BIM Technology and Changes in Traditional Design Process, Reliability of Data from Related Registers

Abstract

With the new technology of creating building design, many changes of traditional processes have to be set in order to reach project documentation and project design itself in higher quality level. As a traditional project documentation is changing in “digital twin” of building work, the way of building work design changes too. Building design and project documentation do not serve only for the building construction, maintenance and operation. Project documentation is the output, also the input – both at the same time - in connection with further building legislation, landscape planning, etc. BIM model, nowadays the highest quality of project documentation, should communicate with many related registers. Important basic information is as an input for the project design, afterwards information from the project design should be reflected as an output for the enlisting in related registers. Due to the absence of efficient digitization of the construction industry, the relevancy, correctness and reliability of information in the related registers is not very high in the Czech Republic, at this time. Digitization of construction industry and implementation of BIM technology promises many benefits. The magnitude of these benefits depends on how the data exchange is modified in the construction process during the whole building lifecycle. This paper reveals possibilities of basic principles of the new way of design using BIM technology, connections of BIM model data and related registers and their data exchange in the environment of Czech Republic´s legislation. The more correctly processed the model of the building work, the better and more reliable information for future designs.

BIM-Based Digital Twin and XR Devices to Improve Maintenance Procedures in Smart Buildings: A Literature Review

“…Such data can also be used in the construction phase to detect any misalignment in the building elements by using it as a comparison basis with the constructed element, in order to avoid any further necessary reparation [45]. A BIM-based DT can also be used to improve existing operations in the building lifecycle, such as optimising equipment usage or global maintenance costs [32,33,36,40]. Kaewunruen et al show the example of using an enhanced BIM to improve the management and the maintenance cost of a railway turnout system according to its condition and track usage [32].…”

“…Research studies have been done to highlight that, if used from the start of the project, BIM can contain static and semantic data of the entire project, such as providing digital continuity throughout its lifecycle [16,28,40]. To ensure this continuity and the interoperability between the different phases of the project, some authors have proposed methodologies and points of concern to prevent any loss of data between the different phases [16,28,29,32,[34][35][36][37]40,41]. Prušková et al propose such a methodology to explain how the data are transferred throughout the building lifecycle [36].…”

Prušková et al propose such a methodology to explain how the data are transferred throughout the building lifecycle [36]. It has been shown that the centralised property offered by a singular BIM-based DT can improve data access by the different stakeholders of the project [16,29,32,33,38,40,41].…”

“…One of the main issues concerns the lack of up-to-date data [28,33], usually caused by incorrectly anticipating the need of later phases and by a lack of communication between the different actors in these phases. The stakeholders often use specific BIM models for their current phase [16], making it necessary to improve the formalisation and standardisation of data to provide interoperability between the phases but also between the various systems inside the building [16,28,31,33,35,36]. As an example, Peng et al have observed that the specificity of specific equipment, such as medical systems included in the BIM, complicates the automatic data recuperation and analysis, but also the data exchange between the different phases of the project [35].…”

“…Lack of standards [16,28,31,33,35,36] Lack of up-to-date data [28,33] Privacy issues [29,31,35] Lack of organisational strategy [29,35,36,41] The improved sharing of data also provides an issue concerning the security and the privacy of data [29,31,35], concerning who can see and use the collected data and who is proprietary of these data. It brings about the need to provide new organisational strategies concerning the roles of each stakeholder, but also on the implementation of the BIM-based DT into the existing strategies of the building exploitation [29,35,36,41].…”
