There are no clear-cut thresholds to classify the BIM implementation-centred efforts in the construction industry. This research seeks to remedy this problem by identifying the reduction indicators ...for tracking BIM adoption barriers and providing evidence of the indicators in South Africa. A model of BIM implementation thresholds was developed highlighting industry-level indicators (ILI), organisation level indicators (OLI), and project-level indicators (PLI). A quantitative research design was employed where data were collected through e-mail invitations and web links from a total of 975 purposively selected BIM supply chain members. Three hypotheses were postulated from the model and tested using Structural Equation Modelling (SEM). The SEM result validates the hypothesis which theorises that the indicators of a reduction in BIM adoption barriers are more noticeable at the organisation level. The results revealed that BIM adoption barriers, such as lack of BIM resources, and non-readiness of employees to accept changes, have been significantly reduced. It was concluded in this research that the South African construction industry is a BIM-frontier construction industry with noticeable indicators at the organisation level. The findings and conclusions of this research are geographically limited because the data were collected and analysed in the South African context. An important issue for future research is the investigation of essential BIM implementation strategies for the different levels in the BIM implementation thresholds.
Purpose
This study aims to undertake a contextual analysis of project-level building information modelling (BIM) adoption in Nigeria and demonstrate how BIM is applied across different projects in ...Nigeria.
Design/methodology/approach
This research generates contextual and holistic understandings of multiple project-level cases of BIM adoption through an interpretive paradigm guided by relativist ontology and subjectivist epistemology. Two models of project-level BIM adoption (ten-factor theory of BIM adoption and strategic-contingent model of BIM adoption) were merged to formulate the BIM adoption assessment scale (BIM-AAS). A qualitative-oriented case study protocol was developed to extract valid and reliable data from external and internal project data based on BIM-AAS features. The extracted data were analysed using the pattern-matching technique and cross-case analysis.
Findings
The results indicate that there was substantial use of BIM tools and technologies in the projects. All the projects adopted collaborative procurement and team and developed integrated building information models. The use of BIM tools, technologies and processes in the projects was found to be above average. The complexities and expectations levels of the projects compliment the nature of BIM adoption in the projects.
Research limitations/implications
The BIM-AAS adopted in this research is an excellent example of a project-level BIM adoption analytical tool. It can be assumed in future research. Also, this research contributes to the theory that the level of project complexity and expectations must align with the level of BIM adoption in projects. The study’s findings ratify BIM tools, technologies and processes as the elements of project-level BIM adoption.
Practical implications
This research substantiates the actual nature and structure of BIM adoption in Nigeria, thereby simplifying the development of initiatives towards BIM adoption in projects and determining the appropriate strategies for BIM implementation and innovation in the Nigerian construction industry. The most important initiative that the Nigerian government can make to drive BIM implementation is the automating of code checking for building rules and regulations in Nigeria.
Originality/value
Previous studies have only reported cases of project-level BIM adoption using surveys and without a standardised project-level BIM adoption model to guide the analysis. This study is the first to formulate and use BIM adoption models for a uniform, critical and contextual analysis of project-level BIM adoption.
Building Information Modelling (BIM) implementation is considered a daunting reality because majority of the construction players don’t know the potential benefits of the technology. Awareness of BIM ...benefits and its implementation could significantly increase project productivity and performance. This study is aimed to determine the influence of BIM benefits from the Malaysian construction stakeholders’ perception towards its implementation. The study was carried out using survey questionnaire. Out of 590 questionnaires 268 were collected that represent a sample size of 346. Results revealed that most of the construction companies lack of awareness about BIM technology. The statistical analysis showed that productivity, time, cost, clashes, and communication are the most essential BIM benefits that concerned the participants. The driving factors of implementation, on the other hand, were identified as Trust, respect, commitment, early involvement, and knowledge. It is also found that there is a significant relationship between BIM benefits and its implementation.
Building Information Modelling is one of the crucial topics in the construction industry. The construction industry has played an important role to assist stakeholders to successfully transfer ...construction practices to BIM-based technology. Currently, no systematic research that has been carried out to determine the level of BIM implementation in Malaysia. Therefore, this paper aims to evaluate the diffusion of BIM among Malaysian companies. The results of the 268 responses received revealed that only 13% of the participants from both public and private sectors are using BIM in their organization and this is a negative sign that Malaysia is still far away from the position it supposed to be in BIM implementation. Lack of awareness, costs, slow adaptation, unavailability of a clear guideline to assist organizations and policymakers toward BIM implementation transforming and that BIM was not mandated in sufficient time were observed to be responsible for the slow implementation.
In recent years, the progress of digitization in the architecture and construction sectors has produced enormous advances in the automation of analysis and evaluation processes. This is the case with ...environmental analysis systems, such as the life cycle analysis. Methodology practitioners have found a fundamental ally in the building information modeling platforms, which allow tasks that conventionally consume large amounts of energy and time to be carried out more automatically and efficiently. In this publication, the reader will find some of the latest advances in this area.

Building Information Modelling (BIM) concepts and workflows continue to proliferate within organisations, through project teams, and across the whole construction industry. However, both BIM ...implementation and BIM diffusion are yet to be reliably assessed at market scale. Insufficient research has been conducted to date towards identifying the conceptual structures that would explain and encourage large-scale BIM adoption. This paper introduces a number of macro-adoption models, matrices and charts (Fig. 1). These models can be used to systematically assess BIM adoption across markets, and inform the structured development of country-specific BIM adoption policies.
This research is published in two complementary papers combining conceptual structures with data collected from experts across a number of countries. The first paper “Macro-BIM adoption: conceptual structures” delimits the terms used, reviews applicable diffusion models, and clarifies the research methodology. It then introduces five new conceptual constructs for assessing macro-BIM adoption and informing the development of market-scale BIM diffusion policies. The second paper “Macro-BIM adoption: comparative market analysis” employs these concepts and tools to evaluate BIM adoption and analyse BIM diffusion policies across a number of countries. Using online questionnaires and structured interviews, it applies the models, refines the conceptual tools and develops additional assessment metrics. The two papers are complementary and primarily intended to assist policy makers and domain researchers to analyse, develop and improve BIM diffusion policies.
•BIM implementation and BIM diffusion concepts are overlayed into BIM adoption.•Point of Adoption model combines and compares readiness, capability and maturity.•Conceptual Reactor model uses existing conceptual structures to generate new ones.•Five macro-adoption models, their companion matrices and charts are introduced.•The scene is set for a new discussion covering market-wide BIM diffusion policies.
This study investigates the applicability of a success level assessment model for building information modeling (BIM) projects (SLAM BIM). SLAM BIM is a goal-driven method for the sustainable ...evaluation of a BIM project's success. It was developed on the premise that a project's success cannot be evaluated without first identifying its goals; thus, key performance indicators (KPIs) can vary according to project goal. SLAM BIM consists of five steps for defining BIM goals, uses, KPIs, unit measurements, and data collection forms and processes. To identify appropriate BIM KPIs, the collectability, measurability, and comparability of the candidate BIM KPIs were considered. Data related to schedule, design errors, change orders, response time, and ROI were collected and analyzed in the two projects by using the SLAM BIM process. The validity of SLAM BIM was tested by applying SLAM BIM from the beginning to the end of two construction projects.
•This study suggests a success level assessment model for BIM projects (SLAM BIM).•SLAM BIM is a goal-driven method for sustainably evaluating BIM project success.•It defines BIM goals, uses, KPIs, unit measurements, and collection forms in step.•SLAM BIM is tested to two construction projects in South Korea.

With increasing complexity of construction projects, a collaborative environment becomes essential to ensure effective communication during the project lifecycle. Conventional team collaboration ...raises issues such as the lack of trust; uncertainties regarding ownership and Intellectual Property Rights (IPRs); miscommunication; and cultural differences, among others. Additional issues can arise in relation to the generated data, including data loss, data inconsistency, errors, and liability for wrong or incomplete data. Furthermore, There is a shortage of studies that investigate collaboration practices, data management, and governance issues from a socio-technical perspective. This study investigates the development of a BIM governance framework (G-BIM) with support of Cloud technologies, identifying effectiveness factors that guarantee successful collaboration. Semi-structured interviews were conducted with informed BIM experts in the UK, with the aim of: (i) discovering current trends in Information Communication Technologies (ICT) and team collaboration during construction projects; (ii) exploring barriers to BIM adoption; (iii) exploring the role of BIM-related standards; (iv) consulting BIM experts to develop a Cloud-based BIM governance solution to tackle team collaboration on BIM-based projects; and (v) investigating the role of Cloud in supporting BIM governance research and development. The findings reveal several BIM adoption barriers and issues directly influencing team collaboration. The key findings led to the development of a BIM governance framework (G-BIM). The purpose of the G-BIM framework is to present and summarise effective factors resulting in successful governance and a collaborative BIM approach, to support the future development of a Cloud-based BIM governance platform. The G-BIM framework comprises three main components: (i) actors and team, (ii) data management and ICT, and (iii) processes and contracts. Furthermore, the study reveals the high potential of Cloud technologies to advance current BIM governance solutions, because of its performance capabilities, accessibility, storage, and scalability.

Automatic comparison of time-variant BIM models facilitates value-added applications during the building life cycle. This paper addresses a solution capable of exploring changes between point clouds ...and BIMs (Scan-vs-BIM) or between time-variant BIMs (BIM-vs-BIM). To this end, a change component identification (CCI) algorithm is proposed to determine changing states, spatial locations, and semantic information of the change components. In that, CCI realizes an object-oriented strategy and enables exploration of the local geometry of object shape and comparison of object similarity without being limited to specific targets. Validations demonstrate the effectiveness of CCI, which achieves an accuracy of up to 93% and 80% in the BIM-vs-BIM and Scan-vs-BIM cases, respectively. The proposed method is expected to improve the automation level to document construction progress or confirm discrepancies between as-is and as-built BIMs.
•An object-oriented algorithm of CCI is proposed to realize BIM-vs-BIM and Scan-vs-BIM change detection.•The CCI provides five changing states, locations, and semantic information of change components.•The categories of change components in CCI can be specified based on the requirements of practical missions.•The CCI improves the automation of time-variant change detection of BIM, promoting BIM-based applications.
Despite the vast success of the United Arab Emirates (UAE) in developing residential, commercial facilities and infrastructure; the track record of the country's Architecture, Engineering, and ...Construction (AEC) industry is somewhat different with overwhelming evidence of poor performance. Albeit the promising nature of the UAE's AEC industry, that sought to embrace the latest technologies, the research revealed that, BIM is not yet widely utilised. The UAE was selected as a case study due to the diversity of its local AEC industry, whereby the AEC market has attracted contractors, consultants, suppliers from across the globe. This research adopted a mixed methodological approach using both quantitative and qualitative data collection methods to gather data from BIM users and non-users. The research investigated the perceived benefits and challenges of adopting BIM and the impact of short and long-term initiatives that can be deployed to drive the effective diffusion of BIM. The study found that there is irrefutable evidence of a lack of impetus to generate interest in BIM from an industry that has in fact undermined the pace of BIM adoption. This paper offers a set of practical recommendations not only for the government to accelerate the transition to BIM, but also to BIM late adopters.
