The purpose of this paper is to develop a novel tool to support decision making for enhanced demolition process efficiency and material waste sortability through computerised 4D motion workflow simulation.

A time-lapse evaluation model was developed to classify and estimate the impact of building demolition processes and material waste recovery. The dynamic assessment of demolition, collision and mechanical impact was measured through computerised 4D motion game and physics engines. Waste recovery and treatment complemented the simulation algorithm. The simulation of the information workflow was tested through case study using two demolition strategies.

The simulation successfully estimated the efficiency and efficacy of the different demolition strategies. Thus, simulation results can potentially support better decision making related to the definition of demolition strategies associated with recycling and re-use targets.

The simulation was limited to a simple machine-led demolition strategy. Further research is required to understand the impact of complex machine mechanic movements and processes on complex building fabrics.

Modelling and evaluating the demolition process and its impact on material waste recovery with a time dimension is novel. The comparative analysis of quantitative data allows demolition professionals to find optimal and more sustainable demolition solutions and more efficient and safer implementation on site. It also contributes to a better understanding of the relationship between demolition strategy and waste sortability. This research represents a significant advancement in applied computing for building demolition waste recycling and notably, it improves the quality of information available in the definition of building demolition strategies.

The purpose of this study is to explore existing literature on Building Information Modelling (BIM) in Malaysia and examine the perception of practitioners about the potential of BIM applications in reducing construction waste and enhancing productivity.

First, using 244 bibliographic data extracted from the Scopus database, the paper used scientometric analysis and VOSviewer mapping technique to assess the most impactful publication literature on BIM in Malaysia to identify the existing research gaps. Second, using a structured questionnaire, a total of 100 questionnaires were distributed to practising practitioners who incorporate BIM in the delivery of their projects. Descriptive analysis using cross-tabulation in SPSS software, radar chart, relative importance index and Pearson’s correlation were used to analyze the data.

The research gaps are in the fields of construction projects, buildings, energy efficiency, lifecycle and housing. The findings of the survey indicate that quantity take-off, clash detection, site utilization planning, digital fabrication as well as 4D stimulation were the main BIM applications used among the practitioners in Johor and Selangor.

By assessing the state-of-the-art of BIM and BIM applications in this region, the practical implications of this study provide useful insights to construction stakeholders, funding organizations, policymakers, research institutions, professionals, journal editors, reviewers and researchers to understand the overall trend of BIM in Malaysia and its usage.

This paper is the first to use science mapping using scientometrics to reveal the current BIM research in “Malaysia only”. Relying on the identified gaps, the study further examined the usage of BIM applications in Malaysian construction projects.

The section of the research presented in this paper aims to review and explore health and safety (H&S) issues on construction sites. It has the sole intention of using better computer visualisation to meet the needs of site practitioners in understanding such H&S problems.

The methodology follows a traditional literature review approach to understand the development of building information modelling (BIM) technology up to its current status. A questionnaire survey was conducted to gather information on the embedding of H&S planning by site practitioners within the BIM environment.

BIM has the potential to be used in H&S planning procedures, particularly in those related to tasks on construction sites. A framework for an integrated visual tool is developed for better H&S practice on site. It may be used actively by all practitioners, starting with site induction and addresses, inter alia, personal hazard perception.

This paper provides a foundation for developing a tool that helps construction personnel explore potential H&S risks on site before construction begins. By introducing a framework for integrating BIM and project planning, a prototype can be developed to demonstrate the application of the proposed framework.

The research presented in this paper introduces BIM usage during the construction stage as a tool that supports a H&S toolbox. The paper proposes the useful framework for better H&S practice on site that can be used actively by all practitioners. The intention is to find a way forward in addressing “real” H&S site issues that may not be easily understood by practitioners without the full aid of visualisation scenarios.

Recent studies concerning future air transport systems propose an operational model based on contract‐based air transportation system concepts, which impose 4D (spatial and time) constraints, called target windows (TWs), at different parts of the flight plan that an aircraft has to respect. The paper's aim is to find the set of all possible approaches for controlling punctuality at destination without violating the constraints imposed by a given sequence of TWs.

By quantifying such factors as distance between neighbouring TWs, size and temporal location of TWs, as well as the duration for which each TW should be valid, the authors arrived at a methodology for calculating a feasible sequence of TWs specific and appropriate to each flight scenario. Using these they sought control interface designs that would provide better arrival times at flight path reference points while minimizing potential conflicts.

A “pinch‐and‐pull” interface capable of implementing a real‐time, arrival‐time delay‐minimization process, which aims to achieve punctuality at destination by dynamically imposing appropriate modifications on aircraft flight velocities as dictated by TW definitions, was created.

With novel improvements to current methods for controlling aircraft punctuality at destination as proposed in this paper, great strides in flight path manoeuvrability may result, provided the pace of data management and display can parallel such developments.

The unorthodox approach to optimizing punctuality involves novel development of TWs, so as to transitively reduce uncertainty throughout the 4D trajectory defining the journey, rather than just at terminals. As a means of dramatically enhancing information display, a highly efficient pinch‐and‐pull interface for visualising these TWs was also developed.

The construction industry is well known for its high accident rate and many practitioners consider a preventative approach to be the most important means of bringing about improvements. The purpose of this paper is to address previous research and the weaknesses of existing preventative approaches and then to describe and illustrate a new application involving the use of a multi‐dimensional simulation tool – Construction Virtual Prototyping (CVP).

A literature review was conducted to investigate previous studies of hazard identification and safety management and to develop the new approach. Due to weaknesses in current practice, the research study explored the use of computer simulation techniques to create virtual environments where users can explore and identify construction hazards. Specifically, virtual prototyping technology was deployed to develop typical construction scenarios in which unsafe or hazardous incidents occur. In a case study, the users' performance was evaluated based on their responses to incidents within the virtual environment and the effectiveness of the computer simulation system established though interviews with the safety project management team.

The opinions and suggestions provided by the interviewees led to the initial conclusion that the simulation tool was useful in assisting the safety management team's hazard identification process during the early design stage.

The paper introduces an innovative method to support the management team's reviews of construction site safety. The system utilises three‐dimensional modelling and four‐dimensional simulation of worker behaviour, a configuration that has previously not been employed in construction simulations. An illustration of the method's use is also provided, together with a consideration of its strengths and weaknesses.

The introduction of Building Information Model (BIM) tools over the last 20 years is resulting in radical changes in the architectural, engineering and construction industry. One of these changes concerns the use of virtual prototyping – an advanced technology integrating BIM with realistic graphical simulations. Construction virtual prototyping (CVP) has now been developed and implemented on ten real construction projects in Hong Kong in the past three years. The purpose of this paper is to report on a survey aimed at establishing the effects of adopting this new technology and obtaining recommendations for future development.

A questionnaire survey was conducted in 2007 of 28 key participants involved in four major Hong Kong construction projects – these projects being chosen because the CVP approach is used in more than one stage in each project. In addition, several interviews are conducted with the project manager, planning manager and project engineer of an individual project.

All the respondents and interviewees give a positive response to the CVP approach, with the most useful software functions considered to be those relating to visualisation and communication. The CVP approach is thought to improve the collaboration efficiency of the main contractor and sub‐contractors by approximately 30 percent, and with a concomitant 30 to 50 percent reduction in meeting time. The most important benefits of CPV in the construction planning stage are the improved accuracy of process planning and shorter planning times, while improved fieldwork instruction and reducing rework occur in the construction implementation stage. Although project teams are hesitant to attribute the use of CVP directly to any specific time savings, it is also acknowledged that the workload of project planners is decreased. Suggestions for further development of the approach include incorporation of automatic scheduling and advanced assembly study.

Whilst the research, development and implementation of CVP is relatively new in the construction industry, it is clear from the applications and feedback to date that the approach provides considerable added value to the organisation and management of construction projects.

The main purpose of this study is to reveal the degree of association between lean, building information modeling (BIM) and construction project success. The study further intends to provide strategies for high and low associations of the factors.

Lean construction and BIM are two important applications that have recently gained popularity in terms of enhancing project success. Considering this impact, this study investigates the synergy between lean construction and BIM and determines to what extent these two contribute to the success of the projects. As a first step, lean, BIM and project success were examined based on an in-depth literature review. In the second stage, a structural equation model (SEM) was established to reflect the relationship among these three through hypotheses. Then, a questionnaire was designed and administered to the construction professionals experienced in both lean and BIM implementation. The SEM was tested using Analysis of Moment Structures (AMOS), an SPSS tool.

The results indicated that lean implementation has a significant and positive impact on BIM implementation and project success. On the other hand, BIM implementation had a lower significant impact on project success than lean implementation construct.

The results of this study can be used by both policymakers and industry practitioners in terms of developing strategies for effectively using both lean and BIM. The researchers can further develop other implementation models to investigate whether these concepts are more effective in increasing project success when used integratively.

This study considers both the impact of lean and BIM on project success through input from construction practitioners working on large projects. This way, the study fosters the use of lean, BIM or lean–BIM together in construction projects to enhance project success.

The purpose of this paper is to investigate the potential integration of deep learning (DL) and digital twins (DT), referred to as (DDT), to facilitate Construction 4.0 through an exploratory analysis.

A mixed approach involving qualitative and quantitative analysis was applied to collect data from global industry experts via interviews, focus groups and a questionnaire survey, with an emphasis on the practicality and interoperability of DDT with decision-support capabilities for process optimization.

Based on the analysis of results, a conceptual model of the framework has been developed. The research findings validate that DL integrated DT model facilitating Construction 4.0 will incorporate cognitive abilities to detect complex and unpredictable actions and reasoning about dynamic process optimization strategies to support decision-making.

The DL integrated DT model will establish an interoperable functionality and develop typologies of models described for autonomous real-time interpretation and decision-making support of complex building systems development based on cognitive capabilities of DT.

The research explores how the technologies work collaboratively to integrate data from different environments in real-time through the interplay of the optimization and simulation during planning and construction. The framework model is a step for the next level of DT involving process automation and control towards Construction 4.0 to be implemented for different phases of the project lifecycle (design–planning–construction).

The oil and gas industry form the main resource of economy in Iraq and constructing any project in such sectors requires a huge amount of expenses due to the unique requirements that oil and gas facilities required in such projects. Therefore, adopting an appropriate technological approach such as building information modeling (BIM) which is unfortunately not adopted yet in Iraq is essential to successfully deliver these projects. Thus, this paper aimed to introduce BIM to Iraq through Basra Oil Company (BOC) which is one of the biggest public oil and gas companies in Iraq.

The related literature of journals articles, conference proceedings and published reports have been reviewed. As a result, firstly: a hypothesis has been derived that is “If Basra Oil Company (BOC) adopts and applies BIM approach instead of the 2D approach currently used to manage its projects, the company can overcome several constraints in managing its projects that associated with such 2D traditional approach”; secondly: homogenous, consistence and reliable web-based questionnaire has been designed as its Cronbach’s alpha equal to 0.897 and 0.711 for BIM benefits and barriers, respectively. This questionnaire distributed to the BOC related professionals to test such hypothesis by investigating their readiness and accepting of BIM approach and to rank BIM barriers based on five-point Likert scale.

Based on the analysis using IBM SPSS Statistics 26 of 115 responses, almost 50% of the respondents had experience 11–15 years, while 22.6% had experience more than 15 years in oil and gas industry construction projects. Those participants were from diverse engineering majors that are: 4.3% Architectural Engineers, 31.3% Civil Engineers, 20% Mechanical Engineers, 22.6% Electrical Engineers and 21.7% from other engineering majors. The respondents’ departments demography was 16.5% of design department, 12.2% of construction department, 20.9% of Project Management Department, 12.2% of Maintenance department, 4.3% of HSE Department, 13% of Production Department and 20.9% of “Other Department.” The study resulted in 1: accepting BIM approach to be an alternative of current 2D-traditional approach used by the company to manage and construct its projects, since mean of collected data is (4.4332), Kruskal–Wallis H test significance values were 0.398 and 0.372; and ANOVA test significance values were 0.433 and 0.599 among Engineering Majors groups and Company’s Department groups, respectively. 2: Disclosed and sequenced BIM barriers in the company based on their criticality. 3: verifying reliably how BIM attributes are important to oil and gas construction projects in Iraq, 4: the company top management and company policies are the most critical potential factors to hinder or adopt and implement BIM in the company, 5: while cost is not seen a critical barrier to implement BIM in the oil and gas sector.

The limitation of this study is the excluding of decision makers of BOC, thus more profound future studies need to be conducted where top management and decision makers are involved, particularly the present study demonstrated that support of company top management is the most critical factor which can help the company to adopt (BIM).

The study concludes that BIM approach is valuable for managing projects in oil and gas sector in Iraq and identify the originality in output by using the research method. This noble study provides a leverage for enhanced research to adopt and implement building information modeling (BIM) in Iraq as the study originally demonstrates benefits and identifies the critical barriers in BIM implementation to push the boundaries toward adopt Digitalization and reduce CO2 emission in Iraqi oil and gas sector. The study can be used as evidence and platform to encourage professionals and practitioners to present more sophisticated tools of BIM in the oil and gas industry, especially for facility and operation management. These findings achieved via oil and gas experts, and it is first time to achieve such findings from a case study in Iraqi oil and gas sector.

The purpose of this paper is to investigate the barriers that are constituting significant obstructions to preliminary and sustained BIM adoption in the South African construction industry.

Implementation Process Theory was used to develop the theoretical model of barriers to continuous and consistent BIM adoption. This enabled the formulation of two hypotheses, the identification of two sub-constructs (barriers to preliminary BIM adoption and barriers to sustained BIM adoption), and five variables (resources, knowledge, work process, organisational and planning barriers), which were validated using structural equation modelling (SEM).

The SEM results show pieces of evidence that validate the hypotheses in the theoretical model. The path analysis confirms that the two sub-constructs and five variables are statistically significant.

This research extends the postulations on the barriers to BIM adoption by demonstrating that organisational challenges and planning difficulties constitute barriers to sustained BIM adoption in the South African construction industry.

The findings of this research are useful in understanding the planning scope and organisational requirements towards continuous and consistent BIM adoption in the South African construction industry.

The difficulties with BIM adoption are the issues with the performance of BIM on projects and are the major reason for the non-consistent adoption of BIM on projects. Having difficulties adopting BIM on projects suggests that BIM adoption is majorly on a preliminary or trial basis in the developing countries. This research tests this theory by proposing two types of BIM adoption and their associated barriers.
