1. Introduction
The construction industry serves as a cornerstone of the socioeconomic development of nations, playing a significant role in wealth and well-being generation across countries. With its contribution to the Gross Domestic Product (GPD) ranging between 3% and 9%, the industry’s economic impact is undeniably substantial [
1,
2,
3]. Despite its critical importance, the construction sector has historically exhibited insufficient progress in productivity, especially when compared to other industrial sectors. Over the past two decades, the annual average growth rate of labor productivity in construction has barely reached 1%, a figure significantly lower than the 2.8% growth rate for the global economy and 3.6% for the manufacturing industry [
4,
5]. This stagnation underscores a pressing need for innovative approaches to project management within the construction industry.
Advanced work packaging (AWP) is a methodology that has the potential to optimize execution and enhance predictability in project management. AWP represents a paradigm shift, promising to revolutionize project management and execution through automated information extraction for improved constraint management, thereby facilitating more efficient identification and modeling of constraints [
6]. Its capabilities underscore the method’s potential to address the construction industry’s productivity woes effectively [
7]. AWP aligns project planning and execution from initiation through closing, organizing projects into manageable packages that facilitate better planning, coordination, and execution [
8,
9]. This approach has generated quantifiable improvements, including up to a 10% reduction in total installation costs, a 25% enhancement in labor productivity, and significant safety and quality standards advancements [
10,
11].
However, despite the promising advantages of AWP, its seamless integration into the broader project-management framework faces significant barriers. These challenges not only impede AWP’s adoption but also highlight the gap between theoretical understanding and practical application within the industry [
12]. A comprehensive exploration of these barriers remains a critical need, underscoring the potential benefits of such an endeavor. By identifying and analyzing the obstacles to AWP adoption, valuable insights can be gleaned regarding the challenges construction-industry professionals encounter when implementing this innovative methodology.
This study aims to bridge this knowledge gap through a systematic literature review (SLR), intending to identify the expected barriers to adopting AWP in the construction sector. Employing the “Preferred Reporting Items for SLR and Meta-Analyses” (PRISMA) guidelines, this SLR seeks not only to elucidate these barriers but also to offer a clear and methodologically sound exploration of the existing literature [
7,
13]. The significance of this study lies in its contribution to the construction-management discipline’s body of knowledge, offering both practical implications for industry stakeholders and a foundation for policy development aimed at facilitating AWP adoption. By fostering a deeper understanding of AWP’s barriers, the construction industry can develop strategies to overcome these challenges, thereby driving innovation and progress within the sector.
2. Research Methodology
This study rigorously investigates the adoption barriers of the AWP methodology within project management through a structured three-stage approach, adhering to established SLR practices. The methodology unfolds as follows (as shown in
Figure 1).
The research commences with a bibliometric analysis to systematically sift through the extensive corpus of the AWP literature. According to the PRISMA guidelines, this covers three main phases to identify the pool of references to be included in the final analysis. As shown in
Figure 2, these phases are the identification of the search sources and inclusion and exclusion criteria, screening of the results, and making the decision to identify the eligible studies. Commencing with the “Identification” phase, a total of 283 records were ascertained through comprehensive searches in esteemed databases such as Google Scholar, Scopus, Web of Science, and the American Society of Civil Engineers. In parallel, four additional records were sourced from other unspecified avenues, rendering an aggregate of 287 initial records. In the “Screening” phase, duplicates were meticulously eradicated, resulting in a curated set of 212 records. Of this ensemble, 105 records were shortlisted after a rigorous screening, while 107 were dismissed, though the specific reasons for such exclusions remain unstated in the flowchart. In the “Eligibility” phase, the 105 shortlisted records underwent a thorough examination of their full texts. Forty-six articles were discarded based on explicit criteria: they referenced AWP superficially or AWP was named merely to acknowledge its existence. Conclusively, the “Included” phase signifies the culmination of this rigorous selection process, with 59 studies deemed suitable for a qualitative synthesis. These selected studies presumably shed valuable light on the research’s focal themes, including the barriers’ relationships, AWP application, and theoretical aspects of AWP.
Subsequently, a scientometric analysis is undertaken to dissect and visualize the academic discourse surrounding AWP. This stage focuses on mapping out the coauthorship and keyword co-occurrence networks, illuminating the collaborative and thematic landscape. The analysis reveals influential authors, seminal works, and the evolution of research themes over time, corresponding to the screening phase, where studies are assessed based on inclusion and exclusion criteria determined beforehand. This step is crucial for filtering the literature to those studies most pertinent to the review’s objectives, ensuring that the analysis is both focused and relevant [
14].
The final stage delves into the classification and in-depth analysis of barriers to AWP adoption, as discerned from the literature. Manual screening of the literature information refines the selection, isolating critical texts that address AWP implementation challenges. Insights from this analysis lead to synthesizing comprehensive recommendations for overcoming these barriers and highlighting future research trends.
3. Results and Analysis

Finally, “Communication and Knowledge Management Aspects” includes barriers such as trust deficits, inadequate knowledge management, poor communication, and the need for cultural and technological change.
3.4.1. Technical and Management Challenges
The category of “Technical and Management Challenges” encompasses a spectrum of barriers that impede the seamless implementation of AWP. A critical barrier within this domain is the complexity of constraint management in project environments, particularly in scenarios such as bridge rehabilitation, where manual oversight remains prevalent [
6,
42]. Additionally, the integration of comprehensive knowledge bases into AWP processes presents a significant challenge, as indicated by the repeated identification and modeling of constraints, which are often performed manually and underscore a lack of automation in the integration of information into project knowledge bases [
6,
42].
These challenges are further exacerbated by a pervasive reliance on manual management, which not only hampers efficiency but also serves as a testament to incomplete knowledge bases that are crucial for informed decision making [
42]. The intricate management of these constraints, coupled with an overarching need for robust knowledge bases, underscores the necessity for a shift towards more sophisticated and automated systems that can enhance the efficacy of AWP adoption [
42].
Furthermore, the sector is witness to an inherent complexity in the AWP process itself, necessitating extensive resources and organizational change implications [
9]. This is not a stand-alone barrier but rather a multifaceted issue that interacts with the need to adjust existing operational logic schemes and manage work package definitions, as articulated by [
37]. Such adjustments require not only a change in operational procedures but also a shift in mindset, which can be particularly challenging in established project management frameworks [
9,
42].
3.4.2. Organizational Resistance and Cultural Change
Under the category “Organizational Resistance and Cultural Change”, the implementation of AWP confronts significant barriers rooted in the human and cultural dimensions of organizational environments. The resistance to change emerges as a recurring theme, reflecting a deep-seated inertia within the corporate culture that is resistant to new methodologies, not only AWP but also many other practices and philosophies, such as lean construction, digital transformation, and others [
7,
23,
66,
67,
68,
69,
70,
71]. This resistance is often coupled with concerns about disclosing trade secrets, which can inhibit the sharing of information necessary for effective AWP implementation [
23].
The nature of the construction industry itself, characterized by its conservative disposition, further complicates the adoption of AWP. This sector’s proclivity for maintaining traditional practices challenges the integration of innovative project-management approaches [
7,
15]. Moreover, the retention of a skilled workforce becomes a formidable challenge in an industry where transient employment is common, which can disrupt continuity and the knowledge retention critical for AWP’s success [
23].
Organizational change implications are pronounced when implementing AWP, as it demands not only procedural adjustments but also an overarching transformation in organizational structures and mindsets [
9]. The need for a strong change-management component is vital, given the new integration and project management practices introduced by AWP [
29]. Additionally, the barriers extend to conflicting interests among stakeholders and incompatibilities with certain contractual scenarios, which underscore the complexity of managing change within diverse organizational frameworks [
8].
These organizational and cultural impediments necessitate a strategic approach to change management, where the focus is on facilitating the transition through education, leadership, and a re-evaluation of corporate values to embrace the benefits of AWP [
8,
23,
29].
3.4.3. Integration of Methodologies and Tools
The category “Integration of Methodologies and Tools” underscores the multifaceted barriers encountered in harmonizing AWP with existing project management tools and methodologies. A key obstacle is the necessity to recalibrate operational logic schemes to accommodate AWP, which often involves a redefinition of work-package structures and processes [
37]. This recalibration necessitates a thoughtful reexamination and restructuring of current practices, which can be a strenuous process for organizations accustomed to established procedures.
Furthermore, the integration of AWP with other methodologies, such as Lean Construction (LC), is met with criticism from practitioners who highlight deficiencies such as the lack of attention to buffers and practical effectiveness [
58]. These criticisms point to the need for a more nuanced approach that addresses the specific workflows and cultural elements inherent in different methodologies.
The challenge extends to the adaptation of the Last Planner System
® (LPS) to integrate seamlessly with WorkFace Planning, a component of AWP. The available literature on this integration is limited, indicating a gap in research and guidance [
35]. This paucity in the literature not only impedes theoretical understanding but also practical application, making it difficult for practitioners to adopt AWP confidently.
This suggests a pressing need for a concerted effort to develop integrative tools and methodologies that are flexible, adaptable, and responsive to the nuances of AWP. Such development should be informed by both empirical research and practical experiences to ensure that the integration of AWP into existing project-management frameworks is both seamless and effective [
29,
35,
37,
58].
3.4.4. Training and Professional Development
The “Training and Professional Development” dimension is a critical component in the successful implementation of AWP, as it addresses the educational and skill-related barriers present in the industry. A prevalent challenge is the necessity for ongoing training and updates for stakeholders across all project phases to effectively implement AWP and related methodologies [
51]. This requirement underscores the continuous nature of professional development that is needed to keep pace with evolving project management practices.
Malhorta [
27] identifies the underutilization of Construction Industry Institute (CII) Best Practices in sectors such as Upstream, Midstream, and Mining (UMM), attributing this to an incomplete understanding of these practices among professionals. This gap in knowledge presents a barrier to adopting AWP, as these best practices form the foundational knowledge required for its application.
Furthermore, the adoption of Building Information Modeling (BIM) in conjunction with AWP necessitates a significant shift in organizational culture and technology, with an acute need for change catalysts and champions to drive the implementation. The transition to BIM/AWP is not merely a technical upgrade but also a cultural transformation that demands a strategic approach to training and development [
6,
30,
38,
42].
The lack of familiarity with AWP among contractors amplifies the need for targeted strategies to introduce AWP methodologies [
46]. The development of such strategies would facilitate a more profound understanding of AWP and its benefits, promoting its broader acceptance and application. Furthermore, the establishment of ongoing educational programs, mentorship initiatives, and leadership endorsement are vital to fostering an environment conducive to learning and adaptation, enabling the effective deployment of AWP [
27,
46,
51].
3.4.5. Planning and Coordination Aspects

10] notes the intricate task of managing multiple disciplines within confined spaces, emphasizing the necessity to deconstruct work areas both horizontally and vertically to ensure efficient workflow. This approach requires not only careful planning but also a sophisticated understanding of space utilization concerning project timelines.
Furthermore, the barriers to AWP adoption are compounded by the complexity of breaking down and sequencing work into packages that align with the project’s schedule and resource allocation. It involves a detailed understanding of the project deliverables and the engineering work sequence, which can be significantly different when AWP is applied [
28,
72].
The planning and coordination aspects of AWP, as highlighted by these studies, call for an integrated approach to project management that facilitates seamless communication and collaboration across all project phases and disciplines [
10,
28,
39,
57].
3.4.6. Perceptions and Practical Effectiveness
The “Perceptions and Practical Effectiveness” category delves into the evaluative aspects of AWP concerning its reception and real-world application. Ganesh et al. [
58] details the scrutiny from Lean Construction practitioners who question AWP’s practical effectiveness, highlighting a perceived deficiency in addressing workflow buffers. This critique points to a misalignment between the theoretical constructs of AWP and the tangible outcomes experienced on the ground.
In addition, [
49] discusses the challenges of inadequate coordination between project teams and construction personnel. The restructuring of work to accommodate AWP can be mitigated with a proactive stance between engineering and construction planning, yet this requires a practical approach to collaboration that may not be inherent in current practices.
These insights reveal a critical need for a reassessment of how AWP is perceived and applied within the construction industry. It is imperative to bridge the gap between the method’s theoretical benefits and the actual results achieved in practice. Such alignment would not only enhance the credibility of AWP but also ensure its methodologies are effectively leveraged to improve project outcomes [
35,
49,
58].
3.4.7. Research Limitations and Empirical Evidence
The “Research Limitations and Empirical Evidence” segment addresses the critical concerns related to the scope and substantiation of research within the AWP field. Halala and Fayek [
40] underscores the scarcity of quantitative evidence to substantiate the reported benefits of AWP, signifying a gap between anecdotal success stories and empirical data. This lack of robust evidence impairs the ability to validate AWP’s efficacy and may deter organizations from adopting the methodology.
Injal [
31] draws attention to the limitations in generalizing results from specific case studies, such as those conducted within Citec, pointing to a potential over-reliance on limited data sets that do not reflect the broader industry. This limitation is compounded by a focus on initial project stages and a restriction to engineering work, which may not capture the full spectrum of AWP’s applicability.
Farghaly and Soman [
12] highlights a similar concern, pointing out the absence of a clear relationship in the literature between information management and AWP. This ambiguity hinders the development of a comprehensive understanding and the establishment of best practices that are grounded in solid research.
These limitations suggest a pressing need for more rigorous and expansive research that encompasses diverse project types and stages. Such research should seek to provide a robust empirical foundation for AWP, enabling a clear demonstration of its benefits and a more thorough understanding of its application across the construction industry [
12,
31,
40,
57].
3.4.8. Communication and Knowledge-Management Aspects
In the domain of “Communication and Knowledge Management Aspects”, the implementation of AWP is frequently impeded by barriers related to the dissemination and utilization of knowledge within organizations. Abdelghani [
15] highlights a collection of such barriers, including the conservative nature of the construction industry, resistance to adopting new technology and management principles, and the pervading issues of trust, inadequate knowledge management, and poor communication. These challenges are often a reflection of deeper cultural and structural issues within organizations, where established norms and practices may inadvertently stifle the flow of information and knowledge sharing necessary for AWP [
15]. The industry’s conservative approach frequently leads to a reluctance to share trade secrets or to adopt new technologies, further exacerbating the problem.
Lorys [
26] also identifies variability in productivity factors across different projects and the difficulty in reporting consistent construction progress as additional barriers. This inconsistency can lead to skepticism towards new methodologies like AWP and reluctance from clients to embrace new construction strategies.
The issues surrounding communication and knowledge management necessitate a strategic approach that prioritizes the development of trust, the establishment of effective communication channels, and the implementation of robust knowledge-management systems. Such strategies are crucial for the successful adoption of AWP, ensuring that knowledge is not only available but also effectively disseminated and utilized across all levels of an organization [
15,
26,
57].

The integration of new methodologies and tools, coupled with effective communication strategies and robust knowledge-management systems, will be essential in navigating the challenges identified.
Furthermore, the need for empirical research to substantiate the benefits of AWP and to generalize its applicability across different project types and contexts is paramount. This calls for a more data-driven approach to AWP research, ensuring that the methodology’s efficacy is grounded in solid empirical evidence.
This SLR contributes significantly to the existing body of knowledge on AWP. It offers a novel perspective on the challenges associated with AWP implementation and lays the groundwork for future scholarly endeavors in this domain. The study’s findings and recommendations provide a foundation for researchers, practitioners, and industry stakeholders to collaboratively address these challenges, paving the way for more effective and efficient project-management practices in the construction industry.
The current work is not free of limitations. The first limitation is the used methodology, which is the SLR approach. The findings of this study were extracted from the found studies in the literature. No numeric analysis has been conducted to analyze the most serious barriers that may face the adoption of AWP in the construction sector. Therefore, using other methods to collect quantitative or qualitative data (e.g., surveys, interviews, or focus groups) is recommended to answer this important question. Secondly, during the literature survey, the study included various types of publications (i.e., journal articles, conference articles, technical reports, and theses). While this seems very inclusive to cover various views and many ideas about AWP, it does not guarantee the exclusion of non-peer-reviewed results. This is due to the low number of peer-reviewed publications about AWP. This agrees with the above-mentioned barriers concerning the research limitations. Accordingly, the same study can be conducted in the future when more peer-reviewed publications about AWP are available. Lastly, the current study presents various strategies to support the proper adoption of AWP in the construction sector. However, due to the lack of numerical assessment tools, the study does not prioritize any of these strategies, nor does it investigate the expected challenges that may face these strategies. Answering these questions might be an essential need to ensure the successful implementation of AWP.
