have allowed the immersion of the students into the BIM methodology, as well as the generation of a value proposition for the exploitation of the factory.
The American Academy of Ophthalmology and the National Heart, Lung and Blood Institute recommend patients with sickle cell disease (SCD) undergo dilated funduscopic exams (DFE) every 1–2 years to screen for sickle retinopathy. There is a paucity of data on the adherence rate to these guidelines; a retrospective study was performed to evaluate our institution’s adherence. A chart review of 842 adults with SCD, seen 3/2017–3/2021 in the Montefiore healthcare system (All Patients), was done. Only about half of All Patients (n = 842) had >1 DFE during the study period (Total Examined Patients, n = 415). The Total Examined Patients were categorized as screening, those without retinopathy (Retinopathy−, n = 199), or follow-up, including individuals previously diagnosed with retinopathy (Retinopathy+, n = 216). Only 40.3% of screening patients (n = 87) had DFE at least biennially. As expected, there was a significant decrease in the average DFE rate of the Total Examined Patients after the COVID-19 pandemic started (13.6%) compared to pre-COVID (29.8%, p < 0.001). Similarly, there was a significant decrease in the screening rate of Retinopathy− patients from 18.6% on average pre-COVID to 6.7% during COVID (p < 0.001). This data shows the sickle retinopathy screening rate is low and innovative approaches may need to be employed to remedy this issue.
