Some BIM implementation strategies are critical, while others are insignificant and ineffective in terms of lowering BIM adoption obstacles and promoting widespread acceptance of BIM in projects. The BIM literature has not provided evidence to support this claim or identify the fundamental BIM implementation strategies. This study filled this gap by identifying and investigating the effect of fundamental BIM implementation methodologies on the occurrence of proportional impacts between stages.

The findings indicate a positive and crucial relationship between the stages of the BIM implementation strategies and the reduction of barriers (r = 1.79, z = 2.15), preliminary and sustained BIM adoption barriers (r = 1.53, z = 60.83), BIM adoption on projects and BIM-enabled integration and collaboration (r = 0.7, z = 2.74). This validates the model's hypotheses and demonstrates that the fundamental BIM implementation strategies will accelerate the reduction of BIM adoption hurdles. The impact, however, will be the same for both sustained and preliminary barriers. This implies that lowering the obstacles alone will not secure BIM adoption.

The validation of the model's hypotheses demonstrated that the fundamental BIM implementation strategies will accelerate the reduction of BIM adoption hurdles. The impact, however, will be the same for both sustained and preliminary barriers. This implies that lowering BIM adoption obstacles alone will not secure BIM adoption. This study proposes that BIM deployment tactics be carefully chosen in order to remove preliminary impediments, reduce barriers and energise BIM acceptance.

In line with the findings of this study, BIM adoption must be consistent and long-term before the benefits in project execution become evident and substantiated. The BIM abilities of project participants, the feasibility of BIM conventions and the proficiency of BIM supervisors may all play a role in this.

This research implies a few approaches and tactics for implementing BIM in an efficient and beneficial manner. The study's findings imply that BIM deployment tactics should be carefully chosen in order to remove preliminary impediments, reduce barriers and energise BIM acceptance. It also explains how to structure BIM implementation strategies in developing countries. Another significant practical implication is the model's conclusion on the benefits of BIM adoption.

This study emphasises the significance of understanding the interrelatedness between the stages of the BIM implementation process in order to promote unavoidable and high-quality BIM adoption, as well as identifying the essential strategies that will guide policymakers and industry players in improving and pursuing successful BIM implementation. This study adds to BIM implementation theories by providing new information on the models, stages and interconnections of the BIM implementation process. However, the study could not identify the factors that impede BIM adoption despite the reduction in barriers and use of fundamental BIM implementation strategies.

Commercial building facility systems are costly, and due to the complexity of operation and maintenance (O&M), some failures can cause irreversible expensive damage. Currently, few capabilities of building information modeling (BIM) have been used in the facility maintenance operation. The purpose of this paper is to use a tool for making it easier to predict preventable defects in commercial building facility systems by examining a complete BIM.

To this end, a list of frequent defects in the facility system was achieved by a review of commercial building literature. Then, by examining a complete BIM model, the available methods and tools for O&M facilities during the operation period are identified and analyzed.

The results of the paper show that the solution presented based on total productive maintenance (TPM) subsets can effectively prevent facility system defects during the operation and maintenance period. An expert team assesses the validation of results.

The findings can help facility managers to adopt measures using TPM methods to prevent defects through an integrated BIM platform. The examination is based on case studies, surveys, expert experience and a thorough literature review.

This paper aims to comparatively examine the impact of the intellectual capital performance on the financial performance of Islamic and conventional banks in the Gulf Cooperation Council (GCC) countries by classifying intellectual capital as human capital, knowledge creation and innovation processes.

Along with the theoretical discussion in essentialising the rationale for intellectual capital formation through Islamic norms, the empirical analysis is formulated through the data generated by disclosure analysis using a panel of five GCC countries examining 408 annual reports from 19 Islamic and 23 conventional banks covering 2010–2019 period. In the analysis of the generated data, both fixed and random effects regression models are used.

The findings of this paper suggest that Islamic banks perform better than conventional banks in creating intellectual capital through knowledge creation, human capital and intellectual contribution. While the intellectual capital disclosure index and its pillars are significant for Islamic banks, these variables are not significant for the conventional banks in the GCC countries.

Considering that disclosed information may not reflect actual experience and performance, factual data could also be used to overcome potential shortcomings of disclosure generated data.

This paper demonstrates that Islamic banks in the GCC have been successful in their intellectual capital performance, whereby they seem to be performing in line with the Islamic ontology. In addition, the disclosure items used in this paper may guide the Islamic and conventional banks in the process of preparing their annual reports. Importantly, they may use these items as benchmarks in further developing their intellectual capital performance for better financial performance.

This paper essentialises knowledge development and innovation for Islamic banks through the Islamic cognitive system rather than as a requirement of the market mechanism. Secondly, a comparative analysis between Islamic and conventional banks is presented by acknowledging the peculiarities of Islamic banks in the methodology and disclosure index.

Digital media is reshaping architectural design by introducing new tools, methods and workflows. Among various AEC tools, Building Information Modeling (BIM) has gained popularity due to its collaboration platform enabling cross-disciplinary teamwork during whole life cycle of buildings. BIM has further transformed culture and processes associated with design, construction and operation of buildings, hence triggering new building regulations in developed countries. However, in developing countries, BIM implementation is facing several barriers, such as lack of investment in technology and training, hesitation in quitting traditional tools and practices, etc. The purpose of this paper is to highlight potentials of BIM for developing countries, which are in need of more sustainable policies for enhancing their economic and environmental performances.

Throughout the text, a literature review on BIM including its dimensions and benefits, impacts on architectural design and adoption in global and local contexts is provided. In case study, surveys and structured interviews are conducted with BIM user and non-BIM user architects throughout Pakistan. Beyond 2D/3D modeling, the use of BIM applications for sustainable design process such as scheduling (4D), cost estimation (5D), performance analysis and facilities management (6D) is investigated.

Using analytical tools of an online surveying tool and SPSS statistical software, barriers and motivations for BIM implementation in Pakistan are determined. Strategies for further BIM adoption and implementation via “education and training institutions” and “supporting organizations and institutions” are defined.

As a developing country, Pakistan shall be moving the barriers for the spread of BIM technology. Recent research covered the entire AEC sector (Masood et al., 2014; Sohu et al., 2017; Ali et al., 2018), yet this paper focuses specifically on architectural design and practice field. In order to find out experiences and expectations about BIM technology in the architecture sector, professionals are surveyed and four chief architects are interviewed. How far have Pakistani architects adopted BIM? For which project types and scales is BIM more serviceable for them? Which BIM applications are they implementing to overcome the limitations in their professional practice? In Pakistan, where sustainability, in terms of scheduling, cost estimation, performance analysis and facilities management, is an indispensible measure for local practices, has implementation of BIM technology achieved sustainability in architectural design process? What are the motivations of Pakistani architects for becoming BIM users in future?

This study aims to leverage the implementation of building information modelling (BIM) in facilities management (FM), and thus the integration of BIM and FM are explored. It looks at identifying the information needed to implement BIM application in FM, to determine the level of implementation of BIMFM as well as to recommend BIMFM application mapping for building life cycle.

This study applied qualitative methodology, upon which a purposive sampling to 16 interviewees were conducted among professionals involved in any BIM, FM, BIMFM projects. Final analysis was conducted using thematical analysis by ATLAS.ti software.

The types of information required to implement BIMFM range from managerial information, commercial information, technical information and all full life cycle data. The implementation of BIMFM is agreed as beneficial, as it builds up efficiency of building performance, able to close gap of loses information, helps to improve FM in terms of data management, mitigates the problems, identifies priority defects and to enhance the FM processes. Respondents also believed that the causes where there is no implementation of BIMFM is in the situations where things are in order and when it becomes very expensive.

This paper has managed to gather the essential elements toward leveraging the implementation of BIMFM in digital construction project which are in the means of information types, the needs of BIMFM implementation and towards the end drawing the BIMFM implementation plan framework that could be used as a reference for the practitioners and industry.
