BIM-based approach to manage Basra Oil Company projects

PurposeThe 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.Design/methodology/approachThe 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.FindingsBased 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.Research limitations/implicationsThe 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).Originality/valueThe 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.

A Holonic Construction Management System for the Efficient Implementation of Building Energy Renovation Actions

In the architecture, engineering and construction (AEC) industry, many efforts have provided remarkable contributions to construction planning and control processes during work execution. Nevertheless, frequent coordination issues among stakeholders and difficulties in dealing with unexpected events can be explained by the complexity featuring the construction sector. Several approaches to deal with this issue were investigated in the manufacturing area, among which this paper looks at the holonic approach as one of the most promising strategies. This study first analyzes the more fragmented and dynamic nature of the construction industry as compared with the manufacturing one. Secondly, it suggests developing a process-based holonic construction management system based on building information modeling (BIM) and a conceptual architecture for manufacturing control called Product Resource Order Staff Architecture (PROSA). The process-based paradigm ensures exploiting the benefits of BIM towards the development of sustainable and efficient regeneration methods of the built environment. Subsequently, a first management system prototype was developed and tested for the purpose of renovation works management. For the first time, results from an actual implementation of PROSA were applied to a real construction site, and its feasibility was assessed using the data on the field. Key performance indicators (KPIs) evaluated during the onsite demonstration confirmed a good performance of PROSA and the presented holonic approach, which contributed to the overall success of the energy efficient refurbishment project.

EXPLORING 4D AND 5D ANALYSIS IN BIM ENVIRONMENT FOR INFRASTRUCTURES: A CASE STUDY

Abstract. Building Information Modelling (BIM) has emerged as a focal point in the construction industry, garnering substantial attention due to its capacity to elevate product quality, facilitate accurate quantity determination, and enhance scheduling efficiency. The inherent complexity of construction projects necessitates the integration of BIM models endowed with automation functionalities for schedules and cost estimation. This integration ensures that updates seamlessly occur throughout the construction process, thereby mitigating project uncertainties and reducing overall costs. While the potential benefits of BIM are recognized, a substantial challenge persists in the Architecture, Engineering, and Construction (AEC) field defining workflows for the automated generation of optimized 4D/5D BIM simulation and analysis. The effective utilization of BIM as a transformative tool requires addressing this challenge to unlock its full potential in project management. BIM serves as a pivotal conduit for project data, providing a structured approach to elevate overall product quality, streamline processes, and minimize contingencies and costs associated with construction projects. Consequently, the successful implementation of BIM with automated 4D/5D simulation and analysis stands as a critical milestone in advancing the capabilities of the AEC industry, ensuring greater efficiency, accuracy, and cost-effectiveness in construction projects. According to these aspects, the time-cost analysis (4D/5D) of a project for the North-South railway station in Riyadh, designed by Architect Engineer Dia Hilal, was investigated.

Construction management students’ perception of BIM adoption and its implications in a non-mandated country

Building information modeling (BIM) is increasingly being recognized and gradually adopted by the construction industry in India, even though it is still not mandated by the Government. As the demand for trained BIM professionals grows, many educational institutes in India have started including BIM in their respective architecture, engineering, and construction (AEC) related curriculum courses, mostly at a beginner level. This study tries to access the perceptions of these AEC students towards various aspects related to the BIM practice and its adoption in India. It aims to provide a reference point, and help bridge the gap between the industrial BIM proficiency requirements, and the institutional BIM teaching-learning approach. As students are the prospective BIM professionals, this study gives important insights for the BIM practice stakeholders to understand the learners’ individual motivation, bias and experience. The methodology consisted of conducting an online questionnaire survey to collect the students’ demography and background data; as well as their perceptions (on a five-point Likert scale) towards BIM benefits, BIM functionalities, BIM as a career option, and challenges to BIM implementation in India. The 188 responses were divided into subgroups and statistically compared based on two-sample t-test and analysis of variance (ANOVA). Findings are discussed with their possible implications in the academia as well as the industry. The study emphasizes having a better engagement of the academia with the BIM industry and policy makers to develop a synergic BIM learning ecosystem.

Integrating BIM-LCA to Enhance Sustainability Assessments of Constructions

The need for sustainable practices in the construction sector has never been more pressing, as the sector seeks to mitigate its carbon footprint, water consumption, and waste generation. The integration of building information modeling (BIM) and life-cycle assessment (LCA) emerges as a promising solution for rapidly and accurately evaluating the environmental impact of construction. This integration has the potential to empower stakeholders to make informed decisions, paving the way for a more environmentally conscious future in the construction sector. However, there are still challenges to overcome before this is a standard procedure. Data interoperability and standardized classifications necessitate ongoing research. To understand the potential of BIM–LCA integration in minimizing carbon emissions in constructions, this study focuses on a hypothetical renovation project, unraveling the mechanics of BIM–LCA integration and exploring its challenges and opportunities. While the existing literature acknowledges the potential benefits of BIM–LCA integration, few research efforts delve into the specific issues that practitioners may face. Our approach seeks to fill this gap by presenting a holistic view of the integration process, highlighting the practical steps and addressing the intricacies involved. The results show that the most relevant information when performing a BIM–LCA integration using Revit® (v 2022) and OneClick LCA (OCL) is the name-property given to the materials within Revit®. Despite the advances made by this semi-automated approach, interoperability and data accessibility challenges remain. The results show that automated material identification relies on Revit® classifications and necessitates careful modeling practices to prevent impact-calculation redundancy.

A Conceptual Framework for BIM-Based Site Safety Practice

With developments in Industry 4.0, there is growing momentum to adopt technology-assisted tools to support existing processes. Even though most construction processes are now computerized, safety procedures have not yet fully embraced the digital revolution. Building information modeling (BIM) is a platform that radically redefines the way in which businesses operate. Various past studies on the application of BIM in site safety mainly focus on using BIM for safety during construction and for a specific project type. The potential benefits of BIM for site safety have not yet been fully explored. The aim of the present study is to develop a BIM-based automatic safety checking (ASC) framework for an early identification of hazards. It includes safety checking with codified OSHA rules, corrective actions, scheduling, and reporting in a virtual environment. All these steps are part of the risk lifecycle which is typically managed according to the phases of construction on a physical site. However, in the proposed framework, all these steps are managed at the preconstruction stage in a virtual environment. The major contribution of this study is the proposed framework that provides the conceptual foundation for early site safety management by identifying hazards at the design stage. The integration of a 3D model with codified OSHA standard safety rules ensures that the design is in adherence to safety rules and is rendered hazard-free for a pilot case.

Challenges of BIM Software Implementation in Quantity Surveying Consultancy Firms: The Difference Between Large Firms and Small-and-Medium Enterprises (SMEs)

Inefficiencies and ineffectiveness in delivering construction projects had negatively impacted the industry for decades. However, the emergence of building information modeling (BIM) technology had influenced the construction process with its many benefits toward project success. BIM benefits included reduced project time and cost, improved team collaboration and communication, and improved project quality and performance. Consequently, BIM applications were claimed to provide more reliable working practices for quantity surveyors (QS), especially in establishing their cost estimates. Despite the well-known benefits that spurred BIM employment around the world, the usage of BIM software in Malaysia was still in its infancy, requiring greater deployment by the QS. Furthermore, the literature was scarce in comparing the use of BIM software by large organizations and Small-and-Medium Enterprises (SMEs). As a result, the primary goal of this study was to identify the numerous challenges associated with the adoption of BIM software in both large and SME quantity surveying consultancy firms. Apart from that, this paper identified the availability of BIM software in the construction sector as well as the use of BIM software in those consultancy businesses. A quantitative technique was used, with 393 questionnaire survey forms issued to Malaysian QUANTITY SURVEYING consultant businesses. The data was then analyzed using the Statistical Package for the Social Sciences (SPSS) to generate a reliable and valid result. According to the findings, Cubicost software was the most popular software used by QS specialists. Notably, the results revealed that SMEs face greater challenges than large organizations, particularly those connected to professional help, finance, and time, as well as technical issues. Because large corporations and SMEs differed in nature, this study could provide new insights to policymakers in aiding companies of various sizes in their BIM transformation process. The findings called for more policymakers to work together to improve practitioners' understanding of BIM-based technology. The difficulties of SMEs must be recognized, and policymakers must bridge the gap between large and SMEs to bring Malaysia's construction industry one step closer to a new era of digitalization.

Exploring BIM Implementation Challenges in Complex Renovation Projects: A Case Study of UBC’s BRDF Expansion

Renovation of existing buildings pose unique challenges to the projects, especially when facilities must remain operational during construction. Building Information Modeling (BIM) methods offer a potential solution by enhancing project management and coordination. Nevertheless, comprehensive case study research on BIM implementation challenges and benefits in renovation projects is lacking. This research addresses this gap through an ethnographic investigation of BIM implementation in a complex renovation project. The ethnographic methods involved direct observation of project meetings, active engagement in all project communications, and access to project data resources. Additionally, surveys and expert interviews with key decision-makers were conducted. The findings reveal how BIM implementation streamlined project management and improved communication, decision making, and output quality, despite limited prior BIM expertise among the major stakeholders. Challenges included a lack of BIM skills, absence of standardized practices, and unclear data management. Furthermore, valuable lessons were identified, including that the necessity of BIM requirements and proper procurement methods encompassing the entire project workflow, formalizing information exchange, preventing information fragmentation, facilitating model accessibility, and ensuring clarity in model detail and content are crucial for project success. This research sheds light on the potential of BIM in renovation projects and highlights key considerations for successful implementation.

SLOW ADOPTION OF BUILDING INFORMATION MODELING: COMPARING VIEWPOINTS OF DESIGNERS AND CONTRACTORS

The slow adoption of Building Information Modeling (BIM) technology poses significant problems for the construction industry in the Middle East. The root causes of this issue are purported to include a lack of understanding of its benefits and the existence of barriers to its adoption. This study investigates the slow adoption of BIM technology in the Middle East to identify solutions to facilitate BIM adoption and approaches by which stakeholders can transform to utilizing BIM. The main objectives of this research are to: (1) examine the attitudes and readiness of construction stakeholders for BIM, (2) investigate the extent to which there is a lack of understanding of BIM benefits, (3) explore the barriers that hinder BIM adoption, and (4) identify the solutions recommended by the industry experts to promote BIM utilization. The study also compares the viewpoints of designers and contractors to identify potential differences. A questionnaire survey has been devised to gather data from stakeholder firms and experienced BIM professionals. The results revealed that the viewpoints of designers and contractors generally align, except when it comes to recognizing a few benefits such as the generation of accurate and consistent 2D drawings, achieving greater predictability in project time, enhancing communication among project stakeholders, minimizing change orders, and mitigating redesign issues. Similarly, there was a difference in recognizing a few barriers, namely, the lack of skilled personnel and the cost of training existing staff. Furthermore, the analysis led to the conclusion that the most notable advantage of BIM is improved conflict detection, and the most significant barrier is the lack of BIM training. The research culminated in offering recommendations for addressing the industry's BIM-related challenges. These suggestions encompassed raising awareness of BIM as a robust design and construction tool, supporting construction firms for adopting BIM techniques, and identifying methods to streamline the implementation process within these firms.

Measuring the Benefits of Building Information Modeling (BIM) Adoption: Trends, Gapsand Future Directions

Building information modelling (BIM) adopters require well-documented, quantitative, and financial simulation studies as solid evidence for the benefits of BIM to implement it and evaluate its success.However, to move towards more practical analyses to be performed by the end-users, more discussions on process to measure BIM benefit should be held, despite the large number of studies related to BIM benefit indicators. Therefore, this study examines the proposed and simulated methods used to measure the benefits of BIM in previous studies. A systematic literature review (SLR) of 21 articles was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and analysed using meta-ethnography and thematic qualitative analysis. The SLR depicted the trends of studies published over the years. The results indicate that out of the 31 BIM benefits identified, only 17 BIM benefits have been measured in simulations.4 other BIM benefits were suggested to be explored in line with their magnitude of importance.Comparative case studies were used conventionally to collect the data for measuring these benefits. This has since shifted to conducting case studies of single BIM projects along with supplementary data collection for counterfactual assessment. Furthermore, predictive ex-ante studies are currently blooming. At present, ongoing studies are being conducted to demonstrate thedetailed technique with which to calculate and measure the benefits of BIM.This paper providesresearchers and analysts with initial insights that can be used to move forward with BIM benefit measurements.

Yet, the need for innovative ideas has presented the AEC sector with its fair share of hurdles. Introducing Building Information Modeling (BIM), a rapidly expanding tool on the global stage, aimed at boosting AEC efficiency and resolving key challenges. Recent times have witnessed both public and private sectors making BIM integration a requirement in new construction projects. However, the utilization of BIM by governments, particularly in less developed nations, remains limited. This research brings together industry stakeholders to discuss the merits of BIM, identify obstacles, and suggest practical solutions, thus encouraging wider adoption and reaping the benefits of BIM.

Potential for synergetic integration of Building Information Modelling, Blockchain and Supply Chain Management in construction industry

Construction industry nowadays is facing several key issues as the likes of cost and time overruns and unstable business environment which lead to suppressed profitability, quality, and stakeholder satisfaction. Studies have suggested, an improved Supply Chain Management (SCM) towards Sustainable Supply Chain (SSCM) could help in this regard, however there are barriers observed to its implementation in the construction industry. Building Information Modelling (BIM) too is considered a positive disrupter in the construction industry due to the potential in its applications, and one of such potential is improving the SCM. However, similar to SCM, adoption of BIM faces several barriers. Preliminary review suggests that some of its barriers could be resolved by integrating with Blockchain, another disruptor stemming from Industry 4.0. Hence, this paper attempts to assess how the synergy of BIM and blockchain would improve the SCM of the construction industry. For that purpose, through a systematic literature review, the paper structures the barriers of SCM, and barriers and benefits of BIM and blockchain in construction industry across the dimensions of Socio-technical, Industrial, Organizational, Financial, Legal and Institutional, and Sustainability, and conceptually maps the barriers and benefits to identify their collective impact on SCM. From this study it was found that with the help of Blockchain integration, there are a number of potential synergies that may solve critical inherent issues in both BIM and SCM, such as reluctance of information sharing and trust, sustainability concerns and safety, leading to positive cumulative impact on SCM. However, it was also recognized that there can be negative as well as neutral cumulative impacts on areas such as cost, and lack of personnel, knowledge and institutional support that can lead to an opposite impact.

Measuring the Benefits and Barriers of the Implementation of BIM in Sustainable Practice in the Construction Industry of Saudi Arabia

The construction industry of Saudi Arabia has witnessed notable innovation in sustainable practices in the form of building information modeling (BIM). Previously, a few studies dealt with either the benefits and barriers of BIM or sustainability. However, there is a limitation in these studies in terms of finding out the benefits and barriers of BIM in sustainable construction projects, especially in the context of Saudi Arabia. Therefore, the present study aimed to examine the determinants that impact the adoption of BIM in the construction industry of Saudi Arabia. A thorough examination of the existing literature was conducted in order to identify the various factors that contribute to the benefits and barriers of BIM. The research employed a questionnaire survey of 152 building engineering professionals from Saudi Arabia. The questionnaire’s results emphasize the key factors that are essential for the implementation of sustainable BIM. Initially, barriers and benefits were prioritized according to the relative importance index (RII). In addition, the study utilized statistical methods to identify the top five barriers that were deemed most significant. The Cronbach alpha test confirmed the presence of a statistically significant level of consistency in the responses provided by stakeholders. Moreover, the Spearman correlation test demonstrated that there was no statistically significant variance among the groups in their responses. The results indicated that among the 28 benefit factors, “improving design efficiency (RII = 0.788)”, “encouraging the use of energy-efficient clean technology (RII = 0.786)”, and “promoting green building design, construction, and management” were the top three benefits from BIM implementation in sustainable construction projects. On the other hand, “recurring demand for increased resources, together with high costs (RII = 0.720)”, “absence of a well-defined method for exchanging operational management data (RII = 0.713)”, and “lack of skilled personnel (RII = 0.708)” were the top five barriers to the incorporation of BIMs in the sustainable construction industry of Saudi Arabia. This study can provide valuable guidance for policymakers in developing countries who seek to successfully complete sustainable construction projects by encouraging factors that drive BIM implementation and enhancing project performance through the utilization of the benefits of BIM.

Machine learning multilayer perceptron method for building information modeling application in engineering performance prediction

ABSTRACT The engineering design process has fundamentally impacted the life cycle of construction projects and notably, the engineering performance is significantly measured in delivering projects. Previous studies on engineering performance have established the cause–effect relationships between project variables and performance measures. Recently, the building information modeling (BIM) application has reformed how owners execute the engineering, construction, commissioning, and operation in the industry. There has been an increasing focus in finding the benefits of BIM on project performance, however, a minor focus has been given to engineering performance. This paper proposes an artificial neural network (ANN) machine learning multilayer perceptron (MLMP) method and linear regression (LR) that correlates the use of BIM with engineering performance for better construction project assessment. The conclusions reveal a high-level correlation measure between BIM use inputs and engineering performance outputs and further methods for evaluating the engineering performance. Furthermore, we achieved and validated the best prediction by leveraging data from 60 samples using the MLMP and LR models.

Toward Improving BIM Acceptance in FM: A Conceptual Model Integrating TTF and TAM

Substantial research has been performed on Building Information Modeling (BIM) in various topics, for instance, the use and benefit of BIM in design, construction, sustainable environment building, and Facility assets over the past several years. Although there are various studies on these topics, Building Information Modeling (BIM) awareness through facilities management is still relatively poor. The researcher's interest is increased in BIM study is based heavily upon the perception that it can facilitate the exchange and reuse of information during various project phases. This property and others can be used in the Iraqi Construction industry to motivate the government to eliminate the change resistance to use innovations in the Iraqi construction industry. Even though many scholars and practitioners agree on the potential application and benefits of BIM in construction/ Facilities Management FM, it is yet unknown why BIM is used and what criteria facilitate BIM achievement in O&M. As long as the actual usage and acceptance of BIM in the Operation and Maintenance phase is still a central issue in practice, therefor depending on the extensive well ground literature review a conceptual acceptance model is proposed in this paper by applying the technology acceptance theories such as Technology Acceptance Model (TAM) and Task Technology Fit (TTF) to explore how the extent of facilities management staff going to accept and adopt the new international technology (BIM).

Determining Factors for Measuring the Benefits of Building Information Modelling (BIM)

Studies related to measuring the benefits of BIM become a new sensation. However, the reported values are highly inconsistent as there are no standards to benchmark the benefits according to different returning values. This paper presents a critical review of various factors that may affect the benefits to be measured from BIM. The review of previous studies aims to propose a novel classification approach for BIM benefits as a theoretical basis for further validation. The objective of this study is to explore BIM benefit returning factors. A total of 17 sources from peer-reviewed journals and various grey literature are included in the review with no time limit. From the underlying theories of Benefit Realisation Management (BRM) and the Benefit Identification Model, it is found that there are several factors that can be used to determine and classify the benefits of BIM for measurement purposes. An ontology of Benefit Determining Factor is proposed consisting of four (4) main dimensions, namely project context, stakeholder, time, and type using thematic analysis. The result is an attempt to make a theoretical breakthrough that introduces the existence of various BIM benefit influencing factors into the body of knowledge. These factors will provide researchers and analysts greater insight into more accurate measurement of BIM outcomes.

BIM Application in Construction Projects: Quantifying Intangible Benefits

Building information modelling (BIM) has been considered an effective and efficient tool among stakeholders of the construction sector as it delivers prominent results. Hence, this work aimed to determine the intangible benefits of BIM in construction projects. Various statistical analyses were performed to identify the most critical intangible benefits of BIM required for justification. To rank the intangible benefits of BIM, the relative importance index was adopted. Then, the rotated component matrix was conducted to correlate each intangible benefit to its estimated components. In the last phase of the research, interviews were conducted to validate and confirm the critical intangible benefits. Five critical intangible benefits were identified: better understanding of design, better information received and given, improved communication through visualization, reduce design error and improved accuracy of drawings. By knowing these five critical benefits, clients should prioritise these benefits in their justification of BIM implementation.

COST-BENEFIT ANALYSIS OF USING BIM COMPARED TO TRADITIONAL METHODS IN IRAQ'S PUBLIC CONSTRUCTION PROJECTS
