Data Interoperability Assessment Though Ifc for Bim in Structural Design – A Five-Year Gap Analysis

Abstract

In the last years the aec (architecture, engineering and construction) industry has been influenced by the development of building information modelling (bim). With the creation of complex systems, the need for efficient in­teroperability arises. Based on a study of bim interoperability dimensions and its levels, this research presents an inter­operability assessment of bim system in the structural domain, especially considering cast-in-place concrete structures, since they present some special challenges for system interoperability. This assessment was conducted by experiments that imported and exported structural models and structural elements through a non-proprietarz standard for bim mod­els (ifc- industry foundation classes). The experiments were conducted twice, with a five year gap from each other, so the evolution of the interoperability could be assessed as well. The results showed that some special characteristics must be considered in order to achieve efficient interoperability for cast-in-place concrete structures – these structures are monolithic and they have reinforcement steel bars that need detailing. Also, the research showed that in the five-year gap there were evolutions in interoperability, like in object identifiers, which had a considerable improvement. However, some of the major problems remain, such as overlapping of structural parts.

Interoperability Analysis of Ifc-Based Data Exchange Between Heterogeneous Bim Software

“…This study adopted the scoring mechanism in Muller et al (2017) to evaluate the interoperability in terms of test criteria. Similar to the Likert scale, three scores were designed to evaluate the accuracy of exchanging data: 1 for completely correct, 0.5 for partially correct, and 0 for completely incorrect.…”

Introducing BIM in Curricular Programs of Civil Engineering

“…Around the world BIM methodology have been adopted mainly in public buildings : In Europe the first countries in using the methodology were Finland, Norway, Sweden and Denmark and they established some strategies and rules to support BIM collaborative environments (Muller et al, 2017), [8] (Ignatov et al, 2019). Other countries like Singapore and China were BIM is widely applied established new ifc objects related to buildings and The students of Civil Engineering have taken benefit of the new opportunities in their future activity, adding BIM knowledge and with it improving their skills (BIM Strategy Report, 2012).…”

Project Management after the BIM Introduction: Paradigm Shift or Reiteration?

“…Despite that, BIM implementation is increasingly growing worldwide according to Chew andRiley (2013), McGraw Hill Construction (2014), Gledson (2015), Edirisinghe and London (2015), Madeira Filho (2016) and Null (2018). On the other hand, numerous bibliographies also report the difficulties that companies and professionals face when they try to integrate BIM in their work routines, regarding interoperability (Wu and Zhang 2019;Karan and Irizarry, 2015;Arayici et al 2018;Muller et al 2017), intellectual property and copyright rights (Porwal and Hewage 2013;Madeira Filho 2017), contractual inadequacies (Porwal and Hewage 2013;Madeira Filho 2017), unclear roles and responsibilities with the advent of BIM (Porwal and Hewage 2013), incorrect usage of BIM tools (Madeira Filho 2017) and imperfect data file with the potential to contain errors, omissions, conflicts, inconsistencies and other inaccuracies (Madeira Filho 2017). The report from McGraw Hill Construction (2014) shows that BIM return of investment increases directly with a contractor's level of BIM engagement, represented by its BIM experience, skill level and commitment to doing a high percentage of its work in BIM.…”
