Toward deep impacts of BIM on education

Žiga TURK, Andreja ISTENIČ STARČIČ

Frontiers of Engineering Management 2020, Volume 7, Issue 1,   Pages 81-88 doi: 10.1007/s42524-019-0035-2

Abstract: Building information models (BIM) provide a way to represent buildings and communicate about them. In teaching engineering, we also need representations of buildings and are communicating knowledge about them. While teaching engineering we refer to the very same real-world objects that have an explicit conceptualization in BIM. This explicit conceptualization did not exist in the age when design communication relied on drawings and documents. The question that this paper asks is this: due to BIM, communication in the industry has changed. Should communication of engineering knowledge – teaching – change as well and how? While much has been written about teaching BIM and incorporating BIM into the curricula, this paper is exploring the general impact of BIM on engineering education. It grounds earlier work (Turk, 2018) on insights from pedagogy. Five scenarios of the interplay between BIM-influenced engineering communication and teaching are presented. The paper argues that ignoring BIM may create a cognitive dissonance between academic learning and industrial work. We are finding that the impact of BIM is twofold: vertically there is a need to establish a reference between knowledge concepts (in teaching building) and information objects (in building information models). Horizontally BIM is an integration technology that allows for a more holistic design and planning. Both the language of individual courses as well as cross references and synergies among courses should change. A “T” style structure of the courses around BIM is proposed as a basis for integrated curriculum. Pedagogical approaches based on deep learning, model based learning and project based learning are suggested.

Situational Awareness in Construction and Facility Management

Burcu Akinci

Frontiers of Engineering Management 2014, Volume 1, Issue 3,   Pages 283-289 doi: 10.15302/J-FEM-2014037

Abstract: Engineers and managers involved in construction and facility/infrastructure operations need situational awareness about the as-is conditions when making daily decisions and developing short- and long-term plans. Yet, currently situational awareness of engineers is often challenged due to missing data and the available data not being in a format that is easily accessible and actionable. Advances in reality capture technologies, such as 3-dimensional (3D) imaging, in-situ sensing, equipment on-board instrumentation and electronic tagging, streamline the capturing of the as-is conditions on job sites. The data collected from these technologies, integrated with building information models depicting the as-planned conditions, can help in creating and storing the history of as-is conditions of a facility to support a variety of decisions that engineers and managers need to make. While the opportunities associated with integrating building information models and data capture technologies are compelling, several challenges need to be addressed through research for effective usage of these technologies. Such challenges include assessing the accuracy of the data collected at the field, developing and evaluating data processing and data fusion approaches, formalizing integrated representation of building information models and sensor and other relevant data, and investigating and developing approaches for analyzing and visualizing such integrated information models. This paper provides examples of recent research studies done at the Civil and Environmental Engineering Department at Carnegie Mellon University that demonstrate opportunities associated with integrating building information models and sensor information for facility operations.

Rapid thermal sensors with high resolution based on an adaptive dual-comb system Special Feature on Precision Measurement and Inst

Yi-zheng GUO, Ming YAN, Qiang HAO, Kang-wen YANG, Xu-ling SHEN, He-ping ZENG

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 5,   Pages 674-684 doi: 10.1631/FITEE.1800347

Abstract:

We report a high-resolution rapid thermal sensing based on adaptive dual comb spectroscopy interrogated with a phase-shifted fiber Bragg grating (PFBG). In comparison with traditional dual-comb systems, adaptive dual-comb spectroscopy is extremely simplified by removing the requirement of strict phase-locking feedback loops from the dual-comb configuration. Instead, two free-running fiber lasers are adopted as the light sources. Because of good compensation of fast instabilities with adaptive techniques, the optical response of the PFBG is precisely characterized through a fast Fourier transform of the interferograms in the time domain. Single-shot acquisition can be accomplished rapidly within tens of milliseconds at a spectral resolution of 0.1 pm, corresponding to a thermal measurement resolution of 0.01 °C. The optical spectral bandwidth of the measurement also exceeds 14 nm, which indicates a large dynamic temperature range. It shows great potential for thermal sensing in practical outdoor applications with a loose self-control scheme in the adaptive dual-comb system.
