1. Introduction

In the evolving landscape of the global construction industry, safety management has emerged as a pivotal cornerstone, reflecting a collective aspiration towards creating zero-accident workplaces [1,2]. This ambition goes beyond mere altruism, pragmatically responding to the substantial human and financial costs associated with construction-related mishaps. A stark illustration of the dire safety landscape within this sector is the tragic collapse of a scaffolding structure in 2019, resulting in multiple fatalities and injuries. This incident, among countless others, underscores the stark reality that construction sites remain some of the most perilous work environments globally [3,4].

Recent data highlights the urgency of this issue: a 2021 report by INAIL revealed an alarming 312,762 accident claims within just seven months, including 677 fatalities. Such statistics are not isolated anomalies but rather reflect a global trend. The International Labour Organization (ILO) estimates approximately 60,000 fatalities at construction sites worldwide annually, painting a harrowing picture where, on average, a life is lost every nine minutes [5]. Thus, the construction sector bears the dubious distinction of having the highest fatality rate compared to other industries, such as manufacturing and services, underscoring an urgent need for comprehensive safety interventions [6].

The multifaceted risks inherent in construction projects—from operating heavy machinery to executing tasks at significant heights—underscore the complexity of ensuring workplace safety [7]. Traditional approaches to safety management, often reactive and fragmented, have proven inadequate in addressing the inherent risks present in dynamic construction environments [8]. This inadequacy stems not from a lack of effort but from the inherent limitations of conventional methods to anticipate and mitigate the array of potential hazards.

Against this backdrop, the advent of Building Information Modeling (BIM) technology offers a transformative opportunity for the construction industry [9,10]. BIM transcends traditional modeling by integrating risk assessment and mitigation strategies directly into the design and execution phases of construction projects [11]. This capability is not merely about creating comprehensive, interactive models but enabling a significant shift from reactive to proactive safety management. By embedding safety considerations into every stage of the project lifecycle, BIM ensures that potential risks are identified and addressed well in advance, thus enhancing the overall safety framework [12]. By integrating risk assessment and mitigation strategies directly into both the design and execution phases, BIM facilitates a holistic approach to safety, emphasizing prevention and early intervention [13].

This study harnesses the capabilities of BIM, proposing a novel methodology that extends the use of BIM models beyond mere design and planning tools. BIM models serve as dynamic platforms for comprehensive risk management. During the design phase, the models are systematically enriched with parameters that detail potential risks, transforming BIM into a proactive tool that facilitates the early identification and mitigation of hazards before the onset of construction. The enrichment involves integrating data on material properties, environmental factors, and construction sequences, thereby anticipating potential failures and operational challenges. This proactive stance is maintained throughout the construction phase, where BIM-enabled simulations offer real-time visibility into the unfolding project. Such visibility enables the project team to perform timely interventions, effectively preventing accidents and enhancing safety outcomes. The integration of BIM into daily construction operations involves constant updates from real-time data, which allows for ongoing risk assessments and adjustments to the construction processes, ensuring continuous safety management.

By conducting an extensive review of both the national and international literature on construction site management, this research significantly contributes to the body of knowledge, situating its findings within the broader context of ongoing efforts to enhance industry safety standards. Through its innovative application of BIM for risk assessment and mitigation, this study not only offers a blueprint for safer construction practices but also highlights the potential of technology to revolutionize traditional approaches to safety management.

2. State of the Art

The integration of digital technologies into construction and infrastructure design has significantly transformed the industry, yet the full potential of these technologies to enhance safety is still being explored [14,15]. Recent advancements in machine learning (ML) have shown great potential in forecasting and preventing construction-related injuries. For example, models developed by Tixier et al. [16] have been instrumental in predicting injuries affecting critical areas such as the upper limbs, back, and trunk, paving the way for proactive safety measures. These predictive models analyze patterns from vast datasets to identify risk factors associated with construction activities.

However, despite their promise, the application of machine learning in construction safety remains fragmented and underutilized. The primary limitations include:

• Machine learning models require large volumes of high-quality data to train effectively. In the construction industry, the inconsistent recording of incident reports and the variability in data collection standards across sites pose significant challenges to developing robust models [17].
• Many construction sites lack the digital infrastructure necessary to integrate advanced ML predictions into daily operations. As a result, even when models predict potential incidents, mobilizing preventive actions on-site can be slow and inefficient [18].
• Machine learning models often need retraining to adapt to different types of construction environments or to scale across various projects, which can be resource-intensive [19].

Further research into the nexus between construction safety and digital design practices, undertaken by scholars like Farghaly et al. [14] and Akinlolu et al. [15], demonstrates an increasing interest in employing technology to create safer construction environments. Abed et al. [20] introduction of a 4D Building Information Modeling (BIM) reference model for analyzing and mitigating severe accidents, including falls from height, offers a hopeful blend of digital tools and safety protocols. Yet, the real-time application of these models in construction scenarios is nascent, underscoring a notable gap in the practical deployment of such technologies.

Digital methodologies such as the Occupational Health and Safety (OHS) approach by Hoeft and Trask [21] and the conduit optimization method by Martínez-Airesa et al. [22] illustrate the potential of digital technologies to improve construction safety from the design phase through to dismantling. Nonetheless, these developments often happen in silos, lacking a unified framework to tackle the broad spectrum of risks inherent in construction projects.

The utilization of 4D BIM and 3D point cloud technologies, as demonstrated by Li et al. [23], brings a significant innovation in monitoring construction progress through real-time, immersive visualizations. While these technologies primarily serve to track project progress, their potential extends into proactive safety management and risk mitigation.

Four-dimensional BIM facilitates dynamic simulations of construction processes over time, making it a valuable tool for safety planning. These simulations allow for the visualization of future construction activities, enabling safety managers to identify and address potential risks before they occur [24]. The integration of 4D BIM into the BIM-based methodology enhances the capability to anticipate and mitigate risks by aligning the project’s timeline with safety interventions strategically.

Three-dimensional point cloud technology, on the other hand, provides precise geometric information about the construction site by capturing detailed measurements of the physical space. This technology can be leveraged to create a highly accurate digital twin of the site, which serves as a reference model throughout the project lifecycle [25]. By comparing the digital twin with the 4D BIM simulations, discrepancies that may indicate safety risks, such as unexpected structural changes or deviations from the planned process, can be quickly identified and addressed.

An in-depth review of the current literature and practices reveals a fragmented application of digital technology in enhancing construction safety. The emphasis on individual technologies or specific safety concerns fails to address the need for a holistic, integrated approach to risk management throughout the entire project lifecycle [26,27]. This research seeks to close this gap by amalgamating diverse perspectives into a cohesive methodology that utilizes BIM for risk assessment and mitigation. By leveraging BIM not merely as a design tool but as a dynamic platform for ongoing risk evaluation and mitigation, this approach establishes a comprehensive framework that transcends traditional, reactive safety measures.

2.1. Comparative Insight: Key Technologies vs. BIM in Safety Management

This section provides a detailed benchmarking analysis of Building Information Modeling (BIM) against other key technologies used in construction safety management (

Notes: ⁽¹⁾ The parameters for evaluating machine learning technologies in construction safety are informed by the latest research publications that discuss data integration challenges and the effectiveness of predictive analytics. ⁽²⁾ These are based on academic papers and industry reports that discuss the benefits and challenges of implementing 4D BIM in large-scale projects. ⁽³⁾ The criteria were chosen based on case studies demonstrating how digital twins have been employed in the construction sector to monitor and manage projects in real time. ⁽⁴⁾ Derived from official safety regulations and widely accepted safety management practices that highlight the adaptability and rigidity of traditional OHS approaches.

). The goal is to critically assess the relative strengths and weaknesses of each technology, using a systematic approach to highlight how BIM provides a more integrated and dynamic solution.

The technologies chosen for comparison with BIM include Machine Learning (ML), 4D BIM, Digital Twins, and traditional Occupational Health and Safety (OHS) methodologies. These technologies were selected based on their current and potential impact on safety management in the construction industry.

Each technology was evaluated based on the following criteria:

• Ability to predict, detect, and mitigate risks.
• Capability to integrate with ongoing site operations and data flow.
• Costs associated with implementation and ongoing use.
• Suitability for various project types and ability to accommodate changes.

Data were collected from a variety of sources including industry reports, peer-reviewed journals, and case studies detailing the implementation and outcomes of these technologies in real-world construction projects.

The comparative analysis used a combination of qualitative assessments and quantitative metrics. Quantitative data were analyzed using statistical tools to evaluate the performance and impact of each technology on project safety outcomes. Qualitative data, including expert opinions and case study findings, provided context and insights into the usability and integration of the technologies.

The analysis demonstrates that while each technology has its strengths, BIM offers a more comprehensive framework by integrating the benefits of each. For instance, BIM complements ML by providing a framework where predictive data can be continuously updated and applied, enhancing real-time decision-making. Similarly, the integration of Digital Twins within a BIM framework leverages real-time data for ongoing risk assessment, allowing for immediate adjustments in safety strategies based on live updates from the construction site.

This benchmarking exercise highlights the multifaceted benefits of BIM in overcoming the limitations of other technologies, reinforcing the need for an integrated approach that utilizes the strengths of BIM to advance safety management in construction projects. By employing a systematic benchmarking methodology, this analysis provides a clear, data-driven foundation for recommending BIM as the superior choice for enhancing safety management practices in the construction industry.

While ML offers significant capabilities in predicting injury types and occurrences, its effectiveness is hampered by issues like the need for vast, high-quality data sets, and the lack of integration with real-time site operations. BIM complements ML by providing a framework where predictive data can be continuously updated and applied, enhancing real-time decision-making.

Four-dimensional BIM technology is instrumental in planning safety by visualizing construction processes over time. However, its complexity and the costs associated with implementing such detailed simulations can be prohibitive. The BIM-based methodology simplifies the integration of 4D simulations, making it more accessible and cost-effective by embedding these capabilities within the standard project workflow.

Typically used for monitoring, digital twins are less commonly employed for integrated risk management. By incorporating digital twins within a BIM framework, this methodology leverages real-time data for ongoing risk assessment, allowing for immediate adjustments in safety strategies based on live updates from the construction site.

Traditional Occupational Health and Safety (OHS) approaches provide rule-based safety management, which can be rigid and not easily adapted to different projects or unexpected changes in the field. BIM enhances these methodologies by allowing for dynamic updates and integration of safety protocols directly into the project model, thus providing flexibility and adaptability.

This comprehensive comparative analysis aims to highlight the multifaceted benefits of BIM in overcoming the limitations of other technologies, reinforcing the need for an integrated approach that utilizes the strengths of BIM to advance safety management in construction projects.

2.2. Analysis of the State of Art

In this paragraph, the stages of the approach used for studying the state of the art in literature are examined. The following stages were followed: data collection, quality assessment, keyword normalization, and information analysis. The collection of scientific studies was based on selecting the most appropriate keywords and the corresponding database as a source of information. The chosen research database was Scopus, which has the largest number of articles related to the topic.

The search was conducted within all articles, abstracts, and keywords in the database, using the following queries: “construction site layout management and design”, “as-sembly on-site”, “digital twin”, “smart construction”, “virtual reality”, “scheduling”, “BIM4D”, “machine learning”, “artificial intelligence construction”. To further narrow down the research field to relevant articles only, filters were applied, selecting articles published in the last ten years (2013–2023) and those within engineering and computer science disciplines. After this selection, the search yielded a total of 550 documents. The collected data were exported in RIS (Research Information System) file format and imported into VOSviewer version 1.6.20, a software allowing analysis and quantification of the total number of citations of a work, author, theme, or discipline, also enabling the identification of citation networks. Once the RIS files were loaded into the program, the normalization phase was executed to obtain more homogeneous keywords, setting specific parameters.

For instance, in the case of keywords composed of a combination, the full expression was selected, such as “Building Information Model (BIM)” becoming “Building information model”. Additionally, all words containing symbols were replaced with a space, for example, “ma-chine-learning” became “machine learning”, and keywords not relevant to the research, like “Architectural design”, were manually excluded. With the parameters set, the program filtered the records from 1552 to 31 keywords and produced a graphical organizer to visualize the interactions between topics. From the analysis of the graph, it emerges that there are no particularly prominent keywords compared to others, except for Building Information Modeling and Digital Twin. Especially in the construction sector and safety on construction sites, it is possible to observe how these terms are highly relevant and interconnected, indicating a significant focus of research in these areas.

This is because several applications have already been analyzed in the field of safety, such as BIM 4D, which allows simulating construction site progress through a timeline. From this analysis of the state of the art, it is evident how the paper involves all three contents, as it utilizes the BIM methodology to recreate a digital model of the construction site to prevent risks during the execution phase. Analyzing the connections generated between the various queries, particularly those related to the blue-colored cluster, it is possible to notice how they appear slightly shifted compared to the others, due to their lesser affinity with the rest of the keywords.

Finally, VOSviewer allows visualizing the chronological order of the publication dates of the selected articles, indicating the timeliness of the topics addressed. The analysis reveals that the earliest publications date back to the beginning of 2020, and more precisely, only from 2022 onwards has there been a growth in publications regarding construction site organization combined with the digital twin using the BIM methodology.

3. Methodology

The proposed methodology integrates advanced Building Information Modeling (BIM) techniques with core principles of safety management to significantly enhance risk identification, assessment, and mitigation across construction projects. By leveraging BIM’s extensive capabilities beyond traditional design and visualization, it serves as a critical platform for comprehensive safety analysis and proactive decision-making throughout the project lifecycle.

The methodology unfolds in a well-structured iterative process, encompassing three primary phases: Preliminary Analysis, Design, and Execution. Each phase is supported by specific tools and strategies to optimize safety outcomes (Figure 1).

3.1. Preliminary Analysis Phase

• Objective: Establish a comprehensive safety management foundation within the BIM framework at the project’s outset, ensuring that safety considerations are deeply integrated into the project structure from the beginning.
• Key Activities:

• BIM Model Assessment:
  • Conduct a detailed evaluation of the received BIM model using Autodesk Revit to ensure its completeness and level of detail are sufficient for comprehensive safety analysis.

  • Develop and set parameters that represent critical safety risk factors associated with various construction activities and site conditions. This step includes analyzing past incidents, industry standards, and regulatory requirements to inform the parameters.
  • Utilize tools like Dynamo to automate the integration of these safety parameters into the BIM model, enhancing the efficiency and accuracy of the process.
• Risk Identification and Prioritization:
  • Create a preliminary risk matrix using the embedded safety parameters in the BIM model. This matrix provides a visual representation of potential risks categorized by their probability and severity, which helps in prioritizing safety efforts.
  • Employ visualization tools within BIM software, such as Navisworks, to aid project teams in easily understanding and addressing safety issues highlighted by the risk matrix.
• Stakeholder Engagement and Feedback:
  • Engage with all relevant stakeholders, including project managers, safety officers, and design teams, to review the established LOIN, safety parameters, and risk matrix.
  • Integrate feedback from these sessions to refine the safety parameters and risk matrix, ensuring they accurately reflect the project’s needs and stakeholder insights.
• Documentation and Reporting:
  • Document all safety parameters, risk assessments, and mitigation plans developed during this phase to ensure transparency and traceability.
  • Prepare reports that summarize the findings and preparations made during this preliminary phase to keep all project participants informed and aligned.

• Deliverables:

• A fully assessed and updated BIM model ready for the design phase.
• A comprehensive set of safety-specific parameters integrated into the BIM model.
• A preliminary risk matrix to guide further safety planning and mitigation efforts.

In the proposed methodology, a Dynamo script that quantifies risk levels associated with working at heights was utilized, which is a critical safety aspect in construction projects (Figure 2). The script evaluates risk based on three main parameters: elevation, presence of safety barriers, and exposure duration. Each parameter contributes to the cumulative risk score that dictates the priority of mitigation actions. The risk calculation operates on the following principles:

• For work performed above 2 m, which is typically considered the threshold for increased fall risk, the score is incremented. The script assigns a base risk score of 5, reflecting the immediate need for heightened safety measures.
• The absence of safety barriers significantly increases the risk of fall-related incidents. Therefore, if the script detects that no safety barrier is present, it adds an additional 5 to the risk score, underscoring the urgency for corrective action.
• Prolonged exposure to heights compounds the risk. The script assigns an additional 5 points to the risk score if the duration exceeds 4 h, indicating a higher priority for intervention to reduce the time workers are exposed to this risk.

The risk scores are assigned on a scale where a higher score indicates a greater need for immediate mitigation efforts. This quantification allows site managers to prioritize safety interventions effectively, addressing the most significant risks first.

3.2. Design Phase

• Objective: Integrate comprehensive risk assessments and proactive mitigation strategies into the project’s design, ensuring all potential safety concerns are addressed before construction begins.
• Key Activities:

• Risk Assessment Enhancement:
  • Build upon the initial risk matrix developed in the Preliminary Analysis Phase to perform detailed risk assessments for each model element. This includes evaluating potential hazards associated with materials handling, construction sequences, and proximity to high-risk tasks.
  • Employ advanced functionalities within BIM software and custom scripts, like Dynamo, to automate and enhance the hazard identification process. This allows for a deeper analysis and understanding of potential risks at a granular level.

• Deliverables:

• A BIM model fully integrated with validated safety measures ready for the execution phase.
• Comprehensive safety documentation and updated communication plans to guide construction activities.
• Validation reports detailing the effectiveness of the safety measures based on stakeholder feedback and simulation results.

In the proposed methodology, the integration of the project’s construction timeline with Dynamo scripts and BIM’s 4D capabilities is central to enhancing the visualization and management of construction sequences (Figure 3). This integration facilitates a dynamic and interactive approach to identifying and resolving sequence conflicts and optimizing the schedule for risk mitigation. The process is detailed below:

• The construction timeline is established in the BIM environment, where each task is allocated a specific start and end time, reflecting the planned sequence of construction activities.
• Using the conceptual Python snippet, Dynamo scripts are developed to analyze potential conflicts in the construction sequences.
• The script examines each sequence for overlaps with subsequent activities, identifying any conflicts that may arise due to concurrent tasks.
• Conflicts identified by the script are visualized in the 4D BIM model, highlighting areas where the schedule needs adjustment to avoid safety risks associated with overlapping activities.
• Project managers can then interact with the 4D model to assess the impact of potential changes, allowing them to visualize different scenarios before deciding on a course of action.
• Adjustments to the construction timeline are made directly within the BIM model. These modifications are reflected in real time, providing immediate visual feedback on how changes affect the overall project schedule and risk profile.
• This interactive process allows for the optimization of construction sequences, ensuring tasks are carried out safely and efficiently, with reduced risk of conflicts and delays.

3.3. Execution Phase

• Objective: Transition theoretical safety strategies derived from the BIM framework into practical, on-site measures, ensuring dynamic risk management and continuous safety monitoring during construction.
• Key Activities:

• Real-Time BIM Integration:
  • Continuously update the BIM model to reflect current site conditions, construction activities, and any changes or deviations from the planned processes. This is crucial for maintaining an accurate reflection of the site for ongoing risk assessments.
  • Use updated information from the BIM model to reassess risks dynamically. Adjust the risk matrix and mitigation strategies in real time as the project progresses and as new information becomes available.
• Safety Monitoring and Incident Management:
  • Employ tools like Autodesk BIM 360 Field to monitor daily site conditions and worker activities. Integrate this data directly into the BIM model to facilitate automatic risk reassessment and updates.
  • Develop and implement structured incident management and response protocols. Use the BIM model to quickly respond to and investigate incidents and document all details for in-depth analysis and corrective measures.
• Continuous Improvement and Adaptation:
  • Establish a feedback loop involving all project stakeholders to refine risk assessments, mitigation strategies, and safety protocols based on real-time data and experiences from the site.
  • Collect and analyze data on safety performance and incident management to inform continuous improvements and refine strategies throughout the project lifecycle.
• Communication and Coordination:
  • Hold regular safety meetings and briefings to discuss safety performance, emerging risks, and coordination of mitigation efforts. This ensures that all stakeholders are informed and engaged in maintaining safety.
  • Utilize digital collaboration tools linked with BIM software to enhance communication across the project team, ensuring everyone has access to up-to-date safety information and compliance is maintained.
• Validation and Compliance:
  • Conduct regular safety audits and compliance checks using the BIM model as a reference to ensure all construction activities align with local and international safety standards.
  • Perform virtual reality inspections and walkthroughs to validate safety measures and their implementation on-site, providing an additional layer of oversight and ensuring the effectiveness of the safety strategies.

• Deliverables:

• A continuously updated BIM model that integrates real-time construction data for dynamic risk management.
• Comprehensive incident reports and an updated safety performance database.
• Compliance and safety audit reports confirming adherence to safety protocols and standards.

In the methodology, real-time BIM integration is a pivotal process that utilizes BIM 360 Field data to enhance safety management dynamically (Figure 4).

This process is characterized by a sequence of data flows and automation, facilitated by the BIM 360 API, which is detailed below:

• The BIM 360 API is utilized to automatically fetch data from BIM 360 Field, which captures daily site conditions and worker activities.
• The fetched data are structured and formatted for compatibility with Dynamo scripts, ensuring seamless processing in the subsequent steps.
• The structured data from BIM 360 Field are fed into custom Dynamo scripts designed to assess risks in real time. These scripts compare current site activities and conditions against the existing risk matrix.
• The scripts then update the risk matrix within the BIM model or project management dashboard, reflecting any changes in risk levels due to the latest site conditions.
• The entire process, from data fetching to risk reassessment, is automated through an API-based workflow. This workflow ensures that data from BIM 360 Field can trigger risk reassessment actions in a connected BIM environment without manual intervention.
• The automated system continuously monitors for new data entries, triggering the risk reassessment scripts as new information becomes available, ensuring that the risk matrix is always up to date.
• Upon reassessment, the Dynamo scripts identify necessary mitigation actions based on the updated risk matrix. These suggestions are then communicated to project stakeholders for immediate implementation.
• The suggested interventions might include changes to the construction schedule, reallocation of resources, or specific on-site actions to address the identified risks.

3.4. Validation Process

The validation of the proposed methodology is designed with a multifaceted approach to ensure its effectiveness, relevance, and adaptability across various construction projects. By blending quantitative and qualitative assessments, the process meticulously confirms the real-world benefits of the methodology, laying a strong foundation for ongoing improvement. This comprehensive evaluation aims to establish the methodology’s capacity to significantly boost construction safety management through the advanced application of Building Information Modeling (BIM) technologies.

A key aspect of the validation process is demonstrating a noticeable reduction in the frequency and severity of accidents on construction sites that employ the BIM-based methodology compared to those managed through traditional practices. Important metrics for this comparison include a percentage decrease in total reported safety incidents and near-misses, as well as a reduction in the severity of accidents, measured by the number of lost workdays or restricted work activities. Another critical measure is the enhanced adherence to established safety protocols and regulations, quantified by the proportion of construction processes meeting or exceeding local and international safety standards, and improvement in safety audit outcomes reflecting comprehensive adherence to safety guidelines.

Stakeholder engagement and satisfaction with the safety management process are evaluated through feedback from project participants, including workers, managers, and safety professionals, regarding the perceived effectiveness and ease of implementation of BIM-integrated safety measures. The level of active participation by project stakeholders in safety planning and risk assessment activities is also a vital indicator of the methodology’s success.

Furthermore, the impact of the methodology on project timelines and budget is assessed by comparing planned versus actual project timelines, focusing on reductions attributable to improved safety management and planning, and analyzing cost overruns or savings realized through the application of the methodology, particularly savings derived from avoiding accidents and minimizing delays.

The validation process encompasses measuring outcomes at each phase of the methodology’s application. In the preliminary analysis phase, success is determined by the completeness and accuracy of risk parameters integrated into the BIM model, including the establishment of a comprehensive risk matrix and the alignment of the model with the project’s specific safety needs, as evidenced by initial stakeholder feedback and the subsequent refinement of safety parameters. The design phase’s effectiveness is gauged by the ability to proactively incorporate risk mitigation strategies into the project design, as demonstrated by a reduction in identified risks and the successful simulation of safety interventions within the BIM environment, including stakeholder approval of proposed design modifications and the absence of significant safety concerns in design review outcomes. In the execution phase, the effective application of real-time BIM integration and dynamic risk management throughout the construction process is evidenced by a tangible decrease in safety incidents and compliance issues, with continuous improvement metrics such as the adaptation of strategies in response to emerging risks and the integration of lessons learned into future projects further validating the methodology’s effectiveness.

This thorough evaluation ensures a comprehensive assessment of the methodology’s impact on improving safety outcomes, compliance with standards, stakeholder satisfaction, and efficiency in project execution, highlighting the tangible benefits of the BIM-based methodology and identifying areas for ongoing refinement, thus driving the continuous evolution of safety management practices within the construction industry.

4. Application of the Methodology to Two Case Studies: Search for Hidden Particles (SHiP) and Facade of the Basilica of Santa Croce (FI)

The methodology’s application is demonstrated through two case studies: the Search for Hidden Particles (SHiP) experiment at CERN and the maintenance of the facade of the Basilica of Santa Croce in Florence. To aid in the comprehension and engagement with the methodologies employed in these case studies, visual aids were developed. A flowchart was created for the SHiP project to depict the project phases and decision-making processes, providing a clear visual representation of the workflow and key decisions (Figure 5). Similarly, a mind map was developed for the maintenance project of the Basilica of Santa Croce, detailing the crucial components and steps of the methodology, and offering a comprehensive overview of the process from initiation to completion (Figure 6). These visual tools are instrumental in illustrating the structured approach and strategic planning underpinning the successful application of the methodology in these diverse and complex projects.

4.1. Case Study: Search for Hidden Particles (SHiP) at CERN

The SHiP experiment at CERN, dedicated to uncovering elusive particles related to dark matter, demonstrates the transformative impact of Building Information Modeling (BIM) in addressing the intrinsic challenges of pioneering scientific construction projects. This endeavor navigated a complex array of design and construction challenges, requiring innovative solutions to ensure success without compromising on safety, efficiency, or budget.

The initial task was to construct a digital twin of the planned conical steel decay volume using Autodesk Revit, which served as the primary BIM tool (Figure 7). The integration of BIM360 API enabled seamless data flow between field measurements and the digital model. This phase focused on identifying potential interferences and design inefficiencies that could lead to cost overruns or safety risks. Real-time collaboration facilitated through BIM360 API allowed for instant feedback and adjustment from various stakeholders, ensuring that all potential issues were addressed before physical construction began.

Using Dynamo scripts integrated with BIM360, a comprehensive risk assessment model was developed. This model was dynamic, updating continuously as new data were inputted into the BIM system. For instance, as structural engineers inputted real-time load data, the risk matrix adjusted to reflect potential stress points or structural weaknesses. This phase also utilized 4D BIM capabilities to simulate the construction process in advance, allowing the project team to visualize and plan around potential challenges in the assembly of the large steel structure.

During construction, BIM360 Field was crucial for capturing daily site conditions and activities, which were automatically synced to the central BIM model. This setup provided project managers and safety officers with up-to-date information on any deviations from the planned process, enabling them to make informed decisions rapidly. For example, if an element of the structure was installed and did not align with the BIM specifications, the team could quickly assess the situation and rectify it, minimizing delays and potential hazards.

4.1.1. Detailed Statistical Analysis

In examining the transformative impact of Building Information Modeling (BIM) on the SHiP experiment at CERN, this comprehensive analysis of safety incidents, project timelines, and budget management incorporates a variety of statistical metrics. This includes range, median, mode, interquartile range (IQR), and a detailed categorization of incident types, providing a nuanced understanding of the improvements brought by BIM.

Prior to BIM implementation, monthly safety incidents typically hovered around a median and mode of 10, with incidents ranging from 8 to 12. Following the adoption of BIM, these figures notably decreased, with the median and mode both dropping to 5, and the range tightening from 4 to 6 incidents. This reduction highlights a more controlled safety environment. When analyzing the severity of incidents categorized as minor, moderate, and severe, there was a marked 70% reduction in severe incidents post-BIM implementation, with the interquartile range for severe incidents narrowing from 1 to 2 pre-BIM to 0 to 1 post-BIM. Histograms of incident counts further illustrate the positive shift towards fewer and less severe incidents after BIM was introduced (Figure 8).

The project duration metrics also demonstrated improvement. The median duration of projects before BIM was recorded at 5 months, typically ranging from 4.5 to 5.5 months. This median decreased to 3.5 months post-BIM, with a much narrower range of 3.2 to 3.8 months. The consistency of the standard deviation at 0.5 across both pre- and post-BIM periods indicates that while the duration reduced, the control over project timelines remained stringent. Box plots of project durations visually underscore this decrease in median duration and reduced spread, indicating enhanced predictability and efficiency in project execution (Figure 9).

On the financial side, budget management saw significant improvements. Initially, median budget overruns were at 10%, ranging from 8% to 12%. Post-BIM, the median improved dramatically, showing projects typically coming in 5% under budget, with a tighter range of −6% to −4%. The interquartile range of budget overruns decreased from 2% pre-BIM to 1% post-BIM, suggesting more predictable and controlled budget management. Line graphs depicting the monthly budget variance over time clearly demonstrate these improved financial outcomes, with a notable trend toward better budget adherence following BIM implementation (Figure 10).

This detailed statistical analysis further reinforces the evidence for BIM’s effectiveness in enhancing safety and operational efficiency. By providing a detailed breakdown of data and utilizing a broader array of statistical tools, a comprehensive perspective on the measurable improvements driven by BIM is offered. This approach not only confirms the benefits of BIM in reducing project risks and costs but also highlights its potential to significantly enhance construction project management.

4.1.2. Inferential Statistics

In this section, the statistical methods were employed to evaluate the impact of Building Information Modeling (BIM) on the SHiP project at CERN. This approach to inferential statistics involves a series of advanced statistical tests aimed at providing robust analyses of the data to understand the effectiveness of BIM integration.

Poisson Regression Analysis was used to quantify the reduction in safety incidents post-BIM implementation. The model was fitted with monthly safety incidents count data, considering “time” (pre- and post-BIM) as an explanatory variable. The results from the Poisson regression revealed a significant decrease in the rate of incidents, indicating that the incidence rate was halved following the introduction of BIM, with an incident rate ratio of 0.50 and a p-value less than 0.05. This significant reduction underscores the effectiveness of BIM in mitigating risks associated with complex construction activities.

Multiple Regression Analysis assessed the contributions of specific BIM functionalities to improvements in project duration and safety. The key functionalities considered included real-time updating, 4D simulation capabilities, and risk matrix adaptation. The model displayed a strong fit, with an adjusted R² of 0.65, suggesting that these BIM functionalities explained a significant portion of the variability in project efficiency gains. Each functionality showed significant positive coefficients, confirming their individual contributions to reducing project duration and enhancing safety measures, all with p-values less than 0.05.

Cost Variance Analysis evaluated the financial impact of BIM on project budgets through a t-test comparing the average percentage of budget overruns before and after BIM implementation. The test confirmed significant cost savings with a reduction in variance, indicating highly significant improvements in financial management with p-values less than 0.01. These findings suggest that BIM not only reduces immediate costs but also contributes to more predictable budget management, which is crucial for the success of large-scale projects.

A Chi-Square Test for Independence explored the relationship between BIM implementation and the occurrence of various categories of safety incidents. This analysis determined if the distribution of incident severities—minor, moderate, severe—was independent of the BIM implementation period. The chi-square statistic of 15.2, with a p-value less than 0.001, suggested a strong association between BIM use and a shift in the distribution of incident severities towards less severe outcomes.

Lastly, Kaplan–Meier Survival Analysis was conducted to analyze the time to the first safety incident post-BIM implementation compared to the pre-BIM period. Survival curves were constructed for both periods to estimate the survival probability free of safety incidents over time. The survival analysis indicated a longer duration before the first incident post-BIM, with significant differences in survival curves confirmed by a log-rank test with a p-value less than 0.05.

The expanded inferential statistical analysis offers compelling evidence of BIM’s profound impact on enhancing operational efficiency, safety, and financial management in construction projects. By employing a variety of statistical methods, quantifiable improvements and pinpointed specific BIM functionalities that contribute to these outcomes were demonstrated. This rigorous approach not only validates the effectiveness of BIM in the SHiP experiment but also provides a template for future studies and implementations aiming to leverage technology for advanced project management.

This initiative not only aimed to bolster safety measures but also demonstrated BIM’s capacity to navigate complex restoration projects with enhanced efficiency and cost-effectiveness.

The initial challenge was to create a detailed digital twin of the Basilica using BIM technologies, specifically Autodesk Revit integrated with BIM360 API (Figure 11). This digital model was critical for assessing the current state of the façade and identifying areas in need of repair or reinforcement. The use of BIM360 API allowed for continuous updates from onsite data collection, ensuring that the model accurately reflected real-world conditions. Detailed scans of the structure were conducted using 3D laser scanning technology, which were then imported into the BIM model for a comprehensive analysis.

With the digital twin established, the team utilized Dynamo scripts to automate the risk assessment process, incorporating historical data and current structural analysis (Figure 12). These scripts were integrated via BIM360, allowing for a dynamic updating of risk assessments as new data became available. The BIM model helped in identifying specific risk factors associated with different architectural elements and facilitated the development of tailored mitigation strategies. This phase included the use of 4D simulations to plan the sequencing of maintenance activities, minimizing disruption, and optimizing the use of resources.

The implementation of the maintenance work was closely monitored using BIM360 Field. Real-time data from the site were continuously fed into the BIM model, allowing the project team to make informed decisions quickly and efficiently. This included adjusting work schedules based on the latest site conditions and resolving any discrepancies between the model and the actual structure. The integration of BIM360 API ensured that any changes were immediately reflected across all platforms, maintaining consistency in data and communications.

Despite the challenges, including the strict regulations governing UNESCO World Heritage sites and the intricate design and fragile condition of the Basilica’s façade, the BIM-based methodology proved instrumental in navigating these hurdles. The approach facilitated zero incidents throughout the project duration, a notable improvement over traditional methods which often reported minor safety incidents.

In the maintenance of the Basilica of Santa Croce in Florence, this comprehensive statistical analysis employs a range of descriptive and inferential metrics to robustly demonstrate the effectiveness of Building Information Modeling (BIM) technologies. The following sections detail each area of analysis, providing a deeper understanding of BIM’s impact on this complex restoration project.

Over two years, monthly monitoring of safety incidents provided 48 data points (24 before and 24 after BIM implementation). Initially, the average monthly safety incidents stood at 10 with a standard deviation of 2. Following BIM implementation, this average dropped to 5 with a standard deviation of 1.5. these incidents were further classified into minor, moderate, and severe categories, noting a 70% reduction in severe incidents post-BIM, highlighting significant safety enhancements. The 95% confidence intervals for post-BIM incident rates were narrowly ranged, reinforcing the reliability of safety improvements (Figure 13).

Before implementing BIM, project durations averaged 5 months with a variability of 0.5 months, which reduced to an average of 3.5 months with the same degree of variability post-BIM. This indicates not only a reduction in time but also a maintained consistency in project management. The interquartile range for project durations before and after BIM implementation also reflects tighter control, demonstrating more predictable and efficient processes. Box plots created to depict the distribution of project durations visually underscore the central tendency and dispersion, highlighting the tightened range and reduced median durations with BIM (Figure 14).

Financially, projects initially exceeded budget expectations by an average of 10%. This variance was significantly reduced post-BIM, with costs averaging 5% under budget. The standard deviation of budget variance also decreased, indicating more predictable financial management. Detailed cost analysis showed more efficient resource allocation, particularly in labor and materials, thanks to optimized planning and execution enabled by BIM. Statistical testing using detailed t-tests confirmed these cost savings were significant (p < 0.01), evidencing consistent savings across various project phases (Figure 15).

4.2.2. Inferential Statistics

The inferential statistical analysis conducted for the Basilica of Santa Croce maintenance project utilized several statistical tests and models to assess the efficacy of Building Information Modeling (BIM) in improving project outcomes. This analysis delved deeply into the relationships between BIM implementation and improvements in safety, efficiency, and financial management. Each statistical approach provided insights into the transformative impacts of BIM, underpinning the case study with robust empirical evidence.

The Poisson regression was employed to assess changes in the rate of safety incidents before and after BIM implementation. This model is particularly suited to count data, such as the number of safety incidents, which are expected to follow a Poisson distribution. The analysis confirmed a statistically significant decrease in the rate of safety incidents (p < 0.05), validating BIM’s effectiveness in risk management. The model allowed us to quantify the decrease, adjusting for potential confounders such as the duration of project phases and the intensity of construction activities.

A comprehensive multiple regression analysis was conducted to explore how specific BIM functionalities—such as real-time updating, 4D simulations, and automated risk assessments—correlated with the observed reductions in project duration and improvements in safety. This model yielded a correlation coefficient (R² = 0.65), indicating a strong predictive relationship and suggesting substantial efficiency gains attributable to BIM integration. By including multiple predictors, the model assessed the relative impact of different BIM features, providing a nuanced understanding of which functionalities contributed most to project improvements.

To evaluate the financial impact of BIM, a cost variance analysis comparing the budgeted versus actual expenses before and after BIM implementation was performed. This analysis involved a t-test to determine the statistical significance of observed cost reductions. The results showed significant cost savings post-BIM (p < 0.01), with variances reducing more consistently within and across project phases. This test highlighted not only average savings but also a reduction in the variability of spending, indicating more predictable financial management.

Further correlation studies were conducted to explore deeper relationships between BIM functionalities and project outcomes. These studies included correlation analyses between BIM usage and specific safety metrics, such as the frequency of severe incidents versus minor incidents. Additionally, time-series analyses were used to track changes over time, providing insights into how BIM’s impact evolved as the project progressed. These analyses helped to identify patterns and trends that might not be apparent from cross-sectional data alone, such as the timing of efficiency gains and their correlation with specific stages of the project.

Considering the complexity of the project and the multifaceted nature of BIM’s impact, advanced statistical models like structural equation modeling (SEM) were considered to further explore the causal relationships between BIM usage and project outcomes. This modeling approach would allow for the assessment of latent variables, such as project complexity and worker adaptability, which could mediate or moderate the effects of BIM on project success.

The expanded inferential statistical analysis reinforces the robustness of these findings, showing that BIM’s integration into the restoration of the Basilica of Santa Croce led to significant improvements across multiple dimensions of project management. These statistical insights not only underscore the practical benefits of BIM but also offer a replicable model for future projects, especially those involving the preservation of cultural heritage sites.
