Leveraging BIM for Sustainable Construction: Benefits, Barriers, and Best Practices

Abstract

The building sector is still criticized for its excessive energy use and negative environmental effects, even with significant improvements in recent years. It makes a major contribution to the world’s energy, waste, and water use. This study investigates the possible benefits of using Building Information Modeling (BIM) technology in environmentally friendly building methods. It also seeks to identify and rank the major obstacles to the industry’s integration of sustainability and BIM. The study aims to accomplish its research objectives by means of a questionnaire survey approach. The three primary categories of the possible benefits associated with BIM are social, economic, and environmental, which correspond to the generally acknowledged elements of sustainable development. The provision of a centralized database that facilitates the administration of the full building lifetime, less material waste, and increased design efficiency have all been noted as key benefits. In the building industry, BIM approaches have shown to be quite successful in improving sustainable practices. The study does, however, point out a few difficulties. The number of people with a BIM degree has increased significantly, but there are still not enough qualified professionals with the necessary knowledge and experience. Project managers with the necessary skills are needed to oversee BIM deployment successfully. They should be able to advice and counsel clients and other stakeholders on the benefits of BIM. Building professionals may maximize the environmental performance of structures across their lifetimes and make well-informed decisions by integrating sustainability concepts into the BIM process.

1. Introduction

In recent years, the construction sector has experienced notable advancements that have revolutionized project delivery, efficiency, sustainability, and overall productivity [1]. Despite its environmental impact—using 25% of the world’s water, producing 25% of global waste, and consuming 40% of its energy—the construction sector is evolving to address these challenges [2]. Building Information Modelling (BIM), defined as “BIM is an IT-based approach that involves the use and maintenance of an integral digital representation of all building information throughout the various phases of the project lifecycle in the form of a data repository”, is a relatively recent innovation that has emerged as a crucial tool for sustainable building and development, gaining recognition for its potential advantages [3,4]. Holness [5] emphasizes the increasing adoption of BIM in response to demands for sustainable, net-zero energy buildings, and reduced carbon dioxide (CO₂) emissions. Stadel et al. [6] highlight how BIM, coupled with Life Cycle Cost Analysis (LCA), offers a precise method for carbon accounting, integrating construction material schedules, and energy consumption calculations.

BIM has gained prominence for enhancing project quality, accurate quantity take-offs, improved scheduling, and reduced costs [7,8]. Furthermore, it facilitates enhanced cooperation and correspondence between interested parties through an integrated digital stage intended for the exchange of intended data [9,10]. Beyond a 3D model, BIM incorporates multidimensional CAD information, enhancing understanding of construction phases including cost, scheduling, and environmental factors [11,12,13]. The integration of BIM in construction projects not only offers economic and environmental advantages but also improves product quality and promotes sustainable building designs [12,14]. Sustainable development, focused on responsible resource use for future generations, is further supported by BIM’s ability to engage stakeholders and enhance project outcomes [15,16]. Akadiri et al. [17] suggest that, with the help of recent technical developments, Building Information Modeling (BIM) may be an effective tool for choosing ecologically friendly building materials [18,19].

BIM’s application in sustainable buildings is exemplified by projects such as the Shanghai Centre, which achieved 40% energy savings through BIM-integrated sustainability measures [20]. The Pearl River Tower similarly utilized BIM to reduce energy costs by 30% and improve management [21]. Despite challenges in integrating sustainability data into BIM models, such as energy efficiency and life cycle assessments, BIM has been instrumental in sustainability analysis and assessment [22,23]. The integration of BIM with sustainability processes can lead to more efficient engineering and energy processes in construction, as noted by Eleftheriadis et al. [24]. Barlish and Sullivan [25] argue that BIM enhances design quality, reduces construction costs, coordinates project information, supports sustainable engineering, and accelerates project completion. Challenges remain in fully integrating BIM into sustainable practices, including workflow issues, lack of industry standards, high software costs, and resistance to change from traditional practices [26,27,28,29]. Overcoming these challenges promises increased efficiency, reduced costs, and more sustainable buildings. This research aimed at identifying and prioritizing the key advantages of integrating BIM and sustainability in construction, while also evaluating the challenges that hindered this integration. This study sought to identify and prioritize obstacles in the integration of BIM and sustainability in the construction sector, with a particular focus on developing nations.

2. Literature Review

2.1. Advantages of BIM Utilization

Building Information Modeling (BIM) integration offers several benefits for sustainable development in building projects [30,31]. Environmentally friendly building practices are becoming more and more well-known on a global scale. This method requires the creation and application of long-term plans in addition to the incorporation of cutting-edge technologies in order to accomplish its goals [32]. Sustainable building seeks to improve communities’ social and economic well-being while also promoting environmental conservation through a variety of construction activities [33]. There is a general agreement that sustainable development includes social, economic, and environmental aspects; however, there are differing interpretations of the phrase [34]. Good living standards, productivity, and a secure workplace are all dependent on sustainable buildings’ ability to properly balance environmental objectives with economic and social considerations [35]. It can be challenging to strike a sustainable balance since the three elements of “social, financial, and environmental” conflict with one another (e.g., gaining sustainable social and environmental outcomes at the price of financial sustainability) [36,37].

2.1.1. Conservational Aspect

For sustainable construction projects, BIM technology is particularly useful since it can be applied to applications that require data on energy efficiency and sustainability [38,39]. A detailed performance study of the building is possible with this sophisticated BIM model, which also enables visualizing and modeling the structure’s appearance and effects [19,38]. BIM analytics tools are crucial in sustaining the sustainability of green buildings by helping to evaluate their energy consumption, emissions of carbon, and pollution levels, among other aspects [40,41]. BIM technology also enables the analysis of water usage and the implementation of conservation measures [42,43]. Through effective site design and logistical management, it also helps to reduce waste and carbon emissions [31,42]. It also contributes to a decrease in waste and greenhouse gases through efficient site planning and logistical operations [44,45]. Project teams may use BIM to evaluate building systems, such as lighting and thermal systems, throughout their life cycles, to simulate real-world scenarios and enhance performance [46,47]. Using BIM software and tools for simulation, a structure’s environmental impact may be significantly reduced, efficiency ratings can be raised, and environmentally friendly, green societies can be encouraged [48,49]. The application of BIM programs and simulation instruments may significantly reduce a building’s carbon footprint, boost energy efficiency, and create sustainable, green communities [50]. It has been demonstrated that embracing cutting edge technology and implementing energy conservation laws in the building sector may lessen environmental effects and expedite procedures [51,52]. The use of sustainable technology with the goal of lowering energy consumption is encouraged by BIM [53,54].

2.1.2. Financial Aspect

The integration of design and project participants’ knowledge is made possible by BIM, and this may greatly increase design efficiency, lower construction costs, encourage sustainability, and enhance worker cooperation to expedite tasks and optimize performance. Not only do environmentally friendly procedures and BIM breakthroughs reduce carbon dioxide (CO₂) footprints and increase energy efficiency, but they also increase profitability and benefit the environment [55]. During a project’s whole life cycle, effective BIM adoption may lead to improved performance and increased efficiency [56,57]. Through digital project management spanning from design to operation and maintenance, BIM has completely transformed the way sustainable construction projects are managed. This development has reduced the chance of failure, managed expenses, and increased project productivity [58,59]. Throughout history, the AEC sector has continuously looked for ways to lower project costs, boost output and quality, and accelerate project completion. BIM provides a workable way to accomplish these goals [60,61]. According to Rosen and Kishawy [42], energy consumption may be decreased by choosing energy-efficient solutions with the use of BIM tools. BIM is a valuable tool for the design process, enabling the creation of solutions that enhance both the environment and project efficiency [38,62]. Also, BIM is an effective tool for organizing, controlling, and arranging for the manufacture, distribution, and purchase of all required construction components [45,56]. Project stakeholders may plan and schedule sustainable projects using BIM models, which can help to estimate construction demands, including those for materials, equipment, and money [47,63]. The use of BIM in sustainable construction projects has proven to have several benefits for all parties involved. This technology improves overall project sustainability while fostering cooperation, precision, and cost-effectiveness [52,64]. It makes it possible to generate and maintain energy-related project data and provides accurate workflow data for all of the project’s operating procedures [21]. Implementing BIM enables a precise and effective representation of the functional and physical characteristics of a structure, which may significantly reduce the cost of creating as-built drawings and save time and money [65,66].

Energy performance modelling is made possible by BIM programs, which also help find ways to lower energy needs and analyze renewable energy sources to save energy expenditures [42,67]. The design team may swiftly evaluate many design choices with the assistance of BIM analysis tools, choosing the most environmentally friendly design and making well-informed judgements [49,68]. With its ability to provide insights into the best practices for maximizing efficiency and preserving resources, BIM technology is crucial in determining the most effective ways to lower energy and resource use [44]. During the planning and design phases, it is essential to make accurate, knowledgeable judgements concerning sustainability, energy use, and the environment. A more affordable and successful sustainable design results from doing so as soon as it is feasible [44,69]. The contractor is responsible for maintaining the model up to date with actual building conditions and provides the owner with a digital 3D rendering of the structure and its components. Future operating and maintenance methods can benefit from this approach [56]. Subcontractors may utilize these BIM models for a range of installations that arise during construction. BIM-based energy simulation technologies may be used to anticipate energy savings during the design process of low-energy buildings [68,70,71].

2.1.3. Communal Aspect

It is well known that BIM improves resource management and guarantees worker safety throughout construction, which reduces waste and lowers the exposure to risks [72,73]. Information and communication technology (ICT) is used by BIM to enable information input, retrieval, sharing, and processing inside the BIM system, hence promoting cooperation among stakeholders participating in sustainable projects [21]. The activities of the Construction Industry (CI) have a beneficial influence on society that extends beyond financial advantages. These benefits include increased safety and well-being, community services, and the improved health and well-being of individuals [74,75]. BIM helps architects, builders, and managers of green buildings to improve the planning, constructing, and upkeep of environmentally friendly structures [48]. With a broad range of applications and procedures, it is a useful technique for the smooth functioning of sustainability systems and the realization of the potential of sustainable buildings [21]. Model visualization and effective building information management are two reasons why BIM technology has attracted a lot of interest in the construction sector [21]. Real-time work progress monitoring, cost estimates, identifying construction deviations, assessing construction quality, documenting product faults, and guaranteeing project completion on schedule may all be accomplished with the help of BIM [40]. BIM provides a centralized platform to manage the building life cycle from start to finish by providing all stakeholders with digital representations of the physical and functional elements of sustainable construction projects [40]. Model creation is greatly aided by BIM technology, which also makes it possible to seamlessly integrate performance simulations and visualization, making it easier to collect the information required for decision-making. A range of stakeholders may swiftly generate BIM models thanks to the BIM platform [18]. Through the use of an Integrated Project Delivery (IPD) method, BIM provides a number of advantages for sustainable and optimized design, as well as the information required for improved building performance [18]. Using ICT as a platform, BIM facilitates collaboration amongst many stakeholders throughout sustainable project development by streamlining data input, the extraction process, interchange, and transformation [76]. According to Azhar [56], management departments may design spaces, carry out maintenance, and facilitate renovations with the use of BIM. BIM is necessary to help project participants understand the benefits of sustainable development [77]. BIM may provide construction businesses with a competitive edge. This benefit enhances the company’s total competitive advantage and brand image, which in turn promotes sustainable performance and raises the company’s percentage of project wins in the industry [78]. The benefits of using BIM methodologies for sustainable practices in the building sector are shown in

2.2. Obstacles in the Implementation of BIM

BIM is a highly recommended tool for sustainable building projects since it may improve coordination and collaboration amongst all teams implicated in the building activity, which will lead to better project outcomes [90]. The construction sector still faces several obstacles when attempting to concurrently adopt sustainability and BIM, despite the benefits of doing so [91]. The industry has trouble coordinating and collaborating with stakeholders, which makes it difficult to successfully integrate sustainability and BIM [64,92].

Aksamija [79] and Olatunji et al. [92] highlight the need for a repeatable decision-making process and a collaborative work environment in the building industry to maximize the usage of BIM in promoting sustainability. Liu et al. [93] identifies several obstacles that must be overcome for BIM to be successfully implemented in sustainable practices, such as the lack of national standards, the high cost of implementation, the lack of qualified workers, organizational complexity, and legal concerns. Furthermore, the application of BIM in sustainable practices may be hampered by the absence of standards and laws pertaining to its usage. Organizations may find it difficult to comply with differing rules and regulations in several nations or areas. The lack of professionals with the necessary technical know-how and awareness of sustainable practices makes it more difficult to successfully integrate BIM into sustainable construction projects [94]. Also, one major obstacle is the high cost of employing qualified BIM specialists [94].

Although the construction industry is aware of BIM’s potential, it has not yet completely adopted the technology. This hesitancy is exacerbated by doubts about the immediate benefits of BIM, especially in the planning stage. There is less demand for BIM since some practitioners believe that it does not considerably cut down on the amount of time needed for sketching [94]. Gu and London [91] highlight the different rates of BIM adoption across different countries, demonstrating that although some firms are very proficient in BIM and long-term viability, others lack the knowledge and expertise required to implement these concepts [48]. Also, the reluctance of stakeholders to follow conventional working methods impedes the complete integration of BIM and sustainability in building projects [95].

Constructors are frequently reluctant to adopt new technology, like BIM, because of deeply ingrained traditional processes, as shown in Figure 1. Workers find it difficult to adapt to these changes because they are unable to perceive the practical benefits of BIM beyond its theoretical merits, which causes them to continue with tried-and-true techniques [94]. Ghaffarianhoseini et al. [96]. Notably, due to a lack of expertise in the field, BIM’s promise for conserving energy and the promotion of building energy efficiency has not been fully realized due to the lack of discipline-specific applications. The construction industry’s effective adoption of BIM and sustainability depends on funding possibilities for professional education and training. In the absence of this investment, a lack of skilled skills would hamper BIM’s advancement in environmentally friendly construction design and development [97].

Aranda-Mena et al. [99] show that the use of BIM results in increased resource needs, which include costs for specialized software and other resources that are required. Even though BIM technology has advanced significantly and is widely used, there is still little study on how it affects sustainable construction practices because of the added resources and high implementation costs [100]. The lack of professionals with both BIM and environmental experience greatly impedes the effective implementation of BIM software in sustainable building projects. There is a dearth of experts who are able to effectively combine and use BIM software and environmentally friendly building methods as they are relatively new concepts in the globe, according to the body of research [101,102].

Zahrizan et al. [103] identify the following as obstacles to successful adoption: low participation in BIM use for sustainable projects; unclear rules for using BIM in sustainable construction projects; and the absence of a developed structure or standards supported by BIM for achieving sustainability. One significant issue is the lack of data exchange between BIM models and energy analysis systems for operational management. It might be challenging to integrate sustainability and BIM into projects without the appropriate definitions, protocols, and processes. Gathering data at various stages of the building’s life is crucial to the effective operation and maintenance of the energy systems that occupants use [104].

The need for estimations for loads, air fluxes, and heat transfer is one of the challenges of utilizing BIM for energy analysis; this can result in unpredictable and unreliable simulation results [70,104]. In all evaluated field tests, Autodesk Ecotec underestimated the thermal loads, and 98% of field measurements revealed exaggerated illuminance levels, according to a study of a LEED Gold-certified university building in the United States [105].

Adamus [106] asserts that facts about sustainability cannot be properly encoded using the current BIM data standards. Bradley et al. [107] discuss how techniques such as ontologies and linked data approaches are employed to integrate concepts like sustainability, but they require a strong foundation in computer programming. Maximizing the potential of BIM and filling in persistent knowledge and application gaps require a well-thought-out plan. It would be difficult to apply BIM in sustainable practices without a comprehensive framework and implementation plan [108].

The use of BIM has increased significantly over the past 10 years as the building industry has adopted more advanced technologies to increase productivity. However, the potential for adopting BIM to improve building site safety has not received enough attention, particularly in regard to temporary buildings [109]. Kivits and Furneaux [110] discover that there may be additional legal liabilities and unforeseen risks associated with the use of BIM in sustainable building projects. The degree to which BIM is prioritized in sustainable projects by upper management is one of the key elements in the integration of BIM technology with sustainability systems. On the other hand, if management disapproves of BIM implementation, it cannot succeed [21]. The adoption of BIM by designers is influenced by several factors such as technical needs, personal incentives, and senior management support [111]. Abubakar et al. [95] highlight the fact that the integration of BIM and sustainability practices will not be possible if senior management’s responsibility is ignored.

For practitioners, integrating and embracing new technology in application management presents a big psychological hurdle [95]. The efficient application of Building Information Modelling (BIM) in the construction of green buildings is hampered by technicians’ frequent opposition to adopting new ideas and technology [21]. It is important to assess a building’s performance using several BIM criteria—environmental, social, and economic—and include this information into the design framework so that options may be compared in order to achieve effective sustainable design [78]. There are several benefits of integrating Life Cycle Assessment (LCA) with BIM for sustainable practices. However, the lack of uniform BIM and sustainability standards and metrics might prevent these domains from being successfully integrated [78]. The difficult obstacles that come with integrating BIM methods into environmentally friendly construction procedures are outlined in

3. Methodology

Figure 2 shows the online survey that was used in this study, which collected data using a quantitative methodology.

3.1. Development of Questionnaire

The purpose of the carefully crafted questionnaire was to investigate the benefits of combining sustainability with BIM in the building sector. To ensure that the questions were pertinent and thorough, a panel of experts in BIM, sustainability, and construction was assembled. Thirty members of the target group participated in pilot research that aimed to improve clarity and prevent ambiguity. The purpose of this preliminary test was to confirm the survey questions’ dependability and correctness. The pilot study’s feedback was examined to find any problems or potential areas for development. As a result, the questionnaire was refined, as shown in Appendix A, including rephrasing unclear questions, removing redundant items, and ensuring a logical and easy-to-follow structure. The reliability of the questionnaire was measured using Cronbach’s alpha (Cα), which assesses internal consistency. Cronbach’s alpha ranges from 0.0 to 1.0, with higher values indicating greater reliability. For this study, Cα was calculated to be 0.837, surpassing the commonly accepted threshold of 0.7. This confirmed the questionnaire’s internal consistency and suitability for the full-scale study. By following these steps, the questionnaire was meticulously developed and validated to ensure it accurately captured the views and experiences of construction industry professionals regarding the integration of BIM and sustainability practices. The high-reliability scores further indicated that the responses would be consistent and dependable, providing a solid foundation for subsequent data analysis.

3.2. Distribution of Questionnaire

A target demographic including civil engineers, architects, mechanical engineers, and electrical engineers who are knowledgeable about BIM and sustainability in the Gaza Strip, Palestine, was given the questionnaire. Professionals with knowledge of BIM and sustainability from the Gaza Strip’s building industry were especially included in this target group. Participants were gathered using the snowball sampling technique, which works well for locating and interacting with a niche group of people. Non-probability approaches were used to choose the initial respondents, and these initial respondents’ suggestions were used to attract further participants. Both in-person and online survey distribution channels were used to distribute the questionnaire. While the web-based approach provided for a wider audience and distant engagement, the in-person distribution allowed for direct communication with participants. Out of the 100 questionnaires that were issued, 89 of them were successfully completed, yielding an 89% response rate. This technique improved the accuracy of the data gathered and resulted in a high response rate. The questionnaire was sent to professionals with relevant BIM and sustainability expertise and experience thanks to the snowball sampling approach, which made use of pre-existing networks and recommendations from early respondents. The combination of in-person and online distribution methods allowed for thorough coverage of the intended audience and the collection of responses that represented a wide variety of viewpoints. The high response rate strengthened the authenticity and dependability of the data gathered and provided a solid basis for future investigation.

3.3. Statistical Validity of the Questionnaire

A correlation analysis between the variables within each questionnaire category was carried out to guarantee the statistical validity of the quantitative research instrument. This study contributes to the confirmation that the questionnaire successfully assesses the objectives for which it was designed. The questionnaire’s validity was evaluated using a pilot study and a subsequent correlation analysis.

* The correlation is statistically significant at the 0.05 level.

. For every factor, the correlation coefficient (r) and p-value were determined. The results show that all correlation coefficients are statistically significant at the 0.05 level *, with p-values less than 0.05. This implies that the measures utilized to assess these challenges are trustworthy and stable when assessing the intended idea. The statistically substantial correlation coefficients between each item in the domain and the domain total score attest to the validity of the items.

The correlation analyses presented in Table 3 and Table 4 demonstrate the statistical validity of the questionnaire used in this study. The questionnaire items effectively measure the intended constructs related to the potential benefits and difficult challenges of integrating BIM techniques into sustainable practices in the construction industry, as evidenced by the high correlation coefficients and statistically significant p-values. These findings attest to the validity of the questionnaire as a means of gathering information and evaluating the opinions and experiences of professionals pertaining to BIM and sustainable integration in the Gaza Strip, Palestine.

3.4. Reliability of the Research

A research instrument’s consistency and stability in producing consistent results over time is what makes it reliable. A commonly used indicator of internal consistency, the Cronbach’s alpha coefficient, was used in this study to assess the questionnaire’s reliability. To assess the internal consistency of the questionnaire, Cronbach’s alpha (Cα) was computed for every part and the whole instrument. The range of Cronbach’s alpha values is 0.0 to 1.0, where larger values correspond to increased dependability and reliability [113,114]. (See

Table 5. Cronbach’s alpha for each aspect of the questionnaire and the entire questionnaire.

Aspect	No. of Items	Cronbach’s Alpha
Benefits of using BIM methods in the building sector for sustainable practices	49	0.837
Conservational aspect	15	0.802
Financial aspect	17	0.825
Communal aspect	17	0.798
Barriers to the building industry’s adoption of sustainable practices through the incorporation of BIM methodologies	17	0.855
All questionnaires	68	0.854

).

The questionnaire has a high degree of internal consistency in every area. The strong Cronbach’s alpha scores for the full questionnaire and for each part show how trustworthy the research instrument was for this study. The questionnaire appears to measure the constructs it was intended to test consistently, as seen by the satisfactory internal consistency among the items in each part. As a result, the information gathered via this questionnaire may be trusted to be accurate when used for additional research on incorporating BIM methods into environmentally friendly practices in the Gaza Strip’s building sector.

3.5. Data Analysis Tests

Statistical analysis of the data obtained from the survey was conducted using SPSS Version 23. During the data analysis process, several quantitative measures were used, as explained below.

3.5.1. Relative Importance Index (RII)

The relative relevance of each element within the groups was determined using the Relative Importance Index (RII) approach. Except for 0, the RII value is between 0 and 1. The following formula can be used to determine RII.

$${\overline{X}}_W={\displaystyle \frac{\sum W}{AN}}={\displaystyle \frac{5n_5+4n_4+3n_3+2n_2+1n_1}{5N}}$$

(1)

where W is the weight assigned by respondents to each factor, ranging from 1 to 5; A: is the maximum possible weight, which is 5 in this study; and N is the total number of respondents, which is 89 in this study.

3.5.2. One sample t-test

The purpose of the One-Sample t-Test was to determine if the meaning of a given dataset substantially deviates from a specific value, which in the case of Likert scale data [115] is usually “3”. A significance threshold (α) of 0.05 was used. If there was a significant difference between the mean and the assumed value, it was determined using the test statistic (t) and the corresponding p-value (Sig.).

3.5.3. Independent Samples Test

The means of two separate populations were compared using the separate Samples Test, a parametric analysis, to see if there was statistical support for a significant difference between them.

3.5.4. One-Way Analysis of Variance (ANOVA)

One statistical technique to ascertain if the means of several groups are equal is the ANOVA (F-test). It works well in scenarios involving more than two groups. To test the hypothesis that group means are equal, ANOVA is used. Rejecting this hypothesis means that at least one group is very different from the rest.

3.5.5. Paired t-Test

A statistical technique called the Paired t-Test is used to compare the means of two related or dependent samples and assess if there is a statistically significant difference between them. When collecting paired or dependent data, such measurements taken before and after, this test is acceptable. These statistical methods were chosen based on the properties of the data and the research questions that were being investigated. They provide trustworthy techniques for analyzing the data acquired from the survey on the use of BIM techniques to green building approaches in the Palestinian Gaza Strip. By assisting in the understanding of the significance of variables, comparing group means, and evaluating changes before and after treatments, these procedures guarantee a comprehensive assessment of the research data.

4. Results and Discussion

The results of the analysis of the survey data are shown in this section. After the data were arranged, examined, and assessed, judgments regarding the objectives of the research might be drawn. The results are discussed and presented in an intelligible manner, and appropriate statistical techniques are used to bolster the conclusions.

4.1. Demographic Information about the Respondents

The questionnaire results were analyzed to determine the demographics of the 89 supervising engineers working in the construction sector, covering positions such as Project Manager, Site Engineer, and Office Engineer, among others. Figure 3 presents an overview of the respondents’ profiles.

Most respondents in this survey were male, which is consistent with the reality that the construction industry remains male-dominated. Furthermore, most respondents had a master’s degree in civil engineering. In terms of workplace, the government sector had the largest share, followed by contractors, non-governmental organizations, other workplaces, and consultants. Additionally, most respondents worked as office engineers, with the remainder holding various other positions. The bulk of respondents had more than ten years of construction experience.

The data also indicated that most of the engineers had previously attended BIM training courses or workshops. Moreover, the findings revealed that most of the research sample, consisting of engineers, had a substantial awareness of the concept of sustainability. Specifically, 92.1% reported having received training in the form of workshops and lectures on sustainability, while 7.9% of the sample stated they did not know what the issue was.

These findings underscore the need for continued focus on BIM and sustainability education, highlighting the existing awareness and experience levels within the industry. Further efforts should be directed towards ensuring that all industry professionals, regardless of gender, education, or experience, are well equipped to integrate BIM and sustainable practices into their work.

The demographic profile of the respondents provides insights into the characteristics of the sample population. Most respondents were well-educated, with a master’s degree in civil engineering, and had significant experience in the construction industry. The dominance of males in the sample reflects the broader gender distribution within the construction sector.

The high level of BIM training among respondents suggests familiarity and competence with BIM techniques, which is crucial for integrating BIM into sustainable practices. Moreover, the substantial training in sustainability indicates a growing awareness and knowledge of sustainability principles among the respondents, although a small percentage still lacks familiarity with the concept. This demographic data are essential for understanding the outcomes that follow from using BIM methodologies in sustainable practices. It provides a framework for comprehending how the traits of the respondents could affect their attitudes and views about sustainability and BIM in the building sector.

).

The respondents’ average ratings for all items in the economic advantages section ranged from 3.98 to 4.42, with an overall mean of 4.21 and an RII of 84.11%, indicating a very high level of agreement. This suggests that utilizing BIM techniques in sustainability practices can yield significant economic advantages in the construction sector.

The top-ranked benefit, “Enhancing design efficiency”, received a mean rating of 4.42 and an RII of 88.31%, indicating strong agreement among respondents. BIM enhances design efficiency and economic performance by minimizing errors and coordinating designs to save time and expenses, enabling collaborative working processes and an information-rich nD model, reducing change orders and associated costs during execution, and improving energy efficiency through a clear visualization of construction stages. Clash detection, a prominent feature of BIM, plays a critical role in this process by identifying and resolving conflicts early in the design phase. This proactive approach prevents costly errors and rework, further contributing to cost savings and project efficiency. Notably, one of the most significant benefits is clash detection in pipelines, which identifies and resolves conflicts early, thereby avoiding costly errors and rework. This finding aligns with the study by Shi et al. [55], which suggests that implementing BIM during the design stage optimizes design efficiency, lowers construction costs, and enhances sustainability. The analysis demonstrates that BIM can significantly improve economic performance in construction by enhancing efficiency, controlling costs, and optimizing project management. These economic advantages support the case for adopting BIM techniques in sustainability practices within the construction industry.

	Total degree for all items	4.04	0.51	80.83	-

based on the degree of unanimity.

The average responses of the sample members to all items in the third aspect (social advantages) ranged from a minimum of 3.75 out of 5, with a relative importance index of 75.06% and a high agreement level for the item stating “Enhancing the quality of life for individuals”, to a maximum of 4.34 out of 5, with a relative importance index of 86.74% and a very high agreement level for the item stating “Providing a centralized database that supports the management of the entire building life cycle process”. The overall average response to all items is 4.04 out of 5, with a relative importance index of 80.83%, indicating a high level of agreement. This demonstrates that the mentioned social advantages will be achieved by utilizing BIM techniques in sustainability practices within the construction sector.

The respondents have ranked the result “Offering a centralized database that supports the management of the entire building life cycle process” as the most important one. BIM generates comprehensive digital representations of a constructed asset at every stage of its lifespan, from planning and design to construction and operations, by combining data from several disciplines. Better judgment and more sustainable solutions are made possible as a result. BIM also helps with the planning of construction projects and improves procedures, which results in better, more sustainable structures while resolving problems. These findings are consistent with Manzoor et al. [40], who highlighted the advantages of using BIM as a central database in managing the building life cycle.

displays the tasks in descending order.

The average responses to all items ranged from a minimum of 3.44 out of 5, with a relative importance index of 68.76%, indicating a high level of agreement for the challenge related to “Substantial cost of training staff”, to a maximum of 4.17 out of 5, with a relative importance index of 83.37%, reflecting high agreement on the issue of “Deficiency of skilled personnel to implement BIM projects”. Overall, the average response for all items was 3.80 out of 5, with a relative importance index of 75.53%, highlighting a strong consensus on the identified challenges. Notably, an increased workload due to frequent revisions of BIM models from design to construction phases can significantly impact efficiency, and there is a pressing need for clear guidelines on the type of BIM data required for transition from construction to operation and maintenance. Sophisticated understanding and instruction are crucial for effective BIM utilization. Skilled project managers play a vital role in advising stakeholders and managing BIM procedures, as a lack of awareness and understanding of these challenges can result in considerable time and financial losses. These findings are consistent with the studies of Akcay [116] and Liu et al. [93], who also identified the shortage of skilled personnel as a major obstacle to BIM implementation in the construction industry.

4.4. Relationship between the General Information of the Study Participants and Their Opinion about the Capabilities (Advantages and Challenges)

4.4.1. Analysis Considering Gender

A statistical technique to ascertain if there is a significant difference between the means of two groups is the independent samples t-test. It is frequently used to compare the opinions or traits of two different groups, which were, in this example, the respondents who are male and female, in order to see if there are any appreciable differences between them. This test aids in ascertaining if any variations between the two groups that are found are the product of random variation or a true variation in the population. Given that the probability values for each aspect are greater than the 0.05 threshold,

Table 11. Independent sample t-test results regarding the gender of the respondents.

Aspects	t-Test	p-Value (Sig.)	Means
			Male	Female
Benefits of using BIM methods in the building sector for sustainable practices	0.388	0.699	4.14	4.09
Obstacles to the building industry’s adoption of sustainable practices through the integration of BIM methodologies	0.376	0.708	3.78	3.72

’s results show that there is no statistically significant variation in the study participants’ perceptions of the capabilities of BIM technology for sustainable building practices based on gender. It is possible that participants male and female had comparable levels of expertise and familiarity with BIM technology, or that their gender had little impact on how they perceived the benefits and drawbacks of BIM. It is also likely that any disparities in participant perceptions of BIM technology between male and female participants are too small to be picked up on by statistical analysis. To learn more about the possible impact of gender on opinions toward BIM technology, more studies should be conducted.

4.4.2. Analysis Considering Educational Qualifications

The results of the t-test analysis, presented in

Table 12. One-way ANOVA results regarding educational qualifications.

Aspects	F-Test	p-Value (Sig.)
Benefits of using BIM methods in the building sector for sustainable practices	5.729	0.005
Obstacles to the building industry’s adoption of sustainable practices through the integration of BIM methodologies	4.986	0.009

, indicate that there is a statistically significant difference in the perceptions of study participants regarding the capabilities of BIM technology for sustainable building practices based on their educational qualifications. Specifically, the probability values for each aspect are less than the 0.05 significance level, indicating that individuals with higher educational qualifications have a distinct perception of the advantages and challenges of BIM technology compared to those with lower qualifications. Individuals with higher educational qualifications may have more exposure and experience with BIM technology through their academic and professional training, leading to a greater understanding of its capabilities and potential challenges. They may also have a deeper understanding of sustainable building practices and the role BIM technology plays in supporting those practices. Additionally, individuals with higher educational qualifications may have greater critical thinking and problem-solving skills, which could enable them to evaluate the advantages and challenges of BIM technology more effectively.

4.4.3. Analysis Considering Engineering Specialization

The use of t-test analysis revealed that there is no statistical significance in the perceptions of study participants regarding the capabilities of BIM technology for sustainable building practices based on their engineering specialization. The results, presented in

Table 13. One-way ANOVA results regarding engineering specialization.

Aspects	F-Test	p-Value (Sig.)
Benefits of using BIM methods in the building sector for sustainable practices	1.271	0.288
Obstacles to the building industry’s adoption of sustainable practices through the integration of BIM methodologies	0.716	0.583

, indicate that the probability values for each aspect are above the 0.05 threshold, indicating no significant difference. This could be because BIM technology is used across various engineering disciplines and thus is perceived similarly by participants irrespective of their specialization. It could also be due to the fact that BIM technology is becoming more prevalent and widely used across the engineering industry; thus, engineering specialization may not have a significant impact on perceptions of its capabilities.

4.4.4. Analysis Considering Position

The probability values for each component appear to be greater than the pre-established threshold of 0.05, according to the data shown in

Table 14. One-way ANOVA results regarding the position of the respondents.

Aspects	F-Test	p-Value (Sig.)
Benefits of using BIM methods in the building sector for sustainable practices	1.277	0.287
Obstacles to the building industry’s adoption of sustainable practices through the integration of BIM methodologies	2.624	0.056

. This suggests that there is not any hard proof of differences in research participants’ views about the capabilities and limitations of BIM technology for environmentally friendly building practices that would be consistent with their positions within the companies. It could be that the roles and responsibilities of the participants were not diverse enough to create significant differences in their perceptions, or that the implementation of BIM technology was integrated throughout the organizations in a way that minimized differences in perception based on position. Further research may be needed to explore these possibilities in more depth.

4.4.5. Analysis Considering Construction Working Experience

The results presented in

Table 15. One-way ANOVA results regarding the construction working experience of the respondents.

Aspects	F-Test	p-Value (Sig.)
Benefits of using BIM methods in the building sector for sustainable practices	0.076	0.926
Obstacles to the building industry’s adoption of sustainable practices through the integration of BIM methodologies	0.770	0.466

indicate that there is no statistically significant difference in the perceptions of the study participants regarding the capabilities of BIM technology for sustainable building practices, as determined by the probability values calculated for each aspect, which are all greater than the commonly accepted significance level of 0.05. This suggests that the level of construction working experience of the participants does not have a significant impact on their perceptions of the advantages and challenges of BIM technology for sustainable building practices. It is possible that the participants with varying levels of experience had similar exposure and training to BIM technology, which could have led to similar perceptions of its capabilities. Additionally, their experience level may not necessarily correlate with their familiarity or proficiency with BIM technology. Other factors, such as their educational background or the type of projects they have worked on, may have had a greater impact on their perceptions of BIM.

4.4.6. Analysis Considering Workplace

The findings from

Table 16. One-way ANOVA results regarding the workplace of the respondents.

Aspects	F-Test	p-Value(Sig.)
Benefits of using BIM methods in the building sector for sustainable practices	0.652	0.627
Obstacles to the building industry’s adoption of sustainable practices through the integration of BIM methodologies	0.577	0.680

indicate that there is no statistically significant difference in the perceptions of the study participants regarding the capabilities of BIM technology for sustainable building practices based on their workplace, as the probability values for each aspect are greater than the 0.05 significance level. As the participants in the study came from a range of workplaces with similar levels of exposure and experience with BIM technology for sustainable building practices, their workplace did not significantly influence their perceptions of its capabilities for sustainable building practices.

5. Conclusions and Recommendations

5.1. Conclusions

BIM and sustainable practices must be integrated to create a sustainable smart city in the building sector and to establish new benchmarks. Whether BIM can help building projects adopt sustainable practices has been the subject of several studies. The potential advantages of using BIM techniques to increase sustainability in the construction sector are listed and ranked in this study.
